5 3 City of Burnaby Annual Drinking Water Quality Report INTRODUCTION This report provides an overview of the regulatory context, outlines the drinking water quality program for 2013 and associated sample results to provide evidence of potability and compliance with the British Columbia Drinking Water Protection Regulation. REGULATORY CONTEXT Drinking water in the City of Burnaby (the City) falls under the regulatory jurisdiction of several government agencies: PROVINCIAL/FEDERAL REGULATORY REQUIREMENTSS The British Columbia Drinking Water Protection Regulation promulgated under the Drinking Water Protection Act requires, amongst other aspects, suppliers of drinking water in British Columbia to hold an Operating Permit, demonstrate that the drinking water is appropriately treated and monitored from microbial perspective, have appropriate emergency and public notification plans in place, and prepare and make public an annual report on the results of previous year. In addition, the Federal Guidelines for Canadian Drinking Water Quality provide references for acceptable concentration values for various chemical and physical parameters for potable water. REGIONAL HEALTHH AUTHORITY REQUIREMENTS In 2000, a "Water Quality Monitoring and Reporting Plan forr the GVRD and Member Municipalities" (WQMRP) was established by the Regional Medical Health Officials, the Greaterr Vancouver Water District and member municipalities. This document, which was reviewed and amended in January 2006, is a cornerstone in providing regional consistency in the monitoring and reporting of bacteriological and chemical drinking water quality parameters. In order to avoid duplication, the WQMRP separates the responsibilities for water quality monitoring and reporting between the GVRD (now Metro Vancouver) and the member municipalities by generally assigning the responsibility of source water and reporting to the Metro Vancouver and the responsibility for distribution system monitoring and reporting to the municipalities. 2013

6 4 City of Burnaby Annual Drinking Water Quality Report METRO VANCOUVER REQUIREMENTS In addition to the WQMRP the Drinking Water Management Plan (DWMP) was adoptedd in 2005 to ensure that our region s water needs will be met affordably and sustainably for Metro Vancouver and its member municipalities. In 2007, the Plan was amended to fully incorporate management of the source watersheds. In June 2011, the Plan was updated again detailing the investments in water treatment, supply and conservation programs necessary to provide consistently higher quality drinking water, improved supply reliability, and greater environmental protection. Details of the Plan and the municipal actions identified and adopted by the City are posted onn the Metro Vancouver website at:

7 5 City of Burnaby Annual Drinking Water Quality Report DRINKING WATER SYSTEM Metro Vancouver draws its water from Capilano, Seymour and Coquitlam sources and distributes it through its waterworks systems to member municipalities after treatment. As a part of the provision for treating water, Metro Vancouver uses chlorine as a primary disinfectant for Seymour and Capilano source waters. Coquitlam source water uses ozone as primary disinfectant. These source waters are subsequently re chlorinated at various regional secondary disinfection facilities installed in The disinfectant dosages are monitored at the regional chlorination facilities using on line potentiometric chlorine analyzers. Figure 1 shows an aerial shot of Metro Vancouver s source water. Figure 1 Metro Vancouver Source Watershed (photoo credit: metrovancouver.org) 2013

8 6 City of Burnaby Annual Drinking Water Quality Report SOURCE WATER QUALITY MONITORING Metro Vancouver undertakes comprehensive biological and chemical monitoring of the water while it is in their system. Source water monitoring recommended in the WQMRP includes monitoring for: Total Coliform, E. Coli, Heterotrophic Plate Count ( HPC), turbidity, pesticides, herbicides, all chemical parameters listed in the Guidelines for Canadian Drinking Water Quality, and Giardia and Cryptosporidium in water at the water supply intakes. In addition, Metro Vancouver also monitors its transmission mains and reservoirs for indicator organisms (Total Coliforms, E. Coli, and HPC), and a limited number of chemicals (free chlorine residual, PAH s and BTEX) water quality results for Capilano, Seymour and Coquitlam watersheds can be found in Appendix B. SOURCE WATER QUALITY REPORTING The Metro Vancouver staff presented the annual report on water quality to the Metro Vancouver Utilities Committee on May 23 th, 2014 to meet the requirement for water suppliers as per the Drinking Water Protection Regulation and as described in the Water Quality Monitoring and Reporting Plan. Summary and highlights of the regions water quality monitoring for 2013 can be found in their publication The Greater Vancouver Water District Quality Control Annual Report 2013, Volume I (Appendix B) and Volume II provides Chemical and Physical Monitoring resultss (full tabulation of data). In an effort to reduce paper usage, the printing of Volume II has been limited by Metro Vancouver to provide hard copy to specific individuals. Volume II will be made available to others if requested, either in hard copy or electronically. Requests for Volume II should be directed to the Water Quality Enquiry Line at This publication is available at public libraries and is also posted in the Metro Vancouver s web site

9 7 City of Burnaby Annual Drinking Water Quality Report WATER CONSERVATION Here in Burnaby, surrounded by waterways and with our mild, wet winters, it' 's easy to forget that water is a precious and limited resource. On average, Lower Mainland residents use more than 340 L per day for activities such as washing dishes and clothes, showering, flushing toilets, lawn sprinkling and other outside activities. With our climate and accessible resources, it's easy to take water for granted. Water conservation n is important for: o o o Ensuring sufficient drinking water supplies through the year, for when low snow pack levels and long, hot summers prevent our reservoirs from a full recharge. The Capilano, Seymour and Coquitlam reservoirs are filled by rain and snowmelt Meeting the demands of a growing population and delaying (or eliminating) the need for costly upgrades in the future Reducing waterfront pollution by minimizing how much waste water is generated Figure 2 How do you use your water? (image from Metro Vancouver) 2013

10 8 City of Burnaby Annual Drinking Water Quality Report The City of Burnaby encourages residents to use waterr sustainably to protect our water supply, conserve energy, and help reduce personal utility costs. Water use can typically be reducedd with a few simple changes: o o o o o o o o o Turn off the tap while brushing your teeth or washing dishes Use a City Rain Barrel to collect rain water for use in gardens and planters Watering lawns sparingly or not at all saves up to 17,000 litres per household over the summer months Spring loaded garden hose nozzles save 23 litres per minute Full loads and shorter cycles in the laundry room save 95 litres per load Low flow toilets save six to 14 litres per flush Toilet inserts save up to 100 litres per day Aerator and flow restrictors on the kitchen tap save up to 20 litres per day Fixed leaks in kitchen and bathroom taps save 47 litres perr day Water Conservatio n in a Rainforest? It rains a lot in our region; over 1 metre per year in some neighbourhoods. But not in July, August and September. These are the same months we like to water our lawns. A healthy lawn needs only one hour of rain or sprinkling per week. The City of Burnaby and other member municipalities of Metro Vancouver have Lawnn Sprinkling Regulations in place to help conserve water in the summer months, when we use water faster than our reservoirs can refill. More details on the Lawn Sprinkling Restrictions are available at

11 9 City of Burnaby Annual Drinking Water Quality Report DISTRIBUTION SYSTEM The City receives its treated water from Metro Vancouver and distributes it through a series of reservoirs and a network of pipes to the consumers. In order to ensure potability of the water at the point of supply, the City has a comprehensive program consisting of water quality monitoring, routine uni directional flushing of water mains, cross connection control and reservoir exercising. INFRASTRUCTURE The City s water system consists of four water pump (or booster) stations, four active water storage reservoirs (storage capacity 13.0 ML), twenty (20) pressure reducing stations, twenty ondollars. (21) pressure zones and over 700 km of watermains valued at over 490 million The City has a water main replacement program (average age of pipe is 29 years) to replace aging water mains at a rate of about 2% a year (approximately 15km per year), and a program to install dedicated sampling kiosks at sampling locations. CROSS CONNECTION CONTROL PROGRAM The City s cross connection control program works to ensure the potable water supply is protected from contaminationn in the event of back siphonage or back pressure. The City requires that appropriate backflow preventers are installed and tested annually as prescribed in the City of Burnaby Plumbing Bylaw # Regulations for the cross connection control can be found in the British Columbia Plumbing Code. 2013

12 10 City of Burnaby Annual Drinking Water Quality Report WATER QUALITY MONITORIN NG PROGRAM In 2013, there were 63 water quality sample locations in Burnaby (detailed in Appendix A). These sample locations were selected on the basis of determining water quality in various pressure zones, dead ends, reservoirs, feed lines from the Metro Vancouver water mains, residences and institutions. These locations were grouped into four routes for sample collection purpose. Water samples were collected on average twice a week on a 2 week sample location cycle. At the time of sample collection, free chlorine residual, turbidity and temperature of water were measured using field test kits. In addition, Metro Vancouver also collected samples from 15 sitess from its transmission mains in the City (detailed in Appendix A). The collected samples were submitted to the Metro Vancouver Laboratory for analysis. The Metro Vancouver Laboratory is a member of the Canadian Association of Environmental Analytical Laboratories (CAEAL), is accredited by the Standards Council of Canada (SCC) and is also approved by the Provincial Medical Health Officer for potable water testing. 2013

13 11 City of Burnaby Annual Drinking Water Quality Report A total of 2,987 routine drinking water samples were obtained in 2013 for bacteriological analysis. These included 1,5999 samples collected from City sample sites and 1,388 samples collected from Metro Vancouver transmission line sites located within the City boundary (see Appendix A for details) ). The average number of samples collected for bacterial monitoring by the City every month was over 115 andd is well above the 103 monthly sample requirement stipulated in the B.C.

14 12 City of Burnaby Annual Drinking Water Quality Report The water sampling frequency for microbiological characterization of the potable water is stipulated in Schedule B of Guidelines for Canadian Drinking Water Quality to be as follows: Table 1 Schedule B Frequency of Monitoring Samples for Prescribed Water Supply Systems Population Served Less than 5,000 5,0000 to 90,000 More than 90,0000 Number of Samples Per Month 4 1 per 1,000 of population 90 plus 1 per 10,0000 of population in excess of 90,000 From a reporting perspective, FHA was provided with the drinking water quality results directly by the Metro Vancouver laboratory at the same time as the results were sent to the City. It is to be noted that information regarding sampling locations, sample frequency, sample collection methodology, sample parameterss and the laboratory to be used for sample analysis were submitted and accepted by the regulatory agency. PHYSICAL PARAMETERS The physical parameters tested for in the City ss water distribution system include temperature and turbidity. TEMPERATURE Water temperaturee in the distribution system is dependent on the seasonal temperature variation experienced by the source water. The Guidelines for Canadian Drinking Water Quality set the aesthetic objective at less than 15 C for drinking water temperature. Temperatures above 15 C can impact aesthetic properties of taste, colour and odour. Temperature is also related to the microbiological characteristicss of drinking water through its effect on water treatment processes, especially disinfection, and its effect on the growth and survival of micro organisms. 2013

15 13 City of Burnaby Annual Drinking Water Quality Report The average water temperature in the distribution system remained well below the aesthetic maximumm objective of 15 C throughout mostt of the year. The average temperature peaked in August at 17.2 C. Samples did not show an increase in bacteriological growth, indicating that effective chlorine disinfection was achieved Aesthetic Objective (<15 ) Temperature C Figure Average Monthly Water Temperatures in the Distribution System TURBIDITY Turbidity is a measure of the relative clarity or cloudiness of water caused by fine suspended matter such as clay, silt and organics. Turbidity is not a direct measure of these particles, but rather a general measure of the effect these particless have on light. Elevated turbidity may be attributed to source water conditions or other transient activities which causes a change in the water pressure or flow in the system. These activities include water main flushing, water main breaks, or fire fighting. In an event that a sample indicated a high turbidity reading, follow up with the FHA and immediate flushing of applicable watermain(s) and resampling would be undertakenn as appropriate. 2013

16 14 City of Burnaby Annual Drinking Water Quality Report In 2013, the majority (99.7%) of the samples obtained had turbidity <1 NTU. Four (4) samples (0.25%) had turbidity between 1 2 NTU and one (1) sample (0.06%) had turbidity between 2 3 NTU, zero (0) samples had turbidity between 3 5 NTU and zero (0) samples had a turbidity >5 NTU. The average turbidity in Burnaby s water system is seasonally constant as shown in Figure 5 below Turbidity (NTU) Guideline (< 1 NTU) Figure Monthly Average Turbidity Levels in the Distribution System CHEMICAL PARAMETERS Water in the City s distribution system is also tested for chemical parameters of ph, chlorine, disinfection by products (Haloacetic Acids and Total Trihalomethanes), metals and vinyl chloride. PH The ph levels of water at the select sample location were representative of the ph of source water. The water sample was 7.1, meeting the Aesthetic Objective of 6.5 to 8.5 noted in the Guidelines for Canadian Drinking Water Quality. 2013

17 15 City of Burnaby Annual Drinking Water Quality Report CHLORINE RESIDUAL Chlorine is used to disinfect the water and safeguard against any microbial re growth or contamination in the distribution system. The Guidelines forr Canadian Drinking Water Quality recommends a minimum chlorine residuall of 0.2 mg/l. Sixty one of the sixty three sampling stations achieved the objective of 0.2 mg/l or above in 2013 on average. Sampling sations thatt experiencee temporary lower residual chlorine are largely due to low flow/use through the distribution system. The City maintains the residual chlorine levels in thesee areas by frequent flushing of the watermains to enhance flow. DISINFECTIONN BY PRODUCTS Disinfection by products are compounds formedd by the interaction between chlorine and naturally occurring organic substances in the water such as decaying leaves and vegetation that enter the source water naturally. The disinfection by products, measured as Trihalomethaness and Haloacetic Acid were found to be below the Maximum Acceptable Concentrationn (MAC) value of 100 parts per billion and 80 parts per billion, respectively noted in the Guidelines for Canadian Drinking Water Quality (Table 2). 2013

21 19 City of Burnaby Annual Drinking Water Quality Report BACTERIOLOGICALL QUALITY The bacteriological monitoring conducted regularly by the City includes testing heterotrophic plate count (HPC), total coliform and E.coli. HPC and total coliform indicator tests that report specific groups of biological activity in a sample. for are HETEROTROPHIC PLATE COUNT Heterotrophic Plate Count (HPC) is measured to monitor the system for early bacterial re growtdecreasing over the last ten years (Figure 4). While bacteriological re growth in late in the water distribution system. The annual average levels of HPC have been summer and fall period is still occurring (due to warmer water temperatures), it is to a much lesser extent than in previous years. Continued effort in unidirectional flushing of water mains and maintaining free chlorine residual objectivee of 0.2 mg/ L helps keeping the low HPC levels Annual Average HPC Values, CFU/mL HPC Regional Rechlorination Started Unidirectional Flushing Begins Annual Average Residual Chlorine Levels, mg/l Figure 6 Improvements in Water Quality in Distribution System ( ) 2013

22 20 City of Burnaby Annual Drinking Water Quality Report TOTAL COLIFORM AND E. COLI For a waterworks system to be in compliance, thee potable water sample must meet the following standards set out in Schedule A of the BCDWPA for the parameter tested: Table 4: Schedule A Water Quality Standards for Potable Water Parameter Standard Fecal coliform bacteria Escherichia coli No detectable fecal coliform bacteria per 100 ml No detectable Escherichia colii per 100 ml Total coliform bacteria a) b) No more than 10% of the samples in a 30 day period should be positive for total coliform bacteria when more than one sample is collected No sample should contain more than 10 total coliform bacteria per 100 ml Total Coliform and E. Coli (indicator of fecal contamination) were tested for in all of the routine samples. There were no E. Coli bacteria detected in any of the potable water samples. With respect to Total Coliform, seven (7) sample were found to contain Total Coliform but at no time didd the percentage of samples tested positive for Total Coliform exceed the 10% stipulated in the B.C. Drinking Water Protection Regulations (see Figure 7 below). Furthermore, none of the seven samples that tested positive for Total Coliforms was greater than 10. Any sample withh greater than 1 Total Coliform would result in resampling. Any sample with greater than 10 Total Coliforms would result in a follow up with FHA and immediate flushing of applicable water mains and re sampling. Any potable water sample result showing bacteriological criteria exceedancee is immediately reported to the FHA and mutually acceptable corrective actions such as, but not limited to, line flushing and re sampling would be undertaken. 2013

24 22 City of Burnaby Annual Drinking Water Quality Report WATER UTILITY INCIDENT RESPONSE PLAN In the event of major emergencies or disasters, the Engineering Department is responsible for restoring/maintaining water utility operations inn order to ensure that water quality, quantities and pressures are sufficient for the distribution of drinking water and effective fire fighting. The Water Utility Incident Response Plan iss the Engineering Department s action plan to ensure compliance to the legislated requirements under the BC Drinking Water Protection Act and Regulation. Should water utility service be diminished by an emergency or disaster this plan will assist in reducing the impact and ensuring orderly response. CONCLUSION The City of Burnaby in partnership with Metro Vancouver consistently deliver clean, safe and aesthetically pleasing drinking water to the residents,, businesses and visitorss in Burnaby. In 2013, the physical, chemical and bacteriological characteristics off the water continues to be of high quality and in compliance with applicable regulations and guidelines. 2013

25 23 City of Burnaby Annual Drinking Water Quality Report A PUBLIC HEALTH MESSAGE FROM THE FRASER HEALTH AUTHORITY As per standard recommended water practices, Water from taps that are not used for several hours is good for washing or watering plantss but not for drinking or cooking, as it may contain elevated levels of lead or copper. Run thee water for at least one minute, or until the water is cold before using it for drinking or cooking. For the same reason never use water from hot taps for drinking or cooking. As per the request from the Fraser Health Authority the HealthlinkBC File #56 HealthlinkBC File #56 Persons with Compromised or Weakened Immune Systems, has been attached to the Annual Drinking Water Quality Report. 2013

26 Number 56 August 2009 Drinking Water and Those with Weakened Immune Systems Some people with very weak immune systems may be at higher risk of water-borne infections. This file provides information about how to help prevent water-borne infections. People who have significantly weakened immune systems and who are at higher risk of certain water-borne diseases include: People with HIV infection who have a CD4+ count of < 100 cells/mm 3. People with hematological malignancies (lymphoma or leukemia) who are being actively treated or have been in remission and off treatment for less than 1 year. Hematopoietic stem cell transplant recipients. People born with diseases that severely affect their immune systems. Some people with weakened immune systems, such as those with certain types of cancers or taking certain medications, may not be at higher risk of severe water-borne diseases. These people do not need to take extra precautions with their drinking water. Ask your doctor or specialist how weak your immune system is, and whether you need to take extra precautions. Diseases from drinking water Drinking water can contain different organisms, including bacteria, viruses and parasites, which can cause disease. These organisms can exist in the source water such as lake water and survive through treatment, or they can enter the water supply in the distribution system. Well water can be contaminated if the well is not built properly or if it draws on water from the surface of the ground, such as shallow wells or wells drilled in fractured rock. Surface water, such as rivers, lakes and streams, can also contain disease-causing organisms from animal feces. If you have a weak immune system, you should not drink water from surface sources or wells potentially contaminated by surface water (for example, dug wells), unless the water has been treated to remove or inactivate at least 99.9% of parasites (protozoa), 99.99% of viruses and 100% of harmful bacteria. Most community water systems in B.C. have effective treatment, such as disinfection or chlorination, against bacteria and viruses. However, in many cases, treatment may not provide a 99.9% reduction in infectious parasites. Furthermore, some water systems and many private supplies have no treatment at all. If the water you drink has not been disinfected, please refer to HealthLink BC File #49b How to Disinfect Drinking Water. To further treat drinking water that has been disinfected, consider the methods listed below. Options for water treatment Boiling: If your water supply is disinfected you need only bring the water to a full boil to inactivate any Cryptosporidium parasites - a major concern for immunocompromised people, as there is no medical treatment for this parasite. If the water is not yet disinfected, it s recommended you bring water to a full boil for at least one minute as the best way to kill or inactivate bacteria, viruses and parasites.

27 At elevations over 2,000 meters [6,500 feet], you should boil water for at least two minutes to disinfect it. In this situation, you should not drink or use tap water to brush your teeth, rinse your mouth, mix drinks or make ice cubes without boiling it first. If you are preparing infant formula, please see HealthLink BC File #69b Formula Feeding Your Baby: Safely Preparing and Storing Formula. Please note that boiling water will get rid of viruses, bacteria and parasites but not chemicals which may be found in the water. For more information, please contact the environmental health officer or drinking water officer at your nearest public health unit. Filters: If you plan to install a drinking water filter in your home, you will need a system labeled as "Absolute" 1 micron or smaller, and labeled as meeting ANSI/NSF International Standard #53 for removal of parasites. These are not suitable for removing bacteria and viruses and should not be used unless the water supply is at least disinfected first. Jug-type filters, which sit in a jug and allow water to trickle through, and some tapmounted and built-in devices are not an appropriate solution. The jug filter models are not effective in removing many diseasecausing organisms. Reverse Osmosis (RO): RO is effective against all disease-causing organisms and many chemical contaminants. Unless it has a high capacity, it will only produce small amounts of water and waste a large volume. Speak to a water treatment specialist to see if this is the best option for you. treatment units should meet NSF Standard #55A. Bottled water If you do not want to drink water from the tap, you may also choose to buy bottled water that has been treated adequately. Most bottled water in B.C. has had RO treatment, but not all has been treated. You should check with the water bottler to find out what treatment it has had. You can still use tap water for cooking as long as you boil it. You can use bottled water treated by reverse osmosis for drinking, brushing teeth, making ice cubes and for recipes where water is used but not boiled such as cold soups or salad dressings. For more information, including the level of treatment in your local water system, please contact your drinking water purveyor or supplier or the local environmental health officer or drinking water officer. Please also see the following HealthLink BC Files. #49a Water-borne Diseases in BC #49b How to Disinfect Drinking Water For more HealthLink BC File topics, visit or your local public health unit. Click on or call for non-emergency health information and services in B.C. For deaf and hearing-impaired assistance, call in B.C. Translation services are available in more than 130 languages on request. Ultraviolet (UV) Treatment: UV light will kill many disease-causing organisms, and it is effective against almost all parasites. UV will not kill some bacterial spores and some viruses, so it should not be used unless the water supply is at least disinfected. UV

119 Section E 1.2 To: From: Utilities Committee Larry Chow, Program Manager Quality Control Date: April 1, 2014 Meeting Date: May 13, 2014 Subject: 2013 GVWD Quality Control Annual Report RECOMMENDATION That the GVWD Board receive for information the report titled 2013 GVWD Quality Control Annual Report, dated April 1, PURPOSE To provide the Board with a summary of the 2013 GVWD Quality Control Annual Report on drinking water quality. BACKGROUND Each year Metro Vancouver is required, under the Provincial Drinking Water Protection Regulation, to produce an annual report on drinking water quality. The annual report is also a requirement of the Drinking Water Management Plan. The annual report provides the key results and findings associated with Metro Vancouver s program of continuous monitoring and assessment of drinking water quality in the region. The annual report also provides an assessment of drinking water quality relative to the existing drinking water standards and guidelines and highlights any unusual occurrences. Municipal monitoring results are also discussed in the Annual Report where relevant. The annual report will be sent to the Chief Medical Health Officers of the Vancouver Coastal and Fraser Health Authorities. Additionally, the Annual Report will be made accessible to the public through public libraries in the region, including Metro Vancouver s library and Information Centre and will be posted on Metro Vancouver s website. DISCUSSION A summary of the main items relevant to water quality during 2013 follows: a) Source Water Quality i) In 2013, the turbidity levels associated with Metro Vancouver s delivered drinking water easily met the requirements of the Guidelines for Canadian Drinking Water Quality (GCDWQ). ii) The Capilano water supply was out of service for much of 2013 due to high or fluctuating turbidity levels (Capilano was in service for 117 days during the year). Capilano water supply was out of service from the beginning of the year to early May. On August 30 th the turbidity of the Capilano source started to increase and the source was removed from service. It remained out of service for the rest of the year. During Greater Vancouver Water District - 14

120 the period that this source was in service in 2013, the turbidity of Capilano water did not exceed 1 nephelometric turbidity unit (NTU). iii) The Seymour water supply was in service for the entire year and source turbidity was generally less than 1 NTU throughout the year except during the heavy rainfall event in early September that resulted in source water turbidity peaking at 5 NTU. iv) The Coquitlam water supply was in service for the entire year. The average daily turbidity of the Coquitlam source (not filtered) slightly exceeded 1 NTU for one day. v) The bacteriological quality of the three source waters was good in All three sources easily met the bacteriological requirements outlined in the GCDWQ. vi) Results of the analysis of the source water for herbicides, pesticides, volatile organic compounds and radionuclides were all below the recommended limits for these substances listed in the GCDWQ. b) Water Treatment i) There was no loss of primary disinfection of the Capilano and Coquitlam sources in ii) The Seymour Capilano Filtration Plant (SCFP) provided full filtration of the Seymour source. The associated disinfection process included ultra violet light treatment and the addition of chlorine. SCFP performance, as measured by the quality of the delivered water, continued to be good in The daily average turbidity leaving the clearwells and entering the GVWD transmission system was less than 0.08 NTU. The results from the twenty four individual filter effluent turbidity readings easily met the turbidity requirements of the GCDWQ. Filtration consistently removed iron, colour and organics from the Seymour source water. iii) Levels of total aluminum in the filtered water were consistently below the GCDWQ operational guideline value of 0.2 mg/l for direct filtration plants using aluminiumbased coagulants. The maximum value for 2013 was less than 0.1 mg/l. iv) The secondary disinfection facilities operated as required. The secondary disinfection stations that receive filtered water were seldom required to boost chlorine as the chlorine demand of filtered water is significantly lower than that of unfiltered water. c) Distribution System Water Quality i) Bacteriological water quality was good in the GVWD reservoirs and transmission mains. There was no E.coli detected in any of the samples collected in ii) Bacteriological water quality was good in the distribution systems of the member municipalities. Of approximately 21,000 municipal samples collected for testing in 2013 a high percentage (99.9%) were free of coliforms which was similar to 2012 (99.9%). E.coli was not detected in any of the samples tested. Greater Vancouver Water District - 15

121 iii) The running averages of the trihalomethane group of chlorine disinfection by products detected in the delivered water in the GVWD and municipal systems were well below the Maximum Acceptable Concentration (MAC) in the GCDWQ of 100µg/L (0.1 mg/l). The running averages for the haloacetic acid group of chlorine disinfection by products were below the Canadian Guideline MAC of 80µg/L (0.08 mg/l), with one exception where a single result from one sample location caused the guideline to be exceeded for that location. FINANCIAL IMPLICATIONS Not applicable. ALTERNATIVES No alternatives presented; this is an information report. SUMMARY / CONCLUSION As illustrated by the 2013 GVWD Quality Control Annual Report, Metro Vancouver s water quality monitoring program continues to fulfill its role of confirming that the water quality barriers the GVWD has in place including watershed protection, water treatment and ongoing operation of the water system to maintain water quality, are working effectively and that the drinking water provided by the GVWD to its customers consistently met or exceeded water quality standards and guidelines in Greater Vancouver Water District - 16

128 1 EXECUTIVE SUMMARY Source Water Quality o o o o o o In 2013, the turbidity levels of the delivered water easily met the requirements of the Guidelines for Canadian Drinking Water Quality (GCDWQ). The Capilano supply was out of service for much of 2013 due to high or unstable turbidity (Capilano was in service for 117 days during the year). Capilano started the year out of service and remained that way until early May. On August 30 th, the turbidity of Capilano started to increase and the source was removed from service and remained out of service for the rest of the year. While this source was in service in 2013, the turbidity of Capilano water did not exceed 1 NTU. The Seymour supply was in service for the entire year and was treated at the Seymour Capilano Filtration Plant (SCFP). Water entering the GVWD transmission system from the SCFP had turbidity of mostly <0.1 nephelometric turbidity unit (NTU) for the entire year. For water entering the SCFP, turbidity was generally less than 1 NTU throughout the year except during the heavy rainfall event in early September that resulted in source water turbidity peaking at 5 NTUs. Even with the level of turbidity in the source water reaching almost 5 NTU, the turbidity levels of filtered Seymour water were mostly less than 0.1 NTU. The Coquitlam supply was in service for the entire year. The average daily turbidity of the Coquitlam source (not filtered) was minimally over 1 NTU for one day in March. Water treatment levels were increased during this period in accordance with operating protocols. The bacteriological quality of the three source waters was good in All three sources easily met the bacteriological requirements for avoiding filtration outlined in the Turbidity section of the Guidelines for Canadian Drinking Water Quality. Results of the analysis of the source water for herbicides, pesticides, and volatile organic compounds and radionuclides were all found to be below the recommended limits for these substances listed in the Guidelines for Canadian Drinking Water Quality. Water Treatment o There was no loss of primary disinfection in The secondary disinfection facilities operated as required. o o o o o The Seymour-Capilano Filtration Plant provided full filtration and the plant performance, as measured by the quality of the delivered water, was good in The daily average turbidity of water leaving the clearwells to enter the GVWD transmission system was less than 0.08 NTU in Turbidity levels for individual filters easily met the turbidity requirements of the GCDWQ. The secondary disinfection stations that receive filtered water were seldom required to boost chlorine as a result of the reduced chlorine demand of filtered water. Filtration consistently removed iron, colour and organics from Seymour source water. Levels of total aluminum in filtered water were consistently below the Guidelines for Canadian Drinking Water Quality operational guideline value of 0.2 mg/l for direct filtration plants using aluminum-based coagulants. The maximum value for 2013 was 0.09 mg/l

129 Distribution System Water Quality o o o o Bacteriological water quality was good in the GVWD transmission mains. No samples were positive for E. coli in Bacteriological water quality was good in the GVWD transmission reservoirs. There was no E. coli detected in any of the samples collected. Bacteriological water quality was good in the distribution systems of the member municipalities. Of approximately 21,000 municipal samples collected for testing in 2013 a high percentage (99.9%) were free of total coliforms which was similar to 2012 (99.9%). In 2013, no E. coli was detected. The running averages of the trihalomethane group of chlorine disinfection by-products detected in the delivered water in the GVWD and municipal systems were well below the Maximum Acceptable Concentration (MAC) in the GCDWQ of 100μg/L (0.1 mg/l). The running averages for the haloacetic acid group of chlorine disinfection by-products were below the Canadian Guideline MAC of 80μg/L (0.08 mg/l), with one exception where a single result from one sample location caused the guideline to be exceeded for that location

132 4 SOURCE WATER QUALITY The first barrier in place to protect the quality of the drinking water supply is the protection of the watershed to ensure the best quality source water. Source water monitoring provides ongoing confirmation that the barrier is effective, identifies seasonal changes and provides the monitoring information necessary to determine the level of water treatment required. Regular monitoring of the water sources is also a requirement of the Water Quality Monitoring and Reporting Plan (WQMRP). 4.1 BACTERIOLOGICAL QUALITY OF THE SOURCE WATER The bacteriological quality of the source water is an important indicator of the degree of contamination, and the treatment required to ensure a safe water supply. The Canadian Guideline for Turbidity (October 2003) stipulates bacteriological quality of the source water in its criteria for avoiding filtration as follows: Prior to the point where the disinfectant is applied, the number of Escherichia coli (E. coli) bacteria in the source water can exceed 20/100 ml (or, if E. coli data are not available, the number of total coliform bacteria can exceed 100/100 ml) in not more than 10% of the weekly samples from the previous 6 months. Table 1 below summarizes E. coli data from August 2012 to December 2013 for all three Metro Vancouver water sources and indicates that levels of E. coli for all three sources were well below the 10% limit in the turbidity guideline. Table 1: Percent of samples in six months (current month plus five previous months) where number of E. coli. /100 ml exceeded 20 Capilano Seymour Coquitlam Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Figure 1 shows the results of the analysis of the source water from 2009 to 2013 at all three intakes compared to the limits for source water bacterial levels in the 2003 turbidity guideline. As in the previous years, all three sources easily met the limit of not more than 10% exceeding 20 E. coli/100 ml. As was also the case in previous years, samples collected at the intakes in the fall and winter had the highest E. coli levels. These E. coli can be traced back to high levels at the main tributaries of the supply lakes and a first flush phenomenon after a period of dry weather

Outbreaks of Giardiasis occurred in a number of locations in B.C. and Washington State in the late 1980s, and the District has been monitoring raw water and animal droppings for Giardia since Since 1992, Metro Vancouver has participated in a project with the Enhanced Water Testing Laboratory, University of British Columbia, to gather more information about the number and nature of the cysts found in the Greater Vancouver water supplies. The project involves collecting samples from the Capilano and Coquitlam supplies upstream of disinfection. Routine monitoring of Seymour source water was discontinued in 2011 because water treatment at the SCFP meets the disinfection requirements for both Giardia and Cryptosporidium in the GCDWQ. At the SCFP, monitoring for Giardia and Cryptosporidium has focused on the recycled water returning to the head of the plant and confirmed that the procedures in place effectively control the levels of Giardia and Cryptosporidium in the recycled wash water from the filters. The results of the 2013 testing program are contained in the Report to the Greater Vancouver Regional District - Giardia and Cryptosporidium Study January - December, 2013 which was prepared by the Enhanced Water Laboratory and can be found in Appendix 3. The numbers of Giardia and Cryptosporidium cysts and oocysts detected in 2013 compared to results from previous years again fluctuated with no discernible pattern. In summary, 6 of 12 (50%) samples collected at Capilano and 3 of 13 (23%) at Coquitlam were positive for Giardia (Table 2). As discussed in the previous paragraph Seymour samples for 2013 are all process control samples and not Seymour source water as they were previous to 2011 (shown as N/A in the table)

134 Table 2: Percentage of Water Samples Positive for Giardia Capilano Seymour N/A N/A N/A Coquitlam One of 12 (9%) samples collected at Capilano were positive for Cryptosporidium, 1 of 13 (9%) were positive at Coquitlam. As discussed in the section on Giardia above, Seymour samples for 2013 are all process control samples and not Seymour source water as they were previous to 2011 (shown as N/A in the table).. Table 3 shows a comparison of Cryptosporidium levels in our water supplies for Capilano and Coquitlam from 2004 through 2013 and Seymour source water from 2004 to Table 3: Percentage of Water Samples Positive for Cryptosporidium Capilano Seymour N/A N/A N/A Coquitlam Year to year fluctuations are best demonstrated for Giardia by Capilano (28% positive in 2004 and 50% positive in 2013) and for Cryptosporidium by Coquitlam (60% positive in 2004 and 8% positive in 2013). There has always been considerable variation in the results from year to year. 4.3 TURBIDITY MV water sources have historically been susceptible to turbidity upsets due to high runoff from storms which can cause slides and stream scouring in the watersheds or from re-suspension of sediment from the edges of the lakes during periods of low water levels. Health Canada published a turbidity guideline in 2003 which recommends filtration for all surface water supplies but the guideline has a provision for exemption from this requirement for filtration if a source meets certain criteria including a turbidity provision. The 2003 guideline allows a utility to avoid filtration if the turbidity does not exceed the requirements (see next paragraph) and that a number of other provisions including source water protection and water treatment requirements are in place. Historically the turbidity levels on both the Capilano and Seymour sources would not meet these criteria therefore plans were developed to filter both supplies. Filtration of 100% of the Seymour supply began on January 15, 2010 and filtration of the Capilano supply will begin once the twin tunnel project is complete. Section 3.3 of the 2003 Guidelines for Canadian Drinking Water Quality Supporting Documentation titled Turbidity, Criteria for Exclusion of Filtration in Waterworks Systems contains the following requirement for the turbidity: Average daily source water turbidity levels measured at equal intervals (at least every 4 hours), immediately prior to where the disinfectant is applied, are around 1.0 NTU but do not exceed 5.0 NTU for more than 2 days in a 12-month period. In the GVWD, the turbidity of source water is monitored upstream of disinfection using an in-line turbidimeter. The data is captured as 10 minute averages and is stored in the Supervisory Control and Data Acquisition (SCADA) system. This 10-minute average data points (144/day) have been averaged to produce a daily average turbidity which is shown in Figure

135 Turbidity (NTU) Until the Capilano supply is filtered, MV turbidity response protocol focuses on minimizing the amount of water with turbidity greater than 1 NTU entering the system. Following this protocol, the Capilano source was taken out of service in the August 30th, 2013 and stayed out of service for the remainder of the year. As a result of these actions, no Capilano source water was delivered that had a turbidity that exceeded 1 NTU at anytime during Figure 2: 2013 Average Daily Turbidity of Source Water (from In-Line Readings) Capilano Source Out of Service (OOS): Jan 1 - May 3; Aug 30 - Dec Jan 20-Feb 11-Apr 31-May 20-Jul 8-Sep 28-Oct 17-Dec Capilano Coquitlam Seymour Table 4: Delivered Water Turbidity Summaries (Non Filtered Sources) 2013 Source Percent of Days with Average Daily Turbidity >1 NTU Number of Days with Average Daily Turbidity >5 NTU Capilano * 0 0 Seymour** N/A N/A Coquitlam** *Capilano was in service for 117 days in **Seymour was in service for all of 2013, 100% of Seymour water was filtered so these source water criteria don t apply to the delivered water. *** Coquitlam was in service for all of

136 4.4 CHEMISTRY Chemical and Physical Characteristics of the Source Water The chemical and physical characteristics of the Metro Vancouver source water are summarized in Appendix 1 of this report; detailed analytical results are provided in Volume II. The results from the chemical and physical analyses of the source water in 2013 were similar to those for other years except that the total iron levels of Seymour source water did not exceed the GCDWQ aesthetic limit of 300 µg/l in Herbicides, Pesticides, Volatile Organic Compounds, Radioactivity, and Uranium Analyses of the source water for a variety of organic compounds including all the compounds with Maximum Acceptable Concentrations (MACs) in the Guidelines for Canadian Drinking Water Quality is usually carried out on annual basis in accordance with the WQMRP. The results are contained in Appendix 2 of this report and in Volume II of the QC Annual Report. The only constituents present in levels above the detection limits were gross alpha and gross beta radioactivity. These levels are indicative of erosion of natural deposits and are well below the applicable Canadian Guideline health based limits, meaning the contribution to total radiation exposure from drinking water in this area is small, and typical of most areas

137 5 QUALITY CONTROL ASSESSMENT OF WATER TREATMENT Water treatment is the second barrier (after source protection) used to assure the quality of the water supply. 5.1 PRIMARY DISINFECTION OF CAPILANO AND COQUITLAM SOURCES Primary disinfection is the treatment of the source water to destroy disease-causing or pathogenic microorganisms. Metro Vancouver uses the strong oxidizing agents, chlorine and ozone, for primary disinfection of the Capilano and Coquitlam sources, respectively. The amount of these chemicals that is required for disinfection is based on a number of factors, including the temperature and ph of the water. Disinfection also requires contact time of the oxidant with water to provide adequate disinfection. Construction of the Coquitlam UV Disinfection Plant commenced in spring 2011 and this plant is expected to be brought into full service during the first half of The Coquitlam UV facility will enhance the primary disinfection capability at Coquitlam to include treatment for Cryptosporidium as well as provide treatment for Giardia in addition to that provided by the ozonation process. Precommissioning work continued in 2013; this work resulted in some interruptions of the processes. Table 5 provides an assessment of the disinfection process at these water sources. Table 5: Performance of Primary Disinfection Facilities Facility Performance Discussion Capilano Chlorination Coquitlam Ozonation Coquitlam Chlorination The average of residual chlorine concentration was 1.20 mg/l 100% while in operation Goal is Log 10 3 Giardia inactivation (99.9% Giardia removal). Log 10 > 3 Giardia inactivation achieved when ozonation worked in 2013 except 120 minutes on May 09 due to a flow increase. Time Log 10 < 3 Giardia = 120 min Total hours of no ozonation during operating time was 13.4 hrs = 0.17% This facility provides secondary disinfection most of the time but during ozone outages it is used for primary disinfection. The chlorine residual was > 1.0 mg/l 100% of the time when the facility was used for primary disinfection. The Capilano facility was in service for 117 days (May 4 to August 30). Reasons for shut down of the ozone plant in 2013 are as follows. Planned shutdown ( hrs) -March 13 to May 3 (UV tie-ins work) -July 4(LOX crossover leak repair) -August 27(BC Hydro fuse replacement) Loss of ozonation (total 13.4 hrs): -Power failure 59 min -Instrument failure 746 min When Coquitlam Chlorination was used as primary disinfection facility, Cl 2 residual was increased by 0.2 mg/l to partially offset the loss of ozonation

138 Apparent Colour (ACU) 5.2 SEYMOUR-CAPILANO FILTRATION PLANT The Seymour-Capilano Filtration Plant (SCFP) is a chemically assisted direct filtration plant which uses alum or poly aluminum chloride (PACl) as a coagulant with polymers to improve particle removal. These substances help aggregate particles to form a visible floc. The flocculated particles are removed by passing this water through a filter medium of anthracite and sand. The result is the production of filtered water which is then exposed to UV light as the water leaves the filter. Post UV Filtered water has sodium hypochlorite (chlorine) and lime added before the water enters the Clearwells. The West and East Clearwells are large water storage reservoirs that store and allow controlled passage of water with some mixing or blending of the lime and chlorine that have been added. Clearwells allow sufficient retention or contact time with chlorine to provide any further disinfection required after filtration and UV. Carbon dioxide in solution may be added to trim ph. After stabilization of the filtered water in the Clearwells, the finished water is ready to enter the transmission system at the Seymour Treated Water Valve Chamber. SCFP has been operational since December of 2009 and the quality of the water produced has been excellent, improving year after year. As a result of treatment now in place on the Seymour water source there have been a number of changes in the characteristics of the delivered water. Some of these changes are visible, some not. The most obvious visible change in the water is the decrease in colour and increase in the clarity. There is a total loss of the brown hue that is characteristic of Seymour water before filtration. This change in colour is because the natural components that cause the brown water are removed in the filtration process. Suspended particles in water that cause light to scatter (turbidity) are also removed. The end product is water that is very clear. Due to the purity of the water it may have a slight bluish colour. Figure 3: Apparent Colour Levels Before and After Filtration Delivered Source Figure 3 is a graph of the apparent colour of Seymour filtered water and Seymour source water for In the summer of 2013 the apparent colour of the Seymour source water that was feeding the filtration plant looked brown and exceeded 25 ACU while, with the removal of its natural brown colours, the filtered water that was delivered to the public was never greater than 3 ACU

139 Figure 4: Average Daily Turbidity Levels Before and After Filtration 2013 Figure 4 compares turbidity of source water that feeds the filtration plant to the turbidity level of the finished filtered water for Without filtration the Seymour source would have delivered water with an average daily turbidity greater than 1 NTU for 35 days and a maximum daily average of 1.7 NTU. With filtration, the maximum average daily turbidity of the delivered water was 0.09 NTU and the average was 0.05 NTU. Removal of turbidity in the source water improves the appearance of the water but it also has the benefit of removing certain types of pathogenic microorganisms that may be present in source water. At a minimum, properly run direct filtration plants such as SCFP will remove up to 2.5 log (one log is a 90% reduction) of Cryptosporidium and Giardia plus 1 log of viruses. To ensure this removal it is critical that the performance of each filter, determined by the turbidity of its effluent, is monitored on a continuous basis. The GCDWQ (2003) states, Where possible, filtration systems should be designed and operated to reduce turbidity levels as low as possible with a treated water turbidity target of less than 0.1 NTU at all times. If <0.1 NTU is not achievable, the treated water turbidity levels from individual filters (Individual Filter Effluent IFE): for chemically-assisted filtration, shall be less than or equal to 0.3 NTU in at least 95% of the measurements made, or at least 95% of the time for each calendar month, and shall not exceed 1.0 NTU at any time. Ideally the turbidity from each individual filter would never exceed 0.1 NTU however, there are rare occurrences of turbidity readings that exceed the ideal level. The turbidity performance of all twenty-four filters was measured by examining the percent of time that the turbidity of each individual filter effluent (IFE) was less than the turbidity goal of 1.0, 0.3 and 0.08 NTU (Table 6). Turbidity data presented in Table 6 measures the percentage of time that turbidity met the guideline requirements was chosen as it is achievable for filters under normal operating conditions

140 Table 6: Monthly Filter Effluent Turbidity Summary Month Incident of IFE Turbidity Greater than 1.0 NTU None allowed Percent of Time IFE Turbidity Less than 0.3 NTU 95% allowed Percent of Time IFE Turbidity Less than 0.08 NTU Target 100% Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec In 2013 there were no IFE turbidity readings greater than 1 NTU. Under normal operating conditions two rows of lamps operating at 75% power provides enough UV to meet the dosage requirement for 2 log reduction of cyrptosporidium. A water treatment facility such as SCFP should be able to produce a filter effluent that is less than 0.1 NTU. Under normal operating conditions the turbidity of the filtered water at SCFP is less than 0.08 NTU and this level of turbidity is a better benchmark measuring the performance of the plant than 0.3 NTU. The effluent from each filter is treated with UV as the water exits the filter. UV treatment is effective in altering the DNA structure of Cryptosporidium and Giardia thus rendering oocysts and cysts of these parasites non-infectious. Other disinfectants, especially chlorine, are ineffective against Cryptosporidia oocysts. In the event of a breakthrough of Cryptosporidia oocysts, especially at the end of a filter run, UV light is present to render any potentially present parasites non-infectious. Oocysts are not able to proliferate inside the intestines of human hosts to cause illness after a sufficient dose of UV light. It should be noted that many viable oocysts are required to infect a healthy human host. The target dose for UV to achieve 2 Log (99%) of Cryptosporidium and Giardia inactivation is 21mJ/cm

141 Table 7 summarizes the performance of the UV system in Table 7: Percent of Time UV Dosage Met Requirements Month Percent of Time UV 21 mj/cm 2 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec SECONDARY DISINFECTION There are eight rechlorination stations operated by Metro Vancouver. The purpose of these stations is to increase the chlorine residual in the water flowing through the stations to meet a target residual based on a number of factors including source water turbidity, the amount of bacterial regrowth detected in the municipal distribution system samples and the chlorine demand in the water. Prior to 2010, under usual water conditions, the target average residual was 1 mg/l leaving Rice Lake (location near SCFP). With the arrival of filtered water in 2010, the rate of chlorine decay in the (filtered) water has been reduced to such a low level that the amount of chlorine required to maintain a residual in the distribution system is much lower. This has allowed reduction of the target chlorine dose leaving the secondary facilities (receiving filtered water) to between 0.6 to 0.8 mg/l. The rechlorination facilities receiving the filtered water rarely have an incoming chlorine residual low enough to require boosting thus the amount of sodium hypochlorite being used at secondary chlorine facilities has been considerably reduced. Consequently many secondary chlorination stations are running in stand-by mode when supplied with filtered Seymour water. When supplied with unfiltered Capilano and Coquitlam water, the secondary stations activate frequently to boost chlorine

When gaseous chlorine (in cylinders of pressurized liquid chlorine) is added to water, it quickly hydrolyzes to form hypochlorous acid, hydrogen and chloride ions. This reaction results in a drop in ph and alkalinity with subsequent increase in chloride level of water. These changes increase the corrosiveness of already corrosive water (due to natural low ph, low alkalinity and high dissolved oxygen). Before 1998, the delivered water from all three sources had a ph lower than the aesthetic limit of the GCDWQ of ph 6.5. As part of the upgrade of the water treatment of the Seymour source water, a corrosion control facility using soda ash (sodium carbonate) was put into service at Rice Lake in A similar facility was added at Coquitlam in 2000 simultaneously with the ozonation facility. Since early 2010 corrosion control for the Seymour source was moved to the SCFP. In the SCFP process, filtered water receives a lime / water slurry to raise its ph and boost its alkalinity before it enters the Clearwells; it is finally adjusted with the addition of carbon dioxide gas (CO 2 ). The ph of water from Seymour and Coquitlam is consistently above ph 6.5 and meets the aesthetic objective

143 In October of 2003, the source of chlorine for disinfection at Capilano was switched from gaseous chlorine to liquid sodium hypochlorite. When sodium hypochlorite (bleach) is used as the source of chlorine for disinfection, there is no drop in ph because sodium hypochlorite is alkaline (there is actually a slight increase in ph). Since the switch the treated water has a ph greater than or equal to ph 6.5 most of the time. Starting in 2014, Capilano water will be treated at the SCFP and will undergo the lime/co 2 treatment process for ph and alkalinity adjustment.. With the addition of the corrosion control facilities on the Seymour and Coquitlam supplies and the switch from gaseous chlorination to sodium hypochlorite at Capilano, there has been a decrease in corrosion related calls from the public. Table 9: Performance of Corrosion Control Facilities Facility Performance Discussion Seymour - SCFP Corrosion Control Coquitlam - Corrosion Control Excellent Excellent From May 4 22 chambers 2 & 3 and the West chamber of the clearwell were bypassed. During this period the CO 2 system was not operational, lime was still added but at a lower dosage. Despite this the ph was maintained in the range recommended in the GCDWC at all times The ph was <6.5 for 13.2 hours (0.15% of the time) in 2013 due to soda ash system maintenance in August and commissioning in December. The chemical and physical characteristics of the Metro Vancouver treated water are summarized in Appendix 1 of this report, detailed analytical results are provided in Volume II

144 6 DISTRIBUTION SYSTEM WATER QUALITY Schedule A of the BC Drinking Water Protection Regulation contains standards for the bacteriological quality of potable water in the province. There are three components of this standard that apply to large utilities such as the GVWD and its members. Part 1: Part 2: Part 3: no sample should be positive for E. coli not more than 10% of the samples in a 30 day period should be positive for total coliform bacteria when more than 1 sample is collected no sample should contain more than 10 total coliform bacteria per 100 ml The BC Regulation does not contain any water standards other than the three limits for E. coli and total coliform bacteria. Information on the significance of the detection of these organisms can be found in the Guidelines for Canadian Drinking Water Quality - Supporting Documents. E. coli is a member of the total coliform group of bacteria and is the only member that is found exclusively in the faeces of humans and other animals. Its presence in water indicates not only recent faecal contamination of the water but also the possible presence of intestinal disease-causing bacteria, viruses, and protozoa. The presence of total coliform bacteria in water in the distribution system (but not in water leaving the treatment plant) indicates that the distribution system may be vulnerable to contamination or may simply be experiencing bacterial regrowth. To summarize, the detection of an E. coli bacteria in a sample of treated water is an indication of a potentially serious risk. The detection of total coliform bacteria may indicate intrusion into the system or it may indicate that these bacteria are growing in the distribution system itself (regrowth). The number of E. coli detected in both the GVWD and the municipal drinking water samples is typically very low out of approximately 29,000 samples collected from the GVWD and municipal systems analyzed in 2013 no samples were positive for E. coli. The detection of an E. coli triggers a protocol which involves immediate notification of health and municipal officials, re-sampling and a thorough investigation into the possible causes. Only 32 of the approximately 29,000 samples collected from the municipal distribution systems tested positive for total coliforms in The majority of the coliforms in the municipal system appeared in the warm water months (65% in August and September) and at sites with no measurable free chlorine residual. The most likely source of these organisms can be attributed to regrowth. The one fact that should be emphasized is that 99.9% of the samples in 2013 had no coliforms present a good indicator of effective water treatment and good distribution water quality. 6.1 MICROBIOLOGICAL WATER QUALITY IN THE GVWD SYSTEM GVWD Water Mains Over 4800 GVWD water main samples were collected and tested for the presence of indicator bacteria. The compliance of monitoring results from GVWD transmission mains with the criteria in the BC Drinking Water Protection Regulation is shown below in Figure 5. There were another 1300 samples collected from the chlorine evaluation stations and the 10-minute chlorine line at each source and these samples are not included in the calculations for compliance monitoring

Of the more than 4800 samples processed, only 3 samples was positive for total coliforms and no samples were positive for E. coli bacteria GVWD Reservoirs In 2013, over 2,400 samples were collected from the 21 reservoirs and tanks that are located throughout the GVWD water system. Only 2 samples were positive for total coliforms. No sample from a reservoir was positive for E. coli. The compliance of monitoring results from GVWD reservoirs with the criteria in the BC Drinking Water Protection Regulation is shown below in Figure

Table 10 below provides an overview of the status of the GVWD reservoirs. During certain times of the year, it is not possible to cycle reservoirs as much as would be desired due to operational constraints. Despite these constraints, water quality as determined by coliform bacteria was satisfactory in all reservoirs

148 Percent of Samples 6.2 MICROBIOLOGICAL WATER QUALITY IN MUNICIPAL SYSTEMS The percent of samples per month in samples collected in the municipalities positive for total coliform bacteria for the past five years is shown in Figure 7: Figure 7: Percent of Samples per Month Positive for Total Coliform Bacteria 2009 to Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec The percentage of samples positive for total coliform bacteria in 2013 was about the same percentage for Schedule A of the BC Drinking Water Protection Regulation contains standards for the bacteriological quality of potable water in the province. There are three components of this standard that apply to municipalities: Part 1: Part 2: Part 3: no sample should be positive for E. coli not more than 10% of the samples in a 30 day period should be positive for total coliform bacteria when more than 1 sample is collected no sample should contain more than 10 total coliform bacteria per 100 ml For samples from municipal systems, this requirement was met in 2013 with the following exceptions: Part 3: One sample in July contained more than 10 total coliform bacteria. Two samples in August contained more than 10 total coliform bacteria. Table 11 shows the compliance of the samples collected in the member municipal distribution systems with the three bacteriological standards in the BC DWPR

Month Number that met Part 1 Number that met Part 2 Number that met Part 3 Number meeting all DWPR January February March April May June July August September October November December DISINFECTION BY-PRODUCTS IN THE DISTRIBUTION SYSTEM Section 5 discussed the changes in the characteristics of water before and after water treatment, such as the change in ph associated with chlorination and corrosion control. There are other changes that can occur as the water moves through, first, the GVWD and later the municipal infrastructure of pipes and reservoirs. One of the most significant changes is the production of chlorinated disinfection by-products (DBPs). DBP is a term used to describe a group of organic and inorganic compounds formed during water disinfection. Although the increase in chlorination levels improves the bacteriological quality of water, it can also result in the production of DBPs. Reactions between dissolved natural organic matter and chlorine lead to the formation of a variety of halogenated DBPs. There are two major groups of chlorinated DBPs: the total trihalomethanes (TTHMs) and the total haloacetic acids (THAA 5 ). Factors that affect DBP formation are: amount of chlorine added to water, reaction time, concentration and characteristics of dissolved organic materials (precursors), water temperature, and water ph. In general, DBPs continue to form as long as chlorine and reactive DBP precursors are present in the water. The maximum acceptable concentration (MAC) in the Canadian Guidelines for TTHMs is a locational yearly running average of 100 µg/l(0.1 mg/l) based on quarterly samples. Comparison of TTHM levels in 2009 and 2013 is shown in Figures 10 & 11 As in previous years, all TTHM results were below the MAC of 100 µg/l. The other group of disinfection by-products of interest is the Haloacetic Acid (THAA 5 ) group. In 2008 a MAC of 80 µg/l (0.08 mg/l) calculated as a locational yearly running average based on quarterly samples was approved in Canada. Comparison of THAA 5 levels for 2009 and 2013 is shown in Figures: 12 & 13. The levels of THAA 5 are usually higher than the levels of THMs. Unlike THMs, THAA 5 cannot be consistently related to water age because THAA5 are known to biodegrade over time when the disinfectant residual is low

150 Figure 8: Average Total Trihalomethane Levels in Municipal Samples 2009 Average TTHM=39 µg/l Figure 9: Average Total Trihalomethane Levels in Municipal Samples 2013 MAC for total THM values is 100 µg/l or (ppb)

151 Figure 10: Average Total Haloacetic Acid Levels in Municipal Samples 2009 Average THAA 5=54 µg/l Figure 11: Average Total Haloacetic Acid Levels in Municipal Samples 2013 Average THAA 5=34 µg/l MAC for total HAA 5 values is 80 µg/l or (ppb)

152 7 QUALITY CONTROL / QUALITY ASSURANCE In 1994, as required by a new Ministry of Health program, the Bacteriology Section of the Metro Vancouver laboratory received approval from the Provincial Medical Health Officer to perform bacteriological analysis of potable water as required in the B.C. Drinking Water Protection Regulation. An ongoing requirement of this approval is successful participation in the Clinical Microbiology Proficiency Testing (CMPT) program or its equivalent. The bacteriological laboratory has successfully participated in this program since Representatives of the Approval Committee for Bacteriology Laboratories carried out an inspection of the Metro Vancouver laboratory facilities at LCOC in the fall of 2012 as part of the process leading up to approval of the laboratory by the Provincial Health Officer which has been received. The next inspection is scheduled for In addition to the approval process discussed above, the Metro Vancouver Laboratory is accredited by the Canadian Association for Laboratory Accreditation (CALA) for the analysis of parameters for which the laboratory has requested certification. The laboratories have been inspected by representatives from CALA bi-annually since 1995, and most recently in 2013 as required by the accreditation process. Accreditation for the laboratory from the Standards Council of Canada was first received early in 1996 and continued until the middle of 2005, when accreditation was granted by CALA directly. Based on the 2013 inspection, CALA issued the latest accreditation for the Metro Vancouver Laboratory in February Details are available in the Quality Control office. The next CALA inspection will take place in the fall of

170 Report to Metro Vancouver Detection of Waterborne Giardia and Cryptosporidium Study January - December, 2013 PURPOSE To detect and quantify Giardia cysts and Cryptosporidium oocysts present in Filta-Max filters submitted regularly by Metro Vancouver from each of Capilano and Coquitlam reservoirs, as well as Recycled Clarified Water from Seymour-Capilano Filtration Plant (SCFP-RCW). INTRODUCTION Giardia cysts and Cryptosporidium oocysts are parasites that infect the intestinal tracts of a number of vertebrate animals. In humans, infection with Giardia lamblia or Cryptosporidium species can cause gastroenteritis. As the cyst and oocyst forms of Giardia and Cryptosporidium are resistant to chlorination, they are of great concern for drinking water purveyors (1-3). On behalf of Metro Vancouver, BC Public Health Microbiology and Reference Laboratories (BCPHMRL) is currently examining the source water of Capilano and Coquitlam reservoirs, as well as Recycled Clarified Water at the Seymour Capilano Filtration Plant for presence of Giardia cysts and Cryptosporidium oocysts. All sample collection, testing, analysis and reporting occurred on a monthly basis. METHODS The Environmental Microbiology Laboratory at BCPHMRL uses the United States Environmental Protection Agency (USEPA) Method 1623: Cryptosporidium and Giardia in Water by Filtration/IMS/FA (4) for the detection of oocysts and cysts in water. Method 1623 is a performance-based method applicable to the determination of Cryptosporidium and Giardia in aqueous matrices. It requires use of the filtration and immunomagnetic separation (IMS) process for concentration and purification of oocysts and cysts from sample material captured. An immunofluorescence assay is performed after the IMS procedure for identification and enumeration of oocysts and cysts, with confirmation using 4-6-diamidino-2-phenylindole (DAPI) staining and differential interference contrast (DIC) microscopy. Raw water samples were collected by Metro Vancouver staff at specific locations in each of the Metro Vancouver sampling sites. Water was filtered at designated sites in the reservoirs and filtration plant using IDEXX Filta-Max foam filter modules. Filters were transported to the BCPHMRL, by Metro Vancouver staff, where they were processed and analyzed.

171 RESULTS & DISCUSSIONS During 2013, a total of 37 Filta-Max filters were examined. These included: - 12 filters from the Capilano reservoir - 13 filters from the Coquitlam reservoir - 12 filters from SCFP-RCW Negative and positive controls were tested as required by the Environmental Microbiology Laboratory s Quality Assurance program. Summary of our findings are presented in Graphs 1-3 and Tables 1-5. An average of 50.0 and 46.2 L of raw water was filtered for Capilano and Coquitlam reservoir respectively. Average detection limit for Capilano and Coquitlam were <2.2 and <2.3 (oo)cysts per 100 L respectively. Average volume of water filtered and detection limit for SCFP-RCW were L and 0.5 (oo)cysts per 100 L respectively. Giardia cysts were detected more frequently than Cryptosporidium oocysts in all three Metro Vancouver sites. Capilano had the highest positive detection rate amongst all of the sampling sites with either Giardia cysts or Cryptosporidium oocysts being detected in 50.00% of filters. SCFP-RCW in contrast has the lowest incidence of Cryptosporidium oocyst (0.00%) and Giardia cysts (16.67%).
