3 1.0 INTRODUCTION The Drinking Water Protection Act sets out criteria for drinking water operators to ensure provision of safe drinking water. Provisions include required approval of system construction proposals, system operating permits, minimum water treatment standards and sampling, public notification procedures and operator certification. In 2003 the Province brought into effect the Drinking Water Protection Regulation (DWPR). Under these Regulations, a water purveyor is required to collect water samples and publish the results in accordance with the Schedule A (microbiological standards for E. coli, and total coliform) and Schedule B (frequency monitoring requirements) or as requested by the Medical Health Officer. In 2006, Metro Vancouver member municipalities agreed to follow the Water Quality Monitoring and Reporting Plan which incorporates the DWPR schedules and was approved by the Local Health Authority. The Guidelines for Canadian Drinking Water Quality are published by Health Canada on behalf of the Federal-Provincial-Territorial Committee on Drinking Water (CDW). The summary tables within this report are updated to reflect the latest quality guidelines published on-line at the Health Canada s Website: Under the Drinking Water Protection Act municipalities are required to obtain a permit to operate a water distribution system and produce an annual report summarizing the water quality. New Westminster obtained a permit to operate a water distribution system from the Health Authority in 1996, and has produced many previous Water Quality Monitoring Reports. Furthermore, water operations are classified via the Environmental Operations Certification Program (EOCP) and New Westminster has been classified as a Level 2 system. A copy of the classification certificate and the individual certificates of qualification are provided in Appendix A WATER QUALITY PROGRAM Currently the City is provided with water primarily from Metro Vancouver s Seymour and Coquitlam Reservoirs. Following the completion of the westerly transfer project it is also be possible to utilize the Capilano Reservoir as a source. Water quality is maintained by environmentally protecting each watershed and since 2000, primary disinfection has been achieved by the use of chlorine at Capilano and Seymour, and by means of ozone at Coquitlam. Improvements to drinking water quality are being undertaken by Metro Vancouver through the Drinking Water Treatment Program. In late 2009 Metro Vancouver added filtration to Seymour water. 3

4 2.1 DRINKING WATER TREATMENT PROGRAM The Drinking Water Treatment Program is a multi-phased program which has started with the commissioning of several secondary disinfection stations throughout the region. The major elements in this program are as follows: Secondary disinfection stations phase 1 - completed in 1998 Primary disinfection with ozone of Coquitlam completed in 2000 ph buffer and corrosion control, full implementation completed in 2007 Seymour filtration completed in 2009 Review requirements for additional rechlorination stations following filtration completion at Seymour and Capilano Capilano pump station and twin tunnels completed in 2015 Coquitlam ultraviolet treatment completed in 2014 Second Intake on the Coquitlam Source completion target WATER SAMPLING AND TESTING PROGRAM Metro Vancouver Program Table 1 outlines the water sampling and testing program undertaken by Metro Vancouver. This table is copied from the Greater Vancouver Water District Quality Control Annual Report Water sampling and testing as described in the table meets the requirements of the Water Quality Monitoring and Reporting Plan (WQMRP) for Metro Vancouver and part of the requirements for member municipalities. 4

The locations of these sample stations can be seen in Figure 1. In addition Metro Vancouver also has three sample stations located within the city and one immediately adjacent to the city limits to monitor the quality of the water being delivered to New Westminster. 5

In 2016, 3 samples were collected and tested for various metals and 12 samples were tested for disinfection byproducts. All samples were obtained by Metro Vancouver personnel and analyzed at the Metro Vancouver laboratory. Sample analysis results are sent simultaneously to both the City and Medical Health Officer. 7

8 The Drinking Water Protection Regulation requires 1 sample / 1000 residents on a monthly basis for cities with population between 5000 and 90,000 residents. During 2016 New Westminster had approximately 73,771 residents, which equates to 886 samples required annually. The total number of samples collected in New Westminster during 2016 was 744, from New Westminster stations, which is 16% below the number of tests as required by the DWPR. This shortfall is due to a combination of poor weather (frozen kiosks) and inaccessible sampling stations due to construction activity. New Westminster's population has increased significantly in the last few years ( ,000). As the population is projected to continue to increase, the number of samples required will also need to increase. Future locations for sampling stations are currently being considered including the new high density Victoria Hill development and Port Royal in Queensborough. In addition to obtaining and analyzing samples, the City undertakes an annual program of unidirectional water main flushing including notification to residents through media releases. Every City main is flushed to remove accumulated sediment in the months between February and May; areas of low flow are flushed more frequently to maintain chlorine levels. This is a very effective tool in protecting water quality. 3.0 DRINKING WATER PROTECTION ACT & REGULATION The Drinking Water Protection Regulation (DWPR) establishes the following microbiological standards for which samples must be analyzed and fall in compliance with: There must be non-detectable levels of Ecoli in any 100 ml of sample; 90% or more of the samples must have non-detectable levels of total coliform per 100 ml; No consecutive samples from the same site should have the presence of total coliforms; and No sample has more than 10 total coliform bacteria per 100ml. In addition to the requirements of the DWPR, a variety of parameters were tested including: Heterotrophic plate count (HPC), Free chlorine residual Turbidity Temperature Metals Disinfection by-products (DBPs), particularly trihalomethanes (THMs) and haloacetic acids (HAAs) 8

9 The monitoring results for both the DWPR required parameters and the additional parameters are presented in Section 3.1. Some of the additional parameters are intended to provide an early indication of potential water quality problems (i.e. HPC, chlorine residual, & turbidity). The remaining parameters are sampled less frequently and are intended to help characterize the quality of the water and any potential impacts from the water treatment process. There are no regulated concentrations for the additional parameters; however, the following levels are used to assess the acceptability of the sampling results. 1. To prevent bacterial re-growth a minimum residual chlorine concentration of 0.1 ppm is suggested by Metro Vancouver. To be conservative, a concentration of 0.2 ppm is the accepted target. 2. An HPC concentration of 500 CFU / ml is considered to be indicative of regrowth within the system 3. The Canadian Environmental Quality Guidelines specify a Maximum Acceptable Concentration of 1.0 NTU for turbidity. Results are presented for both 1 NTU and 2 NTU. 3.1 SAMPLE ANALYSIS RESULTS The microbiological and physical parameters that were sampled regularly are summarized in Table 3. The number of samples collected, as well as the minimum, maximum and average concentrations for chlorine residual, turbidity, temperature, and HPC are provided. The number of positive Total coliform and Ecoli samples are also summarized. The analysis performed on the City s water samples showed the drinking water supplied through the distribution system was compliant with the standards of the DWPR. Specific site samples did occasionally exceed the Canadian guidelines for chlorine residuals but on average the system is compliant, and consistent with previous years' results. The average chlorine residual objective of 0.2 ppm was met by all stations, including NW 331 (Trapp Road), a low flow, dead end main with chronically low residuals. All New Westminster sampling stations meet the average 0.1 ppm requirement. Table 4 identifies the sample sites and the percentage of samples with less than the guideline objective of 0.2 mg/l residual free chlorine. We have also included the percentage of samples with less than 0.1 mg/l residual free chlorine as Metro Vancouver data indicates that 0.1 mg/l is adequate to prevent bacterial re-growth. Figure 2 illustrates the average chlorine residual concentration graphically throughout the city. The city has developed a Water Master Plan which identifies the age and source of water and provides recommendations for future upgrades. Sites with lower chlorine residuals will be reviewed during the planning and scheduling for future water main works. The City is continuing to implement an asset management program which will aid in the maintenance and timely replacement of the city s potable water system. 9

10 There were 4 incidences of total coliform colonies identified in water samples within the New Westminster system. The 30 day average did not exceed 10% and no samples exceeded the 10 Total Coliform bacteria per 100ml criteria. No samples tested positive for Ecoli. The compliance with the DWPA is shown on Figure 4. Turbid water is delivered to customers if the source water is turbid or the direction of flow for water supply is reversed and sediment is stirred up in the pipeline. Turbid water complaints are often encountered during the annual flushing program as this procedure can disturb sediment in the water main. Turbidity is recorded for each sample taken from a city station, however only during heavy rainfall events is the Metro Vancouver turbidity recorded. Results for 2016 indicated the average turbidity was less than 1.0 NTU except for 9 individual New Westminster samples. Review of the individual turbidity readings for all samples indicated that 1.2 % of the samples exceeded 1 NTU and 0.05% of the samples exceeded 2 NTU. Similarly, HPC bacteria were monitored at each sampling site. The objective of fewer than 500 CFU per ml was met for all samples in 2016 except for one occurrence. Testing of disinfection by-products (DBPs), trihalomethanes (THMs) and haloacetic acids (HAAs) was initiated in The commissioning of the rechlorination stations in 1998 by Metro Vancouver increased the likelihood for the formation of DBPs and therefore the City s water supply is tested for these compounds at three locations on a quarterly basis. The Guidelines for Canadian Drinking Water Quality established the concentration for total THMs at 100 parts per billion (ppb) and 80 ppb for HAAs. A summary of sample results for THMs and HAAs is shown in Table 5. Review of the results indicates that THM levels measured were below the guidelines and that the concentrations are relatively constant. There were no samples of THMs or HAAs above the guidelines, and the overall DBP levels have been improving since Samples were also analyzed for various metal parameters during The results of the sampling are provided in Table 6. All of the samples were below the accepted Canadian Guideline Limits. The following message has been included at the request of the medical health officer. 10

11 A Public Health Message from the Medical Health Officer/ Drinking Water Officer Water Flushing Message Water from taps that are not used for several hours is good for washing or watering plants but not for drinking or cooking, as it may contain elevated levels of leads or copper. Run the 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. Conserving water is still important. Rather than just running the water down the drain, you could use the water for things such as watering your plants. 11

18 FUTURE SAMPLE ANALYSIS: In May of 2003, through an Order in Council of the Provincial Government, the Drinking Water Protection Act became law. Under the Act, the Health Authority at their discretion, add to the analysis requirements in the Act. The City population has reached 73,771 which requires 886 annual water sample tests. The City completes on average over 1000 tests at City sites to achieve the required frequency was a historical anomaly with only 743 tests. With a growing population the city is planning to coordinate with the FHA to identify potential future test sites. Possible preliminary locations include: Port Royal Phase I or II; Victoria Hill; Sapperton Both Port Royal and Victoria Hill are currently under development and increasing in population density, neither area has an existing test site within close proximity. Sapperton Industrial park and the future Sapperton Green Development are located on the perimeter of the distribution system and do not have a current test site. If two of the three locations were selected for testing on a weekly basis, an additional 104 water quality samples would increase the city s count to a minimum of 780 per year. Some of the locations will have to be sampled more frequently than once a week RESPONSE TO PROBLEMS AND IMPROVEMENTS PROPOSED Under Section 13 of the Drinking Water Protection Regulation, a water purveyor is required to have an emergency response plan to be implemented in the event of an emergency affecting the waterworks system. The City has completed a plan which includes response procedures in the event of loss of system integrity. This includes response to issues such as line breaks, vandalism, loss of pressure and chemical or microbiological contamination. The City undertakes an annual watermain replacement program targeted at water quality improvements. The program has historically replaced over 1% of the total length of watermain in the City per year and replaces unlined cast iron pipe with cement mortar lined ductile iron pipe. The City also annually undertakes a watermain flushing program and flushes every watermain in the City. The objective of the program is to remove any accumulated sediment and prevent bacterial regrowth. In addition, since 2000 the city flushes all dead end mains during periods of high water temperature to alleviate issues with water quality. In addition, dead end mains are being looped on an opportunistic basis as resources become available. Capital works will be prioritized through a combination of the ongoing Asset Management Program and the Master Water Servicing Study. 18

19 5.0 CONCLUSIONS 1. The combination of Metro Vancouver secondary disinfection stations, the City s annual watermain flushing program, the City s annual watermain replacement program and the City s program of flushing dead-end mains during periods of high water temperature have resulted in annual improvements in drinking water quality and general compliance with the DWPR in The City s water sample analysis results indicate compliance with the DWPR, except for number of samples in The City met the Canadian Drinking Water (CDW) Guidelines and typical system indicators 4. Poor water quality encountered in dead end mains during periods of high water temperatures has caused the City to continue with regular flushing of these lines through this period. 19
