Imported Soil at Ladera Linda Fields Clean and Safe

Transcription

1 January 206 Imported Soil at Ladera Linda Fields Clean and Safe Soil tests performed by an independent environmental consultant show that the soil brought to the Ladera Linda soccer field area by Palos Verdes American Youth Soccer Organization (PV AYSO) is clean. The soil satisfies the LAUSD s safe schools soil criteria, which are very strict standards designed to ensure the safety of students. A Palos Verdes Peninsula Unified School District (PVPUSD) legal representative contacted PV AYSO and requested that PV AYSO conduct soil sampling on the soil, which is intended for future use leveling the fields. PV AYSO immediately agreed to do so at its cost. PV AYSO offered three qualified environmental consultants that had no prior affiliation with PV AYSO. PVPUSD s legal representative picked one of the offered consultants, and the soil sampling and analyses were performed by that consultant. The selected consultant collected soil samples and analyzed the soil samples in accordance with LAUSD s updated Section 0440 Environmental Import/Export Materials Testing (revised August, 2008) and federal and state law and requirements. All soil analyses indicated no contaminants present above any relevant environmental standards. The standards used were extremely high because kids safety is the PVPUSD and PV AYSO s highest priority. PVPUSD and PV AYSO now consider this matter closed. PVPUSD and PV AYSO remain committed to providing world class opportunities for our children and have worked hand in hand to resolve any concerns regarding the soil brought to the Ladera Linda soccer field area. The two organizations look forward to continuing their long tradition of partnership for the betterment of our youth for years to come. Sincerely, Brent Daniel Regional Commissioner PV AYSO Region 0 Dr. Don Austin Superintendent Palos Verdes Peninsula Unified School District

2 LEYMASTER ENVIRONMENTAL CONSULTING, LLC SOILS REPORT (,00 Cubic Yards) Upper Ladera Linda Park 3220 Forrestal Drive, Rancho Palos Verde, CA INTRODUCTION On December 4, 205, at the request of PV AYSO, Leymaster Environmental Consulting, LLC (LEC) collected soil samples for laboratory analyses from approximately,00 cubic yards (CYs) of soil imported to Upper Ladera Linda Park in Ranch Palos Verde, CA (Figure Local Area Map). The approximately,00 cubic yards of soil are located on an undeveloped terrace above the existing soccer fields (Figure ). Sampling was conducted in conformance with the Los Angeles Unified School District s (LAUSD) Section Environmental Import/Export Materials Testing guidelines dated October, 20. Soil acceptance criteria are based on the LAUSD s Section , California Human Health Screening Levels (CHHSLs) and USEPA Region IX Soil Screening Levels (SSLs). Based on the analytical results, the,00 CYs of soil sampled are acceptable for use at the Upper Ladera Linda Park. SAMPLE COLLECTION All samples were collected by Charles F. Lindeman, an Environmental Professional, REA-II No. 2025, under California s former Registered Environmental Assessor program. Based on Table (Minimum Sampling Frequency) of Section Environmental Import/Export Materials Testing (LAUSD, October, 20), five soil samples were collected and analyzed from the estimated,00 CYs. Four soil samples were collected from soils spread across an area approximately 70 feet by 350 feet (SS- through SS-4), and one soil sample (SS- 5) collected from approximately 75 CYs stockpiled at the western end of the terrace. Sampling Methodology To ensure representative sample results, both single-point, non-composited (SS- through SS-5) and three-point composited soil samples (SS- A-B-C through SS-5 A-B-C) were collected from locations spaced across the imported soils (Figure 2 Soil Sample Locations). No blind duplicate sample was collected East Atherton Street, Suite 20 Long Beach, CA 9085 (562) FAX (562)

3 SOILS REPORT (,00 CYs) Upper Ladera Linda Park 3220 Forrestal Drive, Rancho Palos Verde, CA December 23, 205 Page 2 of 5 Soil samples collected for volatile organic compound ( VOC ) analysis by EPA Method 8260B (i.e., SS- through SS-5) were collected in accordance with EPA Preparation Method 5035 using 25-gram and 5-gram En Core samplers. The single-point samples for VOCs analyses were collected from depths of approximately six to nine inches below ground surface (bgs) spaced across the area of the imported soils (Figure 2). Soil samples collected from for metals, petroleum hydrocarbons, Semi-VOCs, PCBs, pesticides and herbicides analyses (i.e., non-vocs analyses) were collected into pre-cleaned, brass sleeves from depths of approximately six to nine inches bgs, two to three feet north ( A ), southeast ( B ) and southwest ( C ) of the single-point VOC sample locations. After collection, the ends of the brass sample sleeves were covered with Teflon sheets and plastic end caps affixed. All soil samples were properly labeled (e.g., SS--A, SS--B and SS--C) and sealed in plastic bags, placed in an ice-cooled container and immediately transported to Asset Laboratories (ELAP 2676) located at 060 Artesia Boulevard, Suite C, Cerritos, CA 90703, for analysis. Standard Chain-of-Custody protocols were maintained on all samples. The Chain-of-Custody Record was initiated in the field by LEC. Each time responsibility for custody of the samples changed, the receiving and relinquishing custodians signed the record and recorded the date and time of transfer of the samples. The laboratory signed for the receipt of the samples and returned a copy of the Chain-of-Custody Record to LEC. The Laboratory Report of Analytical Results and Chain-of- Custody Record are contained in Attachment A. LABORATORY ANALYSES The soil samples were analyzed for the following based Part 3.02 (E) of the Los Angeles Unified School District s (LAUSD) Section Environmental Import/Export Materials Testing (October 200):. Total Petroleum Hydrocarbons (TPH as diesel and oil) by EPA Method 805M 2. VOCs and TPH-gasoline by EPA Method 8260B (EPA Preparation Method 5035) 3.

4 SOILS REPORT (,00 CYs) Upper Ladera Linda Park 3220 Forrestal Drive, Rancho Palos Verde, CA December 23, 205 Page 3 of 5 DISCUSSION OF ANALYTICAL RESULTS Analytical results for all analyses performed on the,00 CYs of imported soils are tabulated in Table A and Table B (Analytical Results for,00 CYs Soil) which follows the text of this report. The laboratory report of analytical results and Chain-of-Custody Record are contained in Attachment A. Total Petroleum Hydrocarbons Total Petroleum Hydrocarbons as gasoline (TPH-gas) were not detected in any soil sample. TPH-diesel were detected at a maximum concentration of 3 milligrams per kilogram (mg/kg or parts per million). TPH-oil were detected in at a maximum concentration of 22 mg/kg. There is no CHHSL for TPH. However, the maximum level of long-chain petroleum hydrocarbons (i.e., TPH-diesel and TPH-oil) present in soils considered acceptable for use at an LAUSD school site is,000 mg/kg. The detected maximum concentrations of TPH-diesel (3 mg/kg) and TPH-oil (22 mg/kg) are two orders of magnitude below the LAUSD s soil screening level of,000 mg/kg for long-chain petroleum hydrocarbons. Volatile Organic Compounds With the exception of low levels of benzene in a single soil sample ( mg/kg in SS-2), VOCs were not detected in any soil sample. The USEPA Region IX Soil Screening Level (SSL) for benzene in residential soils is.2 mg/kg. The detected concentration of benzene ( mg/kg) is three orders of magnitude below the Region IX SSL for benzene in residential soils. Semi-Volatile Organic Compounds Semi-Volatile Organic Compounds were not detected in any soil sample. Polychlorinated Biphenyls Polychlorinated Biphenyls ( PCBs ) were not detected in any soil sample. Title 22 Metals With the exception of arsenic, all detected concentrations of Title 22 Metals are below their applicable CHHSL for residential soils.

5 SOILS REPORT (,00 CYs) Upper Ladera Linda Park 3220 Forrestal Drive, Rancho Palos Verde, CA December 23, 205 Page 4 of 5 Arsenic was detected at a maximum concentration of 8.6 mg/kg. The Cal-EPA s Department of Toxic Substances Control (DTSC) has determined that the naturally occurring background level for arsenic in Southern California soils is 2 mg/kg. Therefore, the detected concentrations of arsenic (<8.6 mg/kg) are within levels determined to be acceptable for school use. Hexavalent chromium (Cr 6+) was detected in a single sample (SS-5-ABC) at a concentration of 0.73 mg/kg. The detected concentration of hexavalent chromium (0.73 mg/kg) is two orders of magnitude below both the residential CHHSL of 7 mg/kg, and the LAUSD-specific soil screening level of 5 mg/kg for hexavalent chromium. Organo-Chlorine Pesticides Several organo-chlorine pesticides were detected at low levels. The types of organo-chlorine pesticides at the site were widely used in Southern California prior to being banned in the 970s and 980s; trace concentrations continue to be detected in soils throughout Southern Califorrnia. 4,4 - DDD was detected at a maximum concentration of 0.02 mg/kg; this is two orders of magnitude below the residential CHHSL of 2.3 mg/kg for 4,4 -DDD. 4,4 -DDE was detected at a maximum concentration of 0.06 mg/kg; this is two orders of magnitude below the residential CHHSL of.6 mg/kg for 4,4 -DDE. 4,4 -DDT was detected at a maximum concentration of mg/kg; this is two orders of magnitude below the residential CHHSL of.6 mg/kg for 4,4 -DDT. Dieldrin was detected at a maximum concentration of mg/kg; this is an order of magnitude below the residential CHHSL of mg/kg for Dieldrin. Total Chlordane was detected at a maximum concentration of mg/kg; this is an order of magnitude below the residential CHHSL of 0.43 mg/kg for Total Chlordane. Organo-Phosphorus Pesticides Organo-phosphorus pesticides were not detected in any soil sample. Chlorinated Herbicides Chlorinated herbicides were not detected in any soil sample.

6 SOILS REPORT (,00 CYs) Upper Ladera Linda Park 3220 Forrestal Drive, Rancho Palos Verde, CA December 23, 205 Page 5 of 5 DATA VALIDATION Matrix Spikes (MS) and Matrix Spike Duplicates (MSD) for several analyses were outside recovery criteria for some analytes due to matrix interference. However, the associated Laboratory Control Sample (LCS) recoveries were within acceptable recovery limits. The QA/QC data for the,00 CYs laboratory results did not reveal discrepancies or items of concern that would render the analytical data individually or collectively unusable for soil classification or risk/hazard assessment purposes. CONCLUSIONS Based on the analytical results, the,00 CYs of soil sampled are acceptable for use at the Upper Ladera Linda Park. Charles F. Lindeman Environmental Professional

Cooler temperature and sample preservation were verified upon receipt of samples if applicable. Information on sample receipt conditions including discrepancies can be found in attached Sample Receipt Checklist Form. Sample was analyzed within method holding time. Subcontracted Analyses: EPA 84 and 85 analyses were subcontracted to BC Labs. Analytical Comments for EPA 600B: Matrix Spike (MS) and Matrix Spike Duplicate (MSD) are outside recovery criteria on QC samples N A-MS and N A-MSD possibly due to matrix interference. The associated Laboratory Control Sample (LCS) recovery was acceptable. Analytical Comments for EPA 808: Matrix Spike (MS) and Matrix Spike Duplicate (MSD) are outside recovery criteria for some analytes on QC samples N A-MS and N A-MSD possibly due to matrix interference. The associated Laboratory Control Sample (LCS) recovery was acceptable. Analytical Comments for EPA 8082: Matrix Spike (MS) and Matrix Spike Duplicate (MSD) are outside recovery criteria on QC samples N B-MS and N B-MSD possibly due to matrix interference. The associated Laboratory Control Sample (LCS) recovery was acceptable. Analytical Comments for EPA 8270C: Results were J-Flag. "J" is used to flag those results that are between the PQL (Practical Quantitation Limit) and the calculated MDL (Method Detection Limit). Results that are "J" Flagged are estimated values since it becomes difficult to accurately quantitate the analyte near the MDL Artesia Blvd., Ste C, Cerritos, CA P: F: of 77 Page 3 of 7 35 W.
