CEE04J Moonlight Beach Sewer Pump Station GROUND WATER ANALYSIS, PROPOSED SEWER PUMP STATION IMPROVEMENTS, MOONLIGHT BEACH SEWER PUMP STATION, ENCINITAS, CALIFORNIA PREPARED FOR: KENNEY/)ENKS CONSULTANTS 16855 West Bernardo Drive, Suite 360 San Diego, California 92127 Project No. 600666-001 December 15, 2004 Leighton Consulting , Inc. A LEIGHTON GROUP COMPANY 4 JP Leighton Consulting, Inc. A LEIGHTON GROUP COMPANY December 15, 2004 Project No. 600666-001 To: Kennedy/Jenks Consultants 16855 West Bernardo Drive, Suite 360 San Diego, California 92127 Attention: Mr. Matt Tebbetts, P.E. Subject: Ground Water Analysis, Proposed Pump Station Improvements, Moonlight Beach Sewer Pump Station, Encinitas, California In accordance with your request and authorization, this letter presents the results of our recent analytical testing of ground water at the Moonlight Beach Sewer Pump located in Encinitas, California (Figure 1). The objective of the sampling and analysis was to identify potential contamination of the ground water (as identified by the California Regional Water Quality Control Board (RWQCB) San Diego Region, Order Number 2001-96) that could affect the design of a dewatering system and proposed discharged to Cottonwood Creek. The discharged ground water will ultimately drain westward to the surf zone at Moonlight Beach. Given the preliminary status of this project, cleanup goals are not considered to be applicable to this project. It is our understanding that the only criteria for this project is the RWQCB Order No. 2001-96,NPDES Permit Number CA G919002. On December 1, 2004, representatives from our office collected one ground water sample, GW- 1, from monitoring well, MW-1 (see Figure 2). Consistent with the County of San Diego, DEH purging and sampling protocols, the ground water sample was collected in laboratory-provided sample containers. Sample containers were capped, labeled and immediately placed in a cooler with bagged ice and transported to EviroMatrix Analytical, Inc. for analytical testing. Copies of Chain-of-Custody forms and Laboratory Reports are included in Appendix B. Consistent with Order Number 2001-96, Discharge Specification — B.3 (Discharge to the Surf Zone), analytical testing of the water sample included: EPA Method 8260B (Volatile Organic Compounds), EPA Method 8270C (Semivolatile Organic Compounds), EPA Method 8082 (Polychlorinated Biphenyls), -- 3934 Murphy Canyon Road,Suite 8205■San Diego,CA 92123-4425 858.292.8030■Fax 858.292.0771 ■www.leightonconsulting.com 600666-001 EPA Method 8081A (Organochlorine Pesticides), Organotin Compounds by GC-FPD, — . EPA Method 8015B (TPH-gas and diesel) EPA Method 200.7, 200.8 and 245.1 (Metals) EPA Method 150.1 (pH) SM 2540 D and F (TTS and Settleable Solids) SM 2130 B (Turbidity) SM 3500 Cr D (Hexavalent Chromium) SM 4500 (Dissolved 02,CL, HS2,NH3, and CN) SM 9221 B and E ( Total and Fecal Coliform) Laboratory analytical results for the ground water sample typically indicated conformance with the criteria presented in Discharge Specification—B.3, excluding four metals, chlorine, dissolved oxygen, settleable solids, total suspended solids and total coliform, which were detected in the sample. Table 1, Detected Analytes, summarizes all of the detected concentrations of the analytes and highlights those that exceed the Discharge Specification - B.3. Laboratory Reports are presented in Appendix B. Based on the analytical results, we anticipate that treatment of the ground water prior to discharge will be required. We recommend that a consultant or contractor specializing ground water treatment and dewatering be retained to evaluate the data collected and advise the design team on appropriate treatment methods and/or potential alternatives. If you have any questions regarding the information presented above,please contact this office. We appreciate this opportunity to be of service.
