Thus, no IRAP sampling (influent, mid-point, and <br /> effluent) or Waste Discharge Requirements (WDR) sampling (total dissolved solids <br /> analyses at monitoring wells M-7A and M-1 5A)were performed during this quarter. <br /> ECM sent all of the samples to TestAmerica Laboratory in Pleasanton, California for <br /> analysis using either United States Environmental Protection Agency (USEPA) Method <br /> 8260B (monitoring wells and non-potable supply wells) or USEPA Method 524.2 (drinking <br /> water supply wells).

Table 1 through Table 4 present <br /> pertinent well information, water level elevation, and water quality analytical data. <br /> Appendix A and Appendix B include field logs and laboratory reports with chain-of- <br /> custody information, respectively. <br /> Please feel free to contact Binayak Acharya at (661) 255-1693 with any questions or <br /> concerns. <br /> Respectfully, <br /> ECM Consultants, Inc. <br /> Binayak Acharya Eric Collins, PG <br /> Program Manager Senior Hydrogeologist <br /> Enclosures: Figures (4) <br /> Tables (6) <br /> Appendices (2) <br /> cc: Sven Vetter— NUSA (e-mail) <br /> Distribution List <br /> a The well at 415 Parallel Avenue was not sampled because there was no access to the property.
