1.5 Well Survey <br /> The monitoring wells were surveyed by Siegfried Engineering, Inc., licensed land surveyors located <br /> in Stockton, California. Tabulated survey information and surveyor field notes are provided in <br /> Appendix D. <br /> 1.6 Laboratory Analytical Results <br /> Groundwater results were compared to the Maximum Contaminant Levels(MCLs)including federal, <br /> primary, and secondary California MCLs or Action Levels, as applicable. <br /> The federal MCL and California-specific primary MCL were not exceeded for any of the <br /> constituents. <br /> The California DHS Secondary MCL or Action Level was exceeded for iron, manganese, and TDS. <br /> In addition to the MCLs, the results were compared to the Water Quality Limits (RWQCB, August <br /> 2003) including, but not limited to: the California Office of Environmental Health Hazard <br /> Assessment (OEHHA) Public Health Goals, USEPA IRIS Reference Dose as a Drinking Water <br /> Level, USEPA Suggested No-Adverse-Response-Levels(SNARLS), USEPA Taste&Odor/Welfare, <br /> and California EPA Cancer Potency for Drinking Water.As a result, it was determined the USEPA <br /> SNARL was exceeded for sodium. <br /> TPH and VOCs were not detected in the groundwater sample from MW-7A. <br /> The reported concentrations at MW-7A are similar to, or less than, those reported in other wells <br /> within the current monitoring well network. The analytical results are provided in Table 1. In <br /> addition, laboratory reports are provided in Appendix E. <br /> MW-7A Install Report Stockton,CA <br /> Cove Contractors 3 Project No.04.20090407.00 <br />
