3.0 SOLID WASTE MONITORING <br /> During the first quarter 2007 the French Camp Landfill did not receive waste and the site <br /> has been formally closed. (Appendix A). <br /> 4.0 WATER QUALITY MONITORING <br /> 4.1 SAMPLING AND LABORATORY ANALYSES <br /> All of the groundwater monitoring wells and surface water monitoring points were <br /> sampled on February 27, 2007. Prior to collection of samples, depth-to-water <br /> measurements were recorded for all groundwater monitoring wells. Due to the final <br /> cover construction, the casing for leachate monitoring well MW-1A was extended but not <br /> the pump's tubing. An attempt to pull the pump and extend the tubing was performed, <br /> however, due to curvature in the well casing,the pump became lodged in the well and <br /> can no longer be sampled. Following approval from the RWQCB,well MW-lA was <br /> abandoned in April 2007. <br /> A single sample set was collected from each sampling point(groundwater,leachate, and <br /> surface water) and analyzed for the parameters stipulated in RWQCB Order No. R5- <br /> 2004-0159, and summarized in Table 1. Water quality samples were also analyzed in the <br /> field for dissolved oxygen,turbidity,temperature, specific conductance, and pH and the <br /> field measurements were recorded on well data sheets. The groundwater monitoring <br /> wells and surface water monitoring points were sampled in accordance with the sampling <br /> and analysis procedures detailed in Appendix B. Well data sheets,raw laboratory data, <br /> certificates of analyses, and chain-of-custody records for the sampling program are <br /> included in Appendix C. The laboratory analyses and field results for groundwater wells <br /> and surface water sampling stations are summarized in Tables 2 through 5. <br /> 4.2 QA/QC RESULTS <br /> The QA/QC program completed for the first quarter 2007 water quality monitoring event <br /> included analyses of one duplicate sample, one field(ambient)blank, one trip blank, and <br /> one laboratory method blank. The trip, field, and laboratory method blanks were <br /> analyzed for volatile organic compounds (VOCs)by EPA Method 8260. Trace <br /> concentrations of chloroform were detected in the QA/QC ambient blank sample during <br /> the first quarter 2007 monitoring period. However,none of the primary samples <br /> contained chloroform. Of note,bromoform,bromodichloromethane, and <br /> dibromochloromethane were detected in the primary samples collected from upstream <br /> surface water station SW-2. However, during the previous monitoring period these <br /> constituents were identified as suspected laboratory contaminants associated with the <br /> VOA containers. <br /> DA2003_0217C_woldoc <br /> 2 Geologic Associates <br />
