The groundwater purged from the wells was discharged to the <br /> ground surface. Groundwater Monitoring Field Forms completed for the work are'attached. <br /> The groundwater samples were collected by filling laboratory supplied containers with groundwater <br /> directly from the disposable bailers. The sample containers were labeled, placed in a cooler chilled with <br /> ice, and delivered in accordance with chain-of-custody procedures to GeoAnalytical Laboratories, Inc., in <br /> Modesto, California, within 24 hours of sample collection. <br /> GROUNDWATER ELEVATIONS <br /> As specified in the MRP, groundwater level measurements were collected from-all ten monitor wells at <br /> the site. Groundwater elevation data is presented in Table 1, below. The water level measurements <br /> collected from the ten wells on May 12, 2004, indicate a groundwater gradient to the west. Groundwater <br /> Monitoring Field Forms containing field measurements are attached. <br /> Table 1 -Groundwater Elevation Data(May 12, 2004) <br /> a <br /> Monitor Well Well Collar Ground Surface Depth to Groundwater <br /> Elevation Elevation Water Elevation <br /> GW-1 13.80 11.0 9.49 4.31 <br /> GW-2 10.27 7.3 6.81 3.46 <br /> F" GW-3 11.14 8.2 7.98 3.16 <br /> GW-4 9.85 6.9 8.00 1.85 <br /> t ' GW-5 8.98 6.0 7.50 1.48 <br /> a <br /> GW-6 7.99 5.1 6.50 1.49 <br /> +` GW-7 8.62 5.7 6.52 2.10 <br /> DWS-1 7.76 6.4 4.66 3.10 I <br /> DWS-2 7.97 6.6 5.10 2.87 <br /> DWS-3 7.31 6.4 1 4.90 1 2.41 F <br /> + Measurements are in feet. <br /> Well collar elevation referenced relative to Condor Control Point l. <br /> F.' <br /> LABORATORY ANALYTICAL RESULTS <br /> The groundwater samples collected from the domestic wastewater system monitor wells were analyzed <br /> for nitrate as nitrogen (N), total Kjeldahl nitrogen (TKN), total dissolved solids (TDS), and specific ! <br /> conductivity (EC) by GeoAnalytical Laboratories, Inc. of Modesto, California. Laboratory certificates of <br /> analysis and chain-of-custody records are included in Attachment C.
