• GROUND WATER MONITORING - <br />Quarterly water samples are collected at monitoring wells AA-1 and AA-3 using a <br />hand bailer. The results of groundwater data collected during 2000 and pertinent water <br />quality parameters are found below. Depth to water is measured from the top of the steel <br />casing on AA-1 and top of the 2-inch PVC pipe for AA-3. The location of the alluvial wells <br />can be found on map, "Figure 11", in Appendix A. Graphs and well completion diagrams <br />are presented in Appendix B. <br />AA-1 was replaced this year and sampling has resumed. <br />Monitoring Well AA-1 (NEW): <br />Quarter Date pH <br />su Temp °C Depth <br />feet Cond. <br />umhos/cm Oil or <br />Grease <br />15' See Notes <br />2nd 5/15/00 7.6 16.4 12.09 4600 None <br />3'd 8/15/00 7.3 20.8 12.22 5000 None <br />4'h 11/21/00 7.8 10.8 12.29 5300 None <br />• Monitoring Well AA-3: <br />Quarter Date pH <br />su Temp °C Depth <br />feet Cond. <br />umhos/cm Oil or <br />Grease <br />15' See Notes <br />2nd 5/15/00 7.9 10.9 6.92 340 None <br />3`d 8/15/00 7.4 16.8 8.24 490 None <br />4"' 11/21/00 7.8 11.3 8.5 520 None <br />Findings: <br />Note: First quarter monitoring was inadvertently omitted from sampling this year. <br />AA-1 The field parameters for this well are within well water range, but since it is a new <br />well, there is not historical data to compare it to. <br />AA-3 The field parameters forthis well are similarto historic averages. Not enough water <br />was available in AA-3 to perform full suite analysis for the 4`" quarter 2000. <br />• <br />-~- <br />
