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 2001 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 />Monitoring Well AA-1: <br />Quarter Date pH <br />su Temp °C Depth <br />feet Cond. <br />umhos/cm Oil or <br />Grease <br />15` 2/19/01 7.6 11.9 12.18 4900 No <br />rZnd 6/1$/01 8.0 17,1 12,56 5.10 NO <br />3r0 8/13/01 7.6 19.6 12.94 4900 No <br />4"' 11/12/01 7.8 14.8 12.32 5000 No <br />• <br />L J <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 />151 2/19/01 7.0 7.3 8.84 490 No <br />2nd 6/18/01 7.6 12.2 7.65 350 NO <br />3`d 8/13!01 7.3 16.9 8.42 460 No <br />4`h 11/12/01 7.4 14.4 8.93 470 No <br />Findings: <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 for this well are similar to historic averages. Not enough water <br />was available in AA-3 to perform full suite analysis for the 4`" quarter 2001. <br />-2- <br />
