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 2003 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` 2/17/03 7.3 11.5 12.82 4300 No <br />.2nd 5/19/03 7.4 14.0 11.85 4300 NO <br />3'd 8/04/03 7.4 19.8 13.60 4680 No <br />4"' 12/12/03 7.7 10.7 12.43 4600 No <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 2/17/03 7.4 7.1 8.93 520 No <br />2nd 5/19/03 7.6 8.8 5.64 340 No <br />3rd 8/04/03 7.4 15.4 8.32 515 No <br />4`" 12/12/03 7.7 8.4 9.02 440 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. Not enough water was available in AA- <br />1 to perform full suite analysis for the 4'" quarter 2003. <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 2003. <br />-2- <br />
