GROUND WATER MONITORING <br />Quarterly water samples were collected at monitoring wells AA-1 and AA-3 using <br />a hand bailer. The results of groundwater data collected during 2010 and pertinent <br />water quality parameters are found below. Depth to water is measured from the top of <br />the steel casing on AA-1 and top of the 2-inch PVC pipe for AA-3. The location of the <br />alluvial wells can be found on map, AFigure 11", in Appendix A. Graphs and well <br />completion diagrams 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 />1 S 2/23/10 7.3 10.5 12.48 2200 No <br />2621 5/25/10 7.6 13.4 12.17 1420 No <br />3` 8/09/10 7.3 20.2 13.41 2300 No <br />4 11/1/10 7.2 12.2 13.46 2300 No <br />Monitorina Well AA-3: <br />Quarter Date pH <br />Su Temp °C Depth <br />feet Cond. <br />umhos/cm Oil or <br />Grease <br />1 s 2/23/10 7.7 8.7 8.89 1210 No <br /> 5/25/10 8.0 8.8 6.54 850 No <br />3` 8/09/10 7.6 20.6 8.38 1180 No <br />4 11/01/10 7.5 12.6 8.77 1550 No <br />Findings: <br />A sample for a full suite analysis was obtained from both wells during May. <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. <br />AA-3 The field parameters for this well are similar to historic averages. <br />-2- <br />
