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 2009 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 2/24/09 7.6 4.5 8.7 970 No <br />2" 5/12/09 7.6 14.0 11.0 2900 No <br />3r 8/03/09 7.6 20.5 13.52 3200 No <br />4 11/09/09 7.4 15.2 13.74 2500 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 />1 S 2/24/09 7.8 8.9 8.05 1150 No <br /> 5/12/09 7.7 8.7 5.86 460 No <br />3r 8/03/09 8.1 19.8 8.43 1750 No <br />4 11/09/09 7.4 15.1 9.01 1580 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-
