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 2004 and pertinent water <br />quality parameters are found below. Depth to water is measured from the top of the <br />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, "Figure 11 ", in Appendix A. Graphs and well <br />completion diagrams are presented in Appendix B. <br />Monitoring Well AA-1: <br />Quarter Date pH Temp °C Depth Cond.

Not enough water was available in <br />AA-1 to perform full suite analysis for the 4d' quarter 2004. <br />AA-3 The field parameters for this well are similar to historic averages.
