• <br /> <br /> <br />GROUND WATER MONITORING <br />Quarterly water samples are collected at monitoring wells AA-1 and AA-3 using a hand <br />bailer. The results of groundwater data collected during 1998 and pertinent water quality <br />parameters are found below. Depth to water is measured from the top of the steel casing on AA- <br />l and top of the 2-inch PVC pipe for AA-3. The location of the alluvia] wells can be found on <br />map, "Figure 11", in Appendix A. Graphs and well completion diagrams are presented in <br />Appendix B. <br />Monitoring well AA-1 was destroyed by the November 1997 slide and has not been <br />replaced. <br />MonitorinE Well AA-1: <br />Quarter Date pH <br />- su Temp °C Depth <br />feet Cond. <br />umhos/cm TDS <br />ppm Oil or <br />Grease <br />1" Destroyed by Slide <br />end Not Replaced <br />3i° <br />4's <br />Monitoring Well AA-3: <br />Quarter Date pH <br />su Temp °C Depth <br />feet Cond. <br />umhos/cm TDS <br />ppm Oil or <br />Grease <br />1" <br />2nd 6/30/98 7.6 11.8 6.3 240 120 None <br />3ro 8/10/98 6.7 15.6 8.0 580 290 None <br />4'" 11/16/98 7.6 12.8 8.3 540 270 None <br />Findines: <br />AA-1 No laboratory results are available for AA-1 since this well was destroyed in November <br />1997 and laboratory samples are typically collected in December. <br />AA-3 The field parameters for this well are similar to historic averages. <br />-~- <br />
