Therefore, all <br />recorded monitofng events are considered Operational. <br />Alluvial Wells AW-7 through AW-9 are located south of Old State Highway 133, near the entrance to the mine. <br />They were installed in 1999 as the result of PR-03. <br />There is no Baseline Collection possible for points initiated after the influence of mining. <br />Figure No. 165
