Analysis of trace metals indicates low concentrations. <br />Aluminum and iron were detected in all samplings, higher values <br />being reported during high flow events (Appendix I). Manganese <br />and zinc were also sampled and found in only trace amounts. <br />Mining operations at the Chimney Rock Mine appear to have <br />little or no effect on the quantity of area surface waters. This <br />may be due to the mines inactive status during 1985 through 1987. <br />However, small amounts of water are pumped from Stollsteimer Creek <br />during the summer months for dust control purposes. Sediment <br />control ponds established on the disturbed areas eliminated runoff <br />of surface waters from the mine site. Copies of pond inspection <br />reports completed quarterly for each pond are contained in <br />Appendix 3. During 1987, no discharge was recorded from any of <br />the sediment ponds. All NPDES forms filed with the Department of <br />Health are also contained in Appendix 3. <br />GROUND WATER MONITORING <br />Monthly ground water sampling for water level were conducted <br />at each of the designated alluvial and deep wells during the later <br />portion of each month. Quarterly water quality samples were <br />collected during March, June, September and December. <br />Methods <br />During monthly visits to each station, water level <br />measurements were made using a Soil-Test Indicating Depth Meter <br />with a conductance bridge. Levels were recorded from the top of <br />the well casing and reported as such. <br />Water quality samples were collected during the quarterly <br />field trips. Samples were obtained from a hand bailer, grabbing <br />at least three casings of water prior to sample collection. <br />Parameters of temperature, pH and conductivity were made in the <br />field. All sampling equipment and handling procedures were <br />consistent with those described in the surface water methods <br />section of this report. <br />Results <br />Results of all well water measurements collected during 1985 <br />through 1987 are presented in Appendix 2 with major parameters <br />summarized in Table 1. Information concerning well depth and <br />completion is also presented in the Appendix. <br />
