<br />Section 2 con[. <br />page 2 <br />Section 2.6 Trends <br />Basically there are no identifable problems with water quality <br />constituents. The trends for SAR, conductivity, pH, total dis- <br />solved solids (TDS) and water levels show little, if any, effect <br />from mining activities. Four wells - GA1, GA2, GD2 and GF-6 - <br />ahow a decrease in water levels but these are in close proximity <br />to active mining areas and this decrease is thought to be the <br />return to premining conditions after water levels were increased <br />by mining. These wells are located in undisturbed areas that <br />monitor ground water aquifers between mined areas. <br />The salinity data is presented as TDS levels instead of conduc- <br />tivity. Our conductivity data still produces a non-consistent <br />pattern which does not allow an accurate trend analysis to be <br />made. A piezometric surface for the Twenty-mile sandstone <br />aquifer was not produced. Ae previously discussed with the Divi- <br />sion, drawing a water level surface from two data points is of <br />little value. <br />
