Groundwater <br />Under the reduced sampling program. Salt Creek is required to <br />monitor only well GW-6 at the proposed waste rock disposal area. <br />The well has been dry since installation. Salt Creek has checked <br />the water levels in the wells on its own accord to ensure that the <br />wells are intact and to have some continuous record of the <br />elevation of groundwater in the area. Results of this sampling is <br />shown on Table 3. <br />The results are also compared to the average water levels for each <br />well that were obtained during the base sampling year. The three <br />wells (GW-2, 3, 8 8) which are near the irrigated cropland in the <br />valley show an increase in the elevation of groundwater. Note <br />that all three of the samples taken are at the end of the <br />irrigating season. This result compares with the results obtained <br />during the base year that also showed increased water elevation <br />during the irrigating season. The other wells monitored show <br />nearly no change in water elevation when compared to the base <br />year. <br />From the above results it does not appear that the mining <br />operations are effecting the East Salt Creek hydrologic regime. <br />If there are questions or if I can be of further assistance please <br />contact me. <br />Sincerely, <br />~G~~ <br />John M.
