Seepage from the Mine 2 spoils is .the probable cause <br />of elevated dissolved solids and sulfate in 006-AW-2. Although the <br />data is limited, I would suggest that there is some evidence of <br />impact from mining, however, at the present time it does not appear <br />CYCC Response <br />No response necessary. <br />MLRD Concern <br />Alluvial Wells <br />and no increasing trends are apparent. <br />FOIDEL CREEK <br />Inspection of Fiqure 14 indicates an event taking place in July of <br />1986 which has caused the conductivity of all Foidel Creek alluvial <br />wells to increase approximately 50~ since that time. This apparent <br />anomaly is also evident in the surface water quality of site 8 <br />(Figure 34). Please attempt to identify the development of a spoil <br />spring, initiation of mine discharge, or some other event that <br />would help explain this phenomenon. Other than some high Fall <br />values for iron and manganese, the overall quality is reasonable <br />CYCC Response <br />No response required. <br />MLRD Response <br />Spoil Wells <br />The spoil wells south of Foidel Creek exhibit elevated TDS, EC, and <br />sulfate values beginning in the summer of 1986. These data indicate <br />the spoil aquifer as being the possible source of dissolved solids <br />in the Foidel Creek alluvial wells. No definitive trend can be <br />
