<br />5 <br />deterioration from human-induced pollution where contamination has <br />occurred. It is important to note that it was not designed t.o prevent or <br />control naturally occurring pollution. <br />Purpose and Objectives for Climax and Henderaon's Groundwat~ar TR's <br />1. Characterize ground water flow conditions to provide an <br />understanding of physical movement of ground water within the area. <br />Based on ground water movement data, define the potentially affected <br />area. <br />2. Characterize the ground water quality conditions to provide a basis <br />for evaluating the potential nature and extent of c~round water <br />quality effects. <br />3. Define hydrogeologic transport pathways to groundwater receptors and <br />to surface water and evaluate potential water quality effects at <br />these points. <br />Required Tasks to Beet Specified Objectives (some already done) <br />1. Characterize background water quality in all aquifers with potential <br />to be affected. <br />2. Investigate and document discharges from mines, springs and seeps in <br />the potentially affected area including discharge rates and water <br />quality. <br />3. Characterize the nature and extent of contamination in c~round water <br />that may result in contaminant loading into surface wager. <br />4. Identify all potentially affected ground water uses and users. <br />5. Characterize ground water/surface water interaction in the <br />potentially affected area. <br />6. Characterize ground water flow directions, hydraulic gradients, <br />hydraulic conductivity, and water quality in all potentially <br />affected aquifers. <br />Recommended Procedure (some already done) <br />1. A site description of the potentially affected area F~roposed for <br />characterization. Include location, study area boundaries and <br />justification, watershed description, location and description of <br />classified stream segments, topography, land and water use, mining <br />history, climate, and a description of terrestrial and aquatic <br />ecosystems. <br />2. Present a proposal for field reconnaissance and water sampling <br />activities associated with mine discharge and spring and seep <br />
