5 <br /> deterioration from human-induced pollution where contamination has <br /> occurred. It is important to note that it was not designed to prevent or <br /> control naturally occurring pollution. <br /> Purpose and Objectives for Climax and Henderson's Groundwater 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 ground 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 Meet 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 ground water <br /> that may result in contaminant loading into surface water. <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 proposed 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 />
