MONITORING - Water Quality <br /> Attached is water quality data for; <br /> 1) Mayflower Millsite area <br /> a) Animas River above (AR3. 5) and below (AR4) complex. <br /> 2) American Tunnel area <br /> a) Cement Creek above (CCl) and below (CC2) complex. <br /> b) Springs in the area of the now reclaimed waste dump <br /> (ATS1, ATS2) . These springs no longer flow from their <br /> original sites because of the waste dump reclamation <br /> and are no longer sampled. Copies of old data was not <br /> included. <br /> MONITORING - Discussion of Water Quality Monitoring Results <br /> 1) Mayflower Millsite area <br /> The Animas River monitoring results continue to exhibit <br /> increased zinc and manganese concentrations between <br /> upstream and downstream monitoring points although the <br /> differential for zinc appears to have been reduced as a <br /> result of the completed diversions and reclamation <br /> projects . <br /> 2) American Tunnel area <br /> Cement Creek monitoring shows metals concentrations are <br /> similar between the points with some elevation for most <br /> metals between the upstream and downstream points. The <br /> metals with the largest increase are iron, manganese and <br /> zinc. <br /> The seep ATS2, originally from the toe of the American <br /> Tunnel waste dump, has either relocated or dried up. The <br /> seep ATS1 appears to have disappeared or relocated due to <br /> the reclamation of the waste dump. <br />
