Banta, <br />Division D:reclor <br />FROM: Tim King <br />~/ ~ RE: ~Nucla Annual Hydrology Report `~.e ~~~] <br />On this date I reviewed the Nucla Mine AHR. The frequency of monitoring for <br />surface water is once per month for field parameters, and once per quarter for <br />full suite analysis. Obviously, if there is no flow, no analysis can be <br />conducted. This no flow situation occurs in a minority of cases. <br />The frequency of monitoring for ground water is once per quarter for field <br />parameters and full suite analysis. It appears that the Nucla Mine is in <br />compliance with the frequency of monitoring as outlined above for both surface <br />and ground water. <br />After full suite analysis of all sites, it appears that surface water sites <br />show Aluminum as the parameter exceeded most often, with Iron and Manganese as <br />secondary exceedances. Ground water sites show Manganese as the parameter <br />exceeded most often, Iron as the secondary exceedance, and Aluminum and total <br />dissolved solids as minor exceedances. <br />/lac <br />4598E <br />~I~vn~`'"n'1 ~rnrn.or ('der lV <br />-S-~ ~C.1 0~ ~uXLCfdl~yr{ <br />
