<br />~~ . <br />4.8.f.5 Operational Surface Water QualRv <br />Numerous samples have been collected at the surtace water montoring sites and a few analyses of the <br />water in the settling ponds have been conducted. Samples which were collected in 1977 or later are <br />inGuded in the operational monitoring table. Table 2.7-18 gives the premine surtace water quality. <br />Most of the drainages were not disturbed at the start of mining and therefore some of the resufls <br />presented in this section are baseline concentrations. Table 4.8-8 gives concentrations for total <br />suspended solids (TSS), total dissolved solids (TDS), condudivily, pH, total iron, total manganese and <br />oil and grease for the surtace water sites. Table 4.8-11 in Section 4.8.5.1 lists the locatbns of the pre- <br />mining surface water sties. Only a few samples in 1977 were measured from sites SI, Sz, S3 and S4 <br />because these are not in the acilve area. Numerous data are given for the Johnson, No Name, Coyote <br />and Buzzard Gulch sites. <br />• <br />a-zos _ - P~- ~} _ . <br />_ ~~.'L13~199~ .--.. -.- <br />
