-- (i,e., portal drainage) for cadmium, zinc and copper, which enter the creek as surface flows or seeps. a Additional source areas (waste rock piles and mill area) are not significant load sources in the spring and generally contribute no load in the fall unless a precipitation event occurs. a The sediments sampled both in Railroad Creek (above, adjacent, and downstream of the Site) as well as Lake Chelan (at Lucerne bar and the mouth of the Stehekin River) indicate similar concentrations of metals, except for copper and zinc which are slightly elevated (approximately twefold) when compared to the upstream and reference sites. However, the copper and zinc are anticipated to be present in the relatively inert stable iron oxyhydroxide precipitates due, to the neutrd pH in both Railroad Creek and Lake Chelan. \U)M-SEAI\VOLI\COMMOMWP\*~~~~~~\~~M)~Q~ 6-53 1169MOU)19Uuly 27.1999,4:11 PM;DRAFT FINAL RI REPORT
