Impact of Lead-zinc Mining on Distribution of Major and Minor Trace Elements in Water, Sediment and Soil in Van Stone Mine, Stevens County, Washington

Book Description
"In order to evaluate the effect of lead-zinc mining on the distribution of major and trace elements in water, sediment and soil, a study of the Van Stone mine (in Stevens County, Washington) and its surrounding areas has been undertaken. The mine has been intermittently worked for Pb-Zn deposits, which are hosted in the Metaline Formation. The milled waste and slurry are stored in two tailings ponds, one of which was abandoned in the early seventies and has been severely breached. Both ponds are uncapped and have no retaining barriers. Water, stream sediment and soil samples, collected at VSM near the tailings pond and Onion Creek, were digested according to EPA method SW 846 and analyze for 23 elements by electrothermal and flame atomic absorption, inductively coupled argon plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry. Concentrations of Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, Tl, V and Zn were found to be higher than their background values in water at VSM. In water, higher concentrations were observed for several trace elements (Sb, to 44.8 ug/L; Mo, to 16.3 ug/L; Pb, to 86.1 ug/L, and Zn, to 434 ug/L). However, trace element concentrations in water decrease sharply downstream and are below the maximum contaminant level specified for drinking water. In sediment, concentrations range to as much as 16. mg/kg Cd, 847 mg/kg Pb and 4270 mg/kg Zn, and are highest around the abandoned pond. Near the tailings pond, elevated levels of Pb (756 mg/kg) and Zn (1510 mg/kg) occur in the soil. Different indices for contamination, such as three times the background level, metal/Al and metal/Fe ratios, enrichment factor and relative atomic variation, indicate an enrichment of Cd, Pb and Zn in VSM sediment. Mobility and potential bioavailability of heavy metals are low due to the high pH level and presence of carbonates. Under present physico-chemical conditions, contamination of water is insignificant.and enrichment of heavy metals mainly occur in sediment and soil. Although contamination of water, sediment and soil at VSM is very minor compared to several Pb-Zn deposits in non-carbonate hosted rocks, preventive measures should be taken to retain the milled waste from assimilating with the stream sediment and topsoil"--Document.
