Health Assessment for Cherokee County-Galena Subsite National Priorities List (NPL) Site, Galena, Cherokee County, Kansas, Region 7. CERCLIS No. KSD980741862

摘要

The Cherokee County site is on the National Priorities List. Mine wastes resulting from the shaft excavations, ore milling processes, and smelter operations had been disposed of on the ground near mine shafts and former mill sites. Maximum contaminant concentrations in the on-site areas consist of lead (3,880 parts per million (ppm) in surface mine wastes, 550 ppm in surface soils, 390 parts per billion (ppb) in private drinking water wells, 290 ppb in surface water from subsidence or open pit mine ponds, 67 ppb in other surface waters (creeks or rivers)); cadmium (60 ppm surface mine wastes, 12 ppm in surface soils, 180 ppb in private drinking water wells, 200 ppb in surface water from subsidence or open pit mine ponds, 140 ppb in other surface water (creeks or rivers)); and, chromium (total) (120 ppb in private drinking water wells). The site is of public health concern because of the risk to human health caused by the probable human exposure to hazardous substances at concentrations that may result in adverse health effects. Human exposure to heavy metals is probably occurring via ingestion, dermal, or inhalation exposure to contaminated surface soils, mine wastes, surface waters, or contaminated foodstuffs.
