Health Assessment for Montana Pole and Treating Plant, Butte, Montana, Region 8. CERCLIS No. MTD006230635

摘要

The Montana Pole and Treating Plant Site is on the National Priorities List. The 40-acre site is a former wood treatment facility and is located in Butte (Silver Bow County), Montana. Operations consisted of preserving utility poles, posts, and bridge timbers with pentachlorophenol (PCP) and other related compounds. Preliminary on-site sampling results have identified PCP. In addition, polychlorinated biphenyls were detected in groundwater. Preliminary off-site groundwater sampling was reported to have identified PCP. It was reported that dioxin was identified on-site. Various volatile organic compounds and polyaromatic hydrocarbons were also reported. The site is considered to be of public health concern because of the risk to human health caused by the likelihood of human exposure to hazardous substances. Direct contact with and inhalation of contaminated soil along with possible ingestion of and direct contact with contaminated groundwater are the likely exposure pathways. Off-site sampling of groundwater, soil and sediment, and air are necessary to determine the potential for adverse public health effects.
