Health Assessment for Twin Cities Air Force Reserve Base Small Arms Range Landfill, Minneapolis, Minnesota, Region 5. CERCLIS No. MN8570024275

摘要

The Small Arms Range Landfill of the Twin Cities Air Force Research Base is listed on the National Priorities List. On-site contaminants of concern include mercury, chromium, cadmium, lead, zinc and various volatile organic compounds (VOCs). However, sampling results have only been reported for mercury (2 ppb) and 1,2-dichloroethylene (14 ppb) in downgradient monitoring wells. Chromium was detected as paint filters, through EP toxicity testing, at 53 ppm. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of exposure to hazardous substances. Information is not currently adequate to determine more definitively whether a public health threat exists.
