| 英文摘要: | The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), operated a grain storage facility at the northeastern edge of the city of Hanover, Kansas, from 1950 until the early 1970s. During this time, commercial grain fumigants containing carbon tetrachloride were in common use by the grain storage industry to preserve grain in their facilities. In February 1998, trace to low levels of carbon tetrachloride were detected in two private lawn and garden wells near the former grain storage facility at Hanover, as part of a statewide USDA private well sampling program that was implemented by the Kansas Department of Health and Environment (KDHE) near former CCC/USDA facilities. In July 2007, the CCC/USDA sampled indoor air at nine residences on or adjacent to its former facility to address the residents concerns. Low levels of carbon tetrachloride were detected at four of the nine homes. Consequently, the CCC/USDA has conducted investigations, under the direction of the KDHE, to determine the source and extent of the carbon tetrachloride contamination that might be associated with the former facility. In July 2007, the CCC/USDA sampled indoor air at nine residences on or adjacent to its former facility to address the residents concerns regarding vapor intrusion (VI). Low levels of carbon tetrachloride were detected at four of the nine homes. Because carbon tetrachloride found in private wells and indoor air at Hanover might be linked to historical use of fumigants containing carbon tetrachloride at its former grain storage facility, the CCC/USDA has conducted investigations to determine the source and extent of the carbon tetrachloride contamination that may be associated with the former facility. The results of the comprehensive investigation at Hanover indicate that no unacceptable risk to human health currently exists from exposure to surface and subsurface soils by either ingestion, inhalation or dermal contact. No risk is associated with potential exposure to contaminated groundwater at Hanover. No drinking water wells are known to exist in Hanover, and the drinking water supply comes from RWD No.1 at Lanham, Kansas, located 6.5 mi north of Hanover. Limited potential risk was identified due to exposure to indoor air contaminated with carbon tetrachloride, but this risk has been mitigated, thereby removing this threat to human health. Radon is prevalent in the community, at concentrations exceeding the level at which the EPA recommends additional measures (testing and/or mitigation). The recommended testing and mitigation (if needed) are the responsibility of the homeowners. In the current condition in which no private wells are used for drinking water in the affected area, no unacceptable human health risk from carbon tetrachloride is associated with the identified impacted media at the Hanover site. |
