Health Assessment for Washington County Landfill National Priorities List (NPL) Site, Lake Elmo, Washington County, Minnesota, Region 5. CERCLIS No. MND980704738

摘要

The Washington County Landfill is a National Priorities List site located in Lake Elmo, Washington County, Minnesota. Because of the leaching of contaminants from the landfill, elevated levels of lead and various volatile organic compounds (VOCs) are found in on-site and off-site groundwater. The clean-up goals for VOCs and the cumulative effect of exposure to various VOCs may cause an increased risk for potential adverse health effects if contaminated groundwater is used for potable water supplies in the future. Although lead (may not be site-related) was detected in residential wells and groundwater at concentrations of long-term public health concern, it cannot be determined if exposure to lead is currently occurring. The site is of potential public health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects. Human exposure to various VOCs may occur and may have occurred via oral (ingestion), dermal, and inhalation exposure. In addition, human exposure may occur, may be occurring, or may have occurred via oral (ingestion) exposure to lead (may not be site-related) in ground water.
