Health Consultation: Evaluating Post-Filter Residential Water Samples Near Baghurst Drive National Priorities List Site, Upper Salford Township, Harleysville, Montgomery County, Pennsylvania. EPA Facility ID: PAN000306939.

摘要

At the request of the Montgomery County Health Department (MCHD) and the Pennsylvania Department of Environmental Protection (PADEP), the Pennsylvania Department of Health (PADOH), under a cooperative agreement with the Agency for Toxic Substances and Disease Registry (ATSDR), evaluated environmental data on the post-filter residential water samples. In 1999, the MCHD discovered a groundwater contaminant plume when they sampled residential wells in the area. The site has contaminated 17 residential drinking water wells, including a common well that serves 11 residences. The source of contamination is not fully determined. The EPA listed the Baghurst Drive site on the National Priorities List (NPL) in 2014 and is currently providing bottled water to affected residences for drinking and cooking, as well as maintaining carbon filtration systems. The purpose of this health consultation is to review post-filtered water sample data, including 1,4-dioxane, to determine whether the action taken by PADEP is protective of the health of the residents near the Baghurst Drive site who use contaminated well water for showering and bathing. Ingestion is not currently a completed exposure pathway because bottled water is provided for drinking and cooking, thus we did not evaluate the possible health risks from drinking the filtered water.
