Description:Prepared by Pennsylvania Department of Health Division of Environmental Health Epidemiology Under a Cooperative Agreement with the Agency for Toxic Substances and Disease Registry.
In response to the BoRit asbestos site (‘the site’) being listed on the Environmental Protection Agency (EPA) National Priorities List (NPL) and EPA’s collection of environmental sampling data as part of the site Remedial Investigation/Feasibility Study (RI/FS), the Pennsylvania Department of Health (PADOH) prepared this Public Health Assessment (PHA) document. PADOH’s primary goal is to evaluate whether a community is being exposed to levels of contaminants that may harm their health and make any necessary recommendations to prevent and mitigate exposures, as well as to ensure that the community has the best information possible to protect public health. PADOH worked under a cooperative agreement with the Agency for Toxic Substances and Disease Registry (ATSDR) to complete this PHA document.
PADOH evaluated air sampling and soil data for asbestos, collected at both on- site and off-site locations. As part of the removal activities and the RI/FS, EPA collected ambient air samples for asbestos, as well as activity-based sampling (ABS), to determine the potential exposure levels to asbestos in the air during vigorous activities such as lawn raking, children outdoors playing while lawn maintenance occurs, jogging, disturbing site soils and potential trespassing on the site itself. Using the air sampling data, PADOH assessed potential cancer risk for inhalation exposures to asbestos, on and off the BoRit site. PADOH also reviewed on-site soil and adjacent surface water data collected for asbestos. Lastly, PADOH compiled health outcome data, from the Pennsylvania Cancer Registry, for the Ambler community. The purpose of this PHA is to provide a summary of PADOH’s review, answer community concerns, and provide relevant public health findings and recommendations. The public comment period for the PHA was from July 25, 2013 through September 30, 2013. After reviewing the comments and incorporating any changes or revisions, this version of the PHA now reflects PADOH’s final conclusions and recommendations for the BoRit site, based on the information available about the site at this time.
