Benner Township HSCA Investigation


On June 28, 2022, the Department of Environmental Protection (DEP), is holding a public hearing to provide residents of Benner Township with information of the prompt interim response, consisting of provision of bottled drinking water, being implemented for this site. DEP will also receive public comments on its proposed prompt interim response action of installation of whole-house filtration systems on private residential water supplies with combined concentrations of PFOS and PFOA exceeding the United States Environmental Protection Agency (EPA) health advisory level (HAL) of 70 parts per trillion (ppt). Prior to the hearing, DEP will give a brief presentation updating our progress to date.

For more information, please see the Public Meeting Notice or the Pennsylvania Bulletin.

DEP’s Bureau of Environmental Cleanup and Brownfields is investigating a groundwater plume located in Benner Township, Centre County, in accordance with the Hazardous Sites Cleanup Act (HSCA). Periodic updates about this investigation will be posted on this page.

The current Benner Township investigation began in 2020 in response to sampling data from public water supply wells collected by DEP’s Safe Drinking Water Program in 2019. This sampling was conducted in accordance with Pennsylvania’s PFAS Action Team’s Actions and Recommendations included in their 2019 Initial Report. This data indicated that groundwater in the vicinity of High Tech Road is contaminated with per- and poly-fluoroalkyl substance (PFAS) compounds.

The goals of the current HSCA investigation are to delineate the extent of contamination in order to identify any exposure pathways to residents or the environment in the area, to locate potential sources, and to determine possible mitigation or remediation measures.

For more information on PFAS compounds, please see the web links below. For more information about the HSCA program, visit DEP’s HSCA Annual Report Story Map and the HSCA home page.
