In May 2016, as a result of the Environmental Protection Agency (EPA) lowering the health advisory level of the unregulated contaminants perfluorooctanoic acid (PFOA) and perfluoro-octanesulfonate (PFOS) to 70 parts per trillion (ppt) the Doylestown Township Municipal Authority (DTMA) closed the public Cross Keys Well after sampling revealed levels above the EPA’s health advisory level. In addition, DTMA initiated a sampling program at all of their other public wells. This sampling revealed the remaining wells have detectable levels of PFOA and PFOS. However, these levels are well below the new health advisory level and the water is considered safe for consumption. DTMA will continue to monitor and sample all their wells in the future for these contaminants. Also, the Pennsylvania Department of Environmental Protection (DEP) continues to conduct their sampling program within a one mile radius of the Cross Keys well for Doylestown Township residents with private wells.
As a result of the Cross Keys public well closure, the DTMA began using a temporary, backup source of water. In the meantime, DTMA began investigating cost effective alternatives to find a permanent source. It was determined a water main extension from Sawmill Road and Swamp Road connecting DTMA’s North Water System to the Cross Key System will provide with a safe, reliable supply of water for years to come.
Since May 2016 the Pennsylvania Department of Environmental Protection ( PA DEP) has been actively investigating PFOA/PFOS contamination within the Doylestown area as part of the Easton Road PFC HSCA site.
DEP’s next step in this investigation involves the construction and installation of groundwater monitoring wells in the site area, specifically within an area of Doylestown Township where the highest concentrations of PFOA/PFOS have been encountered. The purpose of these monitoring wells is to aid the PA DEP in determining the nature and extent of groundwater contamination beneath the site area. This information will also assist PA DEP in drafting a potential interim response action to be implemented at the site.
