One or more PFAS compounds exceed EPA Maximum Contaminant Levels. This is not a current violation — the federal compliance deadline is April 2029 (a proposed extension to 2031 is not final). These are UCMR 5 results from 2023 to 2025; the system may have installed treatment since.

Jul 2, 2025 · Aqua Pennsylvania Inc. - Chalfont Well 14 PFAS Project · $1.24M
Listed for FFY2025 BIL Emerging Contaminants funds in the DWSRF Intended Use Plan. Source →
Apr 23, 2025 · Received a $1,244,060 grant and a $655,940 loan for a Per- and Polyfluoroalkyl substances (PFAS) remediation project at the Chalfont Well 14 in New Britain Borough. The existing Chalfont Well 14 Treatment Station treats groundwater from the well. A new treatment facility will be constructed to maintain the permitted capacity of 250 gallons per minute (GPM) and will be located on the property of the existing Chalfont Well 14 Station. The PFAS treatment will involve the usage of ion-exchange units to adsorb the Perfluorooctanesulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) compounds. Two 5-foot diameter treatment vessels will be installed with a 5-micron cartridge filter upstream of the IX system. This project will remove PFAS from the drinking water system. · —
