Removal Of PFAS Contamination In Horsham Township, PA, Water Supply

In 2016, community pressure for non-detectable levels of perfluoroalkyl substances (PFAS) in potable water forced a shift beyond standard federal advisories. To address contamination effectively, a rigorous investigation compared traditional granular activated carbon (GAC) against PFAS-selective ion exchange resin. The resulting pilot study revealed that utilizing resin—either as a standalone treatment or a polisher—offered significant capital and operating expense advantages.

By integrating this advanced technology into existing systems, providers can achieve high-resolution filtration that traditional methods may struggle to maintain over long-term bed exhaustion. This multi-stage approach allowed for the successful return of critical wells to full service while ensuring a resilient supply of treated water. Ongoing monitoring and strategic lead-lag configurations now serve as a blueprint for cost-effective remediation in complex environmental landscapes.
