Your Local Experts in Montgomery & Bucks Counties
Telford, which straddles both Montgomery and Bucks counties, is a vibrant, growing community with a mix of public water systems and private wells. Like many towns in the region, water quality is a top priority for residents—and recent reports have brought attention to the importance of home filtration and testing.
The Telford Borough Authority provides water to most of the area, and while the water meets federal standards, local and national health organizations have flagged concerns:
  • The Environmental Working Group (EWG) identified elevated levels of arsenic and disinfection byproducts like trihalomethanes (TTHMs), which exceed EWG’s stricter health guidelines.
  • PFAS chemicals—also known as “forever chemicals”—have been detected in multiple local wells.
  • In response, the borough received a $9.8 million grant to install Granular Activated Carbon (GAC) treatment systems to reduce PFAS at five well stations.
Telford residents also deal with hard water, commonly ranging from 6–9 grains per gallon (GPG), which can cause scale buildup in pipes and reduce the efficiency of water heaters and other appliances.
