Clean, Safe Water for Homes with a Legacy of Groundwater Concerns
Havertown, part of Haverford Township, is a vibrant Delaware County community known for its tree-lined neighborhoods, close-knit feel, and proximity to Philadelphia. But for many residents, Havertown’s history includes a more sobering reality — the Havertown PCP Superfund Site, a 13-acre area where decades of industrial waste disposal contaminated nearby groundwater and Naylors Run with arsenic, VOCs, dioxins, and more.

Although remediation efforts have significantly reduced risks, monitoring continues, and modern contaminants like PFAS (“forever chemicals”) remain a growing concern for private well owners and public-water households alike.
At Dierolf Plumbing & Water Treatment, we combine deep local knowledge with advanced testing and treatment solutions to protect your family, your plumbing, and your peace of mind.
Why Havertown’s Water Quality Gets Extra Attention
- Superfund Legacy: From 1947–1991, the former National Wood Preservers site discharged pollutants into the environment, impacting groundwater quality in parts of Havertown. (EPA/Havertown PCP Site Overview)
- PFAS in the Region: Statewide studies, including southeastern PA, show 18% of private wells exceed safe PFAS levels. (WHYY coverage)
- Well & Aging Infrastructure Risks: Homes with private wells — and even those on public supply — face risks from corrosion, sediment, and bacterial intrusion.
Common Water Challenges in Havertown
