Summit Homeowners Apply Rigorous Standards to Every Decision. PFAS Testing Should Be No Exception.
PFAS — per- and polyfluoroalkyl substances — have been detected in portions of New Jersey’s water supply system, and the Raritan River basin that supplies Summit through New Jersey American Water has documented contamination from industrial sources throughout Central New Jersey. For Summit municipal customers, NJAW tests and reports PFAS against New Jersey’s strict state MCLs. But for homeowners who want property-level certainty rather than system-level assurance — and for anyone in Union County on a private well where no regulatory protection applies — testing the tap directly provides the most relevant answer. This page explains what PFAS are, how they may be present in Summit area water, and what homeowners can do.
What PFAS Are
Per- and polyfluoroalkyl substances — PFAS — are a category of more than 12,000 synthetic chemical compounds defined by an extremely strong carbon-fluorine bond that makes them environmentally permanent. They don’t break down under heat, UV light, biological processes, or water. They have no taste, no smell, and no visual indicator. Standard treatment doesn’t reliably remove them. Activated carbon filtration and reverse osmosis are the established household approaches. The EPA’s PFAS overview provides the full background.
How PFAS May Be Present in Summit Area Water
New Jersey American Water sources from the Raritan River basin — a watershed with documented PFAS contamination from decades of industrial manufacturing activity along the Route 1 corridor and AFFF firefighting foam use at industrial and military facilities throughout Central New Jersey. NJAW tests and treats for PFAS under New Jersey’s regulatory requirements. Annual consumer confidence reports reflect where the treated supply stands against state MCLs. The NJDEP PFAS resources page provides current monitoring data and contamination site information relevant to Union County and the Raritan watershed.
For Union County private well owners — less common in Summit’s residential core but present in portions of the surrounding area — no regulatory monitoring applies. PFAS from industrial sources in the Raritan Basin can migrate through aquifer systems to reach private wells at variable concentrations depending on location and groundwater flow. Testing is the homeowner’s responsibility and the only reliable approach.
Health Considerations
Long-term exposure to elevated PFAS has been associated with immune system effects, thyroid hormone disruption, cholesterol changes, and increased cancer risk with prolonged exposure. These are long-term cumulative effects — not acute reactions. Accurate measurement followed by informed treatment decisions when levels warrant it is the appropriate response. The CDC’s PFAS health guidance provides regularly updated research summaries.
PFAS in Summit’s Water Context
| Contaminant | Source Relevant to Summit | Detection | Why It Matters |
|---|---|---|---|
| PFAS (broad) | Raritan Basin industrial discharge, AFFF | Specific lab test — no sensory indicator | Persistent; long-term exposure concern |
| PFOA | Manufacturing runoff throughout Raritan watershed | PFAS panel lab test | NJ MCL established; most studied compound |
| PFOS | AFFF at industrial and military facilities | PFAS panel lab test | Significant plumes in Central NJ groundwater |
| PFNA, GenX | Industrial substitutes and byproducts | Comprehensive PFAS panel | NJ has specific MCLs for both |
Testing and Treatment
PFAS testing requires a specific laboratory analysis — not included in standard water quality panels, must be explicitly ordered. Results in parts per trillion are compared against New Jersey’s MCLs. If levels warrant action, whole-home activated carbon filtration and reverse osmosis at the kitchen tap are the most effective household approaches. Full treatment detail is available through our PFAS removal resources. For the full Summit water quality picture, water testing in Summit covers the complete contaminant profile.

Frequently Asked Questions — PFAS in Summit, NJ Drinking Water
Has PFAS been detected in Summit’s water supply?
The Raritan Basin has documented PFAS contamination from industrial sources. NJAW tests and reports against New Jersey’s strict MCLs. Whether PFAS is above action levels in the current treated supply is reflected in the annual consumer confidence report. A direct tap test provides the most property-specific answer at a specific Summit address.
Is PFAS testing included in a standard water quality panel?
No. PFAS requires a specific laboratory analysis ordered separately. Standard panels don’t include PFAS. If it wasn’t explicitly ordered in a previous test, the question remains open.
Should I test for both PFAS and lead in my older Summit home?
Yes — they’re separate concerns requiring separate tests. Lead comes from interior plumbing. PFAS comes from environmental and industrial sources in the water supply. A comprehensive tap-level water test can address both simultaneously, giving you the complete picture for your specific home.
What’s the most effective treatment for PFAS at the kitchen tap?
Reverse osmosis is the most effective household-level technology. For Summit homeowners with both PFAS concerns and metallic taste from older plumbing, reverse osmosis addresses both simultaneously. System selection depends on specific compounds and concentrations found in testing.
How long does PFAS testing take?
Sample collection takes under an hour. Lab results typically return within two to three weeks. We review what the results mean and discuss appropriate options when they come back.
