PFAS in Ridgewood’s Water — Why the Hackensack Watershed Makes This Question More Relevant Than Most Bergen County Homeowners Realize
The Hackensack River watershed — which supplies Ridgewood’s municipal water through Suez Water — has a documented PFAS contamination history from industrial discharge and AFFF firefighting foam use at facilities throughout Bergen County and the broader watershed. Suez Water tests and treats for PFAS under New Jersey’s strict regulatory framework. But for Ridgewood homeowners who want property-specific certainty beyond system-level reporting, or for anyone in the area on a private well where no regulatory protection applies, understanding the PFAS picture in this watershed requires more than a passing look at the annual consumer confidence report. This page explains what PFAS are, how they may be present in Ridgewood area water, and what options exist for addressing them.
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 bond gives PFAS commercial value and 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 at health-relevant concentrations. 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 Reached the Hackensack Watershed
The Hackensack River watershed spans Bergen County and portions of surrounding counties — an area with a substantial industrial and aviation history. Manufacturing facilities that used PFAS-containing compounds in coating, chemical processing, and consumer product production have contributed to watershed PFAS loading through discharge and waste handling. Aqueous film-forming foam (AFFF) used at military installations, airports, and industrial emergency response training sites throughout the region has produced PFAS plumes that spread through soil into groundwater and surface water without respecting property or municipal boundaries.
Suez Water has implemented treatment improvements targeting PFAS in response to New Jersey’s strict regulatory requirements. New Jersey’s maximum contaminant levels for PFOA, PFOS, PFNA, and GenX are among the strictest state standards in the country. Annual consumer confidence reports reflect where the treated supply stands against those limits. The NJDEP PFAS resources page provides current contamination site and monitoring data.
Municipal Water vs. Private Wells
Ridgewood’s municipal customers have meaningful regulatory protection through Suez Water’s mandatory testing, NJ MCL compliance, and public reporting. Private well owners anywhere in Bergen County — less common in Ridgewood’s established residential areas but present in portions of the broader county — have no equivalent protection. Bergen County’s partially crystalline geology means groundwater can carry both naturally occurring and industrially sourced PFAS. Testing is the homeowner’s responsibility and the only reliable approach for establishing what a specific well contains.
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 Ridgewood’s Water Context
| Contaminant | Source Relevant to Ridgewood | Detection | Why It Matters |
|---|---|---|---|
| PFAS (broad) | Hackensack watershed industrial discharge, AFFF | Specific lab test — no sensory indicator | Persistent; long-term exposure concern |
| PFOA | Manufacturing runoff in Bergen County region | PFAS panel lab test | NJ MCL established; most studied compound |
| PFOS | AFFF at aviation and military sites in watershed | PFAS panel lab test | Documented contamination plumes in Bergen County |
| 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 Ridgewood water quality picture, water testing in Ridgewood covers the complete contaminant profile.

Frequently Asked Questions — PFAS in Ridgewood, NJ Drinking Water
Has PFAS been detected in the Hackensack watershed that supplies Ridgewood?
Yes — PFAS has been documented in the Hackensack River watershed from industrial and AFFF sources. Suez Water 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 Ridgewood address.
Does Ridgewood’s soft water affect how PFAS behaves in the supply?
Water softness doesn’t directly affect PFAS concentrations — PFAS comes from industrial and environmental sources rather than from the geological chemistry that determines water hardness. However, Ridgewood’s soft, slightly acidic water does make reverse osmosis a particularly well-suited household treatment option, as it addresses PFAS, lead from corrosion in older plumbing, and copper dissolution simultaneously.
Is PFAS testing included in a standard water quality panel?
No. It must be specifically requested as a separate laboratory analysis. Standard panels don’t include PFAS unless explicitly ordered.
What treatment addresses both PFAS and the corrosion-related metal concerns in Ridgewood’s older homes?
Reverse osmosis at the kitchen tap addresses both — it removes PFAS to high efficiency and removes dissolved copper and lead from corrosion in the home’s interior plumbing. For Ridgewood homeowners in pre-1986 construction where soft water corrosivity is an ongoing concern, reverse osmosis with a remineralization stage addresses the full range of drinking water concerns simultaneously.
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.
