One PFAS above the 2024 federal limit

The bar is drawn in blocks of the 4.0 ng/L federal MCL (2024), so the length shows how far above it the result sits.

Compliance

0health-based violations in the last 10 years

From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

Not in this recordDisinfection by-products weren't monitored in this dataset

No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.

A federal limit (an MCL or action level) is an enforceable legal cap; a health goal is often stricter. Meeting the limit is a compliance fact, not a health clearance, and PurityMap publishes no overall compliance verdict.

Commercial

Certified for a concern found here

Each card names which of this system’s findings its current certification covers, and which it doesn’t.

As an Amazon Associate, PurityMap earns from qualifying purchases. A product appears here only when a current certification record covers at least one identified concern; every concern stays listed. The retail offer is looked up afterwards and never changes which products appear or their order. Affiliate disclosure.

Questions

Frequently asked questions

Who does RAHWAY WATER DEPARTMENT serve?

RAHWAY WATER DEPARTMENT (PWS ID NJ2013001) is a public water system serving 27,300 people in Rahway, New Jersey.

Where does RAHWAY WATER DEPARTMENT get its water?

RAHWAY WATER DEPARTMENT is on record as drawing from surface water. The source shapes which contaminants matter most for this system.

What does RAHWAY WATER DEPARTMENT's monitoring record show?

PurityMap's record for RAHWAY WATER DEPARTMENT holds 31 findings: 1 above a reference, 1 detected within the reference, 2 detected with no limit and 27 not detected, from 31 evidence records. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.

Is RAHWAY WATER DEPARTMENT's water safe to drink?

PurityMap does not issue a safety verdict. It publishes RAHWAY WATER DEPARTMENT's measured results against each contaminant's benchmark so you can read them in context. Safety depends on the specific finding, your plumbing, and how the water reaches your tap.

How current is this RAHWAY WATER DEPARTMENT data?

The latest published record for RAHWAY WATER DEPARTMENT is dated 2026-09-16. Utilities report on regulatory cycles, so results reflect the monitoring period rather than a live reading.

Does this assessment represent my home's tap water?

No. It is assessed at the water-system level from RAHWAY WATER DEPARTMENT's own monitoring. It does not cover the service line to your building or the plumbing inside it, which can add lead and other metals after the water leaves the system. A tap test is the way to know what reaches your glass.

What contaminants were detected in RAHWAY WATER DEPARTMENT?

Perfluorooctanoic acid (PFOA), Perfluorohexanoic acid (PFHxA), Perfluorobutanoic acid (PFBA) and Perfluoropentanoic acid (PFPeA) were detected in this record. Each finding shows its measured value, its reference and its source on this page.

What should I do if I'm concerned about PFAS in RAHWAY WATER DEPARTMENT's water?

Start with what the record shows: the PFAS findings above list each measured value against its reference. This record cannot show your home's plumbing, so a tap test tells you what reaches your glass. If you decide to treat your water, look for a filter whose certification covers the specific PFAS compounds in your record; the section "Certified for a concern found here" lists only products with a current certification record for these concerns.
