From EPA SDWIS. Counted once per contaminant per year, as in the Track record score.
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.

Questions
Frequently asked questions
Who does SOUTH RIVER W DEPT serve?
SOUTH RIVER W DEPT (PWS ID NJ1223001) is a public water system serving 16,000 people in South River, New Jersey.
Where does SOUTH RIVER W DEPT get its water?
SOUTH RIVER W DEPT is on record as drawing from surface water. The source shapes which contaminants matter most for this system.
What does SOUTH RIVER W DEPT's monitoring record show?
PurityMap's record for SOUTH RIVER W DEPT holds 32 findings: 4 above a reference, 1 detected within the reference, 2 detected with no limit and 25 not detected, from 32 evidence records. Every finding links to its source; a substance that was never monitored is shown as pending, not as a pass.
Is SOUTH RIVER W DEPT's water safe to drink?
PurityMap does not issue a safety verdict. It publishes SOUTH RIVER W DEPT'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 SOUTH RIVER W DEPT data?
The latest published record for SOUTH RIVER W DEPT 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 SOUTH RIVER W DEPT'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 SOUTH RIVER W DEPT?
Perfluorooctanoic acid (PFOA), Lithium, Copper (90th percentile), Perfluorooctanesulfonic acid (PFOS), 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 SOUTH RIVER W DEPT'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.
