The short answer

2 results are above EPA’s legal limit, and 1 more is above the health goal. The worst: Copper, above the action level. 28 health-based violations since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1995 to 2024.

Nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and uranium: New Jersey’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from Feb. 16, 2012 to Jan. 9, 2018. Newer results are in the utility’s annual water quality report.

Above the legal limit2

Copper

Comes from pipes, often your own

Above the action level

3.8ppm

90th percentile, 2024

In the latest period, 9 in 10 homes sampled were at or below 3.8 ppm, above EPA’s action level of 1.3 ppm.

What handles it

Nitrate

Comes from the source

Above the legal limit

3.9ppm

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 3.9 ppm, in 2023, below EPA’s legal limit of 10 ppm. That was also the latest year on file. EPA judges this limit at each sampling point, and recorded violations for nitrate at this utility in 2023 and 2024. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 21 ppm, in 2012, and EPA recorded violations in 2012 and 2018.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Above the health goal1

Lead

Comes from pipes, often your own

Above the health goal

3.8ppb

90th percentile, 2026

In the latest period, 9 in 10 homes sampled were at or below 3.8 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

Below EPA’s limits

35ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 35 ppb, in 2023, below EPA’s legal limit of 80 ppb. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.7 ppb, in 2019.

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claims: Copper Reduction, Nitrate/Nitrite (30 ppm challenge), Lead Reduction

    For: Copper, Nitrate, Lead

  • NSF/ANSI 58

    Claims: Copper Reduction, Nitrate/Nitrite Reduction, Lead Reduction

    For: Copper, Nitrate, Lead

    Other certifiers’ wording: Nitrate

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report can’t tell you

  • Everything else. Nitrate, total trihalomethanes (TTHM), haloacetic acids (HAA5), arsenic and uranium results here are New Jersey’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Big Oak Rehab’s own annual report, which it must send you every year, has newer results for those and the contaminants this page does not show.

  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; CDC’s yearly averages for New Jersey cover 2020 to 2023; EPA’s compliance samples are from Feb. 16, 2012 to Jan. 9, 2018.

Testing your own tap

Big Oak Rehab’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab New Jersey certifies.
