Read this first

  • PFOA (above the health goal) was found in three of 6 samples, highest 7.6 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • Copper (above the health goal) In the latest period, 9 in 10 homes sampled were at or below 1.8 ppm, above the 1.3 ppm action level.
  • PFOS (above the health goal) was found in two of 6 samples, highest 4.1 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • Lithium (above EPA’s health benchmark) was found in one of 6 samples, highest 15.1 ppb. Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.

4 health-based violations since 2016. Details are below.

What handles it

What was found

Highlighted: above the health goal, or EPA’s health benchmark where there is no goal. Circled: above the legal limit in at least one sample, or the action level. Every scale puts that line at its middle.

PFAS and lithium: EPA UCMR 5, samples taken from Dec. 14, 2023 to Sept. 16, 2024. Each blue tick on a scale is one sample where it was found.

Lead and copper: EPA SDWIS monitoring periods ending 1992 to 2022. The pointer marks the latest period; each blue tick is an earlier one.

NSF’s PFAS claims are tested to below 20 ppt. EPA’s limit is 4.0 ppt, and EPA says no certification yet shows a filter reaching its levels.

PFOA (above the health goal)

Comes from the source

7.6 (above the legal limit in at least one sample)ppt

Highest of 6 samples; found in three

Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.

What handles it

Copper (above the health goal)

Comes from pipes, often your own

1.8 (above the action level)ppm

90th percentile, 2022

In the latest period, 9 in 10 homes sampled were at or below 1.8 ppm, above the 1.3 ppm action level.

What handles it

PFOS (above the health goal)

Comes from the source

4.1 (above the legal limit in at least one sample)ppt

Highest of 6 samples; found in two

Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.

What handles it

15.1ppb

Highest of 6 samples; found in one

Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.

What handles it

No certification claim covers this compound yet.

Also found, with no federal limit

EPA measured these PFAS to learn how often they occur. None has a legal limit or a health goal yet.

Tested and not found

Below EPA’s minimum reporting level in every sample taken from Dec. 14, 2023 to Sept. 16, 2024. Not found means not measured above that level, which is not the same as zero.

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: PFOA Reduction, Copper Reduction, PFOS Reduction

    Other certifiers’ wording: Total PFAS Reduction; Perfluorooctanoic Acid (PFOA); Perfluorooctane Sulfonate (PFOS)

    For: PFOA, Copper, PFOS

  • NSF/ANSI 58

    Claims: Perfluorooctanoic Acid (PFOA), Copper Reduction, Perfluorooctane Sulfonate (PFOS)

    For: PFOA, Copper, PFOS

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 cannot tell you

  • Levels of everything else. Federal bulk data carries results for PFAS, lithium, lead and copper, and violations for the rest. Nitrate, arsenic, disinfection byproducts and other levels are in South River W Dept’s own annual report, which it must send you every year.
  • 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.
  • Anything after the latest data. SDWIS data is from 2026 Q2; UCMR 5 samples are from Dec. 14, 2023 to Sept. 16, 2024.

  • Read up on the 4 marked results

    What each one does to health, where it comes from, and the certification claim that addresses it.

    Start with PFOA

  • Get the utility’s own report

    South River W Dept must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.

    How to read it

  • Test your own tap for lead

    Your service line, solder and fixtures decide the lead at your faucet, not the utility’s average.
