Read this first

  • PFNA (above the health goal) was found in one of 10 samples, highest 73.3 ppt. Above the 10 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • PFOA (above the health goal) was found in two of 10 samples, highest 14.4 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • PFOS (above the health goal) was found in two of 10 samples, highest 8.9 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 2.4 ppm, above the 1.3 ppm action level.
  • Lithium (above EPA’s health benchmark) was found in two of 10 samples, highest 12 ppb. Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.

No health-based violations on file since 2016.

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.

PFNA (above the health goal)

Comes from the source

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

Highest of 10 samples; found in one

Above the 10 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.

What handles it

  • NSF/ANSI 53Look for: Total PFAS ReductionSame claim, other certifiers’ wording: Perfluorononanoic Acid (PFNA)

NSF’s PFAS claims are tested to below 20 ppt. EPA’s limit is 10 ppt, and EPA says no certification yet shows a filter reaching its levels.

EPA UCMR 5, samples taken on Feb. 19, 2025. Each blue tick is one sample where it was found.

PFOA (above the health goal)

Comes from the source

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

Highest of 10 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

  • NSF/ANSI 53Look for: PFOA ReductionSame claim, other certifiers’ wording: Total PFAS Reduction; Perfluorooctanoic Acid (PFOA)
  • NSF/ANSI 58Look for: Perfluorooctanoic Acid (PFOA)

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.

EPA UCMR 5, samples taken from Feb. 19, 2025 to Aug. 12, 2025. Each blue tick is one sample where it was found.

PFOS (above the health goal)

Comes from the source

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

Highest of 10 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

  • NSF/ANSI 53Look for: PFOS ReductionSame claim, other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS)
  • NSF/ANSI 58Look for: Perfluorooctane Sulfonate (PFOS)

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.

EPA UCMR 5, samples taken from Feb. 19, 2025 to Aug. 12, 2025. Each blue tick is one sample where it was found.

Copper (above the health goal)

Comes from pipes, often your own

2.4 (above the action level)ppm

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 2.4 ppm, above the 1.3 ppm action level.

What handles it

EPA SDWIS, lead and copper monitoring periods ending 2024. The pointer marks the latest period; each blue tick is an earlier one.

12ppb

Highest of 10 samples; found in two

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.

EPA UCMR 5, samples taken from Feb. 19, 2025 to Aug. 12, 2025. Each blue tick is one sample where it was found.

Lead (above the health goal)

Comes from pipes, often your own

4.0ppb

90th percentile, 2026

In the latest period, 9 in 10 homes sampled were at or below 4.0 ppb, below the 15 ppb action level. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

EPA SDWIS, lead and copper monitoring periods ending 2012 to 2026. The pointer marks the latest period; each blue tick is an earlier one.

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 Feb. 19, 2025 to Jan. 7, 2026. Not found means not measured above that level, which is not the same as zero.

Violations since 2016

No health-based violations on file with EPA since 2016.

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: Total PFAS Reduction, PFOA Reduction, PFOS Reduction, Copper Reduction, Lead Reduction

    For: PFNA, PFOA, PFOS, Copper, Lead

  • NSF/ANSI 58

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

    For: PFOA, PFOS, Copper, Lead

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 East Greenwich Twp Water 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 Feb. 19, 2025 to Jan. 7, 2026.

What to do next

  1. Read up on the 6 marked results

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

    Start with PFNA

  2. Get the utility’s own report

    East Greenwich Twp Water Dept must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.

    How to read it

  3. Test your own tap for lead

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