Read this first

  • PFOA (above the health goal) was found in one of 16 samples, highest 6.5 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • Lead (above the health goal) In the latest period, 9 in 10 homes sampled were at or below 1.0 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.

3 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.

PFOA (above the health goal)

Comes from the source

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

Highest of 16 samples; found in one

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 on Sept. 23, 2025. Each blue tick is one sample where it was found.

Lead (above the health goal)

Comes from pipes, often your own

1.0ppb

90th percentile, 2023 to 2025

In the latest period, 9 in 10 homes sampled were at or below 1.0 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 2004 to 2025. The pointer marks the latest period; each blue tick is an earlier one.

PFBS

Comes from the source

16.9ppt

Highest of 16 samples; found in two

Below EPA’s hazard index benchmark of 2,000 ppt. PFBS has no legal limit or health goal of its own.

What handles it

EPA UCMR 5, samples taken from Dec. 19, 2024 to Sept. 23, 2025. Each blue tick is one sample where it was found.

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. 19, 2024 to Sept. 23, 2025. 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, Lead Reduction

    For: PFOA, Lead

  • NSF/ANSI 58

    Claims: Perfluorooctanoic Acid (PFOA), Lead Reduction

    For: PFOA, 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 Wilson Co Water & Wastewater’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. 19, 2024 to Sept. 23, 2025.

What to do next

  1. Read up on the 2 marked results

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

    Start with PFOA

  2. Get the utility’s own report

    Wilson Co Water & Wastewater 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.
