Read this first

  • Copper (above the health goal) In the latest period, 9 in 10 homes sampled were at or below 1.4 ppm, above the 1.3 ppm action level.

No health-based violations on file since 2016. EPA lists 2 monitoring or reporting violations, which are paperwork and testing lapses rather than water quality findings.

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.

Copper (above the health goal)

Comes from pipes, often your own

1.4 (above the action level)ppm

90th percentile, 2020

In the latest period, 9 in 10 homes sampled were at or below 1.4 ppm, above the 1.3 ppm action level.

What handles it

EPA SDWIS, lead and copper monitoring periods ending 1992 to 2020. The pointer marks the latest period; each blue tick is an earlier one.

PFHxS

Comes from the source

3.0ppt

Highest of 2 samples; found in one

Detected, below the legal limit and the health goal.

What handles it

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

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. 11, 2025. Each blue tick is one sample where it was found.

PFBS

Comes from the source

3.5ppt

Highest of 2 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 Feb. 11, 2025 to Aug. 13, 2025. Each blue tick is one sample where it was found.

Tested and not found

Below EPA’s minimum reporting level in every sample taken from Feb. 11, 2025 to Aug. 13, 2025. 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. There are 2 monitoring or reporting violations: a sample missed, late or not reported.

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.”

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 City of Charlotte’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. 11, 2025 to Aug. 13, 2025.

What to do next

  1. Read up on Copper

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

    About Copper

  2. Get the utility’s own report

    City of Charlotte 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.

  4. Compare certified filters
