PWSID VA3710100 · EPA data

Read this first

  • PFOS was found in one of 8 samples, highest 5.8 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.

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, stop by stop

  • Below the health goal
  • Above the health goal
  • Above the legal limit
  • No federal data

  1. At the source

    EPA UCMR 5 sampled this utility for 29 PFAS and lithium from Feb. 13, 2023 to Jan. 9, 2024. Each tick under a result’s line is one sample where it was found, dated when you point at it.

    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.

  2. PFOS

    Above the legal limit

    5.8ppt

    Highest of 8 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.

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

    • NSF/ANSI 58 · Look for: Perfluorooctane Sulfonate (PFOS)

  3. 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.

  4. In treatment

    No federal results for this stop. Disinfection byproduct, chlorine and fluoride levels are in City of Norfolk’s own annual report, which it must send you every year.

  5. In the pipes

    No lead and copper results on file with EPA for this utility.

  6. At your tap

    The last stretch is your own plumbing. A certified lab test is the only way to know what reaches your glass. Lead in your water: what to do

Tested and not found

Below EPA’s minimum reporting level in every sample taken from Feb. 13, 2023 to Jan. 9, 2024. 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?

These come with the water itself, so a whole-house system certified for the same claims treats every tap and shower. A filter at the tap treats drinking water for much less. 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 Norfolk’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. 13, 2023 to Jan. 9, 2024.

What to do next

  1. About PFOS

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

  2. Read the utility’s own report

    City of Norfolk must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.

  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 five-year costs

    What the filters certified for these results cost over five years, cartridges included.
