Read this first

  • PFOA (above the health goal) was found in three of 4 samples, highest 36 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 three of 4 samples, highest 14 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • PFNA (above the health goal) was found in three of 4 samples, highest 20 ppt. Above the 10 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.

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

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

Highest of 4 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

  • 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 March 5, 2025 to Oct. 22, 2025. Each blue tick is one sample where it was found.

PFOS (above the health goal)

Comes from the source

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

Highest of 4 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

  • 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 March 5, 2025 to Oct. 22, 2025. Each blue tick is one sample where it was found.

PFNA (above the health goal)

Comes from the source

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

Highest of 4 samples; found in three

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 from March 5, 2025 to Oct. 22, 2025. Each blue tick is one sample where it was found.

PFHxS

Comes from the source

5.1ppt

Highest of 4 samples; found in two

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 from March 5, 2025 to Oct. 22, 2025. Each blue tick is one sample where it was found.

PFBS

Comes from the source

7.5ppt

Highest of 4 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 March 5, 2025 to Oct. 22, 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 March 5, 2025 to Oct. 22, 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.

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, PFOS Reduction, Total PFAS Reduction

    For: PFOA, PFOS, PFNA

  • NSF/ANSI 58

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

    For: PFOA, PFOS

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 Georgetown Water Department’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 March 5, 2025 to Oct. 22, 2025.

What to do next

  1. Read up on the 3 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

    Georgetown Water Department 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
