PWSID PA1090081 · EPA data

Read this first

  • PFOA (above the health goal) was found in 10 of 10 samples, highest 14.6 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 10 of 10 samples, highest 11.3 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 1.6 ppm, above the 1.3 ppm action level.

No health-based violations on file since 2016. EPA lists 31 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.

PFAS and lithium: EPA UCMR 5, samples taken from April 22, 2025 to Oct. 28, 2025. Each blue tick on a scale is one sample where it was found.

Lead and copper: EPA SDWIS monitoring periods ending 1996 to 1999. The pointer marks the latest period; each blue tick is an earlier one.

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.

PFOA (above the health goal)

Comes from the source

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

Highest of 10 samples; found in 10

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

PFOS (above the health goal)

Comes from the source

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

Highest of 10 samples; found in 10

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

Copper (above the health goal)

Comes from pipes, often your own

1.6 (above the action level)ppm

90th percentile, 1999

In the latest period, 9 in 10 homes sampled were at or below 1.6 ppm, above the 1.3 ppm action level.

What handles it

PFHxS

Comes from the source

6.4ppt

Highest of 10 samples; found in six

Detected, below the legal limit and the health goal.

What handles it

PFNA

Comes from the source

5.2ppt

Highest of 10 samples; found in three

Detected, below the legal limit and the health goal.

What handles it

PFBS

Comes from the source

7.5ppt

Highest of 10 samples; found in 10

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

What handles it

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 April 22, 2025 to Oct. 28, 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 31 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.”

  • NSF/ANSI 53

    Claims: PFOA Reduction, PFOS Reduction, Copper Reduction

    Other certifiers’ wording: Total PFAS Reduction; Perfluorooctanoic Acid (PFOA); Perfluorooctane Sulfonate (PFOS)

    For: PFOA, PFOS, Copper

  • NSF/ANSI 58

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

    For: PFOA, PFOS, Copper

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 Doylestown Boro 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 April 22, 2025 to Oct. 28, 2025.

  • Get the utility’s own report

    Doylestown Boro 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

  • Test your own tap for lead

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