The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. 5 health-based violations since 2016.

What handles it

What was found

PFAS: Pennsylvania’s own results under its PFAS rule, entry point samples taken from March 14, 2025 to Sept. 10, 2026.

Arsenic, nitrate, fluoride, chromium (total), haloacetic acids (HAA5), total trihalomethanes (TTHM) and uranium: Pennsylvania’s own results, samples taken from Jan. 9, 2020 to April 9, 2026, with EPA’s 2012 to 2019 file for earlier years.

PFAS: PFOA and PFBS were found, of the six PFAS in EPA’s 2024 drinking water rule; their results are below. Three other PFAS with no federal limit were found, the highest PFBA at 6.9 ppt: see them below.

Results from Pennsylvania’s own PFAS monitoring, samples where water enters the pipes; each compound’s card has its four-quarter averages, the way limits are judged. The limits are EPA’s 2024 rule, with compliance due from 2029; EPA has since proposed changes to some of them, explained on each compound’s page. Pennsylvania’s own limits for PFOA and PFOS are in force now. PFBS has no limit of its own and counts only toward EPA’s Hazard Index, which TapBuff works out only from UCMR 5’s averages, so it isn’t given here.

About PFAS certifications

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.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

7.0ppb

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 7.0 ppb, in 2024: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That was also the latest year on file.

What handles it

  • NSF/ANSI 58 look for “Arsenic (Pentavalent)<=50 ppb Reduction”
  • NSF/ANSI 53 look for “Arsenic (Pentavalent)<=50 ppb Reduction”

PFOA

Comes from the source

Above the health goal

2.1ppt

Highest sample, Sept. 10, 2026; found in 1 of 5

2026 average: 1.1 ppt

The highest sample was 2.1 ppt: below EPA’s new limit of 4.0 ppt, which takes effect in 2029, but above its health goal of zero. No entry point has four quarters of results in a row to average, the way both Pennsylvania’s limit and EPA’s are judged. In 2026, the latest year on file, its two samples averaged 1.1 ppt.

What handles it

Below EPA’s limits3

Nitrate

Comes from the source

Below EPA’s limits

1.3ppm

Highest sample; found in 7 of 7

2026, one sample: 1.2 ppm

The highest sample, in 2021, was 1.3 ppm, below EPA’s legal limit of 10 ppm. In 2026, the latest year on file, its one sample was 1.2 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 1.5 ppm, in 2013.

What handles it

  • NSF/ANSI 58 look for “Nitrate/Nitrite Reduction”
  • NSF/ANSI 53 look for “Nitrate/Nitrite (30 ppm challenge)”

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.2ppm

Highest yearly average, 2021 to 2024

Averaged by year, the highest was 0.2 ppm, in 2024, below EPA’s legal limit of 4.0 ppm. That was also the latest year on file.

What handles it

PFBS

Comes from the source

Below EPA’s limits

2.3ppt

Highest sample, Oct. 9, 2025; found in 2 of 5

2026 average: 1.1 ppt

The highest sample was 2.3 ppt, below EPA’s hazard index benchmark of 2,000 ppt. PFBS has no legal limit or health goal of its own. In 2026, the latest year on file, its two samples averaged 1.1 ppt.

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.

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: Arsenic (Pentavalent)<=50 ppb Reduction, PFOA Reduction

    For: Arsenic, PFOA

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level); Total PFAS Reduction; Perfluorooctanoic Acid (PFOA)

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Perfluorooctanoic Acid (PFOA)

    For: Arsenic, PFOA

    Other certifiers’ wording: Arsenic (Pentavalent)<=300 ppb Reduction; Arsenic (V) (300 ppb influent level)

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 can’t tell you

  • Everything else. Arsenic, nitrate, fluoride, chromium (total), haloacetic acids (HAA5), total trihalomethanes (TTHM) and uranium results here are Pennsylvania’s own from 2020 on, with EPA’s national file for 2012 to 2019. Cocalico Manor MHP’s own annual report, which it must send you every year, has the contaminants this page does not show.

  • 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.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; Pennsylvania’s results run from Jan. 9, 2020 to April 9, 2026; Pennsylvania’s PFAS results run from March 14, 2025 to Sept. 10, 2026.

Testing your own tap

Cocalico Manor MHP’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab Pennsylvania certifies.
