The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Copper: EPA’s file records a utility’s copper only when it exceeds the action level. The last here was 2.1 ppm, for the period ending Dec. 31, 2019. None since is on file, so it is not counted as a current finding.

Nitrate, arsenic and total trihalomethanes (TTHM): Maine’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Uranium, fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from Jan. 17, 2012 to April 23, 2018. Newer results are in the utility’s annual water quality report.

Above the health goal1

Uranium

Above the health goal

1.3ppb

Highest yearly average, 2014 to 2017

2017: not found

Averaged by year, the highest was 1.3 ppb, in 2014: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2017, the latest year on file, it wasn’t found in its one sample.

Below EPA’s limits

1.0ppm

Highest yearly average, 2012 to 2018

2018 average: 0.44 ppm

Averaged by year, the highest was 1.0 ppm, in 2017, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 4.8 ppm. In 2018, the latest year on file, its four samples averaged 0.44 ppm. EPA recorded no violation for fluoride at this utility from 2012 to 2019.

What handles it

Nitrate

Below EPA’s limits

0.81ppm

Highest yearly average, 2020 to 2023

2023 average: 0.63 ppm

Averaged by year, the highest was 0.81 ppm, in 2021, below EPA’s legal limit of 10 ppm. In 2023, the latest year on file, it averaged 0.63 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.79 ppm, in 2019.

What handles it

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

Chromium (total)

Comes from the source

Below EPA’s limits

1.1ppb

Highest yearly average, 2014 to 2017

2017: not found

Averaged by year, the highest was 1.1 ppb, in 2014, below EPA’s legal limit of 100 ppb. In 2017, the latest year on file, it wasn’t found in its one sample.

What handles it

3 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Lead
  • Total trihalomethanes (TTHM)

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.

Filters with those claims on a certifier’s listing

None of the filters TapBuff has checked so far carry these claims. Search the certifier listings for the claim above.

What this report can’t tell you

  • Everything else. Nitrate, arsenic and total trihalomethanes (TTHM) results here are Maine’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Uranium, fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. South Freeport Water District’s own annual report, which it must send you every year, has newer results for those and 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; CDC’s yearly averages for Maine cover 2020 to 2023; EPA’s compliance samples are from Jan. 17, 2012 to April 23, 2018.

Testing your own tap

South Freeport Water District’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 Maine certifies.

The 3 labs Maine certifies closest to the area South Freeport Water District serves, in a straight line. Call first: certification is test by test, and not every lab takes samples from homeowners.

Maine Health and Environmental Testing Laboratory: Well water test kits ordered online, from a bacteria-only test to full panels for new wells and home sales. The lab must receive the sample within 30 hours of collection. The basic safety test is $42, bacteria alone $27, first-draw lead $32, and the fuller well tests $127 to $147.
