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 2.3 ppm, for the period ending June 30, 1994. None since is on file, so it is not counted as a current finding.

Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and arsenic: 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 May 6, 2014 to June 11, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal1

Uranium

Above the health goal

27ppb

Highest yearly average, 2015 to 2019

2019, one sample: 5.3 ppb

Averaged by year, the highest was 27 ppb, in 2015: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2019, the latest year on file, its one sample was 5.3 ppb.

Below EPA’s limits

34.9ppb

Highest yearly average, 2020 to 2023

2023 average: 26 ppb

Averaged by year, the highest was 34.9 ppb, in 2021, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 26 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 31.7 ppb, in 2013.

2023 average: 4.5 ppb

Averaged by year, the highest was 7.3 ppb, in 2021, below EPA’s legal limit of 60 ppb. In 2023, the latest year on file, it averaged 4.5 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.5 ppb, in 2018.

Nitrate

Below EPA’s limits

0.57ppm

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 0.57 ppm, in 2023, below EPA’s legal limit of 10 ppm. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.52 ppm, in 2019.

Chromium (total)

Comes from the source

Below EPA’s limits

4.3ppb

Highest yearly average, 2014 to 2017

2017, one sample: 2.9 ppb

Averaged by year, the highest was 4.3 ppb, in 2014, below EPA’s legal limit of 100 ppb. In 2017, the latest year on file, its one sample was 2.9 ppb.

What handles it

2 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Arsenic
  • Lead

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. Total trihalomethanes (TTHM), haloacetic acids (HAA5), nitrate and arsenic 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. Waldoboro Water Dept’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 May 6, 2014 to June 11, 2019.

Testing your own tap

Waldoboro Water Dept’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 Waldoboro Water Dept 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.
