The short answer

2 results are above the health goal. The worst: Arsenic, above the health goal. No health-based violations on file since 2016.

What handles it

What was found

Arsenic, haloacetic acids (HAA5), nitrate 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 June 11, 2014 to April 1, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal2

Arsenic

Comes from the source

Above the health goal

4.4ppb

Highest yearly average, 2020 to 2023

Averaged by year, the highest was 4.4 ppb, in 2023: below EPA’s legal limit of 10 ppb, but above its health goal of zero. That was also the latest year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 4.9 ppb, in 2017.

What handles it

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

Uranium

Comes from the source

Above the health goal

2.2ppb

Highest yearly average, 2017 to 2019

2019, one sample: 2.1 ppb

Averaged by year, the highest was 2.2 ppb, in 2017: 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 2.1 ppb.

What handles it

Below EPA’s limits2

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.1ppm

Highest yearly average, 2014 to 2017

2017, one sample: 0.1 ppm

Averaged by year, the highest was 0.1 ppm, in 2014, below EPA’s legal limit of 4.0 ppm. In 2017, the latest year on file, its one sample was 0.1 ppm.

What handles it

Chromium (total)

Comes from the source

Below EPA’s limits

2.4ppb

Highest yearly average, 2014 to 2017

2017, one sample: 2.2 ppb

Averaged by year, the highest was 2.4 ppb, in 2014, below EPA’s legal limit of 100 ppb. In 2017, the latest year on file, its one sample was 2.2 ppb.

What handles it

4 compounds tested and not foundBelow the reporting level in every sample. Not found is not the same as zero.
  • Haloacetic acids (HAA5)
  • Lead
  • Nitrate
  • 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.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    Other certifiers’ wording: Arsenic (III) (50 ppb influent level)

  • NSF/ANSI 58

    Claims: Arsenic (Pentavalent)<=50 ppb Reduction, Uranium

    For: Arsenic, Uranium

    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, haloacetic acids (HAA5), nitrate 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. Dover Realty Ventures MHP LLC’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 June 11, 2014 to April 1, 2019.

Testing your own tap

Dover Realty Ventures MHP LLC’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.

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.
