The short answer

3 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

Lead and copper: EPA SDWIS monitoring periods ending 2021 to 2026.

Uranium, nitrate, total trihalomethanes (TTHM) and haloacetic acids (HAA5): Connecticut’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.

Arsenic, fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from May 16, 2012 to Dec. 6, 2019. Newer results are in the utility’s annual water quality report.

Above the health goal3

Arsenic

Comes from the source

Above the health goal

2.0ppb

Highest yearly average, 2012 to 2019

2019: not found

Averaged by year, the highest was 2.0 ppb, in 2018: below EPA’s legal limit of 10 ppb, but above its health goal of zero. In 2019, the latest year on file, it wasn’t found in its one sample.

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

5.2ppb

Highest yearly average, 2022

Averaged by year, the highest was 5.2 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 2.3 ppb, in 2019.

What handles it

Lead

Comes from pipes, often your own

Above the health goal

0.3ppb

90th percentile, 2026

In the latest period, 9 in 10 homes sampled were at or below 0.3 ppb, below EPA’s action level of 15 ppb. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

What handles it

Fluoride

Forms or is added in treatment

Below EPA’s limits

0.82ppm

Highest yearly average, 2012 to 2019

2019 average: 0.72 ppm

Averaged by year, the highest was 0.82 ppm, in 2018, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 1.6 ppm. In 2019, the latest year on file, its 13 samples averaged 0.72 ppm.

What handles it

Nitrate

Comes from the source

Below EPA’s limits

0.38ppm

Highest yearly average, 2020 to 2023

2023 average: 0.33 ppm

Averaged by year, the highest was 0.38 ppm, in 2020, below EPA’s legal limit of 10 ppm. In 2023, the latest year on file, it averaged 0.33 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 5.8 ppm, in 2013.

What handles it

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

Total trihalomethanes (TTHM)

Forms or is added in treatment

Below EPA’s limits

3.0ppb

Highest yearly average, 2020 to 2023

2023 average: 2.3 ppb

Averaged by year, the highest was 3.0 ppb, in 2022, below EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 2.3 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 5.6 ppb, in 2017.

Haloacetic acids (HAA5)

Forms or is added in treatment

Below EPA’s limits

1.4ppb

Highest yearly average, 2020 to 2023

2023: not found

Averaged by year, the highest was 1.4 ppb, in 2022, below EPA’s legal limit of 60 ppb. In 2023, the latest year on file, it wasn’t found. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 3.0 ppb, in 2018.

  • Chromium (total)

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, Lead Reduction

    For: Arsenic, Lead

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

  • NSF/ANSI 58

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

    For: Arsenic, Uranium, Lead

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

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 can’t tell you

  • Everything else. Uranium, nitrate, total trihalomethanes (TTHM) and haloacetic acids (HAA5) results here are Connecticut’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Arsenic, fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Bethany Mobile Home Park’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 Connecticut cover 2020 to 2023; EPA’s compliance samples are from May 16, 2012 to Dec. 6, 2019.

Testing your own tap

Bethany Mobile Home Park’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 Connecticut certifies.
