The short answer

1 result is above EPA’s legal limit. The worst: Arsenic, above the legal limit. 1 health-based violation since 2016.

What handles it

What was found

Arsenic, total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate: New York’s yearly summaries per water system, 2020 to 2024, with EPA’s 2012 to 2019 file for earlier years.

Fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from Sept. 9, 2013 to April 8, 2019. Newer results are in the utility’s annual water quality report.

Above the legal limit1

Arsenic

Comes from the source

Above the legal limit

11.9ppb

Highest yearly average, 2020 to 2024

2024 average: 0.95 ppb

Averaged by year, the highest was 11.9 ppb, in 2020, above EPA’s legal limit of 10 ppb. Its highest single sample was 16 ppb. In 2024, the latest year on file, it averaged 0.95 ppb. EPA recorded a violation for arsenic at this utility in 2020. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 10.9 ppb, in 2012, and EPA recorded a violation in 2012.

2019: not found

Averaged by year, the highest was 0.1 ppm, in 2016, below EPA’s legal limit of 4.0 ppm. Its highest single sample was 0.2 ppm. In 2019, the latest year on file, it wasn’t found in any of its two samples.

  • Chromium (total)
  • 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.”

  • NSF/ANSI 53

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

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

  • NSF/ANSI 58

    Claim: Arsenic (Pentavalent)<=50 ppb Reduction

    For: Arsenic

    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, total trihalomethanes (TTHM), haloacetic acids (HAA5) and nitrate results here are New York’s own yearly summaries from 2020 on, with EPA’s national file for 2012 to 2019. Fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. Twin Lakes Mobile Homes’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; New York’s yearly summaries cover 2020 to 2024; EPA’s compliance samples are from Sept. 9, 2013 to April 8, 2019.

Testing your own tap

Twin Lakes Mobile Homes’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 New York certifies.
