The short answer

1 result is above the health goal. The worst: Uranium, above the health goal. 1 health-based violation since 2016.

What handles it

What was found

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

Chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from Feb. 1, 2012 to May 8, 2018. Newer results are in the utility’s annual water quality report.

3.0ppb

Highest yearly average, 2020 to 2024

2024 average: 2.1 ppb

Averaged by year, the highest was 3.0 ppb, in 2022: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 3.6 ppb. In 2024, the latest year on file, it averaged 2.1 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 6.0 ppb, in 2014.

2024 average: 0.33 ppm

The highest sample, in 2023, was 0.46 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it averaged 0.33 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.34 ppm, in 2018.

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. Uranium, nitrate, arsenic, haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are New York’s own yearly summaries from 2020 on, with EPA’s national file for 2012 to 2019. Chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Dover Ridge Estates’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 Feb. 1, 2012 to May 8, 2018.

Testing your own tap

Dover Ridge Estates’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.
