The short answer
1 result is above the limit’s level with no violation recorded. The worst: Arsenic, above the limit’s level, no violation. 10 health-based violations since 2016.
What handles itWhat 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 July 10, 2012 to May 16, 2018. Newer results are in the utility’s annual water quality report.
Above the limit’s level, no violation recorded1
Arsenic
Comes from the source
11.3ppb
Highest yearly average, 2021 to 2023
2023 average: 5.3 ppb
Averaged by year, the highest was 11.3 ppb, in 2021, above EPA’s legal limit of 10 ppb. In 2023, the latest year on file, it averaged 5.3 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for arsenic at this utility since 2020. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 15.7 ppb, in 2013, and EPA recorded violations in 2012, 2013, 2014, 2015, 2016, 2017 and 2018.

2024 average: 8.8 ppb
Averaged by year, the highest was 17.1 ppb, in 2023, below EPA’s legal limit of 80 ppb. Its highest single sample was 24.6 ppb. In 2024, the latest year on file, it averaged 8.8 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 12.8 ppb, in 2015.

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. Dryden Village’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 July 10, 2012 to May 16, 2018.
