The short answer

1 result is above the limit’s level with no violation recorded, and 2 more are above the health goal. The worst: Fluoride, above the limit’s level, no violation. No health-based violations on file since 2016.

What handles it

What was found

Lead and copper: EPA SDWIS monitoring periods ending 1993 to 2026.

Uranium, nitrate, haloacetic acids (HAA5) and total trihalomethanes (TTHM): New York’s yearly summaries per water system, 2023 to 2024, with EPA’s 2012 to 2019 file for earlier years.

Fluoride, arsenic and chromium (total): EPA’s compliance monitoring file, samples taken from May 22, 2013 to May 22, 2013. Newer results are in the utility’s annual water quality report.

Above the limit’s level, no violation recorded1

Fluoride

Forms or is added in treatment

Above the limit’s level, no violation

12ppm

Highest yearly average, 2013

Averaged by year, the highest was 12 ppm, in 2013, about 3 times EPA’s legal limit of 4.0 ppm. That is the only year on file. EPA judges this limit on running averages at each sampling point, and recorded no violation for fluoride at this utility from 2012 to 2019. Results like these with no violation often include water sampled before treatment or blending; the utility’s annual report says what reaches the tap.

What handles it

Above the health goal2

Lead

Comes from pipes, often your own

Above the health goal

6.0ppb

90th percentile, 2024 to 2026

In the latest period, 9 in 10 homes sampled were at or below 6.0 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

Uranium

Comes from the source

Above the health goal

1.8ppb

Highest yearly average, 2023

Averaged by year, the highest was 1.8 ppb, in 2023: below EPA’s legal limit of 30 ppb, but above its health goal of zero. Its highest single sample was 2.5 ppb. That is the only year on file. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 1.6 ppb, in 2017.

What handles it

Below EPA’s limits1

Nitrate

Comes from the source

Below EPA’s limits

1.1ppm

Highest sample; found in 4 of 4

2024 average: 0.78 ppm

The highest sample, in 2024, was 1.1 ppm, below EPA’s legal limit of 10 ppm. That was also the latest year on file, and it averaged 0.78 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 0.5 ppm, 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

    Claims: Fluoride, Lead Reduction

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, haloacetic acids (HAA5) and total trihalomethanes (TTHM) results here are New York’s own yearly summaries from 2023 on, with EPA’s national file for 2012 to 2019. Fluoride, arsenic and chromium (total) come from EPA’s file alone, which ends in 2019. Alpine Acres Water District’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 2023 to 2024; EPA’s compliance samples are from May 22, 2013 to May 22, 2013.

Testing your own tap

Alpine Acres Water District’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.
