The short answer

1 result is above the limit’s level with no violation recorded, and 3 more are above the health goal. The worst: Total trihalomethanes (TTHM), 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 2024.

Total trihalomethanes (TTHM), uranium, 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.

Arsenic, chromium (total) and fluoride: EPA’s compliance monitoring file, samples taken from Aug. 15, 2013 to Sept. 27, 2019. Newer results are in the utility’s annual water quality report.

Above the limit’s level, no violation recorded1

Total trihalomethanes (TTHM)

Forms or is added in treatment

Above the limit’s level, no violation

210ppb

Highest yearly average, 2020 to 2023

2023 average: 44 ppb

Averaged by year, the highest was 210 ppb, in 2022, about 2.6 times EPA’s legal limit of 80 ppb. In 2023, the latest year on file, it averaged 44 ppb. EPA judges this limit on running averages at each sampling point, and recorded no violation for total trihalomethanes (TTHM) 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 54 ppb, in 2015.

Above the health goal3

Lead

Comes from pipes, often your own

Above the health goal

5.7ppb

90th percentile, 2022 to 2024

In the latest period, 9 in 10 homes sampled were at or below 5.7 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.

Uranium

Comes from the source

Above the health goal

7.4ppb

Highest yearly average, 2020 to 2023

2023 average: 6.9 ppb

Averaged by year, the highest was 7.4 ppb, in 2020: below EPA’s legal limit of 30 ppb, but above its health goal of zero. In 2023, the latest year on file, it averaged 6.9 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 8.0 ppb, in 2017.

What handles it

Arsenic

Comes from the source

Above the health goal

1.0ppb

Highest yearly average, 2013 to 2019

2019: not found

Averaged by year, the highest was 1.0 ppb, in 2013: 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.

23ppb

Highest yearly average, 2020 to 2023

2023 average: 12.2 ppb

Averaged by year, the highest was 23 ppb, in 2020, below EPA’s legal limit of 60 ppb. In 2023, the latest year on file, it averaged 12.2 ppb. Earlier, from 2012 to 2019, EPA’s file shows a highest yearly average of 10.6 ppb, in 2015.

The highest sample, in 2021, was 2.7 ppm, below EPA’s legal limit of 10 ppm. In 2024, the latest year on file, it averaged 2.2 ppm. Earlier, from 2012 to 2019, EPA’s file shows a highest sample of 2.3 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.”

  • NSF/ANSI 53

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

    For: Total trihalomethanes (TTHM), Lead, Arsenic

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

  • NSF/ANSI 58

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

    For: Total trihalomethanes (TTHM), Lead, Uranium, Arsenic

    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. Total trihalomethanes (TTHM), uranium, 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. Arsenic, chromium (total) and fluoride come from EPA’s file alone, which ends in 2019. Starr Ridge Manor’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 Aug. 15, 2013 to Sept. 27, 2019.

Testing your own tap

Starr Ridge Manor’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.
