The short answer
Nothing in EPA’s and New York’s records for this utility is above a health goal. That covers nitrate, arsenic and other regulated chemicals, plus lead and copper, not everything. 2 health-based violations since 2016.

Arsenic, haloacetic acids (HAA5), nitrate, total trihalomethanes (TTHM) and uranium: New York’s yearly summaries per water system, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.
Fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from Feb. 4, 2013 to Nov. 12, 2019. Newer results are in the utility’s annual water quality report.

What this report can’t tell you
Everything else. Arsenic, haloacetic acids (HAA5), nitrate, total trihalomethanes (TTHM) and uranium 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. Mirror Lake Trailer Park’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.
