Fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from May 8, 2013 to Aug. 21, 2019. Newer results are in the utility’s annual water quality report.

What this report can’t tell you
Everything else. Total trihalomethanes (TTHM), nitrate, haloacetic acids (HAA5), arsenic 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. Glassbury Court at Cold Spring’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.
