What was found
Haloacetic acids (HAA5), arsenic, nitrate and total trihalomethanes (TTHM): New Hampshire’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2022 to 2023.
Chromium (total), fluoride and uranium: EPA’s compliance monitoring file, samples taken from Jan. 12, 2016 to Jan. 14, 2019. Newer results are in the utility’s annual water quality report.

What this report can’t tell you
Everything else. Haloacetic acids (HAA5), arsenic, nitrate and total trihalomethanes (TTHM) results here are New Hampshire’s yearly averages as CDC publishes them, from 2022 on, with EPA’s national file for 2012 to 2019. Chromium (total), fluoride and uranium come from EPA’s file alone, which ends in 2019. Little River 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.
