Everything else. Arsenic, nitrate, total trihalomethanes (TTHM) and uranium results here are New Hampshire’s yearly averages as CDC publishes them, from 2023 on, with EPA’s national file for 2012 to 2019. Residential Camp Monadnock’s own annual report, which it must send you every year, has 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.
