Well water testing is commonly conducted as part of a home sale agreement or inspection. However, water should also be monitored on an ongoing basis and should be re-tested every few years to ensure no new sources of contamination have been introduced. If you are unsure, please contact ChemServe for advice regarding the type of water testing needed for your particular situation.
New limits for arsenic in drinking water
Arsenic occurs naturally in the bedrock of many parts of New Hampshire increasing exposure levels for residents through drinking water. From July 2021 the maximum contaminant level of arsenic in drinking water in NH will be halved from 10 parts-per-billion to 5 parts-per-billion. 46% of all NH residents drink from private wells. According to a report from the Dartmouth Superfund Research program two-thirds of all private wells in NH have over 1 ppb of arsenic, and about 30% have arsenic above the new NHDES limit of 5 ppb. The new limits are not mandatory for homeowners but are recommended based on epidemiological studies on the role of arsenic in human health.
ChemServe offers Arsenic testing in drinking water as part of a package or a stand-alone test. Our sensitive equipment can detect arsenic to 1 ppb.
