The Biomonitoring New Hampshire Program evaluates exposure to environmental chemicals by testing human specimens such as blood, serum, and urine for those chemicals or their metabolites. These chemicals may be natural, such as arsenic and uranium from groundwater, or they may be man-made, such as pesticides from agriculture.

New Hampshire was one of six awardees to receive a Centers for Disease Control and Prevention (CDC) grant for Biomonitoring in 2019 and one of only two states to be refunded after the 2014-2019 Cooperative Agreement. The program is also part of the National Biomonitoring Network. This is a collaboration of federal, regional, state and local laboratories working to advance biomonitoring using high quality practices to answer environmental health questions.
