The New Hampshire (NH) Tracking Program will help policymakers, health professionals, scientists, researchers and others to:

  • Advance research on possible linkages between environmental hazards and disease;
  • Monitor information about environmental hazards and disease trends;
  • Track advances in health status and environmental improvements; and
  • Use data to develop, implement, and evaluate regulatory and public health actions to prevent or control environment-related diseases.

Quick Stats:

  • New Hampshire has one of the highest rates of Lyme disease in the country.
  • New Hampshire has the highest rate of bladder cancer cases in the nation—37% higher than the national rate, according to data from the Centers for Disease Control and Prevention. One of the leading causes of bladder cancer in the state is exposure to arsenic in private drinking water wells.
  • 44% of NH households have a private well for their main source of water. Unhealthy levels of contaminants are common in many private wells.

Unique Data:

In addition to the set of standard data collected and displayed by all state and local tracking programs, individual programs may host data that are important to their populations.


Assessing Exposure to Contaminated Drinking Water: Working with other state agencies, the NH Tracking Program responded to communities affected by contaminated private drinking water wells and public drinking water systems. The Tracking Program interpreted perfluorochemical (PFC) blood tests for individuals who lived on, worked at, or attended childcare at the Pease Tradeport industrial community. They also provided blood tests for residents in Southern NH communities where PFCs contaminated private drinking water wells, as well as in the Merrimack Village District (MVD) public water system. Tracking staff analyzed results to determine the extent of exposure, including evaluating the relationship between water consumption, residential history, and the PFC levels found in individuals’ blood. NH Tracking displays aggregate (not individual) blood test resultsExternal from each testing location.
