EPHT is a cooperative initiative between the NH Department of Health and Human Services and the NH Department of Environmental Services. NH EPHT is funded by the Centers for Disease Control and Prevention (CDC) to improve public health by providing science-based information on the trends and distributions of environmentally-related diseases.

World Water Day, March 22nd

On World Water Day, people everywhere will show that they care and that they have the power to make a difference. They will get inspired by information and use it to take action and change things. This year many will focus on the power that water and jobs have to transform peoples lives. Learn more.

In the New Hampshire, the quality of community drinking water is an important public health issue because contamination in a single system can expose many people at once. State agencies, water suppliers, and water engineers work together to help ensure that drinking water contamination levels are as low as possible. This is done by protecting water sources, treating drinking water to remove contaminants, and monitoring water quality to identify problems as quickly as possible.

At New Hampshire EPHT, we would like to remind the 46% of NH households that get their drinking water from private wells to have their well-water tested for contaminants such as arsenic, nitrate, radium and uranium. Adverse effects can include gastrointestinal illness or other long-term illnesses. Some diseases, such as reproductive disorders, cancer, or neurological disorders, can be caused by exposures to contaminants and can develop over time. Sensitive groups, such as the elderly, children, and pregnant women, are more likely to suffer ill effects than the rest of the population.

Promoting Radon Awareness

Radon is a tasteless, odorless, colorless, naturally occurring, radioactive gas. It comes from the breakdown of uranium in rocks and soil. It can seep into homes through cracks and seams in foundation floors and walls. Radon can also be found in well water and can be released into the air during showering, dishwashing, and laundry. In the U.S., the average level of indoor radon is 1.25 picocuries per liter (pCi/L), but samples collected in NH homes from 1988 to 2011 suggest that 50% of homes have a concentration of 2.3 pCi/L or higher.

NH EPHT is part of the CDC's national Environmental Public Health Tracking Network. The network was developed to integrate nationally consistent environment and public health data to support research, programs and policies that help protect the health of communities nationwide.
