Map: Probability of elevated radon in New Hampshire groundwater.
This is the most comprehensive study to date and the first to create detailed statewide maps on the probability for any location in New Hampshire to have groundwater with either of those two radioactive elements.
Both radon and uranium can be a concern to human health in communities that have private wells. Approximately 40% of New Hampshire residents rely on private wells for uses such as drinking water, and those wells are supplied by groundwater.
The recent study represents groundwater and not necessarily drinking water, as groundwater can be filtered or treated prior to becoming drinking water. USGS scientists investigated where the substances, which are naturally occurring, may exist and in some cases be elevated above safe drinking water levels in accordance with standards identified by the state or the U.S. Environmental Protection Agency.
The EPA regulates public water supplies, but maintenance, testing and treatment of private water supplies are the responsibility of the homeowner. These findings highlight the importance of private well owners working with their local and state officials to determine the best way to test and, if necessary, treat their water supplies. Unless wells are tested, there’s no way to confirm the presence or absence of […]
