The quality and safety of some private drinking water wells across the country is an issue of concern, according to a U.S. Geological Survey study.
About 43 million people-or 15 percent of the Nation`s population-rely on private wells for drinking water.
USGS scientists sampled 2,100 wells in 48 states from 30 of the Nation`s 62 major aquifers. As many as 219 properties and contaminants, such as pH, major ions, nutrients, radionuclides, trace elements, pesticides, volatile organic compounds, and microbial contaminants were measured.
The media is invited to attend a congressional briefing where the overall quality and safety of private well water will be announced. Experts will describe how cooperating federal agencies are using the information to answer important questions to address public health issues, including research by the National Cancer Institute on arsenic in drinking water and relations to bladder cancer.
