Lead in the water: A corrosive danger lurks in U.S. water wells

Researchers from Penn State Extension and Virginia Polytechnic Institute and State University, or Virginia Tech, tested private well systems in their states and found that 12 percent of wells in Pennsylvania and 19 percent in Virginia had lead levels exceeding the maximum EPA threshold for public water systems. Lead poisoning can lead to heart disease, kidney disease and brain damage. It is especially dangerous to children, as small amounts of exposure can cause irreversible developmental delays.

Though most Americans are served by public water utilities, private wells are the main source of drinking water for 15 percent of U.S. households, or 47.8 million people. Typically located in rural areas, private wells serve residents not connected to municipal water lines. Though many wells are found in impoverished communities, some serve wealthy homeowners and those living in urban environments.
