Example of wellhead plumbing typical of public wells sampled in a USGS study of 932 public wells nationwide. About 105 million people—or more than one-third of the Nation's population—receive their drinking water from one of the 140,000 public water systems across the United States that rely on groundwater pumped from public wells.

Thermal infrared mosaic of Quartzville Creek, OR. These images were captured on the year 2000 as part of an airborne thermal infrared survey conducted in the Santiam River basin, OR. The images were orthorectified and mosaicked into a single raster in order to identify and visualize thermal heterogeneity.

Long Island

More than 40 million people in the U.S. rely on domestic wells, like the one shown here, for their drinking water. Concentrations of groundwater at the wellhead typically are low, but lead can leach into the water from corrosion of household plumbing that contains lead.
