Many U.S. Drinking Water Wells Contaminated
Private drinking water wells are unmonitored and unregulated, but often contaminated with potentially dangerous elements

In Nebraska, along the Platte River, it’s uranium. In Maine, New Hampshire and Massachusetts, it’s arsenic. In California, boron. And in the Texas Panhandle, lithium.
Throughout the nation, metals and other elements are tainting private drinking water wells at concentrations that pose a health concern.
For one element – manganese – contamination is so widespread that water wells with excessive levels are found in all but just a few states. Arsenic, too, is a national problem, scattered in every region.
