Strontium measured in wells tapping U.S. principal aquifers

Map of U.S. with colored dots indicating concentrations of strontium in groundwater

Detailed Description

Concentrations of strontium in samples of groundwater from drinking-water wells and shallow monitoring wells. Concentrations in drinking-water wells that exceeded the health-based screening level of 4,000 micrograms per liter largely occurred in carbonate-rock aquifers, particularly in southern Florida and central Texas, and in areas where upwelling brines mix with potable groundwater, for example in the Texas Panhandle.
