The Wise Report
The USGS has assessed water quality from 6,600 wells in regionally extensive aquifers that supply most of the groundwater pumped for the nation’s drinking water, irrigation, and other uses. A series of new USGS reports highlight how geology, hydrology, geochemistry, and chemical use affect the concentrations of individual contaminants in groundwater. Regional summaries of where and why groundwater is vulnerable to contamination now are available. The report that includes the Texas Gulf Coast can be found at:
