|Study Shows High Potential for Corrosive Groundwater in Maryland, Delaware, the District of Columbia, and Many Other States
A new U.S. Geological Survey assessment of more than 20,000 wells nationwide shows that untreated groundwater in 25 states has a high prevalence of being potentially corrosive. The states with the largest percentage of wells with potentially corrosive groundwater are located primarily in the Northeast, the Southeast, and the Northwest United States.
