High or very high prevalence of corrosive groundwater was discovered in 25 states in a 2016 U.S. Geological Survey (USGS) assessment of 20,000 wells across the U.S. USGS looked for two indicators of potential corrosivity and found corrosive groundwater in all 50 states and Washington DC.
Alabama, Delaware, Connecticut, Georgia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, Rhode Island, South Carolina and the District of Columbia all had a very high prevalence of potentially corrosive groundwater.
Arkansas, Florida, Louisiana, Mississippi, North Carolina, New York, Oregon, Pennsylvania, Tennessee, Vermont, Virginia, West Virginia and Washington each had a high prevalence of potentially corrosive groundwater.
"The corrosivity of untreated groundwater is only one of several factors that may affect the quality of household drinking water at the tap," USGS Associate Director for Water Don Cline said. "Nevertheless, it is an essential factor that should be carefully considered in testing for water quality in both public and private supplies nationwide."
The survey, titled Assessing the Potential Corrosivity of U.S. Groundwater," also found that, while approximately 15 percent of the population depends on private wells for drinking water, many do not perform the basic testing necessary to ensure safe water.

Water supplies affected in two Canadian cities after Husky oil spill
Two cities in Canada’s Saskatchewan province have stopped drawing drinking water from the North Saskatchewan River after a Husky Energy Inc. pipeline leaked oil and diluent into the river on July 21. Efforts to contain the spill the following day were unsuccessful.
The city of North Battleford stopped drawing drinking water quickly after the spill, and the city of Prince Albert was forced to do the same on July 25. Prince Albert officials met the same day to explore plans for dealing with the issue including restricting water use for residents and using rainwater after reserves were exhausted.
The oil spill is expected to cost the cities millions of dollars and hit nearby farmers, who depend on Prince Albert’s water supply, most severely, according to reuters.com.
