Chloride in Arkansas well water
In Arkansas, chloride was detected in 100% of 9,616 tested private well samples.
Chloride mainly comes from road salt and water softener discharge. Above 250 mg/L water tastes salty and corrodes plumbing. Rising chloride in a well usually means road salt is reaching the aquifer.
