Source: Alabama Department of Environmental Management, Drinking Water Branch, 238 utilities, results from Jan. 12, 2015 to Sept. 21, 2026, read Oct. 17, 2026. Each sampling point is taken at its median; a figure is typical where every point falls in one band.

Bands are the U.S. Geological Survey’s, at 17.1 mg/L to the grain. People served is what each utility reports; where one sells water to another, the same people can be counted twice. How hardness is measured here.
