Manganese in Alabama well water, by county

Manganese is worth checking in 4 of the 5 Alabama counties with 10 or more tested wells, and rare in the rest. A county's share tells you how likely a problem is nearby. Only a test of your own well tells you what's in it.

How Alabama compares with the rest of the country

Across Alabama, about 1 in 11 tested wells had manganese over the EPA health advisory of 0.3 mg/L (18 of 205). Across all tested wells in the US it's about 1 in 7. That's less often than in the country as a whole. Counties still differ, so check yours below.

Why it matters: High levels over many years may affect the nervous system, and babies are more sensitive to it. It also leaves black stains.

Manganese dissolves out of rock and soil, especially in water with little oxygen.

* Likely overstated. These shares come from a narrow set of wells, so they probably run high for the county as a whole:

  • Montgomery County: All of these tests come from the US Geological Survey, mostly before 2013 in one small part of the county, so this likely overstates it.

36 more Alabama counties have 1 to 9 tested wells for manganese, too few to rate.

Where these numbers come from

  • Lab tests: Water Quality Portal (USGS and EPA), well samples since 2000. A well counts as over if any of its tests was over the EPA health advisory of 0.3 mg/L. Wells tested for studies and monitoring, not a random sample of homes.
  • Likely overstated: our own check of who tested the wells, when and where. How we check.
  • State programs and links: Department of Public Health (county health departments); labs certified by Department of Environmental Management.
