Well water in Lawrence County, Alabama
No public well test results have been compiled for Lawrence County yet. The USGS national arsenic model estimates that <1% of the 5,486 people on private wells there draw water with arsenic above 10 ug/L, the EPA limit, based on geology, well depth and land use rather than local tests.
The strongest signal is coliform bacteria: Recommended for every private well, every year, too few samples to carry the headline but first on the test list below.
198 test results across 15 contaminants from at least 11 wells, 1981 to 2022; manganese has the most at 25. Data refreshed September 15, 2026.

What individual samples found
Each row summarizes every public sample for that contaminant inside Lawrence County. Above limit means above the EPA maximum contaminant level; where EPA has no enforceable limit, the row shows a health guideline or nuisance level instead.

Among contaminants with a federal limit, no tested sample in Lawrence County came back above it. That is reassuring, but sampling is uneven: wells that were never tested are not in this data.
Manganese and Chloride are widespread in local groundwater. They are mainly a staining and taste problem, but high manganese also carries a health advisory for infants.

The rock under Lawrence County
Mississippian aquifers
Sandstone and carbonate-rock. Layered sandstone and limestone means a well may draw from either. Hardness and iron are routine, and the limestone layers can carry bacteria and nitrate from the surface quickly, so test for both yearly.
Classification from the USGS Principal Aquifers of the United States (national map, 2003 edition, GIS release 2015), read at the county centroid. A single well can sit in a different unit, especially near a boundary.
