Well water in Jeff Davis County, Georgia
No public well test results have been compiled for Jeff Davis County yet. The USGS national arsenic model estimates that 5% of the 8,589 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.
23 test results across 6 contaminants from at least 6 wells, 1960 to 1990; chloride has the most at 7. Data refreshed September 15, 2026.

Among contaminants with a federal limit, no tested sample in Jeff Davis County came back above it. That is reassuring, but sampling is uneven: wells that were never tested are not in this data.
Chloride and Iron 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 Jeff Davis County
Surficial aquifer system
Unconsolidated sand and gravel. Wells in sand and gravel are usually shallow and productive, and they recharge quickly from the surface. That makes them the most exposed to nitrate, bacteria and anything spilled nearby, and the least likely to carry arsenic or radon from the rock.
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.

Non-detects count as samples and are treated as zero when computing medians. Exactly at the limit counts as not above it. A sample belongs to the town containing the well's reported coordinates.
