Well Water Nerd

Well water in Brooks County, Georgia

In Brooks County, none of 38 tested well samples exceeded the EPA limit for fluoride, based on public data from USGS Water Quality Portal.

The strongest signal is arsenic: 7% of 29 local samples were above the limit, too few samples to carry the headline but first on the test list below.

281 test results across 12 contaminants from at least 23 wells, 1938 to 2024; fluoride has the most at 38. Data refreshed September 15, 2026.

Compiled by Nick at Well Water Nerd from public records. How these pages are built

An estimated 7,962 people in Brooks County get their drinking water from a private well, per USGS 2015 county water use. That is about 51% of residents.

Separately, the USGS national arsenic model estimates that 5% of the 7,962 people on private wells in Brooks County draw water above 10 ug/L (the model's range is 3% to 8%), from geology and well depth rather than local tests.

What individual samples found

Each row summarizes every public sample for that contaminant inside Brooks 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.

What this means

The contaminants most often above their limit here are arsenic (7% of 29 samples). A well next door can differ sharply from yours because bedrock fractures, well depth and plumbing all matter, so these rates describe the area, not your tap.

Manganese is widespread in local groundwater. It is mainly a staining and taste problem, but high manganese also carries a health advisory for infants.

The rock under Brooks 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.
