Groundwater in Colquitt County contains sulfate, arsenic, and chloride. Sulfate levels exceed the EPA health standard, while arsenic and chloride are present at levels that warrant awareness.
These contaminants come from the rock layers underneath the county. Sulfate can dissolve from minerals in the subsurface rock, and both arsenic and chloride occur naturally in certain rock types. The particular rocks beneath Colquitt County release these substances into the water as it filters through.
Groundwater in this county is moderately hard, driven by moderate iron and moderately hard calcium and magnesium content. These minerals dissolve as water moves through the rock beneath the surface, and the moderately hard character is common across wells in the county.
Wells in Colquitt County commonly show sulfate at levels that exceed EPA health standards. Drinking water with elevated sulfate can cause digestive problems, especially in infants and people with certain health conditions. Sulfate can also interact with other minerals in your water in ways that affect your stomach and intestines. This is a concern worth understanding for your family's health.
The moderate hardness in county wells can leave white scale buildup on faucets and fixtures and make it harder for soap to lather. You might notice spots on dishes after washing or feel a filmy residue on your skin after showering. Hard water can also shorten the lifespan of water heaters and dishwashers over time because of mineral deposits inside them.
We recommend testing your well water to find out what is actually in it, since every well is different and yours could have higher or lower levels than what is common in the county. A comprehensive panel that checks for metals and minerals runs between $200 and $400 and will give you a complete picture. Testing is the only way to know if treatment is needed, and options like sulfate filters or water softeners can address specific problems once you know what you are dealing with.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
