Groundwater in Dougherty County contains nitrate, arsenic, and manganese at levels that exceed EPA health standards. Chloride and iron are also present above safe drinking water limits, making testing and treatment necessary for well owners in this area.
These contaminants come from both natural and human sources. Arsenic, manganese, and iron are released from the rock and soil as groundwater moves slowly underground. Nitrate enters from fertilizer use on farms and from septic systems, seeping down into the water supply.
Groundwater in Dougherty County is hard, driven by calcium and magnesium that dissolve from the local rock as water passes through. The underlying geology here releases these minerals into the water over time. Hard water is widespread across wells throughout the county.
Dougherty County wells commonly contain arsenic, chloride, iron, manganese, and nitrate at levels above EPA health standards. Arsenic builds up in your body over time and can damage your kidneys, heart, and nervous system. Nitrate is especially dangerous for infants and can interfere with how blood carries oxygen. Chloride, iron, and manganese also pose health risks with long-term exposure.
Hard water is common in Dougherty County wells. You will see rust-colored or brown staining on bathroom fixtures and laundry. Scale buildup inside pipes and appliances like water heaters and dishwashers can shorten their lifespan. Dishes may spot after washing, and you might notice a metallic taste or odor in the water.
We recommend testing your well because every well is different--your water may have higher or lower levels than what is typical in the county. Testing is the only way to know what is actually in your well so you can treat it properly. For this county, a comprehensive metals and minerals panel is recommended due to multiple contaminants exceeding health standards, typically running $200 to $400. Treatment options like arsenic removal systems, water softeners, or iron and manganese filters can address these concerns.

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.
