Groundwater in Terrell County contains manganese, arsenic, and chloride. Manganese is present at levels that exceed the EPA health standard, which is a concern that well owners should address.
Manganese enters groundwater naturally from the rocks and soil in this region. The Southeastern Coastal Plain aquifer system contains sediments rich in manganese-bearing minerals that dissolve slowly into water as it moves underground. Arsenic and chloride also come from natural rock sources in this area, though their levels are lower than manganese.
Groundwater in Terrell County is moderately hard, driven by calcium and magnesium dissolved from the surrounding rock layers. These minerals accumulate in water as it sits underground and passes through sediment. Most wells in this county show this moderate hardness, making it a common feature of local water.
Wells in Terrell County commonly have manganese at levels above EPA health standards. Manganese is a metal that can affect your brain and nervous system, especially in children. Exposure over time can cause problems with learning, movement, and behavior. Testing your well is the first step to understanding this risk for your family.
The moderately hard water in county wells can leave spots on dishes and shower doors. You might notice staining on bathroom fixtures or a buildup of scale inside pipes and appliances. Hard water can shorten the lifespan of water heaters and dishwashers because of mineral deposits. The water itself should taste normal, but mineral buildup in your system is still a concern.
We recommend testing your well water, since every well in this county is different and yours could have higher or lower levels than the county average. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive metals and minerals panel usually costs between two hundred and four hundred dollars. Treatments like filtration systems or water softeners can help address both manganese and hardness problems.

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.
