Groundwater in Twiggs County contains iron, manganese, and arsenic. Iron and manganese are present at levels that exceed EPA health standards, which means well owners should test their water and consider treatment.
These metals come from the sandy and clay layers beneath the county. As water moves slowly through these sediments, it dissolves iron and manganese naturally present in the rock. The low-oxygen environment underground makes these metals more likely to stay dissolved in water rather than settle out.
Groundwater in this county is notably high in iron, which is the main mineral character of the water. Iron concentrates here because the Coastal Plain sediments contain iron-bearing minerals that release iron as groundwater passes through them. Wells across Twiggs County commonly show elevated iron levels.
Wells in Twiggs County show elevated iron and manganese at levels that exceed EPA health standards. Iron can cause problems with your blood and organs over time. Manganese can affect your brain and nervous system, especially in children and babies. Both metals need attention if they are present in your well.
County wells with high iron cause orange or brown staining on sinks, toilets, and laundry. The water may taste metallic or look discolored. Iron can clog pipes and fixtures. The good news is that Twiggs County water is soft, so you will not see scale buildup or need to worry about appliance damage from hardness.
We recommend testing your well to find out what metals are actually in your water. Every well is different, and your water could have higher or lower levels than the county average. A comprehensive metals panel costs between two hundred and four hundred dollars and is the only way to know what needs treatment. Iron and manganese can be removed with filtration systems or other treatment methods designed for your specific levels.

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.
