Iron, manganese, and arsenic are present in Twiggs County groundwater. Iron and manganese exceed EPA health standards and warrant attention.
The sandy and clay layers of the Southeastern Coastal Plain aquifer naturally contain iron and manganese minerals. As water moves slowly through these layers, it dissolves these metals from the rock and soil. Arsenic also occurs naturally in these sediments and can leach into groundwater over time.
Groundwater in this county is soft, characterized by high iron that comes from the mineral-rich sandy layers below. The acidic water moving through the Coastal Plain aquifer dissolves iron from these sediments more readily than harder rock would. High iron levels show up in wells across this county.
Wells in Twiggs County contain iron and manganese at levels above EPA health standards. Iron at high levels can cause damage to your nervous system and organs over time. Manganese also affects your nervous system and can harm your brain, especially in children and pregnant women. Arsenic is another concern in county groundwater and poses serious health risks with long-term exposure.
The high iron in county wells creates noticeable problems around your home. You will see orange or brown staining on fixtures, laundry, and anything the water touches. Iron also leaves a metallic taste and can make water smell bad. These stains are stubborn to clean and buildup happens quickly on pipes and in appliances.
We recommend testing your well water right away since every well is different and yours could have higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive metals panel typically costs two hundred to four hundred dollars and will show you exactly what you are dealing with. Iron removal systems like filters and water softeners can help address these concerns once you know your 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.
