Wilkinson County groundwater contains manganese, iron, nitrite, chloride, and sulfate at levels that exceed EPA health standards. These contamination levels are serious and require attention from well owners.
These metals come from the sandy and clay layers that make up the Southeastern Coastal Plain aquifer beneath the county. As groundwater moves slowly through these rocks over time, iron and manganese dissolve into the water. Nitrite and chloride can enter groundwater from septic systems, agricultural runoff, and natural mineral deposits in the soil and rock layers.
Groundwater in this county is notably high in iron, which is the dominant mineral driving water character. Iron concentrates here because the coastal plain rocks naturally release this metal as water moves through them in a low-oxygen environment underground. Most wells in Wilkinson County show elevated iron, making this a widespread condition across the area.
Wells in Wilkinson County commonly exceed EPA health standards for chloride, iron, manganese, nitrite, and sulfate. Iron and manganese are metals that build up in your body over time and can harm your brain, nervous system, and organs. Nitrite is especially dangerous for babies and can prevent their blood from carrying oxygen properly. Chloride at high levels can raise blood pressure in some people.
County wells show very high iron, which causes orange or brown staining on toilets, sinks, bathtubs, and laundry that is hard to remove. The water may taste metallic or unpleasant. Iron can clog your pipes and fixtures over time and damage appliances. Even though the water is soft, the iron creates real problems in your home.
We recommend testing your well water with a comprehensive metals panel to find out exactly what is in your water, since every well is different and yours could have higher or lower levels than the county average. Testing is the only way to know what needs treatment in your specific well. A comprehensive panel usually costs between two hundred and four hundred dollars. Iron removal filters and water softeners can help address these 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.
