Groundwater in Wilkinson County contains manganese, iron, nitrite, chloride, and sulfate. Several of these contaminants exceed EPA health standards, which means well owners should have their water tested and take action if their results show high levels.
These contaminants come from the sandy and clay layers that make up the local aquifer system. Iron and manganese naturally dissolve from the rocks when groundwater sits underground for a long time. Nitrite, chloride, and sulfate can seep in from septic systems, fertilizers, road salt, and other land activities on the surface. The sandy soils here let water move down quickly, so contaminants from above reach the groundwater.
Groundwater in this county is notably high in iron, which is the dominant mineral affecting water character. The iron comes from minerals in the sandy and clay rocks that release iron as water flows through them. Iron is present at very high levels in wells across this county, making it the main water quality feature well owners will notice.
Wells in Wilkinson County show high levels of chloride, iron, manganese, nitrite, and sulfate above EPA health standards. Chloride and nitrite can damage your kidneys and interfere with how your body uses oxygen. Manganese exposure harms your nervous system and can affect learning and movement, especially in children. Iron and sulfate at elevated levels also pose health concerns for your family.
The high iron in county wells causes orange or brown staining on sinks, toilets, and laundry that is very hard to remove. You may notice a metallic taste in your water and rust-colored buildup in pipes. These stains and buildup are annoying to clean and can happen quickly.
We recommend getting your well tested right away with a comprehensive panel that checks for all metals and minerals. Testing is the only way to know exactly what is in your well, since every well is different and yours could have higher or lower levels than the county average. A comprehensive panel typically costs two hundred to four hundred dollars. Treatment options like iron filters and water softeners can help reduce these contaminants.

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.
