Groundwater in Jasper County contains manganese, iron, chloride, and nitrate at levels that exceed EPA health standards. These are contaminants that well owners need to address in their water.
These metals and salts come from the rocks beneath the county. Iron and manganese occur naturally in the local geology and leach into groundwater as water moves through the rock layers. Chloride and nitrate can come from both natural sources in the soil and rock, and from human activities like agriculture and septic systems on the land above.
Groundwater in Jasper County is soft and characterized by moderate levels of iron and moderate sodium. The local rocks release these minerals as groundwater slowly dissolves them over time. These characteristics are common across many wells in the county.
Wells in Jasper County commonly have four contaminants above EPA health standards: chloride, iron, manganese, and nitrate. Chloride at high levels can harm people with heart disease or high blood pressure. Iron and manganese can cause nervous system problems in infants and children if consumed over time. Nitrate poses a serious risk to babies under six months old and can interfere with oxygen in the blood.
The mineral content in county wells creates staining on fixtures and laundry. Iron leaves rust-colored marks on sinks and toilets. You may notice a metallic taste in your water or see brown discoloration in your ice maker or dishwasher. These minerals do not make water hard, but they do create cleaning headaches and affect how your water looks and tastes.
We recommend testing your well right away with a comprehensive panel since multiple contaminants exceed health standards in this county. Every well is different, and your water could have much higher or lower levels than what is common here. Testing is the only way to know what is actually in your well so you can get the right treatment. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars, and treatments like chloride reduction systems or iron filters can address these concerns.

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.
