Groundwater in Comanche County contains nitrate, iron, and manganese. These contaminants exceed EPA health standards and warrant attention from well owners.
Nitrate typically enters groundwater from fertilizers and septic systems in areas where farming and rural development are common. Iron and manganese occur naturally when water moves through the rocks beneath the county, dissolving these minerals as it flows underground.
Groundwater in this county is characterized by elevated iron and manganese from the local rock. As water seeps down through the subsurface, it picks up these metals, which are naturally present in the stone. Wells across the county commonly show these characteristics.
Comanche County wells commonly have three contaminants that exceed EPA health standards: iron, manganese, and nitrate. Manganese can affect the nervous system, especially in children and infants. Nitrate is particularly concerning for babies under six months old and can cause serious illness. Iron itself is not a direct health threat, but the other two contaminants present real risks that deserve attention.
County well water with elevated iron and manganese causes staining and discoloration. You may see rust-colored or dark brown stains on sinks, toilets, and laundry. These minerals can create buildup inside pipes and reduce water flow over time. The water may have a metallic taste or unpleasant odor that affects drinking and cooking.
We recommend testing your well to find out what is actually in your water, since every well is different and yours may have higher or lower levels than what is common here. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars and will tell you exactly what you are dealing with. Testing is the only way to know if treatment is needed and what kind would work best for your situation. Iron filters or water softeners can address some of 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.
