Iron, manganese, and nitrate are present in groundwater across Eastland County and exceed EPA health standards. These levels are concerning enough to warrant attention from well owners.
Iron and manganese dissolve into water naturally as it moves through the rock layers beneath the county. Nitrate enters groundwater from agricultural sources like fertilizers and animal waste that seep down from the surface.
Groundwater in this county contains elevated iron and manganese from the local rocks. Water passing through these formations picks up these metals as it travels underground. Both contaminants show up in a significant portion of wells tested in the area.
Wells in Eastland County commonly show iron, manganese, and nitrate at levels above EPA health standards. Iron and manganese can damage your nervous system with long-term exposure. Nitrate is especially dangerous for babies and young children, as it can interfere with how their blood carries oxygen.
Iron in county well water leaves rusty stains on sinks, toilets, and laundry. Manganese creates brown or black stains that are hard to remove. Both minerals can build up scale inside pipes and reduce water flow over time. You might notice a metallic or bitter taste in the water.
We recommend testing your well water, since every well is different and yours could have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your water so it can be properly treated. A comprehensive metals and minerals panel typically costs between $200 and $400. Treatment options like iron removal filters or nitrate reduction systems can address these concerns once you know your specific 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.
