Groundwater in Throckmorton County contains iron, nitrate, and fluoride. These contaminants exceed EPA health standards in this area's wells.
Iron, nitrate, and fluoride dissolve naturally from the rock layers beneath the county as water moves slowly through the ground. The local rocks release these minerals into the water over time, and they accumulate where wells draw from deeper zones.
Groundwater in this county is high in iron. Iron dissolves from the rock as water sits underground, and fluoride does the same. These mineral characteristics show up across many wells in the county.
Fluoride, iron, and nitrate show up at high levels in wells across this county. Fluoride at these concentrations can damage children's developing teeth and affect bone health over time. Nitrate is especially harmful to infants and can interfere with how their blood carries oxygen. Iron itself does not cause direct health problems, but the other contaminants present alongside it do need attention.
High iron in county wells creates rust-colored stains on fixtures, laundry, and dishes that are difficult to remove. Water may have a metallic taste and smell. These stains can build up in pipes and reduce water flow over time. Soap and shampoo don't work as well, and you may notice discoloration when water sits in a toilet bowl.
Your well is unique and could have much higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. We recommend a comprehensive metals and minerals panel since multiple contaminants are a concern, which typically costs between $200 and $400. Treatment options like reverse osmosis systems or specialized filters can address these issues once you know your specific results.

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.
