Sulfate, chloride, iron, manganese, fluoride, and nitrate are present in Mitchell County groundwater. Multiple contaminants exceed EPA health standards at concerning levels.
The rock layers beneath this county naturally contain salt, sulfate, and iron minerals that dissolve into groundwater as water moves through them. The dry climate means less rain to dilute these minerals. Past oil and gas activity in the area may also contribute to elevated chloride and sulfate concentrations.
Mitchell County groundwater is very hard and carries extremely high sodium and sulfate alongside elevated iron. These minerals come from the deep rock formations below, where salty and mineral-rich layers are common in West Texas geology. Most wells in the county show these same strong mineral characteristics.
Wells in Mitchell County commonly exceed EPA health standards for chloride, fluoride, iron, manganese, nitrate, and sulfate. Chloride and fluoride at elevated levels can affect kidney function and bone health over time. Iron and manganese can harm the nervous system and organs with long-term exposure. Nitrate is particularly dangerous for infants and pregnant women, causing serious blood oxygen problems.
The extremely hard water in this county creates stubborn staining on fixtures and clothing. Iron leaves reddish-brown marks that are difficult to remove. The water may taste salty or metallic. Hard water this severe can shorten the lifespan of water heaters, dishwashers, and other appliances by clogging them with scale buildup.
Testing your well is the only way to know what contaminants are actually in your water so you can treat them properly. Your well may have higher or lower levels than what is common across the county. We recommend a comprehensive metals and minerals panel, which typically costs $200 to $400. Water softeners and specialized filtration systems can address multiple contaminants at once.

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.
