Groundwater in Crockett County contains radon, iron, manganese, and fluoride. Several of these contaminants exceed EPA health standards, making them a concern for well owners in this area.
The rocks beneath Crockett County naturally release these elements into the water. Radon seeps from radioactive minerals in the stone. Iron and manganese leach from the sediments and rocks that make up the Pecos River Basin aquifer. Fluoride also occurs naturally in the local geology.
Groundwater in this county is very hard, driven by elevated calcium and magnesium from the minerals in the aquifer rocks below. As water moves slowly through these sand and sediment layers, it picks up dissolved minerals over time. Very hard water conditions are widespread across wells throughout the county.
Wells in Crockett County contain fluoride, iron, manganese, and radon at levels that exceed EPA health standards. Fluoride can damage tooth enamel and bones in children and adults at elevated levels. Radon is a radioactive gas that increases lung cancer risk when breathed in over time. Iron and manganese can build up in your body and affect your nervous system and organs.
The water in this county is extremely hard, which causes white scale buildup on faucets, fixtures, and inside pipes. Hard water reduces how well soap works, leaves laundry stiff, and can turn colors dull. The extreme hardness also shortens the lifespan of water heaters, dishwashers, and other appliances. You may notice a metallic taste or brown staining from the iron and manganese.
We recommend a comprehensive metals and minerals panel to find out what is actually in your well, since every well is different and yours may have higher or lower levels than the county average. Testing is the only way to know what needs treatment. A comprehensive panel typically costs between $200 and $400. Depending on your results, treatment options like water softeners, reverse osmosis systems, or specialized 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.
