Groundwater in Bowie County contains iron, manganese, and fluoride that well owners should be aware of. These three contaminants exceed EPA health standards, making them the most concerning water quality issue in this area.
The rock beneath Bowie County naturally contains minerals like iron and manganese that dissolve into groundwater as water seeps down through the soil and stone. Fluoride enters the water the same way, leaching from minerals in the rock layers below. Over time, as water moves slowly through the ground, it picks up more and more of these dissolved minerals.
Groundwater in this county is very hard, driven mainly by calcium and magnesium that come from the rock formation here, combined with high levels of sodium. The rock and sediments in this area release these minerals into water as it passes through, and the slow movement of groundwater means minerals accumulate to elevated amounts. These hard-water and high-sodium conditions are widespread across wells throughout the county.
Fluoride, iron, and manganese are found at levels exceeding EPA health standards in wells across Bowie County. Fluoride at elevated levels can affect bone health and tooth development in children. Iron and manganese at high concentrations can cause problems with blood and organ function over time. These contaminants deserve attention even though they are not immediately dangerous.
Wells in this county are extremely hard, which means you will likely see scale buildup on faucets and inside pipes. Hard water can shorten the lifespan of water heaters, dishwashers, and other appliances. The high sodium content in county groundwater combined with the iron and manganese can create staining on laundry, sinks, and fixtures. You may also notice an unpleasant taste or odor in the water.
We recommend a comprehensive metals and minerals panel to find out what is actually in your well, since every well is different and your water could have higher or lower levels than what is common here. Testing is the only way to know what needs to be treated and how to do it right. A comprehensive panel typically costs between $200 and $400. Treatment options like water softeners and iron removal filters can address multiple problems 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.
