Well Water in Ector County: What to Test and Why

Groundwater in Ector County contains arsenic, fluoride, iron, manganese, nitrate, and uranium at levels that exceed EPA health standards. Several of these contaminants are present at concentrations the EPA considers concerning enough to regulate.

These contaminants come from natural sources in the rock and soil layers beneath the county. Arsenic, uranium, and iron occur naturally in the underground materials that make up the High Plains aquifer in this region. Nitrate can enter groundwater from agricultural and industrial activities on the land above. Fluoride also occurs naturally in the local geology.

Groundwater in Ector County shows moderate iron content along with naturally occurring arsenic, uranium, and fluoride from the rock formations below. The High Plains aquifer in this area passes through rock and sediment layers that contain these minerals, and water moving through them picks up these elements over time. Wells across the county show these characteristics at varying levels, reflecting differences in depth and local geology.

Wells in Ector County can contain arsenic, fluoride, iron, manganese, nitrate, and uranium at levels above EPA health standards. Arsenic and uranium are radioactive metals that build up in your body over time and increase cancer risk. Fluoride at high levels can damage tooth enamel and bones. Nitrate is especially dangerous for babies and can interfere with oxygen in the blood. Manganese affects the nervous system with long-term exposure.

Iron and manganese in county well water create staining on fixtures, laundry, and dishes that is hard to remove. You might notice a metallic or unpleasant taste in your drinking water. Iron can leave rusty-colored buildup in pipes and reduce water flow over time.

We recommend testing your well water with a comprehensive panel that checks for metals, minerals, and bacteria, since every well in this county is different and yours could have higher or lower levels than what is common here. Testing is the only way to know exactly what is in your water so you can treat it properly. A comprehensive panel typically costs between $200 and $400. Depending on what testing shows, treatment options like reverse osmosis systems or whole-house filters can remove most of these contaminants.
