Well Water in Denton County: What to Test and Why

Well owners in Denton County need to be aware of iron, manganese, fluoride, and PFOA in their groundwater. These contaminants are present at levels that exceed EPA health standards and warrant attention.

The rock formations beneath Denton County naturally release iron and manganese as water moves through them over time. Fluoride occurs naturally in the local bedrock and dissolves into water as it flows underground. PFOA is an industrial chemical that has entered some groundwater supplies, likely from manufacturing or waste disposal in the area.

Groundwater in this county is characterized by elevated iron and manganese, which come from the underlying rock layers. These metals dissolve naturally as water passes through the formation. Iron and manganese are found across many wells in the county, though individual well results vary.

Denton County wells commonly contain fluoride, iron, manganese, and PFOA at levels that exceed EPA health standards. Fluoride at elevated concentrations can cause dental fluorosis and skeletal problems with long-term exposure. Iron and manganese affect your nervous system and can harm children's brain development. PFOA is an industrial chemical that builds up in your body over time and has been linked to serious health effects.

Wells in this county often have elevated iron and manganese that cause orange or brown staining on clothes, fixtures, and surfaces. You may notice a metallic or unpleasant taste in the water. These minerals can also shorten the lifespan of water heaters and dishwashers by building scale inside them.

Your well is unique and may have much higher or lower levels than what is common across the county. 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, which typically costs two hundred to four hundred dollars. Reverse osmosis systems and specialized filters can remove these contaminants.
