Well Water in Bell County: What to Test and Why

Well water in Bell County contains iron, sulfate, fluoride, chloride, lead, manganese, and PFOS and PFHXS compounds. Several of these contaminants exceed EPA health standards, so well owners should test their water and know what is coming from their tap.

These contaminants come from a mix of sources in the rock below and human activity on the land above. The fluoride and some minerals dissolve naturally from the rock as water moves through it underground. Lead and PFOS can enter groundwater from old pipes, industrial sites, or other sources on the surface that have seeped down over time.

Groundwater in Bell County is very hard, driven by high levels of calcium and magnesium that dissolve from the rock below. The combination of hard water and moderate iron gives wells in this county a distinct mineral character. These characteristics are common across wells throughout the county because they come from the same rock layer that supplies water to most homes.

Wells in Bell County commonly have several contaminants above EPA health standards, including chloride, fluoride, lead, manganese, and two types of PFOS chemicals. Lead exposure harms brain development in children and can affect kidney and nervous system function in adults. Fluoride at high levels can cause dental problems and skeletal issues. Manganese can affect the nervous system and learning in children. Chloride and the PFOS chemicals are also health concerns when they exceed safe drinking water limits.

The water in this county is very hard, which means you may see white scale buildup on faucets and shower heads, staining on sinks and tubs, and soap that does not lather well. Hard water can reduce the lifespan of water heaters, dishwashers, and washing machines because mineral deposits build up inside them. You might notice a dry feeling on your skin or hair after bathing as well.

We recommend testing your well water with a comprehensive panel since several contaminants exceed health standards in the county. 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 is actually in your well so you can get the right treatment. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars and will tell you exactly what you are dealing with. Treatment options like reverse osmosis, activated carbon filters, or water softeners can address different contaminants.
