Well owners in Liberty County should be aware of arsenic, chloride, fluoride, iron, manganese, nitrate, and radon in the groundwater. Several of these contaminants exceed EPA health standards and deserve attention.
These contaminants come from both natural sources and human activity in this coastal area. The underground rock layers naturally contain iron, manganese, and arsenic. Saltwater from the Gulf pushes inland and adds chloride to the water. Nitrate seeps in from fertilizers, septic systems, and urban development across the county.
Groundwater in Liberty County is moderately hard, driven by moderate levels of iron and sodium. The coastal lowlands geology naturally dissolves these minerals as water passes through the underground rocks. These mineral characteristics are widespread across wells throughout the county.
Wells in Liberty County commonly exceed EPA health standards for arsenic, chloride, fluoride, iron, manganese, nitrate, and radon. Arsenic can damage your kidneys and increase cancer risk over time. Chloride and fluoride at high levels can harm your health. Nitrate is especially dangerous for babies under six months old. Radon is a radioactive gas that increases lung cancer risk when breathed in over years. Manganese at elevated levels can affect your nervous system and brain development in children.
County well water is moderately hard and contains moderate iron levels. You will see rust-colored or orange staining on your laundry, dishes, and bathroom fixtures from the iron. The water may taste metallic or slightly salty. Hard water leaves scale buildup inside pipes and on faucets, and over time this mineral buildup can shorten the lifespan of water heaters and dishwashers.
Since multiple contaminants exceed health standards, we recommend a comprehensive water test that checks for metals, minerals, bacteria, and radon. Every well is different, and your well could have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your water so it can be properly treated. A comprehensive panel costs between $200 and $400. Treatment options include reverse osmosis systems, activated carbon filters, and water softeners depending on your results.

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.
