Groundwater in Chambers County contains arsenic, chloride, iron, lead, manganese, nitrate, and sulfate at levels that exceed EPA health standards. These contaminant levels are serious enough to require well owners to test their water and consider treatment.
The coastal lowlands geology here naturally releases iron and manganese from the sediment layers underground. Saltwater from the Gulf Coast pushes inland through the porous rock, bringing chloride with it. Nitrate comes from agricultural activity and septic systems in the area. Arsenic and lead occur naturally in the rock but also concentrate where saltwater intrusion occurs.
Groundwater in this county is hard, driven by elevated calcium and magnesium dissolved from the underground sediment, and also carries moderate iron and high sodium. These minerals concentrate because the coastal sediments contain layered deposits that slowly release them as water moves through. Hard water with elevated iron and sodium is common across wells throughout the county.
Wells in Chambers County commonly contain arsenic, lead, and nitrate at levels above EPA health standards. Arsenic can damage your kidneys and increase cancer risk over time. Lead harms children's brain development and learning. Nitrate is especially dangerous for infants and can interfere with how blood carries oxygen. Manganese at elevated levels may affect the nervous system. Chloride in drinking water at high concentrations can cause health problems for people with certain conditions.
County well water is hard and contains elevated iron and sodium. Hard water leaves crusty scale buildup on pipes and faucets, reduces how well soap works, and can shorten the lifespan of water heaters and dishwashers. You may notice rust-colored or brown staining on sinks, toilets, and laundry. The water may taste salty from the high sodium content, which is a concern for people on sodium-restricted diets.
Your well may have different contamination levels than what is common in the county. We recommend a comprehensive water test that checks for metals, minerals, bacteria, and nitrate. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive panel typically costs between $200 and $400. Treatment options like reverse osmosis systems or water softeners can address multiple contaminants.

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.
