Groundwater in Chambers County contains arsenic, chloride, iron, lead, manganese, nitrate, and sulfate at levels that exceed EPA health standards. These contaminants are present at concentrations high enough that well owners need to test their water and take action if levels are elevated in their own wells.
The coastal location and underground geology of this area naturally concentrate these contaminants. Saltwater from the Gulf pushes inland through sandy and clay layers, bringing chloride and other salts deeper into the groundwater. Iron and manganese come from the rock itself and build up over time as water sits underground. Nitrate comes from fertilizer, septic systems, and other sources on the land surface that seep down into the water below.
Groundwater in this county is hard, driven by elevated calcium and magnesium from the limestone and clay layers below. Iron is present at moderate levels throughout the area. Sodium is notably high, a result of saltwater influence from the nearby coast mixing with the freshwater aquifer. These mineral characteristics are widespread across wells in Chambers County.
Wells in Chambers County commonly have arsenic, lead, nitrate, and manganese above EPA health standards. Arsenic exposure over time raises cancer risk and can harm your kidneys and nervous system. Lead damages children's brain development and learning ability, even at low amounts. Nitrate is dangerous for babies under six months and can cause serious illness. Manganese at high levels can affect how your brain and nerves work.
Hard water in county wells causes white scale buildup on faucets and in pipes, staining fixtures and reducing water flow. You'll notice spots on dishes and glassware after washing. Hard water shortens the lifespan of water heaters and dishwashers by years. The water may taste slightly off or feel slippery on your skin.
We recommend getting a comprehensive water test right away since multiple contaminants exceed health standards in this county. Every well is different--yours could have higher or lower levels than what is typical here. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars and will tell you exactly what you're dealing with. Treatment options like reverse osmosis, ion exchange, or activated carbon can address these concerns depending on what your test shows.

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.
