Why This Happens Here

Brooks County groundwater contains arsenic, chloride, fluoride, iron, nitrate, radon, and sulfate. Several of these contaminants exceed EPA health standards, making testing and treatment important for your household.

The coastal lowlands where Brooks County sits naturally concentrate these minerals and salts. As rain filters through the sandy and clay layers below, minerals dissolve into the water. Chloride and sulfate build up partly from saltwater influence near the Gulf Coast. Nitrate enters from agricultural activity and septic systems across the region. Radon seeps from natural radioactive minerals in the rock.

Groundwater in this county is hard and notably high in sodium, driven by calcium, magnesium, and very elevated sodium from the surrounding geology. These minerals dissolve naturally as water moves through the coastal rock layers. Most wells in Brooks County show these same hard water characteristics with elevated sodium levels.

What This Means for You

Wells in Brooks County commonly contain arsenic, chloride, fluoride, iron, nitrate, radon, and sulfate at levels above EPA health standards. Arsenic damages your kidneys and can increase cancer risk over time. Fluoride at these levels can harm bone and tooth development in children. Nitrate is especially dangerous for infants and can interfere with oxygen in the blood. Radon is a radioactive gas that increases lung cancer risk when you breathe it in.

County wells have very high sodium and hard water conditions. The sodium gives water a salty taste that many find unpleasant. Hard water leaves scale buildup on fixtures, appliances, and in pipes, and it can shorten the lifespan of water heaters and dishwashers. Iron causes rust-colored stains on laundry, sinks, and dishes. Sulfate can create a rotten egg smell in your water.

We recommend having your well tested with a comprehensive metals and minerals panel so you know exactly what is in your water. Your well could have higher or lower levels than what is common in the county, and testing is the only way to find out what treatment your family actually needs. A comprehensive panel typically costs between $200 and $400. Options like reverse osmosis systems or ion exchange can address multiple contaminants at once.

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.
