Why This Happens Here

Groundwater in Glynn County contains arsenic, chloride, iron, manganese, nitrate, radon, and sulfate at levels that exceed EPA health standards. Several of these contaminants reach concerning levels in your county's wells.

The shallow sandy layers that hold your county's water sit close to the ocean and coastal areas. Salt water seeps into the ground naturally, bringing chloride and sulfate. Radon comes from radioactive minerals in the soil and rock. Nitrate enters from septic systems and fertilizer. Arsenic and manganese occur naturally in the rock and sediment that make up your aquifer.

Groundwater in this county is very hard, driven by elevated sulfate and very high hardness levels. The sandy and clay layers that make up your aquifer contain minerals that dissolve into the water as it flows through. These mineral-rich characteristics show up across most wells throughout the county.

What This Means for You

Wells in Glynn County commonly contain arsenic, nitrate, radon, and manganese at levels above EPA health standards. Arsenic can damage organs and increase cancer risk over time. Nitrate is especially dangerous for infants and can interfere with how blood carries oxygen. Radon is a radioactive gas that increases lung cancer risk. Manganese at high levels can harm the brain and nervous system.

The water in this county is very hard, which means it leaves white scale buildup on faucets, shower heads, and inside pipes. Hard water makes soap work poorly and leaves spots on dishes and glassware. Your water heater, dishwasher, and other appliances wear out faster because of the mineral buildup. You may also notice a rotten-egg smell or bitter taste from sulfate in the water.

We recommend testing your well with a comprehensive panel since multiple contaminants exceed health standards in county wells. Every well is different, and yours could have much higher or much lower levels than what is common here. Testing is the only way to know what is actually in your water and how to treat it properly. A comprehensive panel typically costs between two hundred and four hundred dollars. Treatment options range from point-of-use filters to whole-house systems 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.
