Arsenic, chloride, and fluoride are present in Evans County groundwater. All contaminant levels here are low, with none exceeding EPA health standards.
These contaminants come from natural sources in the shallow sandy and clay layers that make up the surficial aquifer system beneath the county. Rainwater percolates through the soil and picks up these minerals as it moves underground, where they occur naturally in low amounts that pose no health concern.
Groundwater in this county is moderately hard, driven by moderate calcium and magnesium from the surrounding rock and soil. The shallow aquifer system allows minerals to dissolve slowly into the water as it flows through the sandy layers. Most wells in Evans County show this same moderately hard character.
No analytes exceed EPA health standards in Evans County wells based on current county-level data. However, arsenic, chloride, and fluoride are contaminants of concern that show up in some wells in this area. Arsenic in drinking water can cause skin problems and increase cancer risk with long-term exposure. Chloride and fluoride at elevated levels also pose health concerns worth monitoring.
The moderate hardness found in county wells can leave spots on dishes and glassware after washing. You might see staining on bathroom fixtures and sinks from the mineral content in the water. Hard water can also form scale inside pipes and appliances, which shortens the lifespan of water heaters and dishwashers over time. The water may taste slightly mineral-forward or leave residue on your skin after bathing.
We recommend testing your well to find out what is actually in your water, since every well is different and your water may have higher or lower levels than the county average. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars and will check for arsenic, chloride, fluoride, and other concerns. Testing is the only way to know what treatment your specific well needs, whether that is an arsenic filter, water softening, or another solution.

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.
