Well Water in Beaufort County: What to Test and Why

Groundwater in Beaufort County contains chloride, iron, sulfate, and radon at levels high enough to exceed EPA health standards. These contaminants are present in amounts serious enough that well owners should test their water and consider treatment options.

The coastal plain geology here naturally holds these minerals and salts. Chloride and sodium come from ancient seawater trapped in the sand and clay layers underground. Iron and sulfate form where the groundwater interacts with minerals in the rock. The flat, low-lying terrain means saltwater from the Atlantic Ocean can move inland and mix with fresh groundwater in some areas.

Groundwater in this county is very hard, driven by high sodium and elevated iron and sulfate. The sand and clay layers that make up the aquifer dissolve and release these minerals as water moves through them. Most wells in Beaufort County show these characteristics, making them common across the area.

Wells in Beaufort County commonly have four contaminants that exceed EPA health standards: chloride, iron, radon, and sulfate. Chloride at high levels can be a concern for people with heart disease or high blood pressure. Radon is a radioactive gas that increases lung cancer risk when breathed in over time. Iron and sulfate themselves are not typically health hazards, but they indicate other minerals in the water that warrant attention.

The water in this county is very hard, which affects daily life at home. Hard water leaves white scale and spots on dishes, faucets, and shower doors. It makes soap less effective for cleaning and can dry out skin and hair. Very hard water also shortens the lifespan of water heaters, dishwashers, and washing machines because scale builds up inside them. Some residents notice a metallic or sulfur taste or smell in their tap water.

We recommend testing your well water through a comprehensive panel since multiple contaminants are common here. Every well is different, and yours could have higher or lower levels than what is typical for the county. 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 usually costs between two hundred and four hundred dollars. Water softeners or iron filters can address many of these concerns depending on what your test results show.
