Well Water in Gloucester County: What to Test and Why

Groundwater in Gloucester County contains iron, chloride, radon, and sulfate at levels that exceed EPA health standards. These contamination levels are serious enough that well owners should test their water and consider treatment options.

These contaminants come from both natural and human sources in the area. Iron and radon occur naturally in the coastal plain rocks beneath the county. Chloride enters groundwater from saltwater that moves inland from the ocean, especially in low-lying areas near the coast, and from road salt used during winter months.

Groundwater in this county is moderately hard and notably high in sodium and iron. The coastal plain rock contains minerals that dissolve slowly into water, releasing sodium, iron, and calcium into wells. These characteristics are common across the county's wells, though levels vary from one location to another depending on depth and proximity to the coast.

Wells in Gloucester County commonly contain chloride, iron, radon, and sulfate at levels that exceed EPA health standards. Radon is a radioactive gas that can increase the risk of lung cancer over time. Chloride at elevated levels can be a concern for people on restricted sodium diets and those with certain health conditions. Iron and sulfate can affect how your body processes certain minerals and medications.

County well water tends to be moderately hard with high iron content, which creates visible staining on fixtures, laundry, and dishes. The elevated sodium in wells here can affect the taste of your water and may be a concern for people watching their salt intake. Hard water can also reduce the lifespan of water heaters and dishwashers by building up scale inside the appliances.

Testing is the only way to know what is actually in your well, since every well in the county is different and yours may have higher or lower levels than average. We recommend a comprehensive water quality panel to check for metals, minerals, bacteria, and contaminants. A full panel typically costs between $200 and $400. Treatment options like radon removal systems, water softeners, and iron filters can address these concerns once you know your specific levels.
