Well Water in Southampton County: What to Test and Why

Southampton County's groundwater contains manganese, fluoride, iron, chloride, nitrate, and sulfate. Several of these contaminants exceed EPA health standards, making them worth your attention.

These contaminants come from the sandy and clay layers that make up the aquifer here. As water moves slowly through these sediments, it picks up minerals and salts naturally present in the rock. Chloride and sulfate accumulate where saltwater influence reaches inland from the coast. Iron and manganese dissolve from minerals in the sand and clay.

Groundwater in this county is soft and notable for elevated sodium and moderate iron. Sodium accumulates in the water as it moves through the sandy sediments, while iron dissolves naturally from minerals in the surrounding rock. These characteristics show up in many wells across the county.

Wells in Southampton County commonly exceed EPA health standards for chloride, fluoride, iron, manganese, nitrate, and sulfate. Chloride at elevated levels can harm people with high blood pressure or heart disease. Fluoride above recommended levels during childhood can cause dental fluorosis, which creates white spots on teeth. Nitrate is especially dangerous for infants and can prevent their blood from carrying oxygen. Iron and manganese at high levels can affect the brain and nervous system over time.

County well water has high sodium content, which adds a salty taste to drinking water and is a concern for people watching their sodium intake. The moderate iron levels create reddish or brownish stains on sinks, toilets, and laundry. You may also notice a metallic or bitter taste. Since wells here are soft, scale buildup is less of a problem than in harder-water counties, so appliances should not suffer shortened lifespans from mineral deposits.

We recommend a comprehensive metals and minerals panel to understand what is actually in your well, since every well is different and your water could have higher or lower levels than what is common in the county. Testing is the only way to know what treatment your specific well needs. A comprehensive panel typically costs between $200 and $400. Depending on results, treatment options like ion exchange filters or reverse osmosis systems can address multiple contaminants.
