Southampton County's groundwater contains arsenic, iron, and chloride. Arsenic and chloride exceed EPA health standards at concerning levels, while iron reaches moderate concentrations.
These contaminants come from the rock and sediment layers beneath the county. Arsenic and iron dissolve naturally from minerals in the sand and clay as groundwater moves through them. Chloride accumulates from seawater that penetrated inland during past geological periods and from saltwater intrusion near coastal areas.
Groundwater in this county is characterized by moderate iron content. The sandy and clay layers that make up the aquifer system release iron into the water as it flows through. Iron is present across many wells in the county, though levels vary from well to well.
Arsenic, chloride, iron, and sulfate are found at levels exceeding EPA health standards in wells across Southampton County. Arsenic is a particular concern because it builds up in your body over time and can cause serious health problems including skin damage and increased cancer risk. Iron and chloride at elevated levels can affect your health with long-term exposure. These contaminants come from natural sources in the groundwater in this area.
Iron in county well water creates reddish or brownish staining on fixtures, laundry, and surfaces. You might notice a metallic taste in your water or see discoloration when you run the tap. Iron can also clog pipes and reduce water flow over time. While the hardness and sodium levels in this county are not extreme, the iron staining is the main quality-of-life issue many well owners notice.
We recommend testing your well water with a comprehensive metals and minerals panel, which typically costs between $200 and $400. Every well is different, and your well may have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your water so you can get proper treatment if needed. Arsenic removal systems and iron filters are available options depending on your results.

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.
