Well Water in Duplin County: What to Test and Why

Groundwater in Duplin County contains iron, manganese, and nitrate at levels that exceed EPA health standards. These contaminants are present at concerning enough levels that well owners should be aware of them.

Iron and manganese dissolve naturally from the sand and clay layers that make up this region's aquifer. Nitrate often comes from fertilizer applied to farm fields and septic systems in rural areas. As water moves through the soil and rock, it picks up these substances.

Groundwater in this county is moderately hard, with elevated iron as the most notable mineral character. Iron concentrates in this area because the sandy and clay formations contain minerals that release iron as water passes through them. Elevated iron is a widespread characteristic across wells in Duplin County.

Wells in Duplin County commonly have iron, manganese, and nitrate at levels exceeding EPA health standards. Iron and manganese can cause problems with your blood and organs if you drink water with very high amounts over a long time. Nitrate is especially risky for babies and young children, as high levels can interfere with how their blood carries oxygen.

County well water with elevated iron and moderate hardness can leave rust-colored stains on sinks, toilets, and laundry. You might notice a metallic taste in the water or see buildup of scale inside pipes and on appliances. Over time, this mineral buildup can shorten the lifespan of water heaters and dishwashers.

We recommend testing your well water to find out exactly what is in it, since every well in the county is different and yours could have higher or lower levels than average. Testing is the only way to know what needs treatment. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars and will check for all three contaminants. Treatment options like iron removal systems or nitrate filters can address these specific problems.
