Well Water in Vance County: What to Test and Why

Groundwater in Vance County contains lead, iron, chloride, arsenic, and fluoride that well owners should monitor. Several of these contaminants exceed EPA health standards, making testing and treatment important for your household.

These contaminants come from the crystalline bedrock that underlies this area. Lead and arsenic occur naturally in the rock and can dissolve into groundwater as it moves through fractures and cracks. Chloride and fluoride also leach from the minerals in this bedrock, and chloride can increase where road salt or other human activities influence shallow wells.

Groundwater in this county is moderately hard and notably high in iron, both coming from minerals in the bedrock below. The crystalline rock in this region contains iron-bearing minerals that break down slowly and release iron into the water as it flows underground. Many wells here show elevated iron levels, though the amount varies from well to well across the county.

Wells in Vance County commonly have arsenic, chloride, fluoride, iron, lead, and PFOS at levels above EPA health standards. Arsenic and lead are toxic metals that build up in your body over time and can damage your kidneys, heart, and nervous system. Fluoride at high levels can affect bone and dental health. PFOS is a chemical linked to liver problems and immune system damage. Chloride itself is not toxic at the levels found here, but its presence signals other water quality concerns.

Iron in county wells causes visible staining on sinks, toilets, and laundry. You may notice a metallic taste in your water or rust-colored discoloration. The water is moderately hard, which means soap doesn't lather well and mineral scale builds up inside pipes and on fixtures. Hard water can shorten the life of water heaters and dishwashers over time.

Testing is the only way to know what is actually in your well so you can treat it properly. Every well is different, and yours may have higher or lower levels than what is common in the county. We recommend a comprehensive metals and minerals panel, which typically costs two hundred to four hundred dollars. Water softening systems and activated carbon filters can address multiple concerns at once.
