Groundwater in Wise County contains iron, chloride, manganese, nitrate, and uranium. Several of these contaminants exceed EPA health standards and warrant attention from well owners.
The rocks beneath Wise County naturally release iron and manganese as water moves through them underground. Chloride enters groundwater from natural salt deposits in the deeper rock layers. Nitrate typically comes from fertilizers used on land above, and uranium occurs naturally in certain rock formations in this region.
Groundwater in Wise County is very hard, driven by elevated calcium and magnesium from the underlying rocks. The combination of very hard water along with moderate iron and sodium is common across wells throughout this county.
Wells in Wise County commonly have chloride, iron, manganese, nitrate, and uranium at levels that exceed EPA health standards. Uranium can damage your kidneys over time. Nitrate is especially risky for babies and young children, affecting how their blood carries oxygen. Manganese can harm the nervous system with long-term exposure. Chloride and iron also pose health concerns at elevated levels.
The very hard water in county wells will leave white scale buildup on faucets, showerheads, and inside pipes. You may notice rust-colored stains in sinks and on laundry. Hard water can shorten the lifespan of water heaters and dishwashers. Some people taste a metallic or salty flavor in their water, and the hardness makes it harder to get soap to lather.
Every well is different, and your water could have much higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your well so it can be properly treated. We recommend a comprehensive metals and minerals panel, which typically costs between two hundred and four hundred dollars. Treatment options like reverse osmosis systems or specialized filters can remove uranium and reduce other contaminants.

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.
