Well Water in Wise County: What to Test and Why

Groundwater in Wise County contains manganese, sulfate, and arsenic. Manganese and sulfate exceed EPA health standards in this county's wells, which means well owners should test their water and consider treatment options.

The rock layers beneath Wise County are ancient and naturally contain these minerals. Manganese and arsenic come from the Mississippian-aged rock itself, while sulfate builds up as water moves slowly through the stone. This is a geology problem, not a pollution problem from human activity on the surface.

Groundwater in this county is moderately hard and carries moderate amounts of sulfate. The moderately hard water comes from minerals dissolved out of the local rock as rainwater seeps down. Most wells in Wise County show these same mineral patterns because the water comes from the same underground rock formation.

Wells in Wise County commonly have manganese and sulfate at levels that exceed EPA health standards. Manganese can affect the nervous system with long-term exposure, especially in children, and may impact learning and behavior. Sulfate can cause digestive problems like diarrhea, particularly in infants and people with sensitivities.

The moderate hardness in county wells and higher sulfate levels can create some quality-of-life issues. You might notice a bitter or salty taste in your water, or see staining on fixtures and laundry. The hardness can also build up scale inside pipes and appliances over time.

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 water could have higher or lower levels than what is common in the county. Testing is the only way to know exactly what is in your well so you can treat it properly. A water softener or sulfate-removal system can help address these concerns.
