Well Water in Dickenson County: What to Test and Why

Groundwater in Dickenson County contains manganese, sulfate, and arsenic. Manganese and sulfate are present at levels high enough to exceed health standards that the EPA sets for drinking water.

These contaminants come from the rock layers beneath the county. The Mississippian rock here naturally contains manganese and sulfur-bearing minerals that dissolve slowly into groundwater as water moves through the stone. Arsenic also occurs naturally in some of these rock layers. Groundwater sits in contact with these minerals for years, allowing them to build up over time.

Groundwater in this county is hard, driven mainly by sulfate and calcium minerals dissolved from the surrounding rock. The Mississippian aquifers here release these minerals as water passes through, and the hard character shows up across most wells in the county. Iron stays low in comparison, so the water does not have a strong sulfur or metallic tone from those sources alone.

Wells in Dickenson County show elevated levels of manganese and sulfate that exceed EPA health standards. Manganese can affect the nervous system with long-term exposure, especially in children, and may cause learning and behavior problems. Sulfate at high levels can cause digestive problems, particularly in infants and people with certain health conditions.

The county's moderately hard water can leave spots on dishes and glassware, create scale buildup in pipes and appliances, and reduce how well soap and shampoo work. Hard water can shorten the lifespan of water heaters and dishwashers by creating mineral deposits inside them. You may also notice a slight taste or odor difference compared to softer water.

We recommend testing your well water with a comprehensive panel to find out exactly what is in your specific well, since every well is different and yours may have higher or lower levels than the county average. Testing is the only way to know what needs treatment and what doesn't. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars. Depending on results, treatment options might include a water softener for hardness or a specialized filter for manganese removal.
