Well Water in Greene County: What to Test and Why

Your well taps into old sandstone and shale rock layers that formed in ancient swamps and contain coal seams. These rocks are broken up by cracks and fractures that let water seep through slowly. The layers sit deep underground beneath thick soil and clay.

The minerals showing up in your water come from the rock itself breaking down over time. Iron and manganese are naturally present in these coal-bearing rock layers and dissolve into the water. Sulfate appears where water moves through layers that contain coal and mineral deposits. The depth of your well and the slow movement of water through cracked rock give contaminants time to build up as the water sits in these formations.

Your water is very hard and contains high amounts of minerals from the rock. The high iron will stain your laundry and fixtures orange-brown. You will see scale buildup in pipes and appliances, and soap will not lather well. A whole-house filter or water softener system can help manage these mineral levels.

Greene County wells are pulling water through rock layers that contain iron, manganese, and sulfate at elevated levels. Iron and manganese exceed EPA health standards in this area. Sulfate also exceeds its limit in a significant number of tested wells. These findings warrant getting your own well tested to know what you're drinking.

Long-term exposure to manganese can affect how your brain and nervous system work, especially in children. Iron stains laundry, fixtures, and teeth brown or orange. It makes water taste metallic and cloudy. High sulfate levels can cause digestive issues and give water a rotten-egg smell. Your water also shows extreme hardness, which means scale buildup will happen fast inside pipes and appliances.

Get a certified lab test from a state-certified lab to find out what's in your well—a comprehensive mineral and metals panel runs $200–400. A basic health screen for bacteria and nitrate costs $50–100. A water softener or iron filter can help reduce staining and scale buildup.
