Well Water in Ashland County: What to Test and Why

Your well draws water from old sandstone and shale buried deep underground. This rock is thousands of feet below the surface and holds water in tiny cracks and spaces. The rock layers are thick and tightly packed, which means water moves through them very slowly.

Radon, manganese, and iron come straight from the rock itself. As groundwater sits in contact with this old stone for years, these metals and radioactive radon dissolve out of the rock and into your water. The slow movement of water through the rock gives plenty of time for this to happen. There is no surface contamination here—the problem is the bedrock chemistry.

Your water is extremely hard and loaded with minerals. You will see thick white or yellowish scale buildup on faucets, shower heads, and inside pipes and water heaters. Iron will stain sinks and laundry orange-brown. The high sodium and sulfate levels mean your water may taste salty or bitter. A water softener and an iron filter are necessary to protect your plumbing and make the water usable.

Ashland County groundwater contains radon, arsenic, manganese, iron, chloride, and sulfate at levels that exceed EPA health standards. Radon is a radioactive gas that comes from the rock itself. Arsenic and manganese are metals dissolved in the water. This is a serious, multi-contaminant problem that needs your attention right now.

Long-term exposure to manganese can harm your brain and nervous system, especially in children. Arsenic exposure over many years increases cancer risk. You will also see orange and brown staining on sinks and toilets from iron. Your water will taste metallic or bitter, and you may notice white crusty buildup from hardness and a rotten-egg smell from sulfate.

Get your well tested immediately by a state-certified lab. A basic bacteria and nitrate screen costs $50–100, but a full mineral and metals panel runs $200–400 and is essential here. Contact the Ohio Department of Health for a list of certified labs. Given multiple health threats, install a whole-house treatment system combining radon removal, arsenic filtration, and a water softener.
