Why This Happens Here

Your well water comes from old limestone and dolomite rock deep underground. This rock sits hundreds of feet below the surface and has tiny cracks and fractures that hold water. The same rock type runs under all your neighboring counties too.

Iron, manganese, and arsenic dissolve out of the rock itself as groundwater slowly sits in contact with it. These metals are naturally embedded in the stone and release into the water in low-oxygen conditions underground. The rock does not protect against these metals—they are part of the stone.

Your water is extremely hard and loaded with minerals. You will see thick white crusty buildup on faucets and inside pipes. Iron will stain your sinks and laundry orange or brown, and the high sodium and sulfate will affect how your water tastes and smells.

What This Means for You

Arsenic in Greene County well water exceeds EPA health standards. This is a serious health concern that demands testing right away. Arsenic is colorless and odorless, so you cannot tell it is there without a lab test. Your family's health depends on knowing whether your well has arsenic in it.

Long-term exposure to arsenic can cause serious illness. The extremely high iron, sodium, and sulfate levels will also create daily problems. You will see rust-colored stains in sinks and on laundry. Your water will taste metallic and unpleasant. Pipes and water heaters will clog and fail faster than normal.

Call a state-certified lab today and ask for testing that includes arsenic, iron, manganese, and bacteria. A basic health screen runs $50–100, but given the multiple contaminants here, a comprehensive metals panel for $200–400 is worth the cost. A whole-house treatment system designed for arsenic removal combined with water softening can address these problems.
