Well Water in Tioga County: What to Test and Why

Your well water comes from old sandstone and shale rock layers underground. These rocks are broken and cracked, which lets water flow through them. The rock in Tioga County is different from the smoother limestone layers that sit below neighboring counties to the north and west.

Lead and arsenic come from the rock itself. These metals sit naturally in the sandstone and shale where your water flows. Iron dissolves out of the rock as water moves through it. The fractured nature of this rock also means contamination can reach wells more easily than in solid limestone areas.

Your water is extremely hard because of dissolved minerals in the rock. The high iron content—100 mg/L—will stain your sinks, laundry, and fixtures orange-brown. You will notice white scale buildup on faucets and inside pipes from the mineral load. This hardness and iron require treatment to protect your plumbing and appliances.

Your well water in Tioga County has arsenic and lead at levels that exceed EPA health standards. Iron also exceeds what EPA recommends. These are serious contaminants that need immediate action. Your water quality is a high-priority concern.

Long-term exposure to arsenic increases cancer risk and can harm your kidneys and nervous system. Lead damages brain development in children and affects learning and behavior. The very high iron in your water will stain sinks, toilets, and laundry orange-brown and leaves a metallic taste. Your water is extremely hard, which causes white scale buildup on pipes and fixtures.

Get your well tested by a state-certified lab right away. A comprehensive metals and minerals panel costs $200–400 and will confirm what you're dealing with. A whole-house treatment system combining reverse osmosis and iron removal can address these contaminants, but you need your test results first to choose the right system.
