Your well water comes from hard crystalline rock deep underground. This rock is old granite and gneiss, broken up by cracks and fractures. Water fills these tiny spaces between the rock pieces and moves through them slowly. Wells in this area tap directly into these fractured rocks.
Lead, nitrite, and radon enter the water from the rock itself and from land use above. Lead dissolves as water passes through old pipes and mineral deposits in the fractured bedrock. Radon forms naturally when tiny amounts of uranium in the crystalline rock break down. Nitrite comes from septic systems and fertilizers soaking down through soil into the groundwater. The fractured rock lets contaminants move downward without much filtering.
Your water is extremely hard and loaded with minerals. Iron reaches 130 parts per million, sodium hits 30,000 parts per million, and sulfate reaches 35,500 parts per million. These high mineral levels mean thick white scale on fixtures, rust stains in sinks and laundry, and a salty taste. You need a water test and a treatment system designed for multiple heavy metals and radon removal.
Your well water in Montgomery County shows lead, nitrite, and radon all exceeding EPA health standards. This is a serious situation that demands immediate action. Multiple contaminants at harmful levels create real risks for your family's health.
Long-term exposure to lead damages children's brains and nervous systems. Nitrite reduces oxygen in the blood, especially in infants. Radon in water releases radioactive gas into your home, raising lung cancer risk. The extremely high sodium, iron, and sulfate also mean your water will stain sinks and laundry orange, leave crusty white scale on pipes and fixtures, and taste salty and bitter.
Call a state-certified lab right now and order a comprehensive metals and radon panel—expect to pay $200 to $400. Do not delay. A whole-house treatment system combining activated carbon, ion exchange, and aeration can address these contaminants, but you need your test results first to design the right system for your home.
