Why This Happens Here

Water in Forest County comes from old sandstone and shale layers deep underground. These rocks formed from ancient sediments and have small cracks and spaces where water sits. The layers are stacked on top of each other and hold water as it moves slowly downward.

Radon enters the water from tiny amounts of uranium scattered through the rock itself. Lead and chloride come from different sources—lead from old well pipes and fixtures that touch the water, and chloride from road salt that soaks down through the soil during winter. The fractured sandstone and shale layers allow water to pick up these elements as it flows through cracks.

The water here is very hard, meaning it contains high amounts of minerals like sulfate and sodium. Hard water leaves white scale inside pipes and on fixtures. You will notice buildup in kettles and reduced water pressure over time. The mineral load also makes soap less effective for cleaning.

What This Means for You

Your well water in Forest County contains radon, chloride, and lead at levels that exceed EPA health standards. This is a multi-contaminant situation, but the urgency level is low. The mineral content shows very high sodium and sulfate levels along with extreme hardness. You need to know what's in your water before deciding on treatment.

Long-term exposure to lead harms the brain and kidneys, especially in children. Radon in water increases cancer risk over many years. The very high sodium and sulfate levels will cause thick white scale buildup inside your pipes and fixtures, staining your laundry orange or brown, and giving your water a salty or bitter taste. This extreme hardness damages appliances and makes cleaning harder.

Call a state-certified lab and request a comprehensive metals and minerals panel that includes lead, radon, and chloride testing. Expect to pay between $200 and $400. A water softener can reduce the hardness and some contaminants, but you may need multiple treatment systems to address all three health concerns.
