Your well water comes from old limestone and dolomite rock layers buried deep underground. These rock layers sit in the ridges and valleys that run through Perry County. Water fills the cracks and hollow spaces in this carbonate rock and moves slowly through it to your well.
Lead enters your water from old metal pipes and natural deposits in the rock. Radon gas comes from tiny amounts of uranium naturally packed inside the limestone and dolomite. Sulfate dissolves directly from the rock as water sits in contact with it. Road salt from winter highway treatments also adds sodium to groundwater near major roads.
Your water is extremely hard because carbonate rock dissolves easily and releases minerals. High sulfate gives the water a bitter taste and can cause stomach problems. Iron stains sinks, toilets, and laundry orange-brown. You need treatment for lead removal and radon reduction. Have your well tested right away through a state-certified lab for a full metals panel including radon.
Lead, radon, and sulfate exceed EPA health standards in Perry County well water. This is a high-urgency situation. Your water needs testing right away. Lead is especially serious because it harms your brain and kidneys even at low levels.
Long-term exposure to radon in water releases gas into your home when you shower and use hot water. Breathing this gas increases your risk of lung cancer. Your water also has extreme iron and sulfate levels that will stain your sinks, toilets, and laundry orange and give your water a bitter taste. Scale will build up fast inside your pipes and water heater.
Get your well tested through a state-certified lab immediately. A comprehensive metals and radon panel typically costs $200–400. A whole-house treatment system combining aeration, filtering, and water softening can address these contaminants together.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
Population-level CDC data. Not individual risk prediction.
