Your well pulls water from broken and mixed rock layers underground. These rocks are old and cracked, which lets water seep down deep. The cracks and spaces between the rock pieces hold the water that your well reaches.
High sodium and sulfate in your water come from minerals in the rock itself. When water sits in contact with these rock layers for a long time, it dissolves the minerals out. Radon forms naturally inside the rock from radioactive material and enters your water through the cracks. Iron and manganese also come from minerals in the rock that dissolve into the groundwater.
Your water is extremely hard and loaded with minerals. The high iron means your water stains things brown and tastes metallic. The sodium and sulfate make it taste salty and can cause stomach problems. You need a treatment system and should test your well right away through a certified lab.
Your well water in Susquehanna County has multiple contaminants that exceed EPA health standards. Radon, arsenic, manganese, iron, and chloride are all present at unsafe levels. This is a serious situation that needs your attention right away.
Long-term exposure to radon increases lung cancer risk. Arsenic and manganese can harm your nervous system and brain development in children. The extremely high iron and mineral content will stain your clothes and fixtures, leave brown spots, and create scaling buildup in pipes. Your water likely tastes salty from high sodium and sulfate levels.
You need a certified lab test immediately. A comprehensive metals and minerals panel from a state-certified lab costs $200–400 and will give you exact results. A whole-house treatment system combining aeration, filtration, and reverse osmosis can address multiple contaminants at once.
