Your well water comes from mixed rock layers underground. These rocks are not the clean sandstone you find in neighboring counties. Instead, they hold water in spaces between different types of rock and soil. This mixture creates the water chemistry you deal with.
The contaminants you see come straight from the rocks themselves. Manganese, iron, and sulfate dissolve naturally as water sits in contact with these layers over time. Chloride also appears because of road salt that seeps down from highways and roads above. The rock composition does not filter these out the way cleaner sandstone layers do.
Your water is heavily loaded with minerals. Sulfate reaches 36,000 mg/L, which is extremely high and gives water a bitter taste and smell. Sodium at 9,000 mg/L makes the water taste salty. Iron at 220 mg/L will stain your sinks, toilets, and laundry orange or brown. You need treatment to use this water for cooking and drinking.
Your well water in Branch County has iron, manganese, and chloride at levels that exceed EPA health standards. This is a serious concern that needs your attention right away. The high mineral content means your water requires testing and likely treatment before your family drinks it.
Long-term exposure to manganese can harm brain development in children and affect how adults think and move. Iron stains sinks, toilets, and laundry orange or brown. High sulfate and sodium give water a salty or bitter taste and can cause stomach problems. These minerals also build up inside pipes and damage water heaters.
Get your well tested by a state-certified lab immediately. A basic health screen costs $50–100, while a comprehensive mineral and metals panel runs $200–400. A whole-house treatment system with oxidation and filtration can remove iron and manganese from your water.
