Your well draws water from old limestone and dolomite rock buried deep underground. This rock is hundreds of millions of years old and sits beneath a protective layer of glacial clay left behind by ancient ice sheets. Water seeps slowly through tiny cracks and spaces in the limestone where it collects and stays.
The geology here protects your water naturally. The thick clay layer above acts like a shield that blocks pollution from farms and roads from soaking down into the rock. No harmful contaminants show up in testing for this area, which means the limestone and clay are doing their job.
The water from this rock is hard and contains minerals like iron and sulfate. You may notice white crusty buildup on faucets and fixtures, or rust-colored staining on sinks and laundry. A water softener can solve the hardness problem and make your water easier to use every day.
The water in Union County does not have any contaminants detected at levels that exceed EPA health standards. Testing shows no harmful chemicals or bacteria present in the area's groundwater. This is good news for your well water quality.
Since no contaminants exceed health standards, there are no long-term health effects to worry about from the water itself. The routing data suggests sediment and iron may be present, but specific levels were not provided in the testing results. If you notice any staining, cloudy water, or odd taste or smell, those could point to mineral content worth checking.
Get your well tested by a certified lab to confirm what is actually in your water and rule out any issues. A basic health screen for bacteria and nitrate typically costs $50–100. If you see any signs of iron or sediment problems, ask the lab to measure those as well.
