Well Water in Yates County: What to Test and Why

Groundwater in Yates County contains chloride, radon, and lead at levels that exceed EPA health standards and warrant attention. These contaminants are present at concentrations serious enough that well owners should be aware of them.

Chloride and lead enter groundwater through different routes. Chloride accumulates from road salt applied during winter and from septic systems or animal waste on the land surface. Lead leaches from old pipes and plumbing fixtures in homes and buildings. Radon comes from natural uranium decay in the limestone and other rocks beneath the county.

Groundwater in Yates County is moderately hard, driven by calcium and magnesium that dissolve from the carbonate rock below. As water percolates through limestone, it picks up these minerals naturally. Moderate iron is also present in the water. Many wells across the county show these mineral characteristics.

Chloride, lead, and radon are found at elevated levels in wells across Yates County. Chloride at high concentrations can raise blood pressure and pose risks to people with heart disease. Lead exposure harms children's developing brains and can cause learning problems and behavioral issues in young people. Radon is a radioactive gas that enters groundwater from natural uranium in rock and soil; breathing radon from water increases lung cancer risk over time.

Iron in county wells creates orange or brown staining on sinks, toilets, and laundry. You may notice a metallic taste in your water. The iron levels here are moderate, so staining and taste problems depend on your specific well's water chemistry.

We recommend testing your well with a comprehensive panel to find out exactly what is in your water, since every well is different and yours could have higher or lower levels than the county average. A full metals and minerals panel typically costs between $200 and $400. Once you know your results, treatment options like carbon filters for chloride or radon mitigation systems can address what testing reveals.
