People living near Codorus Creek have been wondering about radon levels in the water, since the area's geology can release the gas from underground rocks. Local health officials have tested wells and springs, finding that while most samples stay safe, a few spots show higher readings that need monitoring. Residents are encouraged to test their own water and vent their homes to avoid any long-term risks from this natural source.
