Abstract
The Illinois EPA has found 16 cities with drinking water containing barium concentrations exceeding the current state and federal drinking water standard of 1 mg/l. In addition, the presence of varying amounts of alpha activity reveal traces of radium-226 in many Illinois water wells. Increased levels of radium and barium are concurrent with a rise in cancer rates in the region. High concentrations of these toxic substances have been attributed to natural geological processes.
