What are the health effects associated with barium in drinking water?

EPA has found barium to potentially cause gastrointestinal disturbances and muscular weakness when people are exposed to it at levels above the maximum contaminant level (MCL) of 2 ppm for relatively short periods of time. In addition, barium has the potential to cause high blood pressure from a lifetime exposure at levels above the MCL.
