Barium: Occurs naturally in some limestones, sandstones, and soils in the eastern United States. Toxic oxides of nitrogen are produced in fires involving this material. Groundwater starts as precipitation, just as surface water does, and once water penetrates the ground, it continues moving, sometimes quickly and sometimes very slowly. We know now that barium occurs naturally and is an alkaline earth metal. May enter the environment from industrial discharge, mining waste, metal plating, water pipes, batteries, paints and pigments, plastic stabilizers, and landfill leachate. Imparts a bitter astringent taste to water and a brownish color to laundered clothing and plumbing fixtures. Due to resonance, the oxygens in nitrates have a partial negative charge, and the hydrogens in water have a partial positive charge.
