Affects red blood cell chemistry; delays normal physical and mental development in babies and young children. From here, barium may enter drinking water sources through surface runoff. This insoluble solid is called barium sulfate, BaSO4 . To obtain pure barium, it must be separated from naturally occurring compounds. High concentrations of dissolved solids shorten the life of hot water heaters. When conducting informational water testing, it is critical to cover a wide range of parameters to facilitate the sizing and design of a water treatment system and to determine if there are any associated water quality issues.
