Source of BariumBarium (Ba+2)is a naturally occurring alkaline earth metal found primarily in the Midwest. Traces of the element are found in surface and ground waters. It can also be found in oil and gas drilling muds, waste from coal fired power plants, jet fuels, and automotive paints. Barium is highly toxic when its soluble salts are ingested. The current MCL for Barium is 2.0 mg/l.
Treatment of BariumSodiumform cation exchange units (softeners) are very effective at removing Barium. Reverse Osmosis is also extremely effective in its removal, as well as Electrodialysis.
