Why is Barium being regulated? In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine safe levels of chemicals in drinking water which do or may cause health problems. These nonenforceable levels, based solely on possible health risks and exposure, are called Maximum Contaminant Level Goals.

BARIUM AND BARIUM COMPOUNDS 107 6. POTENTIAL FOR HUMAN EXPOSURE OVERVIEW ... fSurface water discharges, waste water treatment(metals only), and publicly owned treatment works (POTWs) (metal and metal compounds). gClass I wells, Class IIV wells, and underground injection.

Barium is an EPA regulated water contaminant. The current MCL is mg/l. Barium is highly toxic when ingested. Water treatment: Barium is readily removed by cation exchange, sodium form (water softener), and by reverse osmosis. It can also be removed by electrodialysis.

Sulfate Removal Technologies: A Review. By Mark Reinsel, ... As a polishing step for sulfate removal, barium salts can be added to precipitate barium sulfate, which has a very low solubility in water, with the final sulfate concentration limited only by the amount of barium added and reaction time. ... In Situ Sulfate Mine Water Treatment ...

Water Treatment Options. Since barium is chemically similar to calcium, it can easily be removed by ion exchange( more commonly called “softening”). Ion exchange, specifically cation exchange, basically exchanges the sodium ion for barium, calcium or other cations.

The National Primary Drinking Water Regulations (NPDWR) are legally enforceable primary standards and treatment techniques that apply to public water systems. Primary standards and treatment techniques protect public health by limiting the levels of contaminants in drinking water.

Barium chloride (10, 50, or 250 mg barium/L of drinking water) /was administered/ to young adult rats of both sexes for 4, 8, or 13 wk. Barium deposition in liver, skeletal muscle, heart, and bone was dosedependent but not related to the length of exposure.

barium is found to be present in the influent water, the treated water should be monitored periodically to verify continued performance. The water treatment equipment must be controlled diligently to ensure

Barium is a divalent cation and alkaline earth metal that can be found in naturally occurring mineral deposits. The health effects of the different barium compounds depend on how well the compound dissolves in water.

Barium is a naturally occurring element that is found in small quantities in a variety of minerals. Varying amounts of barium can be dissolved as water passes through rocks and soils and be present in …

Treating the well water Common treatment systems like carbon and sediment filters cannot adequately remove barium from drinking water. Boiling will only concentrate the barium, it will not remove it. Water treatment methods that can remove barium from drinking water include reverse osmosis, distillation,
