Barium

GENERAL INFORMATION
Barium is a lustrous, machinable metal which exists in nature only in ores containing mixtures of elements. The major sources of barium in drinking water are discharge of drilling wastes; discharge from metal refineries; and erosion of natural deposits.

HEALTH EFFECTS
Some people who drink water containing barium in excess of the MCL over many years could experience an increase in their blood pressure.
