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.
Some people who drink water containing barium in excess of the MCL over many years could experience an increase in their blood pressure.
MCL ADVISORY - ACTION IS HIGHLY RECOMMENDED
Barium levels were detected in your water sample to exceed the maximum contaminant level (MCL).
ACTION IS OPTIONAL
Barium levels were detected in your water sample but do not exceed the maximum contaminant level.
