Barium
Alkaline metal that occurs in nature as a mineral found in many different compounds
Health Guideline Level (HGL)
2 ppb
Maximum level that poses minimal health risk based on the latest science
Health Effects
The EPA drinking water limits for barium are based on adverse effects to kidneys observed in animal studies. Exposure to high doses of barium is shown to have cardiovascular health effects, including changes to heart rate and blood pressure, muscle weakness and paralysis. Several human studies have investigated a possible link between exposure to low levels of barium and changes to blood pressure and cardiac rhythms, but evidence is still currently inconclusive.
Affected Organs & Systems:
Common Sources
- Occurs naturally in most surface and groundwaters
- Barium compounds can also enter the environment through emissions and waste streams from barium-intensive industries like oil and gas drilling, electronics manufacturing, and textiles
How to Remove It
Water filters certified under the following NSF standards are effective at removing Barium:
Health Guideline Level
The HGL represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Barium is classified as a Metals contaminant.
This contaminant primarily affects the kidneys, cardiovascular.
