State and national drinking water standards and health guidelines

EWG Health Guideline 700 ppb

The EWG Health Guideline of 700 ppb for barium was defined by EWG as benchmark that protects against harm to the kidneys and the cardiovascular system.

EPA Maximum Contaminant
Level (MCL) 2,000 ppb

The legal limit for barium, established in 1991, was based on a 10-week study of barium exposure in 11 adult male volunteers. This limit does not include any additional consideration of children’s health.
