State, National, and Health Guidelines for Drinking Water
EWG Health Guideline: 1,500 ppb
The EWG Health Guideline of 1,500 ppb for strontium was defined by the Environmental Protection Agency as a benchmark for testing under the Unregulated Contaminant Monitoring Rule program. This health guideline protects against harm to bones.
