About The Study: In this cohort study of birthing parent–infant dyads across the U.S., arsenic measured in public water systems was associated with birth outcomes at levels below the current U.S. Environmental Protection Agency’s maximum contaminant level. The findings suggest that further reducing the maximum contaminant level for arsenic may decrease the number of infants with low birth weight in the U.S.
