CC-15-009: EPA – Water – Final Recommendations – Updated Ambient Water Quality Criteria for the Protection of Human Health

In the June 29, 2015, edition of the Federal Register, EPA issued final recommended, human health-based, ambient water quality criteria for 94 substances. EPA had issued draft updated criteria in May of 2014. The updated criteria reflect revisions to parameters used for criteria derivation, in particular, parameters representing consumption of contaminated water and fish obtained from ambient waters.
