Human Health Ambient Water Quality Criteria

What are aquatic water quality criteria? How are health assessments interpreted and used? How is an exposure analysis conducted? Find answers to these and many other related questions on supplemental slides (pdf) from the Virtual Water Quality Standards Academy, May 2023 session.

This resource uses information from EPA's Human Health Water Quality Criteria and Methods for Toxics.

These slides are a supplement for those unfamiliar with the subject and a refresher for those with more experience. Session slides are intended to be an interim resource and do not provide the same level of training as the live WQS Academy. Visit the Water Quality Standards Academy page for more information and resources.
