2012 Recreational Water Quality Criteria

EPA has released its final 2012 Recreational Water Quality Criteria. The Agency’s new criteria reflect the latest scientific knowledge, public comments, and external peer review. They are designed to protect the public from exposure to harmful levels of pathogens while participating in water-contact activities such as swimming, wading, and surfing in all waters designated for such recreational uses.
