Water Quality Standards

MAP's Assessment and Listing Process is driven by Vermont's State Water Quality Standards. In 2017, DEC completed a review and update of the Vermont Water Quality Standards. A triennial review of state water quality standards is required by the federal Clean Water Act. See Triennial Review below for more information.

• 2017 Vermont Water Quality Standards (current)

• 2014 Vermont Water Quality Standards (archive)

Additonal information on water quality regulations and rules may be found at the Division's Laws, Regulations and Rule page.
