Classification and Standards Unit :: Home Page

Welcome to the Classification and Standards Unit Home Page

The Classification and Standards Unit is responsible for development and implementation of the state's surface water quality standards (numeric and narrative) and surface water body classifications such as Water Supply (WS), High Quality Waters (HQW), and others; coordination of the Section's rule-making proceedings and the Environmental Management Commission's Water Quality Committee and Groundwater Committee. Groundwater quality standards are also located within the Unit.
