Summary Virginia’s final 2018 Water Quality Assessment Guidance Manual (2.4 MB Word doc) contains the assessment procedures and methods to be used for the development of Virginia’s 2018 §305(b)/ §303(d) Integrated (i.e. combined Water Quality Assessment and Impaired Waters) Report. The assessment guidance seeks to address all key elements of the U.S. Environmental Protection Agency (EPA) 2006 Assessment Guidance and subsequent updates current to December 2017, in addition to the assessment methodology for Chesapeake Bay Water Quality Standards established by EPA and adopted by Virginia (Ambient Water Quality Criteria for Dissolved Oxygen, Water Clarity, and Chlorophyll a for the Chesapeake Bay and Its Tidal Tributaries). Modifications have been made to the guidance document since 2016 (see Part II).
