ABSTRACT

Cover photograph: U.S. Geological Survey Hydrologic Technician making a streamflow measurement from the Georgia Highway 124 bridge over the Yellow River.The U.S. Geological Survey (USGS), Water Resources Discipline, has a policy that requires each Water Science Center (WSC) to prepare a Surface-Water Quality-Assurance Plan. The plan for each WSC describes the policies and procedures that ensure high quality in the collection, processing, analysis, computer storage, and publication of surface-water data. The USGS Georgia Water Science Center (GWSC) Surface-Water Quality-Assurance Plan documents the standards, policies, and procedures used by the GWSC for activities related to the collection, processing, storage, analysis, and publication of surface-water data.
