This qualityassurance plan documents the standards, policies, and procedures used by the WAWSC for activities related to the collection, processing, storage, analysis, and publication of water-quality data. The policies and procedures documented in this quality-assurance plan for water-quality activities complement the quality-assurance plans for surface-water and groundwater activities at the WAWSC. </p> application/pdf 10.3133/ofr20171044 en U.S. Geological Survey Quality-assurance plan for water-quality activities in the U.S. Geological Survey Washington Water Science Center reports
