The purpose of the Quality Assurance/Quality Control program is to document management policies, goals, objectives and general procedures by which DEQ intends to produce and validate acceptable water quality data. Implementation of this plan within the various field and laboratory water quality monitoring and measurement program efforts will ensure that decisions made by the agency affecting the state's water quality will be based upon sound professional principles and environmental data of known and acceptable quality.
