Ground and Surface Water Quality Information
Water quality standards provide protection and preservation of the waters of the state.
Along with regulations, monitoring helps Ecology to keep track of how well water cleanup plans and best management practices are working to help water bodies meet and maintain water quality standards. Water reclamation and reuse helps Washington efficiently use its waters.

Water Quality Monitoring Information
Ecology monitors water quality in streams; rivers; and other water bodies for a number of reasons. Some monitoring provides data on the condition of a water body and establishes trends in its environmental health. Monitoring also tracks the success and usefulness of best management practices (BMPs) for water cleanup. Monitoring is also used to determine whether water bodies are meeting state water quality standards.
