Cherry Blossom Drive Federal Center, Box 25425 Portland, Oregon 97216 Denver, CO 80225 ii FOREWORD One of the great challenges faced by the Nation's water-resources scientists is providing reliable information to guide the management and protection of our water resources. That challenge is being addressed by Federal, State, Tribal, and local water-resources agencies and by academic institutions. Many of these organizations are collecting water-quality data for a host of purposes including: compliance with permits and water-supply standards; development of remediation plans for specific contamination problems; operational decisions on industrial, wastewater, and water-supply facilities; and research to advance our understanding of water-quality processes. In fact, during the past two decades, tens of billions of dollars have been spent on water-quality data-collection programs.
