, from USGS and other publications, from other (unpublished) documents, from formal presentations by USGS staff, from analyses of NWUIP data, from discussions with water use specialists in various USGS districts, and from discussions with agency specialists in other USGS resource evaluation programs.

The committee has been impressed by the increasing availability of national geospatial information on water resources, attributable to efforts of the USGS and other federal agencies to convert tabular data inventories describing water facilities into mapped locations with attached attributes. This activity makes possible "place-based" or "location-based" analysis in which georeferenced data from disparate sources are synthesized into an integrated database that can support more comprehensive study than can the separate data sources taken alone.

The natural water system coexists with the infrastructure water system, described by locations of water withdrawals and discharges, and by the principal water facilities (pumping stations, treatment plants, water conveyance systems) through which water is moved through the landscape in constructed water systems.

water resource assessments in which the relationship between water use and availability of water is examined for particular aquifers or watersheds, or the impact of water use on water quality and environmental conditions is studied for particular regions. DEFINITIONS OF "WATER USE" AND RELATED CONCEPTS In this section, we briefly define terms that are commonly used in the USGS water use summary reports.

Chapter 6 examines indirect estimation using linear regression models that quantify the relationships between aggregated state-level water use data from the NWUIP and corresponding demographic, economic, and climatic data. Chapter 7 reviews how the water use data and estimation procedures presented in previous chapters can be used to provide integrated water use information.

INTRODUCTION 15 This approach has the potential to answer questions about the consequences of water use on the natural water system and associated aquatic ecosystem, and it has the potential to evaluate whether the quantity and quality of water are sufficient for specific water use purposes. Finally, Chapter 9 presents the conclusions of the committee's study.
