Abstract
The U.S. Geological Survey (USGS) was one of numerous governmental agencies, private organizations, and the academic community that provided data and interpretations for the U.S. Environmental Protection Agency’s (USEPA) 2007 Report on the Environment: Science Report. This report documents the sources of data and methods used to develop selected water–quality indicators for the 2007 edition of the report compiled by USEPA. Stream and ground–water–quality data collected nationally in a consistent manner as part of the USGS’s National Water–Quality Assessment Program (NAWQA) were provided for several water–quality indicators, including Nitrogen and Phosphorus in Streams in Agricultural Watersheds; Pesticides in Streams in Agricultural Watersheds; and Nitrate and Pesticides in Shallow Ground Water in Agricultural Watersheds. In addition, the USGS provided nitrate (nitrate plus nitrite) and phosphorus riverine load estimates calculated from water–quality and streamflow data collected as part of its National Stream Water Quality Accounting Network (NASQAN) and its Federal–State Cooperative Program for the Nitrogen and Phosphorus Discharge from Large Rivers indicator.
