FOREWORDThe U.S. Geological Survey (USGS) is committed to
serve the Nation with accurate and timely scientific infor mation that helps enhance and protect the overall quality of life, and facilitates effective management of water, biologi cal, energy, and mineral resources. Information on the qual ity of the Nation's water resources is of critical interest to the USGS because it is so integrally linked to the long-term availability of water that is clean and safe for drinking and recreation and that is suitable for industry, irrigation, and habitat for fish and wildlife. Escalating population growth and increasing demands for the multiple water uses make water availability, now measured in terms of quantity and quality, even more critical to the long-term sustainability of our communities and ecosystems.
The USGS implemented the National Water-Quality Assessment (NAWQA) Program to support national, regional, and local information needs and decisions related to water-quality management and policy. Shaped by and coordinated with ongoing efforts of other Federal, State, and local agencies, the NAWQA Program is designed to answer: What is the condition of our Nation's streams and ground water? How are the conditions changing over time? How do natural features and human activities affect the quality of streams and ground water, and where are those effects most pronounced? By combining information on water chemis try, physical characteristics, stream habitat, and aquatic life, the NAWQA Program aims to provide science-based insights for current and emerging water issues. NAWQA results can contribute to informed decisions that result in practical and effective water-resource management and strategies that protect and restore water quality.
Since 1991, the NAWQA Program has implemented interdisciplinary assessments in more than 50 of the Nation's most important river basins and aquifers, referred to as Study Units. Collectively, these Study Units account for more than 60 percent of the overall water use and popu lation served by public water supply, and are representative of the Nation's major hydrologic landscapes, priority eco logical resources, and agricultural, urban, and natural sources of contamination.
Each assessment is guided by a nationally consistent study design and methods of sampling and analysis. The
assessments thereby build local knowledge about water- quality issues and trends in a particular stream or aquifer while providing an understanding of how and why water quality varies regionally and nationally. The consistent, multi-scale approach helps to determine if certain types of water-quality issues are isolated or pervasive, and allows direct comparisons of how human activities and natural pro cesses affect water quality and ecological health in the Nation's diverse geographic and environmental settings. Comprehensive assessments on pesticides, nutrients, vola tile organic compounds, trace metals, and aquatic ecology are developed at the national scale through comparative analysis of the Study-Unit findings.
The USGS places high value on the communication and dissemination of credible, timely, and relevant science so that the most recent and available knowledge about water resources can be applied in management and policy deci sions. We hope this NAWQA publication will provide you the needed insights and information to meet your needs, and thereby foster increased awareness and involvement in the protection and restoration of our Nation's waters.
The NAWQA Program recognizes that a national assessment by a single program cannot address all water- resource issues of interest. External coordination at all lev els is critical for a fully integrated understanding of water sheds and for cost-effective management, regulation, and conservation of our Nation's water resources. The Program, therefore, depends extensively on the advice, cooperation, and information from other Federal, State, interstate, Tribal, and local agencies, non-government organizations, industry, academia, and other stakeholder groups. The assistance and suggestions of all are greatly appreciated.

Selected Data From Field Studies of Pesticide Runoff to Surface Waters
Paul D. Capel, Thomas A. Winterstein, and Steven J. Larson
ABSTRACT
Citations from the scientific literature for studies that quantified selected pesticides in field runoff or streams were obtained from two computerized bibliographic databases: Chemical Abstracts and AGRICOLA. Selected data were extracted from studies in field environments that lasted longer than a day and are summarized here. The data extracted from each article, if available, include pesticide infor mation, environmental setting, year of study, and the mass of the pesticide in runoff as a percent of the mass applied. Data from two national studies of pesticides in surface waters done by the U.S. Geological Survey (National Water-Quality Assessment Program, 1992-1995, and National Stream-Quality Accounting Network, 1996-1998) also are summarized.
INTRODUCTION
Contamination of surface waters by pesticides is a topic of current national and international concern. One of the important sources of pesticides to surface waters is rain- or irrigation-induced runoff. The important processes that govern runoff were reviewed previously by Wauchope (1978), Weber and others (1980), Wauchope and Leonard (1980a,b), Leonard (1988,1990), and Willis and McDowell (1982). Leonard (1990), in his review identified four general factors that govern the extent of pesticide runoff: climate, soil, chemical properties, and management practices.
To facilitate current and future research on pesticides in surface waters, specifically for the U.S. Geological Survey's National Stream-Quality Accounting Network (NASQAN) program (Hooper and others, 1997), a search of the scientific literature for studies that quantified selected pesticides (see table 1 in back of report) in field runoff or streams was performed by means of two computerized bibliographic databases: Chemical Abstracts and AGRICOLA. This report summarizes data for the pesticides listed in table 1 (back of report). Only those data from published articles that contained information essential to the calculation of the pesticide mass in runoff as a percentage of the mass applied are included. The data extracted from each literature article, if available, include pesticide information, environmental setting (area, soil type, location, land use, and type of precipitation), year of study, and the mass of the pesticide in runoff as a percentage of the mass applied. The extracted data are summarized in table 2 (back of report). Furthermore, only the data from studies that were conducted in field environments and that lasted more than one day were included.
This report also summaries recent NAWQA (mostly 1992-1995) and NASQAN (1996-1998) data on the loads of pesticides in surface waters and the loads as a percentage of their estimated use. The concentration data are available elsewhere (National Water-Quality Assessment, 2000; Hooper and others, in press).
CALCULATION OF PESTICIDE LOADS
Pesticide loads for streams sampled in the NAWQA and NASQAN programs were calculated by summing estimated daily loads as described in Larson and others (1999). The daily loads were calculated by multiplying the daily stream discharge by the daily concentration. Stream discharge was measured daily, while pesticide concentrations were measured less frequently. Pesticide concentrations for days that were not sampled were

estimated by linear interpolation using concentrations measured on the closest preceding and following days in which pesticides were quantified. Only pesticides with use greater than 1 kilogram per square kilometer of total watershed area were included.
