Charles Crawford is a Scientist Emeritus (Hydrologist) with the U.S. Geological Survey (USGS), Ohio-Kentucky-Indiana Water Science Center (OKI WSC)
As a Scientist Emeritus he advises staff from the OKI WSC and USGS Water Mission Area on use of statistical methods for data analysis and is developing an approach for estimating uncertainty in stream temperature measurements. Charles joined the USGS in 1978 and has worked on a variety of water-quality investigations since. Prior to his retirement he was the Coordinator for Data Analysis and Statistics in the USGS Water Resources Mission Area, Earth System Processes Division, Water Resources Assessment Branch. Prior to that position he managed the USGS National Water Quality Assessment Project (NAWQA) and National Stream Quality Accounting Network (NASQAN) stream quality monitoring networks, a position he held from 2005 to 2015. From 2000 to 2005 he was a member of the NAWQA Pesticide National Synthesis Project Team where he helped develop the Watershed Regressions for Pesticide (WARP) model approach for estimating pesticide concentrations in streams. Before working for the NAWQA National Synthesis project, he was Chief of the NAWQA White River Basin Study for 10 years. He has served on the Indianapolis Department of Capital Asset Management Wet Weather Technical Advisory Committee, a work group organized by the International Life Sciences Institute for the U.S. Environmental Protection Agency (EPA) to provide input on strategies for determining pesticide exposure in drinking water, and an EPA lead interagency scientific working group charged with using National Water Quality Assessment Project pesticide data to help meet the goals of the Food Quality Protection Act. He is the author or co-author of over 60 articles and technical reports. He is also a co-author of the U.S. Geological Survey LOADEST program for estimating constituent loads in streams. Charles received the U.S. Department of the Interior (DOI) Superior Service Award in 1999 and the Department’s Meritorious Service Award in 2008. He was also a co-recipient of the USGS Eugene M. Shoemaker Communication Award in 2007. Charles has a B.A. degree in Biology from the University of Indianapolis and M.S. and Ph.D. degrees in Environmental Science from Indiana University.
