Ronald W Harvey
Ronald W Harvey is a Scientist Emeritus Research Hydrologist for the USGS Water Resources Mission Area.
Ronald Harvey earned his PhD in Environmental Sciences from Stanford in 1981. Following an NRC postdoctoral fellowship, he conducted research for USGS National Research Program in Menlo Park, CA (1982-1990) and in Boulder, CO (1991-present). From 2002 to 2005 he served as the first president of the International Society for Subsurface Microbiology (ISSM). He is a former chair of the Environmental (Q) Division of the American Society for Microbiology and is an adjunct professor in Environmental Engineering at the Univ. Colorado. His research focuses on subsurface microbial transport and ecology. He has authored/co-authored over 100 papers in his field. Field studies involve microbial transport and ecology of granular, fractured-rock, and karst-limestone aquifers throughout the country.

- USGS: Technical advice/assistance regarding groundwater contamination problems for researchers in 30 different USGS Water Science Centers (WSC). Asked by WSC Directors/Associates & USGS program managers (e.g., Offices of Groundwater, Water Quality, Toxics) to provide technical input on microbiological issues.
- USDOE: Advice provided to Subsurface Science Program (SSP) over eight years facilitated an emphasis on subsurface microbial transport patterned, in part, after my earlier USGS Cape Cod site research. Chaired DOE’s formal peer review of SSP transport study.

Importance of Lake Sediments in Removal of Cyanobacteria, Viruses, and Dissolved Organic Carbon
U.S. Geological Survey (USGS) scientists determined that the colmation layer (top 25 centimeters of lake sediments) was highly effective in removing cyanobacteria, viruses, and dissolved organic carbon during water passage through the lake bottom to aquifer sediments.
