Lisa Olsen is a Water-Quality Specialist working for the USGS Water Mission Area in Reston, Virginia. She has a BS in chemistry and an MS in environmental science from the University of Memphis. From 1993 through 2005, Lisa worked on studies of fate and transport of nutrients, pesticides, VOCs, and other contaminants in Tennessee and Maryland. In 2006, she took a technical advisory position in the California Water Science Center and later transitioned to the Southeast Region of the United States. During 2010 to 2013, she served on the USGS NAWQA National Target Analyte Strategy workgroup to prioritize constituents for monitoring in water and sediment. In 2018, she moved into the Laboratory & Analytical Services Division. Lisa credits her coauthors, James Gray and Jerry Casile, also in the Laboratory & Analytical Services Division, for some of the content in this presentation.
