Jeramy R Jasmann, Ph.D.

Dr. Jasmann’s research efforts are focused on developing water quality evaluation tools, deepening our process understanding of aqueous constituents fate and transport, and providing integrative hydrological, chemical, and ecological assessment of water availability and suitability conditions in watersheds across the U.S.


Dr. Jasmann is a Research Chemist within the USGS ESPD Hydro-Ecological Interactions Branch in Boulder, CO. He earned his B.S. in Biochemistry from University of California Davis and his Ph.D. in Environmental Analytical Chemistry from Colorado State University in Fort Collins with an emphasis on novel treatment technologies and transformation mechanisms of recalcitrant organic pollutants, primarily 1,4-dioxane, chlorinated solvents, and lamotrigine. He currently specializes in GC/MS/MS analysis of bioactive organic chemicals and other relevant water quality constituents and tracer molecules in wastewater- or disaster-impacted groundwater and surface water. A large suite of organic and inorganic water quality constituents are collected for interpretive science studies performed by the lab: pharmaceuticals, personal care products, organic surfactants (alkylphenols, PFAS), wastewater indicators, endocrine disrupting compounds, trace elements and major ions.  

Special focus is given to interdisciplinary research to better understand the chemical fate and transport, exposure pathways, and toxicological effects that anthropogenic chemicals have on aquatic organisms and drinking water sources using fish exposure experiments in mobile laboratories. A GC/MS/MS wildfire fire biomarker method was recently developed for smoke aerosols deposited in snow and ice samples to improve the understanding of relationships between humans, wildfire frequency, and climate change. This fire tracer method is now being developed to analyze water and dry aerosol samples to use as an early warning signal to drinking water facilities and to help with source appropriation of hazardous pollutants impacting air and water quality that come from biomass vs. fossil fuel based combustion.
