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. Jeramy R. Jasmann is an environmental geochemist whose research focuses on analytical chemistry and modeling tools for assessing water quality, water uses, and water suitability for human and ecological needs through investigation of stressors, stressor sources, controlling processes of fate and transport, along with real and perceived exposure effects. Jasmann earned his B.S. in Biochemistry from University of California Davis in 1997 and taught high school Chemistry, Earth Science, Biology, and Environmental Science for 12 years before returning to university. He earned his Ph.D. in Environmental Analytical Chemistry from Colorado State University, Fort Collins with an emphasis on novel treatment technologies and transformation mechanisms of recalcitrant organic pollutants, primarily 1,4-dioxane and chlorinated solvents.
Jasmann joined the U.S. Geological Survey in 2016 and is a Research Scientist in the Water Resource Mission Area's Laboratory Analytical Services Division, Strategic Laboratory Sciences Branch. Jasmann is the lab manager for the Integrated Water Chemistry Assessment Laboratory (IWCAL) in Boulder, CO and specializes in GC/MS/MS analysis of trace-levels bioactive organic chemicals in the aqueous environment and biomarkers of aquatic stressor sources. A full suite of organic and inorganic water quality constituents including trace metals and rare earth elements are collected for interpretive science studies and for validating hydrologic models for predicting environmental concentrations of contaminants in wastewater-impacted watersheds. His research is interdisciplinary and holistic in its approach, integrating hydrologic, chemical, and biological analyses, field work, on-site mobile fish exposure laboratories, and web-accessible, map-based modeling applications to synthesize and interpret the complicated hydrologic and ecological interactions within complex aqueous mixtures. Current research is on developing GC-MS/MS methods for screening multiple chemical classes of high priority aqueous contaminants with toxicological or regulatory implications, including pesticides, pharmaceuticals, consumer product chemicals, endocrine disruptors, fuel-based hydrocarbons and combustion products, surfactants and ubiquitous industrial chemicals (like PFAS and 1,4-dioxane), along with other livestock or urban runoff chemicals of interest.

Integrated Assessments of Potential Risks to Aquatic Organisms and Public Water Supply from Wastewater-Derived Chemical Mixtures in the Chesapeake Bay Watershed
Proper management of contaminants of emerging concern in the Chesapeake Bay region requires scientific efforts to understand the risk posed to aquatic resources from the “cocktail” of multiple contaminants that is often present. This research aims to assess the occurrence, sources, environmental impacts, biological effects, and the human health impacts of toxic contaminants in rivers. - Data

The data presented in this data release includes 11 field/water quality parameters, concentrations of 16 nutrients/anions, dissolved organic carbon, 14 organic contaminants, net estrogenicity concentrations, and 51 inorganic constituents in surface water collected twice from 28 stream sites and collected once from 2 stream sites in the Shenandoah Valley (Virginia and West Virginia, USA), in the suPotomac River Watershed Accumulated Wastewater Ratios and Predicted Environmental Concentrations
Treated effluent from wastewater treatment plants (WWTPs) contains contaminants not fully removed during the treatment process and that may pose environmental health risks when discharged to surface waters.

Temporal variability and sources of PFAS in the Rio Grande, New Mexico through an arid urban area using multiple tracers and high-frequency sampling
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous in the environment but sources are not well defined for temporal and spatial aspects within an urban environment, and especially for an arid urban environment subject to seasonal short term high-intensity precipitation events. A focused diel sampling was conducted in the summer of 2021 to assess the temporal and spatial variability of PFASAuthorsKimberly R. Beisner, Rebecca E.

Per- and polyfluoroalkyl substances (PFAS) have been detected in public and private drinking-water wells, springs, and surface waters in New Mexico; however, the presence and distribution of PFAS in water resources across the State are not well characterized.
