Environmental Geophysics Applied to Site Characterization, Plume Mapping, and Remediation Monitoring
Citation:
Werkema, D. Environmental Geophysics Applied to Site Characterization, Plume Mapping, and Remediation Monitoring. webinar, webinar, Webinar, October 15, 2018.
Impact/Purpose:
Environmental Geophysics is used for many subsurface investigative objectives. This webinar gives a broad overview of geophysical techniques applied to environmental objectives. The presentation highlights recent research, case studies, and technical support. This webinar should impact the audience in the utility and application of geophysical methods for environmental field studies to improve site characterization, monitoring, and conceptual site model development.
Description:
Environmental geophysics investigates the geophysical response to natural and anthropogenic materials, processes, and alterations, which impact human health and ecosystems within the near surface of the earth. This presentation will cover biogeophysics, geophysical monitoring and characterization of contaminant plumes and remediation, groundwater – surface water interactions, using geophysics for conceptual site model (CSM) development, and online resources soon to be available at epa.gov. An overview of biogeophysics, which is the geophysical investigation of microbial processes and interactions in the earth, will include a brief summary of the geophysical response to biogeochemical reactions concluding with the current state of the science. Examples of using geophysical methods for monitoring remediation and contributing to the understanding of a site’s geology will be shared. Mapping and monitoring the interaction between groundwater and surface water are included with examples utilizing fiber optic distributed temperature sensors and electromagnetic induction. The presentation will conclude with a description of EPA’s Environmental Geophysics web presence that, once published, will include an online textbook, references, models, and decision support applications.
