This webinar will present a general overview of several geophysical methods which are commonly used at environmental waste sites. The primary focus will be keyed to practical applications of each method. Geophysical tools will be presented in a manner so that the participant will be able to identify each tool by its physical appearance, what properties are measured, how information is collected and processed, method detection limits, how to select most effective method, methods that complement each other, and situations where some methods will not work. Also presented are details on how to plan or manage a geophysical survey which include gathering information to properly customize a survey to detect alleged targets. A brief introduction will also be given for a few basic borehole geophysical tools specifically for shallow two-inch diameter monitoring wells to optimize information gathering during well construction and for long term monitoring. Examples of surface and borehole information will conclude the webinar.

Jim Ursic, EPA Region 5, Field Services Division ( or 312-353-1526)
Jim is a Geologist who began his career working for ten years as a Borehole Logging Supervisor and Mine Geologist at multiple underground mines in New Mexico. During the last 33 years he has worked his way up the ladder, so to speak, to the Environmental Protection Agency where he has concentrated his time using direct-push methods for sampling soil, water, and soil gas, as well as conducting and overseeing near surface environmental geophysical surveys.

His time at EPA has been spent entirely within the Region 5 Superfund Program, in the Field Services Section, working in conjunction with Remedial Project Managers, On-Scene Coordinators and Brownfield Project Managers. During these years at EPA Jim has acquired and maintained multiple surface and borehole geophysical tools for the Region. Jim has also designed and constructed two environmental geophysical training sites for EPA's Environmental Response Training Program. The most recent constructed at The Ohio State University's Waterman Farm Facility for the purpose of training Federal and State personnel in various environmental geophysical methods.
