NGWA Offers 1, 2-Day Courses in November

The National Ground Water Association is offering three courses in early November.

They are:

  • A two-day course, “Advanced Techniques for Evaluating and Quantifying Natural Attenuation,” on Nov. 5-6 in Denver, Colo.
  • A one-day course as a general introduction to the field of petroleum hydrogeology on Nov. 4 in Costa Mesa, Calif., and
  • A one-day course on LNAPL volume, mobility and recoverability for recovery systems design on Nov. 4 in Costa Mesa.

Monitored natural attenuation (MNA) has become widely accepted as a remediation alternative for solute plumes in groundwater. The course provides the hands-on data analysis techniques required to effectively evaluate natural attenuation at sites with petroleum hydrocarbons, chlorinated solvents, and other contaminants in groundwater, and then effectively apply monitored natural attenuation as a remediation alternative.

This introductory- to intermediate-level course is best suited to hydrogeologists, scientists, project managers, and regulators.

Instructors are Michael J. Barden, president and principal geologist with Geoscience Resources Inc. in Albuquerque, N.M., and Todd H. Wiedemeier, PG, president of T.H. Wiedemeier & Associates LLC.

In the introduction to petroleum hydrogeology course, Scott Bair, Ph.D., a professor in the Department of Geological Sciences at Ohio State University and formerly of Stone and Webster Engineering, will teach geologists and engineers about the properties of petroleum; source rock characteristics and origins of kerogen, tar, petroleum, and gas; and physical and petrographic characteristics of reservoirs and caprocks, among other topics.

The LNAPL volume, mobility and recoverability course will show how diverse information such as soil core analysis, product bail-down tests, historical fluid levels, and recovery system performance can be integrated into an LNAPL Conceptual Site Model (LCSM) that is used to meet product objectives.

Instructors are Don Lundy, principal hydrogeologist, Environmental Systems & Technologies, a division of Groundwater & Environmental Services Inc., and Mary Ann Parcher, site operations manager and principal scientist for the company.

Participants will learn how to apply fundamental concepts of multiphase fluids in porous media as applied to LNAPLs, plan field and lab data collection at LNAPL sites, and interpret soil/rock core photo imagery and laboratory tests for fluid and matrix properties that control LNAPL distribution. They also will learn how to estimate LNAPL volume, mobility, and transmissivity across the plume area; integrate LNAPL and site hydrogeologic data into a workable LCSM; and examine case studies that illustrate development of an LCSM under different petroleum site conditions and geologic settings.

This intermediate- to advanced-level course is best suited to geologists and hydrogeologists; soil scientists; environmental scientists and engineers; chemical and geotechnical engineers; project managers, task managers, and technical managers; and environmental case workers with regulatory agencies. Although not required, background experience with LNAPL site investigations, remediation, and/or regulatory decisions is helpful.
