NGWA offers course on advanced techniques for evaluating and quantifying natural attenuation

0
The National Ground Water Association is offering a two-day course, “Advanced Techniques for Evaluating and Quantifying Natural Attenuation,” on November 5-6 in Denver, Colorado.

Monitored natural attenuation (MNA) has become widely accepted as a remediation alternative for solute plumes in groundwater. The use of MNA requires a sound understanding of natural attenuation mechanisms and their interaction with source and transport processes in order to evaluate the potential efficacy of MNA. Furthermore, a practitioner must be able to accurately quantify natural attenuation to make a solid case for MNA as a viable remedial alternative.

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.

Course instructors:
• Michael J. Barden is president and principal geologist with Geoscience Resources Inc. in Albuquerque, New Mexico, and provides consulting services in hydrogeologic evaluation, environmental biogeochemistry, modeling, and risk assessment.
• Todd H. Wiedemeier, PG, is the president of T.H. Wiedemeier & Associates LLC. Wiedemeier has more than 14 years of experience in remediation and has conducted natural attenuation and bioremediation feasibility studies at more than 100 sites contaminated with fuel hydrocarbons, MTBE, and chlorinated solvents.
