Class Details

Purpose
To present an overview of site characterization approaches to support evaluation of the potential for Monitored Natural Attenuation (MNA) as a remedy for inorganic contaminants in ground water. The workshop will include discussion of the types of processes that can lead to attenuation of inorganic contaminants within ground water, the types of site characterization data needed to identify process mechanisms, and the capacity to sustain attenuation under site-specific conditions.

Technical Issues to Be Discussed
Discussion topics include:

• Attenuation processes
• The types of field and laboratory data needed to support site evaluation
• A tiered process for structuring the site characterization effort
• The role of models to support site characterization

The group will also look at case studies where MNA was evaluated as part of the remedy selection process, and discuss in more detail individual contaminants of interest to the Region.

Attendance is open to EPA, State and Tribal regulatory personnel only. Attendees are responsible for their own travel.
