Description: This introductory course provides participants with an overview of remediation technologies and best practices for removing contaminants from soil, groundwater, and surface water. The instructor will discuss site characterization requirements for effective remediation system design, as well as the best technologies available for effective remediation of various contaminants. Case studies will be reviewed and remediation successes and failures will be discussed.

About the Instructor: Heidi Blischke received her Masters in Geology and Environmental Engineering at Oregon State University. Ms. Blischke, RG, LHG, is Senior Hydrogeologist with Groundwater Solutions, Inc. She has more than 20 years experience conducting hydrogeologic site investigations, feasibility studies, remediation system design, remedy implementation, and system monitoring. She is a recognized expert in designing, conducting, and interpreting aquifer tests; collecting sediment, surface water, and groundwater data; interpreting water quality data; determining a chemical's fate and transport; understanding NAPL migration; developing conceptual site models; and implementing effective remediation approaches.

Case Studies

Review of Best Practices and Avoiding Common Mistakes

Class will begin each day at 8:30 A.M. and end at 5 P.M. Attendees will be given the opportunity to apply course concepts through numerous hands-on exercises.

After completing this course, participants will be able to:

- Understand the site characterization requirements for effective remediation system design,
- Describe some of the presumptive remedies for common environmental contaminants,
- List some of the effective remediation technologies for soil, groundwater, and surface water,
- Understand which remediation strategies are effective for a particular contaminant, and
- Develop a site assessment and remediation strategy that builds upon best practices.

Prerequisites: Basic understanding of contaminant chemistry and transport, hydrogeology, and site assessment is essential. Completion of NWETC's Contaminant Chemistry and Transport series (CHEM-403A & B) or similar course work is recommended.

Education Level: Introductory (some prerequisites required - see above.)

Course Materials: Each participant will receive a copy of the course proceedings including notes and reference material.

Continuing Education Units: 1.3

What to Bring: Mechanical pencil, scientific calculator, and a coffee mug and water bottle (to reduce waste). Please wear comfortable clothing appropriate for the prevailing weather.

Registration: $495 ($395 reduced tuition available for Native American tribes; government employees; nonprofits; students; and NAEP, NEBC, NWAEP members). You may register via the link below or by calling the Northwest Environmental Training Center at 206-762-1976.
