Description: This course provides participants with an overview of key concepts essential for understanding soil and groundwater contamination and the selection of appropriate remediation approaches. This material is intended for environmental professionals who require a solid understanding of contaminant behavior, monitoring parameters, and how both relate to site remediation. This course is recommended for all environmental professionals working with contaminated soil and groundwater seeking a thorough review of essential topics. The course material will greatly enhance on-the-job training and is also recommended for project managers seeking a more thorough understanding of contaminant behavior.

This course is part of a series and is preceded by the Fundamental Contaminant Chemistry Workshop August 3, 2009 and Monitored Natural Attenuation August 6-7, 2009. Attendees may register for either course individually or both courses. A discount applies when registering for both courses. Courses will begin each day at 8:00 A.M. and end at 5 P.M. Attendees will be given the opportunity to apply the course material during hands on exercises offered throughout the course.

After completing this course, participants will be able to:

- Understand basic soil and groundwater chemistry;
- Calculate chemical partitioning;
- Understand the significance of temperature, redox potential, pH, DO, and other monitoring parameters;
- Apply soil chemistry principles to soil investigations;
- Apply water chemistry principles to groundwater investigations;
- Understand the chemical and biological aspects of natural attenuation;
- Estimate partitioning coefficients and calculate solute average linear velocities;
- Demonstrate an improved overall understanding of contaminant chemistry; and
- Use site-specific chemistry data for selecting appropriate remediation strategies.

About the Instructor: Mr. McWayne has fifteen years experience with soil, groundwater, and geophysical investigations for the characterization of contaminant transport and fate; and teaching contaminant chemistry, transport, natural attenuation, and hydrogeology. As an environmental consultant, Mr. McWayne served as a project manager for remedial investigation and feasibility studies at numerous Department of Defense and other contaminated sites. He currently serves as Executive Director of the Northwest Environmental Training Center and teaches workshops in transport and fate, environmental chemistry, and hydrogeology across the country.
