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 seeking 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.
Course Topics:

This course is part two of a three-part series. It is preceded by Fundamental Contaminant Chemistry (CHEM-403a) on October 4, 2010, and followed by Monitored Natural Attenuation (GHYD-410) from October 7 - 8, 2010. Attendees may register for these courses individually or as a package. A discount applies when registering for two or more courses. Courses will begin at 8AM and end at 5PM each day.

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.

Education Level: Introductory to intermediate/refresher.

Prerequisites: Completion of CHEM-403A - Fundamental Contaminant Chemistry workshop, equivalent course work, or on-the-job experience.

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

Continuing Education Units: 1.5 CEU's

Registration: Early Bird rate $545/$445 if registered by July 9; $595/$495* thereafter
(*reduced tuition is available to employees of Native American tribes, nonprofits, and government agencies; students; and NAEP members). An additional discount applies when registering for CHEM-403A and/or GHYD-410. You may register via the link below or by calling the Northwest Environmental Training Center at 206-762-1976.
