The Northwest Environmental Training Center presents:
Contaminant Chemistry
and Transport in Soil and Groundwater
Course No. CHEM-403B
July 26 - 27, 2006, 8:30 A.M. to 5 P.M. (2 Days)
Eldorado
Reno Hotel Casino
345 N. Virginia Street, Reno, NV 89501
Instructor: Erick McWayne, Northwest Environmental Training Center
Description:
This course provides participants with an overview of key concepts essential
to understanding environmental contamination and provides a fundamental understanding
of the release and transport of chemicals in soil and groundwater. This material
is intended for environmental professionals who are not chemists, but who
require a fundamental understanding of contaminant behavior and monitoring
parameters for their work. This course is recommended for all environmental
professionals working with contaminated soil and water with minimal formal
training in this subject. The course material will greatly enhance on-the-job
training. It is also recommended for project managers seeking a review of
the subject.
About the Instructor:
Mr. McWayne has extensive experience with soil, groundwater, and geophysical
investigations for the characterization of contaminant transport and fate.
As an environmental consultant, Mr. McWayne served as a project manager for
remedial investigation and feasibility studies at numerous Department of Defense
and other client sites, conducted environmental compliance audits, and performed
pollution prevention audits and siting studies for electrical power plants.
He currently serves as Executive Director of the Northwest Environmental Training
Center and teaches workshops in transport and fate, environmental chemistry,
and hydrogeology in Alaska, California, Idaho, Montana, Oregon, and Washington.

This course is part of a series and is preceded by the Fundamental Contaminant Chemistry Workshop (CHEM-403A), July 25, 2006. Attendees may register for either course individually or both courses. A discount applies when registering for both courses. Courses will begin each day at 8:30 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 velocity - Demonstrate an improved overall understanding of environmental chemistry |
Prerequisites: Completion of CHEM-403A - Fundamental Contaminant Chemistry workshop, equivalent course work, or on the job experience.
