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 across the country.
