Fundamentals of Groundwater Geochemistry (short course #235)

Date: June 6-7, 2019
Location: Westerville, Ohio
CEUs: 1.6
Education level: Introductory to intermediate



This course is designed to provide you with a thorough understanding of the principles of geochemistry, as understanding the geochemical aspects is an important step in completing a successful site assessment or remediation project.

While many people have a solid understanding of hydrological processes, the chemical aspects of the site that largely impact contaminant fate and transport, and determine the outcome of the remediation effort, are not as commonly understood or appreciated.

Basic chemical interactions occurring between water and soil/aquifer material that determine the composition of natural water and affect the migration of contaminants will be covered in this course, as will the anticipated efficiency of remediation practices. Data collection, presentation, and interpretation of results will also be discussed.

Once this fundamental knowledge is obtained, it will be possible to integrate it into particular contamination situations and evaluate remediation systems given the site-specific geochemical parameters.
