NGWA Offers Short Course on Groundwater Geochemistry

Course will provide basics necessary for site assessment and remediation projects

The National Ground Water Assn. (NGWA) is offering the short course “Fundamentals of Groundwater Geochemistry” March 14 and 15 in San Jose, Calif.

An important step in completing a successful site assessment or remediation project is understanding the geochemical aspects of the work. This course is designed to provide a thorough understanding of the principles of geochemistry.

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

In this course, participants will learn about:

• Principles of groundwater geochemistry;
• Mineral equilibrium;
• Solution/gas interactions;
• Oxidation/reduction reactions and measurements;
• Redox processes and interpretation;
• Adsorption/desorption processes;
• Migration of organic and inorganic groundwater contaminants;
• Principles of remediation with application to inorganic contaminants;
• Remediation of organic contamination;
• Relationship of geochemical reactions to groundwater quality, aquifer material and associated contamination;
• Impacts of geochemical conditions on remediation efforts;
• How to create sampling and analysis plans; and
• Requirements for data collection and presentation methods.

This introductory-level course is best suited to geologists, engineers, project managers, regulators and environmental professionals involved in risk assessment and remediation.

The instructors are Bill Deutsch, a senior geochemist at Pacific Northwest National Laboratory operated by Battelle, and Patrick Longmire, Ph.D., a hydrogeochemist at Los Alamos National Laboratory.
