National Ground Water Association

September 6, 2012 • 2 p.m. ET (11 a.m. PT)

presented by Bill Deutsch

Webinar overview

During this one-hour Webinar, you will be introduced to groundwater geochemical modeling and the tools available to make the necessary calculations of water/rock/gas interactions, which, in turn, can be used to estimate natural attenuation of contaminants, design and implement applied remediation methods, and predict longevity of a treated system.

You will learn how:

• Geochemical modeling of an aquifer provides a method of simulating interactions between the water, solids, and gasses comprising the subsurface chemical system
• Data collected on groundwater composition can be used with a computer code such as PHREEQC or Geochemist’s Workbench® to identify reactive minerals in the aquifer and develop a conceptual geochemical model that corresponds to the natural or impacted environment.

Examples applicable to typical groundwater characterization and remediation projects will also be discussed.

Who should attend?

This Webinar is designed for any groundwater professional interested in understanding the geochemical processes that affect the composition of water as it moves through the soil zone and the underlying aquifer.

It is also designed for project managers/designers who are considering in situ chemical treatment of an aquifer who need a method for understanding the system they will be treating so that accurate dosages are calculated and surprises avoided.

Education level

Introductory; university-level chemistry is desirable.
