Groundwater/Surface Water Interactions

Groundwater/Surface Water Interactions: Field and Mathematical Approaches (#242)

Date: December 6-7, 2018

Instructors:  Jeffrey A. Johnson, Ph.D., CPG, LRS, Meng Ling, Ph.D., PE​, Donald Rosenberry, Ph.D., and Kevin Russell​ 

CEUs: 1.4


​Learn about the tools and techniques used to characterize groundwater/surface water interactions, an increasingly timely topic as interest in this topic grows, during this two-day NGWA short course.

You will learn about the tools and techniques used to characterize these interactions to be able to evaluate the environmental risk they pose at contaminated waterways. You will also gain insight on the evolving regulatory perspectives relative to resource management, environmental investigations, and remedial actions.

The first day of the course will present field methods. Field work will be conducted to measure the physical and chemical conditions in the hyporheic zone. The projected methods emphasized will include piezometers, permeameters, and seepage meters.

Day two of the course will present mathematical approaches utilized to define the conditions at the interface, including a description of commonly used analytical and numerical approaches to assess groundwater flux and attenuation in the hyporheic zone. These approaches will be presented relative to existing regulatory science.

Introduction to Groundwater Geochemistry Reaction Modeling

Introduction to Groundwater Geochemistry Reaction Modeling (#292)


Date: December 6-7, 2018

Instructor: Bill Deutsch 

CEUs: 1.5

Course overview

This two-day short course will provide you an introduction to the important geochemical processes that affect groundwater composition and methods for developing reasonable conceptual models using site-specific data. Conceptual models will also be combined with an equilibrium modeling code to produce a geochemical model of a site.

The geochemical processes that affect rviewthe composition of natural groundwater and the movement of groundwater contaminants include a wide variety of solid phase/water and gas interactions in the subsurface. It is oftentimes impossible to predict the impact of these interactions on groundwater composition without a realistic conceptual geochemical model of the system and a means to calculate the interdependent chemical reactions.

This course will strengthen your understanding of the fate and transport of groundwater contaminants, and provide you with techniques and software for using site data to develop geochemical models for a given site. In addition to site understanding, geochemical models can be used in a predictive mode for evaluating natural attenuation of contaminants and designing in situ and ex situ remediation methods.

You will receive an introduction to groundwater geochemistry and chemical reaction modeling using PHREEQCI (free, widely used USGS code) for natural and contaminated systems. Emphasis will be placed on inorganic reaction modeling involving major ions and trace metals. Each session will include a discussion of an important geochemical process (such as mineral dissolution/precipitation, oxidation/reduction, or adsorption/desorption) and a demonstration of modeling the process with PHREEQCI. Practice sessions will integrate examples presented in lectures into realistic problems to provide valuable experience in modeling at specific sites.

Groundwater Economics

Groundwater Economics: Project Cost-Benefit Evaluation (#214)


Date: December 7, 2018

Instructors:  Chuck Job

Course overview

This course will provide you with a review of basic economic concepts, and discuss factors significant in cost-benefit/life-cycle evaluation and discounted cash flow analysis. Solutions to diff​erent key economic evaluation steps will be developed.

You will also have the opportunity to discuss economic evaluation issues you’re facing.

The course will undertake a guided groundwater problem, prepare a collaborative cost-benefit/life-cycle evaluation, and discuss results and alternative outcomes.

Learning objectives​

Upon completion of this course, you will be better able to:

  • Specify costs and benefits in a life-cycle approach
  • Understand discounted cash flow​
  • Apply cost-benefit concepts to a collaborative project evaluation.
