INTRODUCTION TO GEOCHEMICAL MODELING TOOLS:

Geochemical Modeling Courses

Presented by Mahoney Geochemical Consulting LLC

Since 2010, Mahoney Geochemical Consulting has prepared and presented numerous courses in geochemical modeling throughout the USA, Canada, South Africa, Australia and Sweden.  We can present customized courses for specific applications.  We generally cover PHREEQC, HYDRA/MEDUSA and PHAST as the primary modeling tools.  We also can present an advanced course which expands the PHAST modeling and includes a significant section that covers PhreePlot.

Since 2010, I have presented 19 courses (open and private) with more than 175 different participants attend these courses, the total number of participants is closer to 185, as some have returned to participate in my advanced courses.  

Partial Capture of Uranium Plume Prepared Using PHAST


Our next course in North America will be in April, 2020 in Lakewood, Colorado.   We have completed the May 2019 course; we had 16 attendees from the US, Canada, Chile, Brazil and Australia.  

This five day course will include:

  • Numerous hands on exercises drawn from the instructor’s experience, which are designed to provide “outside the box” thinking in the real world application of geochemical models.  
  • An alternative visual and intuitive approach to geochemical modeling using the HYDRA/MEDUSA package, and
  • The PHAST for Windows  program, which couples PHREEQC with a 3-D groundwater flow model, allowing for the construction of solute transport models that include pertinent geochemical reactions.
  • Some discussion and of time and interest allow some simple applications of PhreePlot

By the end of the course, participants will understand geochemical modeling, including its shortcomings, and be able to apply geochemical models to numerous environmental issues.  

We continue to update and expand the presentations in these courses.  These courses will include some additional discussion about the program PhreePlot and its ability to fit model parameters to observational data.  

PLEASE CONTACT jmahoney@mahoneygeochem.com for more details. 


 

POSSIBLE ADVANCED COURSE - Contact Me


In the past I have presented a more advanced course that includes more time with PHAST, and over a full day with PHREEPLOT.  To still fit this into a five day session this course skips some of the introductory material in the basic course.  We also do not cover Uranium Chemistry, Arsenic Chemistry or mining related topics.    We also use the plotting capabilities in PhreePlot to prepare various diagrams, such as Eh-pH diagrams, and cover HYDRA/MEDUSA only briefly. 

At this time this course is not scheduled.  Please contact me if you are interested in this course and if I get enough interest I will try and put this course on again.  

In my opinion PhreePlot will eventually become the primary method to optimize PHREEQC based models. It can be used in research applications, but as a consultant I find it helpful in a lot of situations.
