MORE INFORMATION NOW INCLUDED
 
I have now started to include more information in a blog type format on some of the individual web pages.  Eventually this might be put into a truer blog format, but right now it is just a series of short notes and or figures with short explanations.  More will be added as I find new examples. 

For IE users - If the News section below cannot be seen the same details are in the Courses/Training Section.

 GEOCHEMICAL MODELING SHORT COURSE May, 2019 -  next course April 2020. 

We had 16 attendees in the 2019 course. 

This course has been completed, I expect to put on a course on during the week of April 20 - 24, 2020,  in Lakewood, Colorado.  Contact me at jmahoney@mahoneygeochem.com for more information.   Look for announcements here after December 2019.  Or go to the PHREEQC User's Site at

Once again I will be putting on my five-day course on Geochemical Modeling sometime in April 2020.  The exact data has yet to be determined, but the week of April 20th through the 24th, 2020 is most likely.  The course will be held in Lakewood, Colorado.  This five day course will cover PHREEQC, PHAST, HYDRA/MEDUSA and possibly PhreePlot.   The course is a combination of lectures  and hands on exercises.   Contact John Mahoney at jmahoney@mahoneygeochem.com for more information.  

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