WEB-PHREEQ: Aqueous Geochemical Modeling
WEB-PHREEQ is a web-based computer application for aqueous geochemical modeling. WEB-PHREEQ was developed for classroom teaching and for routine calculation of the distribution of chemical species in water. Users can calculate the effects of mixing of waters, adding phases to the solution, or changing the solution's temperature, Eh, or pH. The site features an easy to use interface, frequently asked questions and on-line instructions. This web-based application is a simplified version of a more complex stand alone program that is also linked from the site.
