Waterloo Hydrogeologic

Waterloo Hydrogeologic is a company that specializes with groundwater modelling software, training, and consulting services. The company was started by Nilson Guiguer and Thomas Franz, who were developing software for their research at the University of Waterloo in 1988. The company was later founded in 1989 as Waterloo Hydrogeologic Software (WHS). The company first released FLOWPATH, which—at the time—was the first fully integrated graphical groundwater modelling software. In the fall of 1993, Waterloo Hydrogeologic became incorporated (changing their name to Waterloo Hydrogeologic Inc or WHI) and started with the development of Visual MODFLOW. The company diversified into groundwater software training and consulting services, as it expanded.
