Groundwater is a vital resource. It is one of the largest global sources of freshwater, and in Canada it is estimated that nearly 30% of the population relies on groundwater for their water supply (CCA 2009).
As groundwater is such a precious Canadian resource, the need to determine the vulnerability of a municipality’s groundwater supply to pollution is vital to sustaining its environmental health. That is why the Quebec Ministère de l’Environnement (Ministry of the Environment) recently founded an initiative to evaluate the risk of Quebec’s groundwater sources.
As part of this initiative the Quebec government created a fund to hire environmental consulting and hydrogeology firms to conduct groundwater vulnerability analysis using the DRASTIC index methodology (Aller & Al., 1987). One of the firms hired for this province wide undertaking was Richelieu Hydrogeologie Inc and Yves Leblanc, hydrogeologist and owner of the company.
In order to perform the analysis his firm was hired for Leblanc and his team require a mapping software that can both visualize all of the variables used to assess the vulnerability of groundwater resources and perform the necessary geostatistical functions.
