Résumé(disponible en anglais seulement)
Waterloo Region is one of the largest municipal users of groundwater in Canada. Approximately 80% of its water supply is derived from bedrock and overlying sand and gravel aquifers with 50% of that being derived from aquifers contained within the Waterloo moraine (Ministry of the Environment, 2009; Aquaresource Inc., 2009). A population of just over 500,000 people is supported by 39 well fields comprising 122 wells (Lake Erie Region Source Protection Committee, 2012). Industrial development within this area over the past 100 years has resulted in more than 800 industrial sites with potential contaminants (Sanderson et al., 1995; Hodgins et al., 2012). There are also concerns regarding aquifer contamination from modern land use, such as application of road salt and agricultural nutrients (Bester et al., 2006). Recommendations from the Walkerton enquiry (O¿Connor, 2002 ) stressed the importance of understanding the geologic controls on surface and groundwater flow and how they can be used to predict where significant recharge and discharge areas (source water) are located, as well as where aquifers are more susceptible to surface contamination.
Résumé(Résumé en langage clair et simple, non publié)
Les aquifères de la moraine de Waterloo sont l'une des sources d'approvisionnement en eau souterraine municipale les plus importantes au Canada. Les aquifères régionaux sont aussi parmi les plus étudiés et modélisés au Canada. Cet article contribue à l'amélioration de la compréhension de l'hydrostratigraphie régionale et du des caractéristiques des aquifères et des aquitards.
