The Urban Geology of the National Capital Area Project was made possible thanks to the contribution of several people and organizations. The Informatics and Scientific Services Section, Terrain Sciences Division provided support in database compilation and management (R. Laframboise), GIS (A. Moore, M. Poirier, A. Prégent, L. Robertson), GeoServ development (M. Ballard, R. Laframboise), and Web enabling and designing (D. Lemieux). Thanks to the Ontario Geological Survey, in particular K. Baker, who provided a digital version of the original Subsurface Database, and for the digital version of the Paleozoic bedrock map (D.A. Williams). The Ministère de l'environment du Québec and the Ontario Ministry of the Environment and Energy are thanked for the Water Well Databases. Finally, thanks go to the critical reviewers (J. Aylsworth, M. Hinton and R. Klassen).
