Résumé(disponible en anglais seulement)
Groundwater geochemistry is increasingly being recognized as a valuable tool in regional characterization of aquifer systems. In support of such investigations, the OGS has developed and maintains the Ambient Groundwater Geochemistry (AGG) database, which characterizes groundwater across a wide spectrum of chemical and isotopic parameters at near-uniform regional sample coverage. The original stated objective of the program was to determine the chemical composition of groundwater in Ontario's major rock and overburden aquifers to understand the relationship between water chemistry and aquifer chemistry. However, it was recognized from the outset that the database would have additional uses, and this has proven to be the case many times over. Since 2007, data from the AGG program has formed the basis of 15 separate OGS-supported regional studies on groundwater mapping-related themes. Many of these have been graduate theses and most include regional characterization and mapping of phenomena such as: (1) shale gas occurrence, (2) breathing wells, (3) buried karst, (4) natural contaminants in groundwater (arsenic, fluoride, iodine, methane, hydrogen sulphide, etc.), (5) the chemical effects of buried valleys and marine sediments in eastern Ontario, and (6) tritium fallout patterns in southern Ontario. The regional effects of various anthropogenic influences on groundwater chemistry have also been noted including the chemical effects of overpumping of aquifers, legacy gas wells, road salt application, and septic and agricultural influences.
The data have been publically accessible since 2011 and we are aware that it has also been put to use in many independent studies by researchers in private industry, academia and government. As with other OGS products such as geological maps, the AGG database is available for use by any public stakeholder and is likely to remain a valuable public asset into the foreseeable future.
