Sediment-aquifer play types in a list of 30 key Canadian aquifers

There is a need for a classification scheme that can be applied nationally to aquifers in Canada. One approach is to adapt the "play" concept, which is used extensively in the petroleum industry. Adapted to groundwater aquifer classification the play concept can be defined on the basis of
aquifer geology, confining units (hydrostratigraphy) and hydrology (recharge - discharge). Identification and conceptualization of these characteristics requires knowledge of the geological evolution of the basin best achieved by basin analysis techniques. A synthesis of aquifer play types has the
potential to capture key messages embodied in the existing large set of data that comprises local case studies.
