Ground‐water samples from a portion of a semi‐confined buried glacial channel aquifer in southeastern Saskatchewan, Canada, were collected and analyzed to determine the spatial and temporal variations of the major chemical constituents, pH, Eh and Fe. Dilute Ca‐HCO 3 type water characterized the shallow portion of the aquifer. There was a linear modified Piper Plot trend toward more concentrated Na‐SO 4 type water with increasing depth in the aquifer and with increased distance along the ground‐water flow path. Ground water flowing from a well penetrating the shallow portion of the aquifer responded chemically to an intense spring storm event. The ground‐water chemistry of a flowing well completed in the deep portion of the aquifer did not respond to this intense spring storm, but showed a temporal chemical trend which paralleled a midsummer recharge event. The spatial and temporal hydrogeochemical variations indicate that two chemically distinct ground‐water components, resulting from two different physico‐chemical ground‐water flow origins, are probably recharging and mixing within this portion of the buried channel aquifer.
