WSA Bangor A and B
Observation wells WSA Bangor A and B were constructed in 1970 to observe natural groundwater level fluctuations in what is believed to be a recharge area in the southeastern part of Saskatchewan. The wells also functioned as regional observation wells for the Yorkton aquifer system and control monitors for observations at Crater Lake. Bangor A was completed to a depth of 39.16 metres in fine-grained sands of the Empress Group. The Empress Group is overlain by till of the Sutherland Group, which in turn is overlain by an upper aquifer believed to be part of the Floral Formation, in which observation well Bangor B was completed to a depth of 15.18 metres.
The hydrographs for the two wells show similar patterns, with the levels slightly higher in Bangor A indicating a small gradient from the Empress Group into the upper aquifer. Both wells show very similar sharp water level increases of well over a metre in later 2010 carrying through the fall of 2011. Previously the largest annual fluctuation had been about half a metre. The spike in Bangor A is quite striking given its 39 metre depth. Water levels in both wells continued to record high levels in 2012 and 2013 with Bangor A and B reaching approximately 516.7 and 516.5 metres respectively.
The water chemistry of the two aquifers is different. The deeper water from Bangor A is of the calcium/sodium-sulphate/bicarbonate type with a sum of ions concentration of approximately 1940 mg/L while the upper aquifer water from Bangor B has been reported by the Saskatchewan Research Council to be of the calcium-bicarbonate type with a much lower sum of ions concentration. No water quality record was found for Bangor B.
