For Borehole ID 10141445, fresh water was probably derived from the nearby Twelve Mile Lake. The maximum depth of the lake is 28m whereas the borehole depth to water is 42.37m (Hevesi, 2019). The lithology is primarily made of gneiss. Gneiss can be sufficiently well broken up to induce fracture related porosity which explains why water was found so deep (Earle, 2006). For Borehole ID 10503151, there is no nearby waterbody to suggest any flow of water to the well. This might indicate that the freshwater was possibly derived from rainfall. The lithology where freshwater was found was that of clay and sand. Clay has a high porosity and limestone is known to absorb water well. For borehole ID 10441385, it is possible that the freshwater has seeped from the nearby Mitchell Lake. Most of the lake is relatively shallow, sitting at around 3m maximum depth (ecottagefilms, 2019). This could explain why this borehole has the lowest depth of water value. Water is not found at the same depth because the depth of nearby sources vary as seen in the case for borehole ID 10441385 and 10141445. It is also the case that different rocks have different porosity which affects where water settles underground. References: Hevesi, M. (2019).
