I happen to live on top of a huge aquifers, and there are some artesian wells in the area. Not far south of us, you leave the Wascana Basin and are into a completely different geology. The water is deeper down, not as abundant, and often is sitting over a layer of oil even deeper down. The reason they don't mix is because the soil layer is over a mile deep before you hit bedrock, and is of heavy clay type. My brother in law lives about 20 miles north of here, his well is close to 400' deep, and his water quality is very iron heavy, to the point of being barely drinkable, and is very slow to revover if he pumps any volume. I witched his entire property for him (a weird talent that surprised me), and found the only source of water below him. A mere 1/4 mile from him one way is a series of artesian wells, and within an eighth of a mile the other way the groundwater is so shallow and plentiful that the local vegetable farmers irrigate with it rather than pump water from the Qu'Appelle river which runs through the valley they are in.
