The province maps aquifers where wells and studies give enough to go on, mostly in settled valleys; most of BC isn't mapped, and a lot outside every outline can still have groundwater. Outlines are drawn from geology and well logs at the scale of the study, so an edge can be well off on the ground, and one aquifer can lie under another. Wells are linked to an aquifer by provincial staff from the driller's log: not every well inside an outline is linked, and well depths and yields are as the driller reported them, often from a short test.

These are mapped ratings and drillers' records, not a test of any one lot. Before you buy a property on a well, or plan to drill, ask a qualified hydrogeologist or a registered well driller what this aquifer gives where you are, and test the water.
