* More about groundwater extraction in the South Wellington to Nanoose water region:
According to the MOE Wells Database (BCGOV ENV Water Protection and Sustainability Branch, 2012) WR5-SW-N has the second highest number of water wells (1685 wells) of the six water regions in the RDN.
The MOE database likely only represents a fraction of the actual wells currently in use. Many well records may not have been entered into the database and some wells may simply not be in use or have been abandoned. As there is no mandatory requirement for submitting well logs or well abandonment records, it is not possible to determine the groundwater demand from private wells with any degree of certainty, nor is it possible to assess the vulnerability that may exist with improperly abandoned or standing water wells.
