Open BC's well recordsThese are BC’s water records for South Pender Island parcel region. Our stored map has 349 land lots. One aquifer meets the lot rule below. Their whole-map totals include 242 well records. A record does not mean a well is still in use.
1 wells have BC water-chemistry records. 0 water-level wells help track change over time. These counts cover the selected aquifers in full. Counts alone do not show dirty water, a shortage or room for more homes.
These counts use the lots in our map’s region. That region may include nearby islands. The cutoff is 25 lots or 5% of the region’s land lots, whichever is larger. We round the 5% to a whole lot. At least that many land lots must link to an aquifer. Its totals then cover the whole aquifer, even outside this region. Read how we count.
Bedrock — Fractured sedimentary rock; 9.1 km²; mapped 2004. Linked to 348 regional land parcels.
Vulnerability Moderate; productivity Low; demand Moderate; quality concern Isolated.
242 wells on record; 1 artesian; 1 wells with BC water-chemistry records.
BC rates how easily dirt or waste from the surface could reach groundwater. Its ratings are Low, Moderate or High. High means the water has less natural cover to protect it. It does not mean the water is dirty now. Productivity means how readily water flows from the aquifer. Demand means how much it is used. These are BC's ratings.
Much of the islands' groundwater sits in cracks in rock. It does not move through all cracks at the same rate. These rock stores can hold little water and release it unevenly. Nearby wells can report very different flows. BC rates many of these aquifers Low productivity.
An aquifer is a layer of rock or soil that holds groundwater. We use BC’s maps and well records. A well linked to a regional lot and a well on a whole selected aquifer are different sets.
To pick an aquifer, we take 5% of the 349 land lots and round it to a whole lot. We use that number or 25, whichever is larger. The cutoff here is 25 lots. Its well total then covers the whole aquifer. Open the source for blank or changed fields.
Turn aquifer map edges on or off on the island map. These are broad records, not a test of any one well or lot. Open BC’s source to check a specific place.

Well counts do not show how much water is safe to use. A map gap does not mean there is no water.
