This page aggregates mirrored provincial aquifer and GWELLS records for South Pender Island parcel region. Of 349 regional land parcels, enough are linked to one aquifer to meet the coverage threshold. These aquifers carry 242 well records, 1 of them with provincial water-chemistry data.
Counts use stored parcel-region membership. They are not an island-only geographic wells census. Aquifer totals cover each selected aquifer in full, including any area outside the parcel region; selection requires at least 25 parcels or 5% of regional land parcels.
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 provincial water-chemistry data.
The Province classifies each mapped aquifer's intrinsic vulnerability — how easily contamination at the surface could reach the water — as Low, Moderate or High, based on factors like depth to water and what covers the aquifer. A High rating means relatively little natural protection between the surface and the water people draw from. It describes susceptibility, not current contamination. Productivity describes how readily the aquifer yields water; demand describes the level of use. These are the Province's classifications, not ours.
Most Gulf and Northern Gulf island aquifers are fractured rock: water sits in cracks in sedimentary or crystalline bedrock rather than in a porous bed of sand and gravel. Fractured-rock aquifers store comparatively little water and move it unevenly, which is why neighbouring wells on the same island can report very different yields, and why the Province rates most of these aquifers Low productivity.
Aquifer boundaries are a toggleable layer on the island map. This page presents provincial data with explanatory context; it makes no claims about individual wells or properties.
