"Particularly serious is the potential for salt water intrusion along the settled coastal areas.
Heavy pumping can draw sea water into the aquifer, contaminating the fresh water."
Living on Hornby Island (brochure)
The Islands Trust Council has long been concerned about the issues of water quality and quantity on the islands of the Islands Trust Area. The Islands Trust does not have the jurisdiction to regulate water or wells. That is a provincial and regional district responsibility. Local trust committees can protect groundwater using land use planning tools. The Islands Trust also promotes sustainable water use and advocates on behalf of islanders for better provincial water legislation.
The Islands Trust Council's strategic plan for the 2014-2018 term of office includes the objective to protect the quality and quantity of water resources and specifically to advocate for and educate about water conservation measures (e.g. rainwater catchment, greywater recycling).
