What percentage of rural household water supplies in Alberta comes from groundwater sources?

The percentage of rural household water supplies in Alberta that comes from groundwater sources is notably high, primarily because groundwater serves as a reliable and accessible source of drinking water in many rural areas. Alberta has vast aquifers and groundwater is often the most economical option for rural households, offering consistent water supply for various uses, including domestic, agricultural, and livestock needs.

Groundwater is also typically less susceptible to surface contamination compared to surface water sources, making it a preferred choice in rural settings where infrastructure for surface water collection and treatment may not be present. This preference, combined with the geological features of the region, supports the assertion that up to 90% of rural households rely on groundwater sources for their water supply.

The values indicated in the other choices understate the reliance on groundwater in Alberta's rural areas and do not reflect the evidence showing such a high dependence on this resource. Groundwater plays a crucial role in ensuring the sustainability and safety of water supplies for rural communities in Alberta.
