Groundwater (or ground water) is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The groundwater in this area is under stress both for quantity and quality.

The area has highly complex geology, formed by tectonic forces, glaciations, sea level fluctuations etc. The resulting inconsistent land types cause considerable variation in groundwater levels and availability.

Groundwater is mostly non-renewable, study finds Less than 6% of groundwater is replenished within 50 years. In this area the amount of precipitation that actually infiltrated into the groundwater each year is estimated at between 10 -18 cms near the coast to 18 - 25+ at higher elevations.

Understanding and Protecting the Well and Source.
Groundwater and well-head protection are essential components to providing healthy drinking water. Water can move through the ground at a few meters a year or many meters an hour.
Even if the well is tens or more than a hundred meters deep, contaminated surface water could reach the bottom of the well within a very short time during a heavy rain event.

Vancouver Island Water Resource Vulnerability Mapping Project.
This in depth, well researched report provide a technical explanation on the likelihood of groundwater becoming contaminated. https://web.viu.ca/groundwater/web.mala.bc.ca_files/News/Apr2010.htm Most of this area's geology is described as sand and gravel mixes at lower elevations. Sedimentary rock transitions to volcanic rock at higher levels. The amount of precipitation that actually infiltrated into ground is estimated at between 10 -18 cms near the coast to 18 - 25+ at higher elevations. |
