Found 10 records similar to Aquifer Vulnerability Index

Federal

A measure of the intrinsic susceptibility of an aquifer representing the tendency or likelihood for contaminants to reach a specified position in the groundwater system after introduction at some location above the uppermost aquifer. The method used to create the dataset is described in the metadata associated with the dataset. The dataset is a general assessment of the vulnerability of the hydrogeological unit considered as a whole. It features the local and regional qualifiers in a controlled vocabulary list referring to the extent where the vulnerability value is valid.

The dataset was developed as part of the Risk Assessment Framework for Coastal Bedrock Aquifers project completed by Simon Fraser University, for the Ministry of Environment and the Ministry of Forests, Lands and Natural Resource Operations. Features in the dataset show the vulnerability of coastal aquifers on Salt Spring Island to salt water intrusion, based on their intrinsic susceptibility (aquifer properties such as distance from the coast and topography), groundwater pumping (well density and type of use) and coastal hazard (coastal morphology and vulnerability to flooding from storm surges). This link refers to the Master of Science Thesis Report prepared by Jeanette Klassen in 2015 as a component of the collaborative study between Simon Fraser University and the Province of British Columbia.

The dataset was developed as part of the Risk Assessment Framework for Coastal Bedrock Aquifers project completed by Simon Fraser University, for the BC Ministry of Environment and the BC Ministry of Forests, Lands and Natural Resource Operations. Features in the dataset show the vulnerability of coastal aquifers on the Gulf Islands to salt water intrusion, based on their intrinsic susceptibility (aquifer properties such as distance from the coast and topography) and groundwater pumping (well density and type of use).

The confinement describes the types of aquifer: confined, unconfined and semi-confined. Confined aquifer is bounded from above and below by impervious formations. Unconfined aquifer has a water table which serves as its upper boundary. Semi-confined aquifer is in between.

Polygon features represent developed ground water aquifers in BC (that have been mapped). Most aquifer boundaries are delineated based on geology, hydrology and topographic information. Some aquifer boundaries stop at the border of BC mapsheet boundaries due to resource or data constraints at the time of mapping.

Sand bodies within the Sunchild aquifer subcrop over most of its extent, and because overlying Neogene sediment is relatively thin in the western part of the Paskapoo Formation, the unit expresses itself as the present-day topography. Constructing the Sunchild aquifer-thickness map was somewhat problematic because of the difficulty of mapping the step-like distribution and connection of sand bodies that, in places, are laterally adjacent to muddy intervals. The resultant isopach was generated by subtracting the Lacombe Member surface from the Sunchild surface to yield an approximation of Sunchild aquifer thickness. The Sunchild aquifer thickens from less than 50 m in the east to more than 300 m to the west.
