Aquifer Confinement Conditions, Groundwater Geoscience Program

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. Aquifer confinement is derived from geology, stratigraphy and hydrogeological unit thickness. The dataset represents the confinement assessment of the local area over the hydrogeological unit, from a controlled vocabulary.
