Oak Ridges Moraine (ORM) is located in the Greater Toronto area, in the south of Ontario. It extends eastward from the Niagara Escarpment and along the axis of the ORM located north of Ontario Lake. The ORM complex consists of a sequence of aquifers and aquitards. These consist of Halton Till and Newmarket Till. There are two main aquifers: Oak Ridges Moraine Sediment aquifer and Lower Deposits aquifer. These are separated by the aquitards however the leakge in the aquitards allow the connection between the aquifers. The dataset describes in details the surficial aquifer media and groundwater flow through the different hydrogeological unit. It also provides information on confinement, surficial sediment thickness, groundwater depth, surficial hydraulic conductivity, recharge and discharge, aquifer potential, groundwater usage and quality. The dataset is a summary of data and hydrogeological information for all aquifers, aquifer systems and hydrogeological contexts of the Oak Ridges Moraine project.
This map was created to provide a regional frame of the spatial distribution of the boreholes and water wells within the Oak Ridges Moraine.
