Project: Regional Groundwater Model for the Region of Halton 

Client: Regional Municipality of Halton 

Objectives:

• Develop an integrated groundwater/surface water model of the wellfields in the Region of Halton.
• Identify additional water-supply targets.
• Delineate capture zones.
• Evaluate the sensitivity of the wellfields to surface-water contamination.

Outcomes:

• A detailed understanding of the interaction between the rivers and the aquifer systems.
• A useful management tool that allows Halton staff to perform additional analyses and simulations.

Key Aspects:

• A well database that is full integrated with the hydrogeologic model simulations.

Project Description:

EarthFX developed, in collaboration Halton staff, a regional database of over 70,000 MOEE wells, regional pumping wells and associated geologic and monitoring data, stream-flow information and GIS coverages to support the development of a regional groundwater flow model. EarthFX staff then developed a five-layer hydrogeologic model to evaluate significant aquifers and simulate recharge, discharge, groundwater/surface water interaction and pumping activities.
