Environmental Engineering

Knowing What’s in the Ground.

The ground doesn't only bear loads — it holds a record of everything that's been spilled, buried, or drawn through it.

Environmental engineering is the work of understanding that record:
What's present, how it's moving, and what it takes to make a site safe to build on or hand over.

GES brings geotechnical and environmental expertise to the same projects, which matters more than it sounds: contamination, groundwater, and ground behaviour are rarely separate problems. From contaminated-site assessment to in-situ remediation and groundwater studies, we treat the subsurface as one connected system.

Environmental Services

  • Soil and groundwater remediation; excavation and removal monitoring.

  • Clay-liner and geomembrane systems for effluent and reservoirs; decommissioning and site reclamation; erosion and sediment control.

Environmental work is a regulatory and ethical discipline as much as a technical one — it has to satisfy authorities and stand up later. GES's principal chaired the Environment & Sustainability Committee of Engineers Canada's Qualifications Board and helped author its national guidelines on site remediation and climate-change adaptation.

That's the standard your file is held to.

Four-Step Environmental Process

Understand the Concern

Every environmental file starts with a reason: a development, a property transaction, a known spill, or a regulator's request. We define that reason first, so the investigation targets the right questions against the right standards.

Sample the Ground

We assess the site directly: soil and groundwater sampling, and the field work needed to find out what's actually present, and how far it has moved.

Assess & Plan

Laboratory analysis defines the nature and extent of any contamination. We turn that into a clear, regulator-ready path forward — management, monitoring, or active remediation.

Remediate & Close

We carry the plan through: remediation, confirmation sampling, and the documentation needed to close the file and satisfy the authorities.
