Understanding What’s Happening Below the Surface

Contaminated land presents both environmental and operational risks. Whether caused by industrial activity, oil spills, or historical land use, soil and groundwater contamination must be properly understood and managed.

We provide end-to-end contaminated soil remediation as well as soil and groundwater remediation services; from contaminated site assessments and risk assessment to remediation design, remedial action plans, and project execution.

Assessing Organic and Inorganic Groundwater Contamination

Our hydrogeological investigations are designed to accurately characterise both organic and inorganic contaminants; ensuring informed, defensible decisions.

Organic Contaminants in Groundwater

Organic groundwater contamination typically originates from human activity, including hydrocarbons and solvents.

These contaminants often form plumes that migrate with groundwater flow and may degrade over time, depending on environmental conditions.

Inorganic Contaminants in Groundwater

Inorganic contaminants include dissolved metals, salts, and nutrients, which may originate from industrial activities such as mining. These substances tend to persist in groundwater systems and require detailed modelling to understand their movement and long-term impact.
