Managing Contamination
with Clarity and Control

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.

Organic and Inorganic Contamination Management

GPT designs remediation strategies that are tailored to the specific contaminant type, ensuring effective, compliant, and long-term solutions.

Organic
Contamination

Organic contaminants are carbon-based compounds, often linked to hydrocarbons and industrial chemicals. These include fuels, oils, solvents, and pesticides; typically originating from spills, leaks, or industrial processes.

These contaminants adsorb to soil and dissolve in groundwater, sometimes breaking down naturally over time, but often requiring targeted remediation techniques that are fit for purpose based on the potential receptors they might impact nearby.

Inorganic Contamination

Inorganic contaminants include heavy metals, salts, acids and other mineral-based substances. These are often associated with input or byproducts associated with mining, industrial waste, and farming.

Unlike organic pollutants, inorganic contaminants are not always metabolised by naturally occurring bacteria and can persist in the environment, requiring specialised containment, stabilisation, or removal strategies.
