Understanding the risks associated with contamination is essential to making the right decisions. Our experts evaluate potential impacts on human health and ecosystems to guide the most effective, safe, and regulatory-compliant management strategies.

For example, when a contaminated site is intended for redevelopment, we assess the risks associated with the presence of contaminants in soils, groundwater, or ambient air. This analysis helps identify risk management solutions that protect health and the environment while reducing project costs and timelines.

In an industrial or mining context, we can determine whether current or anticipated emissions pose a risk to neighbouring populations and recommend the most appropriate measures. This approach lets you focus investments where they generate the most value while effectively supporting interactions with regulatory authorities and concerned communities.

Air emissions can raise regulatory and social acceptability issues. Our dispersion studies help anticipate air concentrations for regulatory purposes or to assess potential health and environmental risks.

Whether it involves adding, modifying, or optimizing emission sources at industrial facilities or treatment processes on a contaminated site, we produce analyses that go well beyond regulatory compliance.

We interpret results in their real-world context to support project development, minimize risks, and foster social acceptability.

With our unique combination of expertise in modelling, toxicology, and risk assessment, we turn complex data into concrete and strategic recommendations.

Groundwater is often invisible, but its influence on the environmental management of contamination can be considerable. Understanding its behaviour and that of the contaminants found within it makes it possible to anticipate risks, protect water resources, and optimize remediation strategies.

Our specialists understand and can model water and contaminant transport. In collaboration with our toxicology and risk assessment experts, they can provide a clear view of short- and long-term issues.

For example, on an industrial site contaminated with chlorinated solvents and located near inhabited areas, vapour intrusion can pose health risks.

Our specialists can predict the evolution of a contamination plume using hydrogeological models and can identify the most effective interventions to protect communities and the environment.

This in-depth understanding facilitates investment planning, reduces uncertainty, and supports regulatory compliance.

Every contaminated site presents its own reality. When contamination is complex and technical or regulatory constraints multiply, a standard approach is no longer enough.

SANEXEN designs integrated remediation strategies that account for environmental risks, development goals, operational constraints, and regulatory obligations.

For example, when redeveloping a former contaminated industrial site, complete excavation is not always the best option, and treatment processes do not always achieve regulatory objectives. By combining risk assessment and management, targeted interventions, technical impracticability, and environmental monitoring measures, it is often possible to protect human health and the environment while significantly reducing the scale of work, project costs, and timelines.

When environmental issues are complex or likely to have significant financial, regulatory, or legal repercussions, decisions must be based on solid facts.

Whether it involves identifying the source of contamination, understanding the biogeochemical processes at play, developing a regulatory strategy, supporting a litigation case, or providing expert testimony, our team puts scientific rigour in service of decision-making.

For example, in a case involving multiple historical owners, we can reconstruct the probable source of contaminants and document their evolution over time to clarify responsibilities and support regulatory or legal proceedings.

Our experts' analysis helps clients defend their positions with credibility and confidence.
