We assess and manage liabilities during investigation and remediation of contaminated soil, vapor and groundwater at multiple sites worldwide helping our client understand the environmental, human health and business risk. Our experts are experienced with managing incidents associated with a wide range of contamination compounds and hazardous waste, including PFAS, 1,4 dioxane, chlorinated solvents, metals, petroleum, pesticides and herbicides.

We design contaminated site remediation programs that couple a best-business approach to mitigate risks and ensure the site meets regulatory standards and is a safe place for employees, the public and the environment. Our expert team uses the latest innovative remediation technology with teams and consisting of multiple scientific disciplines - engineers, hydrogeologists, geologists, geochemists, economists, environmental scientists, hazmat specialists and toxicologists.

Our environmental expert teams bring local knowledge and a local trusted relationship with regulatory authorities and the public in the countries in which we operate. Our local presence is crucial as we use those local regulatory relationships, understanding of local and innovative data collection and remediation techniques to address contaminated sites quickly using local knowledge and the best team of global experts appropriate for the project.

The variety of contaminants differ from location to location and can be a complex mixture of contaminants, depending on the historical activities on the areas, thus the importance of our local presence and context. Gas stations, chemical factories, and various types of industry - the risks of contaminants, fate and transport, potential migration and potential exposure pathways vary. We see an increasing need for handling groundwater contamination, which has a significant complexity, i.e., where different groups of substances are mixed. Complex groundwater contamination may have a mixture of, e.g. , hydrocarbons, per- and polyflouroalkyl substances, phenols, PFAS, chlorinated hydrocarbons, volatile organic compounds, pesticides, or heavy metals. Some innovative tools we use include the new technology with ReMuve for contaminated groundwater.
