Contaminated Sites Management

We support public and private sector clients in addressing environmental stewardship, governance, and societal needs. We work with our clients to address contaminant liabilities and develop technical solutions which are protective of human health and the environment.  We specialize in not only soil, sediment and water impacts, but also in how contaminants can create indoor air quality concerns. Dillon’s team of professionals include engineers, scientists, technologists, risk assessment specialists, and regulatory experts.

We have a long history of effective collaboration with regulators across Canada, at both federal and provincial levels, and understand what it takes to successfully govern our clients’ environmental affairs when it comes to contaminated sites management. These positive and long-standing relationships are especially important when our clients are required to report to shareholders and stakeholders on their liability obligations.

We understand the pressures industry, government and regulators face when community concerns are raised and need to be addressed when managing contaminated sites. The key is to strike the right balance amongst all parties such that human health and the environment can be protected through the implementation of tailored and practical solutions.
