The presence of contamination can limit the uses of real property, reduce property value, and attract regulatory oversight. The first step that we take for each contamination investigation and cleanup project is to understand our client’s goals. Then, we develop a plan for addressing the contamination in a manner and on a schedule that meets the client goals and maximizes value.


Cascadia’s Principals have managed numerous human and ecological risk assessments at industrial sites. Risk-based decision making is used to focus data collection and corrective action (e.g., industrial/engineering controls, vapor intrusion mitigation, hot spot treatement/removal, source control). Our approach to contamination issues gives stakeholders a meaningful opportunity to learn about and provide input on remedy decisions.
