Risk Assessment

Risk assessments are vital in the process of evaluating and restoring contaminated sites, from determining human health and ecological risks to establishing property use limitations for expedited site reuse or understanding potential liabilities associated with a property. We know how to tailor our approach to gather the necessary information, fully understand the problem, and guide the remediation strategy to efficiently meet our clients’ objectives and protect people and the environment.

Efficiently identifying human health and ecological risks

A focused risk assessment can mean the difference between a successful exit strategy or an endless series of evaluations and study. We concentrate our efforts on answering the important questions about risk and exposure to facilitate rapid, cost-effective, and protective cleanup or risk management strategies, not prolonged site investigation.

Risks to human health are influenced by the intended or current use of a site, the contaminants present, and the range of possible exposure pathways. Analyzing these factors is complicated by changing regulatory standards and focus at the state and federal level. The rise in concern over vapor intrusion and indoor air quality, for example, has led to new sampling methods, new phases of assessment, new agency scrutiny, and new litigation by tenants and owners. Our experts have the training and experience to quickly see to the heart of the issue and know how to apply proven methods of addressing risk to the health of building occupants or future users of a planned development. And we know how to communicate complex, risk-related issues in simple and effective terms to a variety of stakeholders and forums or as part of litigation support.

The ecology of a contaminated site and of the adjacent properties and waterbodies have a huge impact on site cleanup. Understanding the local conditions and the interconnected systems that may be impacted is essential to finding the right remedy. Our scientists have the training and hands-on experience to conduct comprehensive ecological assessments that accurately determine potential hazards and effects while offering alternatives on where to turn next.
