Investigation & Remediation

When working on site investigation and remediation projects, O’Brien & Gere’s Total Environmental Solutions Business Unit faces a number of challenges, such as: developing accurate and concise conceptual site models; negotiating clean-up levels and data quality objectives; readying sites for reuse and redevelopment (remediation, brownfields, liability/property transfers); balancing liability, regulatory, and cost considerations; applying the latest advancements in technology to enhance remediation; and working with multiple stakeholders.

In responding to these challenges, O’Brien & Gere starts by evaluating issues from the client’s point of view. Then, we develop site visions and exit strategies that capitalize on our 30 years of investigation and remediation experience as well as the strong relationships we have built with state and federal regulators. Finally, we concentrate on applying and selecting technologies that provide reasonable, cost-effective, and proven solutions for all involved stakeholders.
