Legal Counsel

Geosyntec provides specialized expertise to support lawyers as they counsel their clients and advocate for client interests on matters related to business transactions, environmental management, compliance and enforcement, toxic tort, and general litigation. Our focus extends from individual facilities to global company footprints, and we work comfortably with site operators and managers, while also being fluent in the language, goals, and needs of corporate executives.

Our people are qualified, experienced, and capable of addressing the most challenging problems in our principal areas of practice. Our practitioners quickly grasp the scope and nuances of key issues and develop sound, defensible technical insight for clients. Our senior staff includes engineers and scientists who are recognized authorities in their fields.

Many of our engineers and scientists have participated in key research and have pioneered technical approaches that now underpin their practices. Some were extensively involved in developing regulations and technical guidance. We continue to advance the state of the practice in areas such as geotechnical engineering, vapour intrusion, sustainability, innovative waste management approaches, and remediation of emerging contaminants.

With our support, clients navigate mergers, divestitures, and acquisitions (MD&A) by identifying salient liabilities and assessing their impacts on financial and business risk. Our assessments inform streamlined recommendations designed to enhance, not hinder, deal flow.

Our capabilities are far-reaching—domestically and abroad; our partnership with CAT Alliance ( provides an expanded network of over 10,000 professionals across over 50 countries to support clients in all aspects of due diligence from single-site transactions to large-scale portfolios in complex stock or asset deals.

Founded in 2001, CAT is a joint venture among three leading consultancies—COWI (Scandinavia and Eastern Europe), Geosyntec (North America, the United Kingdom, Sweden, and Southeast Asia), and Tauw (Southern and Western Europe). The alliance provides environmental due diligence to support large industrial, commercial-property, and financial clients. Specializing in corporate asset and transaction support, CAT has conducted environmental due diligence for more than 20,000 properties and has helped clients identify and recognize more than $100 billion in potential environmental liabilities as part of corporate transactions.
