Environmental Site Investigation & Remediation

GZA's due diligence team meets the fast-track deadlines and demands of your real estate transactions. Our leadership in organizations like ASTM International and the Environmental Bankers Association keep us on the forefront of ever-changing standards and regulations.  We make it our priority to stay on the front line of emerging issues by actively participating in organizations like the Interstate Technology & Regulatory Council (ITRC) and various State-based professional organizations, where our influence can give voice to our clients' needs.  Our proficiency with advanced report preparation platforms reduces turnaround time and improves consistency and the quality of our work product. 

Site investigations and remediations are customized to meet each client’s goals, with the ultimate focus being what’s needed to efficiently close out the site under the regulatory options available.

For more complex sites, GZA has the expertise to manage and distill large data sets, evaluate potential human health and ecological risks to assess remedial need, conduct environmental modeling to assess current and potential future conditions under alternative scenarios, and prepare supportive graphics that present the results in a compelling manner.

We recommend the approach that best fits our client’s needs, taking into account relevant technical issues and regulatory requirements for the current and future use of the site. We use a full-range of remedial technologies from the traditional (e.g., excavation and containment remedies) to the more innovative (e.g.. phytoremediation, in-situ thermal treatment).

GZA has considerable experience identifying the sources of these complex chemicals, understanding the various PFAS migration pathways, and developing scientific and fiscally responsible approaches to address these environmental concerns.  GZA can help you assess whether, and when, you should test for PFAS; evaluate potential exposure pathways; navigate the rapidly changing regulatory landscape; and develop sound scientific approaches for mitigating potential environmental and health risks. We will be your responsible technical advocate, providing experienced and qualified personnel to help you address the regulatory, public relations, technical challenges, and risk management surrounding PFAS.

Contaminated sediment projects are complex, requiring multi-disciplinary teams to identify potential contaminant sources, to understand contaminant fate and transport, to assess human health and ecological risks, and to develop risk-based remedial designs.  The complexity of sediment projects tap many of GZA's strengths, including our client-focus and our exceptional strategic, communication, and advocacy skills.
