Our Expertise

As one of the most experienced teams in the country, TIG Environmental specializes in the use of sophisticated investigative techniques, evidence gathering, and environmental forensic analyses to support clients involved in complex, multi-party sites with contaminated sediments, soils, or groundwater. We gather historical, factual evidence to establish a basis for cost allocation and then perform forensic analyses to develop defensible, fact-based, and successful cost allocation proposals.

TIG Environmental uses environmental forensics to support site investigation and delineation, source identification, and allocation. We recognize that each situation is unique. By using a weight-of-evidence approach, we can design and execute each analysis to meet the project’s specific objectives.

Access to high quality information is essential for making sound data-driven decisions. TIG Environmental’s data and analytics experts develop the data, analytics, and technologies that empower our clients to make better and faster decisions with more confidence.

TIG Environmental has a proven track record of providing customized cost-effective solutions to our clients on environmental matters for over 20 years. Specializing in sediment and urban waterways, TIG Environmental’s multi-disciplinary team of professionals provide expert support on remedial planning, design and implementation support, cost recovery, and litigation matters. Our mission is simple: drive maximum value and efficiency into the remedial process to minimize our client’s overall exposure.

The world of contaminated sediment management is changing fast. Waterfront revitalization is driving the need to address legacy sediment contamination in urban areas. Regulatory agencies and the communities they serve are demanding more rigorous cleanups with features that can dramatically drive up complexity and cost. At the same time, there is increasing pressure for source identification and control. With the cost of some cleanups well into the billions of dollars, cost allocation has transformed into an intricate, high-stakes enterprise. Whether you need a few days of strategic consultation, support in allocation or litigation, or technical studies at any stage of project development, TIG Environmental makes the difference.

TIG Environmental’s experts are leaders in evaluating legacy and emerging contaminants in the environment. Our experts have decades of experience and knowledge discerning sources and the fate of polychlorinated biphenyls (PCBs), dioxins and furans (PCCD/Fs), polycyclic aromatic hydrocarbons (PAHs), as well as mercury and other metals in rivers, lakes, ports, harbors, groundwater, and soils. Additionally, we support clients in developing strategies and forensic methodologies related to emerging contaminants such as per- and polyfluoroalkyl substances (PFAS). We understand the unique challenges associated with the forensic evaluation of legacy and emerging contaminants and recognize the need to use an integrated approach to evaluate multiple lines of evidence. Our expertise in forensics and source identification integrates with TIG Environmental’s other areas of expertise to provide end-to-end litigation and mediation support, including: 

• Identifying and modeling release pathways and fate transport processes 

• Performing multivariate analysis and other forensic data analytics 

• Identifying the presence of unique chemical markers including impurities and/or the presence of specific isomers 

• Evaluating onsite and offsite historical operations and infrastructure 

• Researching trade, scientific, historical, and regulatory documents to create inventories of potential contaminant sources as well as identify witnesses, unique records, and other factual evidence not uncovered through formal civil discovery 

• Developing and evaluating evidentiary databases using commercial platforms; triaging and prioritizing content contained in incoming discovery productions using our Triage and Intelligence Gathering e-Discovery Routine (TIGER) 

• Developing, managing, and vetting witness pools; tracing and evaluating complex corporate transactions; and locating evidence of potential insurance coverage
