Legal Support

EnviroForensics combines several of our core environmental services to develop unique, multi-component legal support through case expertise. Time and again, we have proven to be invaluable to our clients’ legal teams by providing The Best Science and the Best Strategy™ during litigation and remediation of environmental insurance, settlement negotiations and formal legal mediations.

Litigation Support

Our seasoned team of scientists, engineers and technical experts collectively hold 26 professional accreditations and advanced degrees, which includes LPG, PE, CHMM, MS, and makes up the scientific expertise we can provide clients during litigation. Our experts provide the knowledge and creativity to resolve complex contaminant fate and transport issues, answer timing of release questions, and envision strategic remediation solutions best suited for the situation at hand.

Chlorinated solvent contamination accounts for the bulk of our work. No other firm has closed as many sites with chlorinated solvent contamination as we have, and few possess the level of experience and expertise to handle the complicated and intricate challenges during the environmental investigation and remediation processes due to complications such as Dense Non-Aqueous Phase Liquid (DNAPL), Vapor Intrusion (VI) and Toxicological aspects.

Nation’s leading environmental engineering firm addressing the needs of the dry cleaning industry. We are a long standing and active member of dry cleaner associations and understand the potential challenges dry cleaners can go through during an environmental investigation and remediation. We care about the dry cleaners we serve and partner with them to anticipate potential challenges that lie ahead and provide them with proactive solutions. . Our close connection with the dry cleaning industry also has given us an extremely useful knowledge of the dry cleaning process itself and the changes in industry practices and equipment over the past decades. Our environmental and insurance based testimony have proven to be very helpful to our clients  by reconstructing the relationship between environmental site data and operational history during litigation.

Insurance Recovery projects comprise a significant portion of our project portfolio. This unique process allows us to assist our clients with transparent cost management and guidance of their environmental responsibilities. As a product of this business model, EnviroForensics staff are well-versed in dealing with insurance related issues. We also conduct Confidential Insurance Archeology® for property and business owners through our division, PolicyFind . Historical insurance archeology retraces the genealogy of insurance coverage to identify past owners and operators who may have contributed to or caused contamination. This rebuilding of historical land use and insurance coverage helps limit the liability of individual clients and their carriers, and can also initiate coverage from additional policies, thereby creating a larger reservoir of funds for equitable allocation. All of these services are under one roof, and as a result EnviroForensics understands the interconnectedness of environmental liabilities and insurance matters.

Project Life-Cycle Cost Analyses (LCCAs) are performed, and reserve estimates are prepared at strategic points for most all of our projects. Our remedial scientists and engineers have developed a proprietary method of quantifying the total environmental and financial risk to our clients to help them understand the entire lifecycle costs of environmental claims against them. We incorporate not only the likely cost of reasonable and necessary cleanup activities for sites in many different regulatory programs, but also the potential costs of third-party claims. Our Project LCCA and consultation has proven to be extremely helpful for our clients during litigation, mediation and settlement activities.
