HAI’s Litigation Support team offers comprehensive PRP (Potentially Responsible Party) and CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act) research to help businesses navigate environmental liabilities and Superfund cost recoveries. Our PRP searches involve thorough investigations utilizing extensive databases and historical records to identify entities responsible for environmental contamination. By partnering with History Associates, clients can manage environmental liabilities effectively and focus on their core operations with confidence.

Land Use, Watershed, and Site Histories

HAI’s expert Litigation Support team conducts in-depth research into historical land-use patterns by examining maps, zoning records, and property deeds to build a detailed narrative of a site’s usage over time. We also assess the impacts of past and current land use on water resources by collecting watershed data, including historical water flow patterns, water quality records, and ecological studies. Our site history investigations examine environmental reports, aerial photographs, and regulatory documents to uncover past activities that may have caused contamination or other environmental concerns.

Partnering with HAI’s Litigation Support team ensures businesses and legal teams have accurate, detailed historical insights to navigate complex environmental challenges. Our research supports legal strategies, regulatory compliance, and informed decision-making for site remediation and development projects.

Insurance Recovery Research

The HAI Litigation Support team specializes in insurance recovery research, providing services to help insurers and businesses navigate complex coverage disputes. Our expert team investigates publicly available records to establish an authoritative timeline of events associated with liability claims and other insured risks. Our detailed analysis ensures clients effectively assess liability by establishing the historical timeline, including knowledge and awareness, waste management practices, and triggering events.

Natural Resource Damages Evaluations

HAI’s Litigation Support provides historical research for site investigations, allocations, and toxic torts arising from NRD (Natural Resource Damages) claims. HAI’s historians specialize in reconstructing the site history by locating hard-to-find records to assist clients in building a solid factual foundation.

Federal Officer Removal Research

The HAI team leverages federal records expertise and in-depth knowledge of wartime contracting to document government control over production processes and waste disposal activities. Our research supports environmental law practitioners involved in retroactive liability settings where the U.S. government exercised substantial control over certain industrial facilities or operations and therefore should bear all or a portion of related environmental remediation costs.
