River and Harbor Investigations

HAI's Litigation Research Division has helped a number of clients document the industrial development of river basins, waterways, and harbors in order to identify potentially responsible parties in environmental cost recovery actions, address Natural Resource Damage claims, and support other environmental litigation matters.

In one East Coast river basin project HAI utilized database technology to link digital images of nineteenth and twentieth century documents with abstracted information pertaining to industrial operations, waste disposal practices, and corporate succession. HAI also produced digital historical maps connecting documentary evidence to changes over time in the basin's industrial geography. The client subsequently used this data and information management system to identify other potentially responsible parties.

For a West Coast harbor case, HAI collected documentation of Corps of Engineers dredging and filling activities and worked closely with environmental consultants and attorneys to demonstrate that certain contaminated sediments could not be linked to a particular company's operations.

In other investigations HAI has traced the development of complex ocean outfall sanitation systems, gathered historical agricultural runoff, river flow, and water quality data, and uncovered evidence from contemporary literature that successfully established the historical baseline condition of rivers and harbors and documented changes in them over time.
