Since the early 1990s the U.S. government has been developing and implementing public policies that advance the
redevelopment of brownfields, and the recent passage of the Small Business Liability Relief and Brownfields
Revitalization Act (SBLRBRA) will significantly advance efforts to integrate environmental contamination
mitigation and redevelopment. Experience has demonstrated that successful redevelopment requires the collection,
analysis, and interpretation of environmental data in a timely and cost‐effective manner in order to allow
developers and lenders to efficiently use cleanup resources, develop response strategies that integrate cleanup
with redevelopment, and support meaningful outreach to involved stakeholders. Recent advances in the science and
technology of site characterization hold the promise of improved site characterization outcomes while saving time
and money. One such advancement, the Triad Approach, combines systematic up‐front planning with the use of
a dynamic field investigation process and the generation of real time data to allow in‐field decision
making on sample location selection.This article describes an application of the Triad Approach to redevelopment of an urban greenway in Trenton,
New Jersey. The Triad Approach, initiated through a partnership between the City of Trenton, New Jersey Department
of Environmental Protection, New Jersey Institute of Technology, and the U.S. Environmental Protection Agency,
demonstrated that this approach could accelerate the characterization of the 60‐acre, 11‐parcel
project area. Environmental issues that were solved using the Triad Approach included the delineation of the
extent of historic fill, determination of no further action for several areas of concern, detailed investigation
of specific impacted areas and the acquisition of sufficient data to allow the city to make important decisions
regarding remediation costs and property acquisition. © 2003 Wiley Periodicals, Inc.
