The Triad Approach was field‐tested to determine if characterization objectives could be met for a brownfields property that had been identified as a future elementary school site. The new school is in response to a New Jersey Supreme Court ruling (the Abbott decision) that directed the state of New Jersey to fund school construction in poorer districts to expand physical facilities to relieve overcrowding. The Triad Approach is promoted by the United States Environmental Protection Agency as a process that has the potential to improve the timeliness and efficiency of site characterization, and the New Jersey Department of Environmental Protection (NJDEP) recently issued a policy statement supporting its potential. Aggressive school construction deadlines are contingent on property acquisitions that are relatively faster than the traditional investigatory process. In addition, given the future sensitive population, the investigations must be thorough. This case study is among the first studies to document the use of the Triad Approach for a future school site. The Triad Approach was used to define site conditions for six areas of concern in a two‐month time frame (from the start of the planning process to completed investigation). © 2004 Wiley Periodicals, Inc.
A significant hindrance to reuse of Brownfield properties is the risk associated with redevelopment, specifically the uncertainty associated with environmental cleanup. This paper explores an approach to managing environmental risk through a combination of risk quantification, environmental insurance and the Triad Approach to site sampling and data interpretation. Using the Marsh Peer Review SM risk quantification process that employs statistical techniques and highly experienced technical staff the expected costs of environmental liabilities are estimated. The outputs of the process indicate premiums and attachment points for insurance products, but they also point to "critical uncertainties" that drive the insurance premiums. Insurance premiums are often linked to site delineation deficiencies, such as the magnitude of impacted soil or the size of a groundwater plume. The Triad Approach is an integrated site characterization process developed by the Environmental Protection Agency that combines systematic planning, dynamic or adaptive field decision-making and field analytical methods (FAMs). The real time data produced by FAMs allow for in-field resolution of uncertainty about sample location, which in turn provides more representative delineation of contaminant distribution. The trade-off of using slightly less accurate but substantially lower cost FAMs, is an increase in sampling frequency or density thereby reducing the risk of incomplete detection or delineation while yielding a "data set" that is more powerful than fewer individual data points analyzed through traditional methods. Employing the Triad approach to analyze the "critical uncertainties" identified in the Peer Review Process can impact insurance premiums and allow for better terms of coverage. The combination of using the Triad Approach and environmental insurance products can lead to more predictable and profitable Brownfield transactions.
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.
