Research Article: Identifying Historical Hazardous Waste Sites: Inputs to Urban Regeneration Planning

Our industrial legacy has left the nation with thousands of contaminated land parcels, known as brownfields, that must be rehabilitated and reintegrated into today's productive urban land inventory. This article presents a framework for site identification based upon the historical record, urban morphology, and hazard assessment. An eight-stage methodology is presented and applied to Keene, NH, a typical medium-sized industrial community in the Northeast. The framework proceeds where: (a) the industrial legacy is temporally demarcated; (b) the industrial legacy is spatially located; (c) relict hazards are identified; (d) quantities of waste produced are estimated; (e) toxicity is classified; (f) waste impacts are determined; and (g) a summative relict hazard waste map is produced as the initial input into a planning model, which project proponents/developers employ to determine the viability of site remediation and redevelopment. The framework's application in Keene, NH, demonstrates the viability of the methodology in delimiting potentially hazardous sites and thus advances predevelopment site identification and its position in brownfields planning.
