Abstract: A Minnesota landfill inactive since 1962 was excavated in 1985 to prepare the site for construction of a new waste water treatment plant. The excavation refuse was disposed of in nearby sanitary and demolition landfills and in temporary and permanent on-site storage areas, depending on the physical characteristics of the materials. This approach to reclaiming the landfill site was the culmination of a series of investigations spanning 4 years and involving unprecedented cooperation to meet a community's need and protect the public interest. During excavation, work was observed full-time to target various types of refuse to the proper disposal locations. Also, air quality was monitored to detect volatile organic compounds in the excavation and at the property boundaries, and discharge from the dewatering system was sampled and analyzed. In general, preconstruction investigations were consistent with the results of our on-site monitoring activities.
