This case study examines how systematic planning, an evolving conceptual site model (CSM), dynamic work strategies, and real time measurement technologies can be used to unravel complex contaminant distribution patterns and design a remedy at the Cache La Poudre (Poudre) River site. The investigation and design of the remedy involved a former burn landfill, hydrocarbon fuel contamination, and mobile manufactured gas plant (MGP) coal tar waste. The remedy was driven by recreational reuse and proximity to the Poudre River. The remedy involved pathway elimination and stream restoration in a location central to the City of Fort Collins, Colorado.You may need a PDF reader to view some of the files on this page.
