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. Sites like this one are not uncommon throughout the United States as urban development reaches out to formerly rural areas near former MGPs. Thousands of similar sites are found across the United States, many of which have gone without mitigation because of similar issues in terms of the complexity and the contaminant distributions and political considerations making resolution of reuse issues perplexing. In this case study innovative technologies and strategies are discussed, which can help others with similar sites begin to address stakeholder concerns in a streamlined and economic fashion.
