Regulations, innovations in techniques or technologies, and site conditions, among other things, can impact the effectiveness of a remedial design over time. These changes may result in rising remedial costs, decreased results, and inability to move toward an endpoint. Without revisiting the design, opportunities for improvement may be overlooked. Woodard & Curran had developed a pragmatic strategy to optimize remediation and expedite exit from the contaminated site. This starts with a four-pronged assessment of current conditions to determine any gaps in the conceptual site model (CSM) and lays the foundation for developing a more effective approach. This free white paper outlines the process of how optimizing remedial efforts can lead to a quicker exit plan or alternative endpoint. While applicable to most sites, an experienced team will be able to conduct a detailed evaluation and provide concrete benefits reflected in reduced costs, increased sustainability, and shorter project turn around.
