Sustainable Remediation Software Tool Evaluation

SiteWise proved to be the more flexible of the tools; it allowed the input of non-traditional remedial activities. However, this flexibility came at the cost of requiring more specific input data than SRT. SRT contained models of specific treatment technologies, which made the package more amenable to data-limited situations. The flexibility of SiteWise was highlighted by the Cu-surface water case study in that both contaminant and contaminated medium were not included in SRT’s models. This flexibility was also an advantage for SiteWise in modeling mercury-groundwater case study alternatives. The final case study of CVOC-groundwater started the tools on more equal footing, and the results of the two programs were generally within an order of magnitude of each other for the six impact categories that the programs shared.

Both tools addressed the SRI goals of minimizing footprint and managing risks by calculating those values, but not all of the goals were addressed by both programs. Although the tools were used partially outside of their intended scope, this study showed that the tools were useful for comparing remedial alternatives and can play an important role in the proliferation of green and sustainable remediation.
