Fugitive dust caused by infrastructure construction reduces air quality and may cause serious respiratory problems. Earthwork contractors apply dust control strategies to meet environmental regulations for dust mitigation. A life cycle sustainability assessment (LCSA) was performed to compare the impacts of two dust control methods: water application—currently considered the best available technology by industry—and enzyme-induced carbonate precipitation (EICP), a new bio-mediated technology being developed at Arizona State University. For each dust control method, indicators of...
