Chicago Water Week highlights critical water issues and the varied efforts to address them in ecological, industry, utility, research and entrepreneurial communities. Argonne National Labs is sponsoring three talks focusing on the vital role water plays in Chicago’s environment, communities, and economy. The first talk, “Chain Reaction Innovation (CRI) Water Company Showcase” showcases Argonne’s CRI program in assisting water startups toward commercialization of water technologies. Then, “PFAS Workshop,” will explore state-of-the-art research on PFAS toxicity, detection, separation, and destruction to enable water reuse. The final talk, “Oceanshot Webinar,” will center around the effective utilization of ocean resources and the role of the ocean in climate modulation and decarbonization.
