The efficacy of treatment systems in removing a range of emerging contaminants, such as microplastics, pharmaceuticals and personal care products, harmful algal blooms, 1-4-dioxane, and 6-PPD, from water is often unclear. States have expressed interest in understanding removal rates and viable treatment technologies to address public health concerns. This webinar will provide an overview of work by our Office of Research and Development to develop a framework of wastewater treatment processes, focusing on removal rates of certain emerging contaminants, as well as associated life cycle costs and environmental impacts. This work will give states and communities more resources to understand how to treat contaminants in their water systems, helping ensure clean water for all Americans.
