Supply Chain Resilience Webinar

June 20, 2023, 1:00 - 2:00pm EDT

EPA’s Water Infrastructure and Cyber Resilience Division will be hosting a free webinar: Understanding Water Treatment Chemical Supply Chains and the Risk of Disruptions. This webinar will describe the impacts of chemical supply chain disruptions on the Water and Wastewater Systems Sector and the conditions that lead to these disruptions. The results of a relative risk evaluation will also be presented to highlight water treatment chemicals and precursors that may be at greatest risk of future supply disruptions. In addition, the webinar will cover recently developed water treatment chemical supply chain profiles and describe how they can be used by systems to improve their supply chain resilience. Documentation that can be used to apply for one hour of Continuing Education Units will be offered to those who participate for the duration of the webinar.
