In 2017, a solar eclipse captured the interest of the U.S., with millions of people rushing to the so-called “path of totality”, which included parts of southern Illinois. The Illinois Department of Public Health and nearly a dozen county health departments across southern Illinois engaged in several days of emergency operations center activity. They relied heavily on a PHEP-funded web-based emergency management system to coordinate the event. PHEP supported partnerships with several volunteer teams that distributed water to help prevent heat-related illnesses as temperatures topped 90 degrees. As a result, southern Illinois safely accommodated approximately 250,000 visitors during the eclipse.

A water main break under a river contaminated water in Cumberland County, Illinois and left some residents without water entirely. In response, PHEP-funded health department staff established a water distribution center and went door-to-door to check on residents. The actions of the health department and the community spirit of the small town prevented any waterborne illnesses.
