From
January 2005 through September 2009, MDCH participated in a surveillance system for hazardous substances releases called Hazardous Substance Emergency Events Surveillance (MI-HSEES). The federally funded HSEES program included 14 other states that all used the same protocol to collect, analyze and disseminate data on acute chemical releases and related adverse health effects, and conducted interventions to mitigate the impacts of releases on environmental and human health. Annual reports were issued for each full year of data collection.
Beginning October 2009, MDCH is continuing with a scaled-back HSEES program as an unfunded state, along with seven currently funded states.
