    What is HSEES?

    The Hazardous Substances Emergency Events Surveillance (HSEES) system was established by ATSDR to collect and analyze information about acute releases of hazardous substances and threatened releases that result in a public health action such as an evacuation. The goal of HSEES is to reduce the morbidity (injury) and mortality (death) that result from hazardous substances events, which are experienced by first responders, employees, and the general public.

    What states currently participate in HSEES?

    Fourteen state health departments currently have cooperative agreements with ATSDR to participate in HSEES: Colorado, Florida, Iowa, Louisiana, Michigan, Minnesota, New Jersey, New York, North Carolina, Oregon, Texas, Utah, Washington, and Wisconsin.

    What is HSEES Role in Chemical-Related Counter terrorism?

    The US Department of Homeland Security has identified 3,400 chemical facilities that each could affect more than 1,000 people if attacked. The HSEES system data and prevention outreach are critical for identifying, preventing, and mitigating the consequences of terrorist threats against our chemical infrastructure. HSEES received $1,207,298 (Cooperative Agreements) in FY2005 and $780,200 (Cooperative Agreements and NRC) in FY 2006 from the Centers for Disease Control and Prevention’s Coordinating Office for Terrorism Planning and Response (COTPER) to partially fund the HSEES program.
