Louisiana Hazardous Substance Emergency Events Surveillance

Since 1990, the Agency for Toxic Substances and Disease Registry (ATSDR) has maintained an active, state-based Hazardous Substances Emergency Events Surveillance (HSEES) system to describe the public health consequences associated with the release of hazardous substances except the release of petroleum. The Louisiana Department of Health and Hospitals, Office of Public Health, Center for Environmental Health Services, Section of Environmental Epidemiology and Toxicology (LDHH/OPH/CEHS/SEET) has participated in this surveillance system since 2001.

The HSEES system is designed to collect comprehensive data regarding the public health consequences of hazardous spills and/or releases. This program is funded by ATSDR through a cooperative agreement. SEET describes the immediate public health consequences of hazardous substance releases (e.g. injuries, medical care, evacuations, in-place sheltering) so that risk factors can be identified. These data are used to target prevention activities to reduce releases and the associated illnesses and deaths in employees, responders and the general public.


In 2000, LDHH/OPH established a workgroup with several industrial associations, the Louisiana State Police (LSP) and the Louisiana Department of Environmental Quality (LDEQ) to develop the HSEES system. Links to their websites are listed below.
