As a successor to the HSEES program, ATSDR launched the National Toxic Substance Incidents Program (NTSIP) in 2009. One aspect of NTSIP is a national database of information related to chemical spills. NTSIP also has Assessment of Chemical Exposure teams to assist state and local health departments in the aftermath of toxic spills. These teams interview people who were exposed to the hazardous substances and collect samples to test the level of contamination in the environment and in people.
