3 Health Assessment and Toxicology (HAT) State Mandate: Responsible for taking the lead in assessing the potential adverse health effects that exposure to toxic substances or harmful physical agents may have on people Health and Safety Code, Title 6, Chapter : Health Risk Assessments Title 2, Subtitle H, Chapter , subchapter C: Epidemiology or Toxicology Investigations

physical agents may have on people Health and Safety Code, Title 6, Chapter 503.

4 Agency for Toxic Substances and Disease Registry ATSDR entered into a Cooperative Agreement with DSHS to assess the presence and nature of health hazards at Superfund sites.

5 Goals of HAT reduce and prevent adverse human health conditions from toxic environmental exposures identify human populations at risk community involvement in areas with hazardous waste sites educate communities on exposure prevention and pathways health care professional education

community involvement in areas with hazardous waste sites educate

6 Customers Federal/State agencies City and County officials Community residents/citizens Health professionals DSHS internal programs Media

7 Cooperative Agreement with ATSDR Conduct Public Health Assessments and Health Consultations on hazardous waste sites listing on National Priorities List (Superfund) petitioned by community members specific request from another government agency
