Site Assessment Health Consultations

Department of Health conducted health consultations from the early 1990's to 2017 as part of a cooperative agreement with the Agency for Toxic Substances and Disease Registry (ATSDR). We evaluated data about contaminants released into the environment, identified possible health hazards, and made recommendations to protect public health. In 2020, ATSDR renewed funding for DOH to continue this work. Past health consultations are available for your reference below. Select your county to view previous site information.
