Site Assessment Health Consultations

Our Site Assessments Program 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 us to continue this work.
