The Agency for Toxic Substance and Disease Registry (ATSDR) is a part of the Center for Disease Control (CDC) which is operated by the Federal Department of Health and Human Services (DHHS). The ATSDR received a request to conduct a public health assessment at the Santa Susana Field Laboratory (SSFL). ASTDR held meetings with the public in the Fall of 1999 to identify health concerns and completed a preliminary site evaluation in December 1999.
The preliminary site evaluation executive summary states that "preliminary results of the exposure pathway analyses for air, ground water and surface water, and soil and sediment indicate that it is unlikely that people living in communities near the site have been exposed to substances from the site at levels that would have resulted in adverse health effects".
The ASTDR recommended further studies to assess potential off site exposure pathways to contaminants, update the prior state cancer registry studies, and perform public outreach. As a result, ATSDR contracted with the Eastern Research Group (ERG), who in turn issued a sole source contract to the University of California at Los Angeles (UCLA) to assess potential off site exposure.
