Why is ATSDR assessing the site after cleanup activities have begun at the site?
ATSDR’s involvement at Andersen AFB focuses on public health (i.e., the health impact on the community as a whole). In evaluating potential public health hazards, ATSDR reviewed available environmental data, both available pre-and post remediation data, as well as any proposed remedial actions. Our review of the available data shows that people have not come in contact with, nor are they expected to contact, hazardous substances from Andersen AFB at levels posing potential public health hazards. Therefore, based on the available data, regardless of the stage of investigation, contamination from Andersen AFB poses no public health hazard. ATSDR is an advisory agency, so if hazards were identified, the PHA would recommend appropriate actions, such as additional cleanup measures, to be undertaken by responsible parties. Site characterization and remediation at NPL sites may continue for years after releases are suspected. Likewise, remediation may occur before or after ATSDR’s involvement
