Entitled, “ATSDR Focuses on Exposure to Contaminants”, this image was captured by ATSDR, Emergency Response Coordinator, in the Division of Toxicology and Environmental Medicine, Larry Cseh, RS, MSA (CAPT, USPHS). The image depicts two ATSDR staffers conducting a site evaluation on the Hopi Indian Reservation in Arizona. The Hopi Tribe, and the Bureau of Indian Affairs (BIA) asked ATSDR to assist them in developing screening levels for site evaluations of sheep dip vats located on their reservation. ATSDR also reviewed results of soil and groundwater samples, also obtained from the Hopi Reservation, and provided a public health opinion regarding exposures to their reported contaminants. This photo earned CAPT Cseh a tie for the Third Place award in the 2008 CDC Connects Annual Public Health in Action Photo Contest, in the category of “Domestic Programs”.
