The Agency for Toxic Substances and Disease Registry (ATSDR), a public health agency of the U.S. Department of Health and Human Services, today is issuing for public review and comment a public health assessment for the Volunteer Army Ammunition Plant (VAAP) in Chattanooga, Tenn.

The public comment period extends through July 7, 2004. The public health assessment is available for review at the local repository. Its findings will be presented by an ATSDR representative at a June 17 meeting of the Restoration Advisory Board for the VAAP site.

The purpose of this public health assessment is to evaluate potential sources of contamination associated with the Volunteer Army Ammunition Plant and to identify potential exposure pathways in the surrounding communities. The most common contaminants at the base are related to the historical production of trinitrotoluene (TNT). Other contaminants identified at some on-site locations include volatile organic compounds (VOCs), pesticides and metals.

ATSDR's review of available information indicates that people residing near the plant are not currently being exposed to site-related contaminants at levels that could result in adverse health effects. Because of insufficient sampling data it is not possible to completely evaluate the potential for exposure while the plant was producing TNT.

After evaluating available environmental information, ATSDR has drawn the following conclusions:
" Residents might have had limited exposure to some of the contaminants identified in the soil, surface water or sediment; however, the exposure is not expected to cause health effects.
" While the base was actively producing TNT, local residents might have been exposed to nitrogen and sulfur oxide air emissions. These types of exposures are known to cause short-term respiratory effects. However, there is not enough data to identify if long-term health effects could result from that exposure.
" Some groundwater contaminants migrated off-base. There is not enough sampling data to identify if residents were exposed to some of the contaminants in the groundwater while they were using private groundwater wells for their drinking water. Currently all residents are believed to be connected to the municipal water system, which provides clean drinking water that meets federal, state and local standards.

Further public health actions and recommendations are available in the complete public health assessment.

The public health assessment may be reviewed through July 7, 2004, at the
Chattanooga-Hamilton County Bicentennial Library
