PUBLIC HEALTH ASSESSMENT
USA DEFENSE DEPOT MEMPHIS
MEMPHIS, SHELBY COUNTY, TENNESSEE
CONCLUSIONS
The environmental routes, as shown in Figure 1 have been evaluated by ATSDR , using environmental information collected during the remedial process. The following are conclusions reached by the ATSDR following this evaluation. The numbers refer to the numbers of the routes as shown in Figure 1.
The onsite drainage ditch water contains low levels of VOCs, metals, petroleum products and pesticides. These levels are not sufficient to cause a threat to public health from dermal contact. Additional sampling scheduled for summer of 1995 will provide further information.
Information is needed on extent of surface soil contamination resulting from sandblasting operations at DDMT. This information will address the issue of possible offsite air transport of metals from these operations.
Community concerns have been expressed about public health effects: from contamination in drainage ditches and from food grown in areas near these ditches; from contaminated groundwater; and from mustard gas destroyed and disposed at DDMT in 1946, as well as other chemical agents disposed at Dunn Field.
ATSDR Conclusion Categories of No Apparent Public Health Hazard have been assigned to all of the environmental routes. Table 3 provides additional details on each of the routes.
-- * "controlled" means that institutional controls (fences, paving, other measures) have eliminated possibility of significant exposure. ** -- "exposure unlikely" means that significant exposure (resulting in public health problem) to hazardous chemicals not likely to occur.
RECOMMENDATIONS
The Comprehensive Environmental Response Compensation, and Liability Act (CERCLA; also known as Superfund) as amended, requires ATSDR to conduct needed follow-up health actions in communities living near hazardous waste sites. To identify appropriate actions, ATSDR created the Health Activities Recommendation Panel (HARP). HARP has evaluated the data and information contained in the DDMT Public Health Assessment for appropriate public health actions. HARP determined that health education and health studies follow-up actions by ATSDR are not warranted. There do not appear to have been exposures in the past which resulted in public health problems, and there are no current exposures.
PUBLIC HEALTH ACTIONS
The public health action plan (PHAP) for the Defense Depot Memphis Tennessee NPL site contains a description of actions to be taken by ATSDR and/or other governmental agencies at and in the vicinity of the site subsequent to the completion of this public health assessment. The purpose of PHAP is to ensure that this public health assessment not only identifies public health hazards, but provides a plan of action designed to mitigate and prevent adverse human health effects that would result from any exposure to hazardous substances in the environment. Included is a commitment on the part of ATSDR to follow-up on this plan. The public health actions to be implemented are as follows:
Actions Planned
ATSDR will reevaluate and modify the Public Health Action Plan as needed. New relevant data, or the results of implementing the above proposed actions may determine the need for additional actions at this site.
