PUBLIC HEALTH ASSESSMENT

U.S. ARMY UMATILLA DEPOT ACTIVITY
HERMISTON, UMATILLA COUNTY, OREGON


COMMUNITY HEALTH CONCERNS

ATSDR investigated the issue of public health concerns through meetings, correspondence, telephone conversations and file information from the facility, EPA, CDC, state and local agencies. Specific community public health concerns raised have been related to the chemical weapons stored within UMCD. Although these concerns merit attention, it is not the purpose of this public health assessment to address the specific issues of chemical weapon storage and disposal. The U.S. Army is working in close coordination with the U.S. EPA, CDC, Oregon DEQ and local public health and emergency preparedness organizations to implement the safe demilitarization of these weapons, and to address emergency response considerations related to that activity.

HEALTH OUTCOME DATA

We did not evaluate health outcome databases because people were not exposed to site contaminants.

PUBLIC HEALTH ACTION PLAN

Conclusions

  1. Contamination in soil and groundwater do not represent past, present or future public health hazards, in that the potential for exposure of the public is nearly nonexistent.
  2. It will be necessary to provide verification groundwater monitoring, soil sampling and UXO surveys from remediated areas to provide information to support the decision process for future usage of areas released to the public.

Actions Planned

  1. The U.S. Army and regulators are enacting remediation activities to decrease or eliminate onsite contamination in soil and groundwater, and to decrease or eliminate the potential for migration of groundwater contaminants offsite from the facility.

Actions Recommended

  1. The Army should regularly monitor onsite groundwater supplies for contamination until verification of successful remediation. This will be of particular importance if future use plans includes development of shallow groundwater.
  2. Results of verification sampling and analyses conducted by the Army should be made available to the Oregon Economic Development Department to support the decision process in the determination of future land usage.
