PUBLIC HEALTH ASSESSMENT
FORT RICHARDSON (U.S. ARMY)
ANCHORAGE COUNTY, ALASKA
- The primary issue regarding public exposure to hazardous chemicals at FortRichardson is that of white phosphorous-contaminated waterfowl from EagleRiver Flats. Studies of waterfowl collected in the vicinity have notdetected the presence of white phosphorous. Therefore, this exposurepathway is considered to be No Apparent Public Health Hazard.
- Physical hazards such as derelict structures and open pits exist at FortRichardson. However, institutional controls are in place to preventpublic access. Therefore, this exposure pathway is considered to be NoApparent Public Health Hazard.
- Asbestos has been found in abandoned structures at Fort Richardson. Access to these structures is limited by institutional controls. Therefore, this is considered to be No Apparent Public Health Hazard.
The Comprehensive Environmental Response Compensation, and Liability Act(CERCLA; also known as Superfund) as amended, requires ATSDR to conduct neededfollow-up health actions in communities living near hazardous waste sites. Toidentify appropriate actions, ATSDR created the Health ActivitiesRecommendation Panel (HARP). HARP has evaluated the data and informationcontained in the Fort Richardson Public Health Assessment for appropriatepublic health actions. Based on the information available, this site poses noapparent public health risk. If additional information becomes available thatmay indicate a public health risk, this information will be evaluated the HARP.HARP determined that health education and health studies follow-up actions arenot warranted. As discussed above, there do not appear to have been exposuresin the past which resulted in public health problems, and there are no currentexposures.
- Fort Richardson should continue to monitor institutional controls atcontamination sites and at abandoned facilities to ensure that publicaccess is eliminated. Institutional controls should remain in effectuntil the potential for public health hazard is eliminated.
- ATSDR will evaluate future remedial investigation data to update ourexposure evaluation.
The public health action plan (PHAP) for Fort Richardson, Alaska NPL sitecontains a description of actions to be taken by ATSDR and/or othergovernmental agencies at and in the vicinity of the site subsequent to thecompletion of this public health assessment. The purpose of PHAP is to ensurethat this public health assessment not only identifies public health hazards,but provides a plan of action designed to mitigate and prevent adverse humanhealth effects would result from any exposure to hazardous substances in theenvironment. Included is a commitment on the part of ATSDR to followup on thisplan. The public health actions to be implemented are as follows:
- ATSDR will evaluate future remedial investigation data to assure that anaccurate exposure evaluation has been made.
- The Army should continue to maintain institutional controls to restrictthe possibility of access to OUs that might present physical hazards.
- ATSDR will review the remedial activities at Fort Richardson, to evaluatethe proposed remediations in relation to protection of public health. ATSDR comments, and recommendations, as appropriate, will be provided toEPA, the Army and State of Alaska.
