PUBLIC HEALTH ASSESSMENT

FORT EUSTIS (US ARMY)
NEWPORT NEWS
NEWPORT NEWS COUNTY
VIRGINIA




CONCLUSIONS

      Biota (catfish) samples from Eustis Lake, Bailey's Creek and Brown'sLake contain elevated levels of PCB. Additional information was collectedat Eustis Lake by the U.S. Army. These samples detected PCBs in severalspecies of fish. Catfish, shad and carp should not be eaten. Bass and crappieconsumption should be limited. Fishing restrictions in place at Fort Eustisprohibit consumption, and are therefore protective of human health. No additional sampling is planned for Bailey's Creek. Fish from Bailey'sCreek should not be consumed, at least unless further information is obtainedto clarify PCB levels in fish. Plans are in place to prohibit fishing inthis water body. Consumption of fish from Brown's Lake should continue to be prohibited.Given the in-place and planned fishing restrictions at Fort Eustis,consumption of biota represents No ApparentPublic Health Hazard.
    • There does not appear to be a significant amount of contaminationin surface water in Fort Eustis. An exception was the TPH contaminationat Milstead Island Creek. However, based on the results of the supplementaryRI conducted in this area, there does not appear to be a current publichealth hazard. Based on this information, surface water contaminationof Milstead Island Creek is considered No Apparent Public Health Hazard.Biota contamination in Eustis Lake suggests surface water or sedimentmay be contaminated. It is unlikely that PCB contamination is high enoughthat recreational (infrequent and short-term exposure) would result ina public health hazard. Surface water in Eustis Lake represents No ApparentPublic Health Hazard. The Warwick River does not appear to be contaminated by chemicals fromFort Eustis IRP sites and presents No Apparent Public Health Hazard.Surface water at Fort Eustis presents No Apparent Public Health Hazard.
  1. Groundwater under Fort Eustis is locally contaminated. This wateris not used by the post for drinking water, so does not pose a hazard topublic health. The contamination is localized to the immediate vicinityof sources, and is not a threat to reach the main portion of the York-JamesPeninsula. Groundwater contamination at Fort Eustis presents No ApparentPublic Health Hazard.

  2. Sediment contamination exists within Fort Eustis. The area with thehighest levels of sediment contamination is Bailey's Creek. Lead and PCBsare the primary contaminants. However, there does not appear to be an completedsediment exposure pathway. Therefore, sediment at Fort Eustis presentsNo Apparent Public Health Hazard.

  3. Soil contamination at Fort Eustis appears to be localized withinrelatively small areas. Access to these areas is limited by institutionalcontrols. There do not appear to be completed exposure pathways relatedto soil contamination. Therefore, soil at Fort Eustis presents No ApparentPublic Health Hazard.

  4. There is no evidence of an air exposure pathway at Fort Eustis. Therefore,the air exposure pathway represents No Apparent Public Health Hazard.

  5. A summary of the exposures situations evaluated is shown in Table3.

* exposure indeterminate - information is not available to evaluate potential exposure, ** "controlled" - institutional controls (fences, signs, etc) have eliminated possibility of exposure, *** - "exposure unlikely" - exposure to hazardous chemicals not likely to occur.

RECOMMENDATIONS

The Comprehensive Environmental Response Compensation, and LiabilityAct (CERCLA; also known as Superfund) as amended, requires ATSDR to conductneeded follow-up health actions in communities living near hazardous wastesites. To identify appropriate actions, ATSDR created the Health ActivitiesRecommendation Panel (HARP). HARP has evaluated the data and informationcontained in the Fort Eustis Public Health Assessment for appropriate publichealth actions. HARP supports the continuation of restrictions placedon fishing in the contaminated water bodies. Based on the information available,this site poses no apparent public health risk. If additional informationbecomes available that may indicate a public health risk, this informationwill be evaluated by the HARP. HARP determined that health education andhealth studies follow-up actions are not warranted. As discussed above,there do not appear to have been exposures in the past which resulted inpublic health problems, and there are no current exposures.

  1. Institutional controls, such as warning signs, should remain or beput in place at Brown's Lake, Bailey's Creek and Eustis Lake. If thesesigns do not prohibit fishing, they should require catch-and-release fishing.

  2. Institutional controls should remain in effect at all areas documentedby the remedial investigation to contain environmental contamination orphysical hazards until the potential for public health hazard is eliminated.

  3. Sampling of the tributaries of the Warwick River should continueas planned to verify that contaminants are not reaching that river in significantquantities.

PUBLIC HEALTH ACTIONS

The public health action plan (PHAP) for Fort Eustis, Virginia NPL sitecontains a description of actions to be taken by ATSDR and/or other governmentalagencies at of the site and in the vicinity subsequent to the completionof this public health assessment. The purpose of PHAP is to ensure thatthis public health assessment not only identifies public health hazards,but also provides a plan of action designed to mitigate and prevent adversehuman health effects that would result from any exposure to hazardous substancesin the environment. Included is a commitment on the part of ATSDR to followup on this plan. The public health actions to be implemented are as follows:

Actions Recommended or Planned

  1. The Army should maintain institutional controls to restrict the possibilityof access to IRP sites that might present physical hazards, and shouldenforce the fishing advisory at Brown's Lake, Bailey's Creek and EustisLake. This advisory should include maintenance of warning signs at thesewater bodies, as well as distribution of information material at recreationcenters, security offices and environmental-public safety offices.

  2. ATSDR will review the remedial activities at Fort Eustis, to evaluatethe proposed remediations in relation to protection of public health. ATSDRcomments and recommendations, as appropriate, will be provided to EPA,the Army and State of Virginia.

Action Taken In Response to ATSDR Recommendations

  1. Edible fish tissue samples were collected and analyzed at EustisLake.

  2. Prohibitions on fishing from Eustis Lake and Bailey's Creek havebeen enacted or are planned.

  3. Supplementary information on TPH contamination has been collectedat Milstead Island Creek. No TPHs were found above the detection levelof 0.5 ppm.

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.
