PETITIONED PUBLIC HEALTH ASSESSMENT

COUNTRY CLUB LAKE ESTATES
HATTIESBURG, FORREST COUNTY, MISSISSIPPI


CONCLUSIONS

  1. The lakes on Mineral Creek near Hattiesburg, Mississippi, represent a public health hazard because the levels of pentachlorophenol, dioxins, and furans present in the fish exceed public health guidelines. Fish consumption is the most hazardous completed exposure pathway. Other possible exposures of health concern are exposures to contaminated off-site sediments and on-site soils.
  2. Current data are insufficient to determine the extent of contamination in fish downstream of Country Club Lake or whether consumption of those fish presents an increased cancer risk.
  3. Data inadequacies include the following:
    1. The actual extent of groundwater contamination has not been identified.
    2. Off-site surface water samples have been analyzed for polychlorinated dioxins and furans; however, analytical detection limits were higher than current laboratory standards; thus ATSDR's evaluation of the dioxin and furan data is limited for off-site surface water.
    3. Additional monitoring of fish tissue downstream of Country Club Lake is necessary to determine the current geographical range of contaminated fish.
    4. Additional sampling of on-site surface soil is needed to better characterize the extent of contamination.
    5. Further research is needed to determine possible healtheffects and environmental and health guidelines for 2-methylnaphthalene.

RECOMMENDATIONS

Cease/Reduce Exposure Recommendations

  1. Consumption of fish from Country Club Lake should be banned until additional analyses of fish indicate ingestion of fish is safe.
  2. Public access should be restricted from the on-site contaminated soil and sediments.
  3. Employee exposure to on-site contaminated soil should be minimized or prevented.
  4. Off-site migration of contaminants, particularly surface-waterrunoff and erosion of soil, should be minimized.

Site Characterization Recommendations

  1. A representative number of fish should be sampled from the waters of Mineral Creek, and near the confluence with Bowie River, to define the geographical range of pentachlorophenol and dioxin contaminated fish.
  2. For future monitoring pentachlorophenol and polychlorinated dioxin and furan analyses of fish, collected from the defined geographical range, should be conducted to establish the existence or trend of contamination (e.g., decreasing number of contaminated fish, decreasing concentrations, etc.).
  3. Fillet sampling should be conducted to evaluate the edible portions.
  4. Sediment samples should be collected from around the lakes and other popular stretches along Mineral Creek where human contact is most likely to occur. If concentrations are significant at the juncture of Mineral Creek and Bowie River, then sampling should be continued downstream to characterize the extent of contamination. All sediment samples should be analyzed for pentachlorophenol, polychlorinated dioxins and furans.
  5. The two Johnson Utility Company wells near the site should be analyzed for pentachlorophenol and polychlorinated dioxins and furans. Similar sampling should be done for the Arnold Line wells, if groundwater characterization indicates off-site groundwater contamination near the Arnold Line wells.
  6. On-site groundwater should be characterized to establish groundwater flow direction and any contamination plume that may exist. Off-site groundwater characterization should be conducted, if necessary, to define the extent of contamination.
  7. The private drinking water well near the site should be analyzed for polychlorinated dioxins and furans. If contamination is detected, further work (sampling or modeling) to define the extent of contamination and closure of the well should be initiated.
  8. Soil samples should be collected from areas of the golf course where irrigation from the pond was most widely used. The soil samples should be analyzed for pentachlorophenol and polychlorinated dioxins and furans.
  9. A representative number of on- and off-site subsurface andsurface soil samples surrounding the site should be analyzedfor pentachlorophenol and polychlorinated dioxins and furansto define the depth and geographical range of contamination.

HEALTH ACTIVITIES RECOMMENDATION PANEL RECOMMENDATIONS

Data and information developed in the Country Club Lake EstatesPetitioned Public Health Assessment have been evaluated by theHealth Activities Recommendation Panel for appropriate publichealth actions. Possible exposures to contaminants pose a publichealth threat. The Health Activities Recommendation Panelbelieves that the potentially exposed population needs assistancein understanding their potential for exposure and in assessingany possible adverse health effects in their community. Therefore, the panel recommends community health education as ahealth follow-up action. ATSDR should interact with thecommunity and the state to provide needed information and to seekfeedback from residents about their concerns and informationneeds. Because the population exposed is not well defined, andthe levels and duration of exposure are not known, health studiesare not indicated at this time. ATSDR will evaluate any new dataor information it receives about this site to determine whatpublic health actions, if any, might be appropriate.


PUBLIC HEALTH ACTIONS

The actions described in this section for Country Club LakeEstate are actions that will be taken by ATSDR. The purpose ofthis plan is to ensure that the petitioned public healthassessment not only identifies public health hazards, butprovides a plan of action designed to mitigate and preventadverse human health effects resulting from exposure to hazardoussubstances in the environment. The public health actions to beimplemented by ATSDR are as follows:

  1. The Agency will provide environmental health education for the community to make them aware of the possible hazards present, the likelihood of exposure, and to assist the community in assessing possible adverse health outcomes associated with exposure to hazardous substances.
  2. ATSDR will contact appropriate federal and state officials to obtain additional data or new data as it becomes available. ATSDR will ensure recommendations made in this petitioned public health assessment are forwarded to the appropriate agencies for action.
  3. If any new data are found to be of significant public health concern, the Division of Health Assessment and Consultation will revise the Country Club Lake Estates Petitioned Public Health Assessment as appropriate.
  4. The Mississippi Department of Environmental Qualityproposes to conduct sampling of soil at the golf course,sediment at the golf course irrigation pond, and anyutility wells within a mile radius of the site forpentachlorophenol, dioxins, and furans. The drinking waterwell closest to the site will be sampled for dioxins andfurans.

ATSDR will reevaluate and expand its Public Health Actions whenneeded. New environmental, toxicological, or health outcomedata, or the results of implementing the above proposed actions,might determine the need for additional actions at this site.
