PRELIMINARY PUBLIC HEALTH ASSESSMENT

AMERICAN CREOSOTE WORKS, INCORPORATED
(WINNFIELD PLANT)

WINNFIELD, WINN PARISH, LOUISIANA


CONCLUSIONS

Based on the information provided and reviewed by SEE it is concluded that the AmericanCreosote site poses a public health hazard because of past, and possibly present and future,exposure to on-site soil, sediment, and surface water contaminated with PAH's, PCP, and dioxin. The exposures are estimated to be at levels that could exceed, individually or as a mixture, long-term health guidelines.

Completed exposure to these chemicals on the site and at the Creosote branch probably haveoccurred via incidental ingestion and dermal contact with soil, sediment, surface water andinhalation of air. Potential exposure may occur via ingestion and dermal contact with soil,sediment at Port du Luce, ingestion of biota at Creosote Branch and Port du Luce, and inhalationof fugitive dust, however, sampling data on biota, residential yards, and fugitive dust have notbeen collected. The population at highest risk of exposure are residents particularly children wholive adjacent to American Creosote and play at the banks of Creosote Branch, residentstrespassing the site or living at the site border, and residents involved in recreational activities atthe Creosote branch and Port du Luce.

Currently groundwater represents no health threat because no public wells are installed in thecontaminated shallow aquifer, i.e, 5 to 30 feet deep. Potential exposure to contaminatedgroundwater would be possible if contamination does migrate off the site and residential wellswere installed within the contaminated area or if the shallow aquifer is used as a source of potablewater.

The site is open, flat, and sparsely vegetated, therefore during dry, windy periods, contaminatedparticulates must be considered a potential threat to the residents adjacent to the site. The limitedair data is insufficient to draw health conclusions


RECOMMENDATIONS

  1. Site access should be restricted and the public should be educated not to trespass the site and that no children should play in Creosote Branch and downstream of Creosote Branch. Warning signs identifying American Creosote as a hazardous waste site should be increased and placed evenly and visibly throughout the area.
  2. Persons on the site and off the site, should be protected from exposure to dusts or vapors that may be released during remediation.
  3. Sampling of residential surface soil, additional off-site sediments, and off-site surface water is recommended to adequately characterize the extent and amount of site contamination that may exist off the site. Samples of sediment and surface water from Port du Luce Creek should be taken.
  4. Continuous air monitoring during remediation activities is recommended.
  5. Appropriate measures should be instituted to assure groundwater contamination does not migrate off the site and that the shallow aquifer will not be used as a water source.
  6. Off-site sampling of aquatic biota and game should be conducted, since the area is used for recreational activities. Information should also be collected about consumption of commercial fish and other aquatic organism.
  7. Workers should adhere to the existing safety plan in accordance with applicable Occupational Safety and Health Administration regulations.
  8. Cancer mortality data should be reviewed, as soon as it becomes available.

Health Activities Recommendation Panel Statement

In accordance with the Comprehensive Environmental Response, Compensation and Liability Act(CERCLA) of 1980, as amended, the data and information developed in the American Creosotehealth assessment have been evaluated by the Health Activities Recommendation Panel (HARP)for appropriate follow up health actions. The HARP concluded that:

  1. Health professions education program should be offered to local public health officials and the medical community to advise them of the nature and potential health effects of exposure to the site's contaminants.
  2. Community health education program should be conducted to inform area residents about the nature of the site and potential health effects resulting from exposure to contaminants.
  3. There are indications that people have been exposed to site contaminants in the past and probably continue to be exposed. This site should be considered for inclusion in an ATSDR multi-site study of health effects and wood treating facilities.
  4. Because of area residents' concerns of possible site-related cancers and other diseases, HARPdetermine that a health statistics review should be conducted on cancer data and any otheravailable health outcome data.

As additional data become available suggesting human exposure to hazardous substances isoccurring, ATSDR and SEE will reevaluate this site for additional follow up activities.

Public Health Actions

The following are a description of actions to be taken by ATSDR and the SEE at the AmericanCreosote site and surrounding areas. The purpose is to ensure that this public health assessmentnot only identifies public health hazards, but provide a plan of action designed to mitigate andprevent adverse human health effects resulting from exposure to hazardous substances in theenvironment. Included is a commitment on the part of ATSDR/SEE to follow up on these actionsto ensure that they are implemented. The public health actions to be implemented byATSDR/SEE are as follows:

Actions Planned

  1. An environmental health education program is planned to advise the public health professional and the local medical community of the nature and possible consequences of exposure to contaminants at the American Creosote site. The value of obtaining a complete and accurate exposure history will be stressed as part of this program. In addition, information that is provided on the contaminants of concern may include, but not be limited to, the physical nature of the contaminant, potential health effects, symptoms of exposure and testing and treatment, if known. This activity will be conducted by SEE with the assistance of ATSDR Division of Health Education.
  2. SEE, in cooperation with ATSDR, will conduct a health education program to advise the community of the possible consequences of exposure to contaminants at the American Creosote site. Actions which can lessen exposure will be stressed.
  3. SEE will review and evaluate parish health statistics for cancers and other illnesses as they become available.
  4. SEE and ATSDR have a continuing role to play as an advisor and source of information for the community surrounding the American Creosote site. In this capacity, SEE/ATSDR will continue its dialogue with the community, working to provide needed health information and other site issues, and to seek feedback from residents about concerns and information needs. LOPH will conduct a public meeting at the local parish unit in Winnfield to explain the results of the Preliminary Public Health Assessment.
  5. ATSDR/SEE will cooperate with U.S. EPA and the Louisiana Department of Environmentalquality to implement other site characterization actions.

These Public Health Actions will be evaluated annually unless additional information warrantsmore frequent evaluation.
