PUBLIC HEALTH ASSESSMENT ADDENDUM

CAROLAWN
FORT LAWN, CHESTER COUNTY, SOUTH CAROLINA


CONCLUSIONS

The Carolawn Site near Fort Lawn, South Carolina, is currently of indeterminate public health hazard. Although contamination of soil and groundwater exists, no documented route for human exposure exists at the current time. Although chlordane appears in a residential well, sampling of on-site monitoring wells does not definitively indicate the origin of this chlordane. No surface-soil data or indoor air monitoring data are available. The availability of this data, future development of the site, future access to the site, or the future use of contaminated groundwater could reclassify this site as a public health hazard.

Well RW-3 is currently suitable for potable use. However, future contaminant concentration trends cannot be definitely projected.

A plume of contaminated groundwater underlies one residence. Available data do not indicate that air sampling for volatile compounds within this residence has been performed.

Available data do not conclusively indicate the contamination of Fishing Creek. Samples from Fishing Creek currently show, at most, very small concentrations of site-related contaminants.


RECOMMENDATIONS
  1. Upgrade site security to preclude unauthorized entry to the site. The site contains physical hazards of industrial machinery.
  2. Establish an annual groundwater monitoring program to monitor contaminant levels in well RW-3. This program should include volatile organic compounds and pesticides.
  3. Properly abandon wells RW-1, RW-2, and RW-4 to prevent their future use for household water.
  4. Conduct additional surface soil monitoring to characterize the nature and extent of surface soil contamination. Before the site is developed, determine if contaminant levels are below health-based comparison values.
  5. Indoor air samples should be taken from residences near the site. This includes the residence southeast of the site which overlies a plume of groundwater contaminated with volatile compounds.
  6. Annually sample Fishing Creek for site-related contamination.

Health Activities Recommendation Panel (HARP) Recommendations

    The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended, requires ATSDR to perform public health actions needed at hazardous waste sites. To determine if public health actions are needed, ATSDR's Health Activities Recommendation Panel (HARP) has evaluated the data and information developed in the Carolawn Company Public Health Assessment.

    The data and information developed in the Carolawn Public Health Assessment have been evaluated by the ATSDR Health Activities Recommendation Panel (HARP) for follow-up health actions. Potential exposure pathways have been identified for nearby residents; however, currently there are no completed pathways of exposure. In coordination with other agencies, SCDHEC will provide ongoing community education to the residents near the site about possible health effects from site-related contaminants. No other follow-up health activities are indicated at this time. If information becomes available indicating exposure at levels of concern, ATSDR will evaluate that information to determine what actions, if any, are necessary.


PUBLIC HEALTH ACTIONS

To respond to community concerns, and based on the HARP recommendations, ATSDR has developed the following Public Health Action Plan:

  1. DHEC will remain available to answer any questions which the nearby residents may have about the site.
  2. EPA will periodically sample groundwater from residential wells which lie adjacent to the site. Current information indicates that one residential well is still in use and three others have not been abandoned but are not currently used for household purposes.
  3. The data gaps identified in this addendum to the Public Health Assessment, will be addressed with the upcoming Record of Decision (ROD). A ROD is a legal document that formally sets forth the remedial alternative selected for the cleanup of the NPL site. This will enable SCDHEC and ATSDR to make a complete determination of the hazard posed by the Carolawn site.
