PUBLIC HEALTH ASSESSMENT

GEIGER (C & M OIL) SITE
RANTOWLES, CHARLESTON COUNTY, SOUTH CAROLINA

CONCLUSIONS

The Geiger site is classified as an indeterminate public health hazard because of insufficient surface soil data, fish sampling data, or groundwater data. The limited data do not indicate that humans are being exposed to contaminants that would have an adverse health impact. If additional data becomes available, this classification may change.

A future potential exposure pathway was identified for the Geiger site. The primary method of this potential exposure is through dermal contact with low levels of on-site contaminants, or inadvertent on-site soil ingestion. The future exposure to on-site soil is considered minimal as the area would have to be further developed for this possibility to become viable.

The public was concerned about the effects of drinking the water from their private wells. The private wells were tested and there were no contaminants found to exceed the comparison values. We do not believe drinking the water is a realistic concern due to the inherent odor, color, and taste problems that occur with petroleum products in water. The public has taken active participation in learning about the site and have been participating in public meetings.

RECOMMENDATIONS

  1. We recommend that the environmental fate and transport of site-related contaminants be fully characterized.
  2. On-site workers should minimize contact with contaminated soil.
  3. We recommend periodic sampling of the private wells near the site. Although the private wells are hydraulically up-gradient, it would be prudent to rule out the possibility of contamination in drinking water wells.
  4. Recommend that all possible sources of contamination in the area unrelated to the site be identified. Further investigation is recommended to determine the source of downgradient, off-site, groundwater contamination.
  5. Conduct water and fish sampling from the on-site fishing pond to determine whether contamination exists, what contaminants are present, and their potential health effects to people who consume fish from this pond. We also recommend that signs be posted around the ponds advising people not to fish in this pond.
  6. Conduct on-site and off-site surface soil samples from the top three inches of soil.
  7. Recommend that the existing fence around the site be repaired and extended around the unfenced areas so that the site will be completely secured. The partial fence in the southern portion of the site does not extend to the natural boundary of the trees in the southwestern border of the site. The western border of the site is surrounded by trees, but no fence exists in this area allowing easy access to the site.
  8. Recommend the collection and analysis surface water and sediment samples from the areas adjacent to the on-site ponds.
  9. In accordance with CERCLA, as amended, the data and information contained in the Geiger Site (C & M Oil) Public Health Assessment have been evaluated by the ATSDR Health Activities Recommendation Panel for appropriate follow-up with respect to health actions. An on-site pond used for fishing may contain contaminated water and fish. A completed exposure pathway would exist if sampling determines contaminants in fish from this pond. A public availability session will be conducted to inform on-site workers and local residents that on-site ponds should not be used for fishing purposes. If information becomes available indicating exposure at levels of concern, SCDHEC and ATSDR will evaluate that information to determine what actions, if any, are necessary.

PUBLIC HEALTH ACTIONS

The following Public Health Action Plan (PHAP) for the Geiger (C & M Oil) site contains a description of actions to be taken by ATSDR and/or SCDHEC at and in the vicinity of this site subsequent to the completion of this public health assessment. The purpose of the PHAP is to ensure that this public health assessment not only identifies public health hazards, but provides a plan of action designed to mitigate and prevent adverse health effects resulting from exposure to hazardous substances in the environment. Included in this plan is a commitment on the part of ATSDR/SCDHEC to follow up on this plan to ensure that it is implemented. The public health actions to be implemented by ATSDR and/or SCDHEC are as follows:

  1. SCDHEC will remain available to answer any questions that the community may have pertaining to the site.
  2. SCDHEC, in cooperation with ATSDR, will hold a public availability session to inform on-site workers and local residents not to use on-site ponds for fishing purposes. SCDHEC will recommend that warning signs be posted around on-site ponds discouraging any fishing activities.
  3. SCDHEC, in cooperation with ATSDR, will review and evaluate additional sampling data as it becomes available to determine if further actions are needed.
  4. SCDHEC will recommend continued sampling of water from residential drinking wells downgradient from the site.

In addition, the U.S. Environmental Protection Agency has committed to the following actions:

  1. EPA will ensure that contaminated groundwater is recovered and remediated.
  2. EPA will ensure that contaminated soil is solidified and stabilized on-site.

ATSDR and SCDHEC will follow-up with the EPA and other agencies to confirm implementation of the other recommendations contained in this public health assessment.
