PETITIONED PUBLIC HEALTH ASSESSMENT

CALDWELL SYSTEMS INCORPORATED
LENOIR, CALDWELL COUNTY, NORTH CAROLINA


CONCLUSIONS

From the information reviewed, ATSDR has concluded that the environmental contamination that was previously released from the Caldwell Systems Incorporated site was a public health hazard. That conclusion was reached as a result of evidence that workers, their families, and nearby communities were in the past exposed to site contaminants.

The facility no longer operates; therefore, no further exposures are expected, and the facility is considered to be of no apparent public health hazard.

The extent of the groundwater contamination has not been fully defined; however, it does not appear that the existing level is of public health concern.

Environmental contamination associated with the Caldwell County Landfill is not addressed in this public health assessment.


RECOMMENDATIONS

A. Recommendations and Health Activities (HARP) Statement

ATSDR recommends the following actions be taken at the Caldwell Systems Incorporated petition site:

  1. ATSDR will evaluate the Caldwell County Landfill as public health needs dictate and as resources permit.
  2. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, requires ATSDR to perform public health actions needed at hazardous wastes sites. To determine if additional public health actions are needed, ATSDR's Health Activities Recommendation Panel (HARP) has evaluated the data and information developed in the public health assessment of the Caldwell Systems site. The information available indicates that there were probable past exposures to levels of contamination that would be expected to cause adverse health effects. ATSDR has conducted a Symptom-Disease Prevalence Study and Professional Health Education at this site.

B. Public Health Action Plan

The Public Health Action Plan (PHAP) for the CSI petition site includes a description of the actions that have been taken by ATSDR at and in the vicinity of the site. 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 to ensure the protection of public health. The following are the public health actions that have been implemented by ATSDR:

Actions Undertaken

  1. The Division of Health Assessment and Consultation released a health consultation in May, 1990.
  2. ATSDR issued a public health advisory on July 24, 1990.
  3. The Division of Health Education provided environmental health education to local health care providers in 1990.
  4. The Division of Health Studies conducted a study of area residents and family members of former employees in 1991.
  5. The National Institute for Occupational Safety and Health examined the health of former CSI employees in 1990 and 1991.
  6. The Study of Symptom and Disease Prevalence conducted by ATSDR's Division of Health Studies also conducted respiratory, immune, and neurologic functions among persons living within 0.9 mile of the incinerator be evaluated using biomarker testing.

Actions Planned

  1. ATSDR will continue evaluate the Caldwell County landfill as public health needs dictate and as resources permit.
