PUBLIC HEALTH ASSESSMENT

TABERNACLE DRUM DUMP
TABERNACLE TOWNSHIP, BURLINGTON COUNTY, NEW JERSEY


CONCLUSIONS AND RECOMMENDATIONS

Conclusion:

This site is of potential health concern because of the risk to human health resulting from possible exposure to hazardous substances at concentrations that may result in adverse health effects. As noted in Section C above, human exposure to lead is occurring via ingestion of contaminated groundwater. Human exposure to TCA may occur in the future.

The on-site groundwater is currently contaminated with chromium, lead, DCE, and TCA. The potential for future TCA contamination of nearby residential wells is high and represents a route of human exposure through ingestion, inhalation and dermal absorption. The ingestion of lead now occurring from some residential wells may be site-related. The site soils are contaminated with levels of cyanide, lead, and chromium which currently do not pose a health concern of and by itself but may aggravate the total lead and chromium exposure caused by the groundwater.

Recommendations:

1. Continued monitoring of residential wells is recommended. The TCA contamination plume was projected to reach the nearest residential well in 14 years. Although the level of TCA contamination is not expected to be as high as on-site concentrations because of dilution, this possibility cannot be discounted. The metals concentrations, especially lead, should be monitored closely to determine if further increases occur. Further groundwater sampling may be required to determine the sources of lead and chromium contamination.

2. Since the site is near a residential area, we recommend that the site access be restricted so that further exposure to lead and chromium is minimized.

3. Real time air monitoring should be conducted during remedial activities on-site and at the worksite periphery. Remedial workers should be provided with adequate personal protective equipment as required by the Occupational Safety and Health Administration (OSHA).

4. Implement institutional controls to prevent the installation of new water supply wells within the contaminated portion of the aquifer.

In accordance with CERCLA as amended, the Tabernacle Drum Dump NPL Site in Burlington County, New Jersey has been evaluated for appropriate follow-up with respect to health effects studies. Although there are indications that human exposure to off-site contaminants has and may be occurring, this site is not being considered for follow-up health studies at this time because the available residential well sampling data do not indicate significant contamination. When additional residential well data is available for ATSDR review, the need for additional studies will be considered.
