PUBLIC HEALTH ASSESSMENT

ROUTE 561 DUMP

AND

UNITED STATES AVENUE BURN
GIBBSBORO, CAMDEN COUNTY, NEW JERSEY


CONCLUSIONS

Evaluation of Nature and Magnitude of Health Risks

A. Route 561 Dump Site

On the basis of the information reviewed, the ATSDR and NJDHSS have concluded that surface soil contamination at the Route 561 Dump site exists at levels of public health concern if young children were to gain access to contaminated areas. However, the site currently constitutes no apparent public health hazard for exposures to on-site surface soil due to a lack of completed human exposure pathways. Past exposures to contaminated soil could not be ruled out, but because it would be difficult to define a contaminant dose or identify an exposed population, no toxicological evaluation of this pathway was performed.

Under current conditions, areas of surface soils at the Route 561 Dump site are largely inaccessible to all but the most determined trespassers. This surface soil has been characterized and there are areas of heavy on-site contamination with metals, including lead, arsenic, chromium and cyanide. Some "hot spots" at the Route 561 site have been remediated.

Surface water, sediments and groundwater at the Route 561 Dump site have been shown to be adversely affected by the dumping of paint and paint sludges. It is possible that there is a widespread problem of heavy metals transport off-site via surface water, sediments and/or groundwater, therefore, these must be considered potential human exposure pathways. The potential for off-site migration of site-related contaminants through these environmental media has not been thoroughly examined.

There is at least one home near the site that uses a private well for its potable water. The well was last checked in 1994 and was found to be free of site related contamination, however, the current quality of the water is unknown. The depth of the groundwater from which this residence draws water is also unknown. The direction of groundwater flow in the area needs to be discerned.

B. United States Avenue Burn Site

On the basis of the information reviewed, the ATSDR and NJDHSS have concluded that surface soil contamination at the United States Avenue Burn site exists at levels of public health concern if young children were to trespass at the site. However, the site currently constitutes no apparent public health hazard for exposures to on-site surface soil due to a lack of a completed human exposure pathway. It is important to note, however, that it was concluded that there were completed exposure pathways at the United States Avenue Burn site in the past. The United States Avenue Burn site represented a public health hazard in the past, based on available information and an analysis of exposure dose and duration. Adults utilizing the site were not likely to have been exposed to lead contamination at concentrations sufficient to constitute a public health hazard. Children, however, may have been exposed to levels of lead that may pose a public health hazard.

Under current conditions, areas of surface soils at the United States Avenue Burn site are largely inaccessible to all but the most determined trespassers. Surface soil has been extensively characterized and there are areas of heavy contamination with metals, including lead, arsenic, and chromium.

Some "hot spots" at the Railroad Track Area sub-site of the United States Avenue Burn site have undergone a removal action. Contaminated "hot spots" have been excavated and these areas were capped and covered with clean soil. The contaminated surface soil at the United States Avenue Burn site (landfill and burn areas) have not been remediated to date.

Surface water, sediments and groundwater at the United States Avenue Burn site have been shown to be adversely affected by the dumping of paint and paint sludges, which has lead to contamination of media with heavy metals and possibly benzene. In addition, some of the contamination at the United States Avenue Burn site may be related to former landfilling activities. It is possible that there is a widespread problem of heavy metals transport off-site via surface water, sediments and/or groundwater. Therefore, these must be considered potential human exposure pathways. The potential for off-site migration of site related contaminants through these environmental media has not been thoroughly examined.

As with the Route 561 Dump site, there is at least one home near the site that uses a private well for its potable water. The well was last checked in 1994 and was found to be free of site related contamination, however, the current quality of the water is unknown. The depth of the groundwater from which this residence draws water is also unknown. The direction of groundwater flow in the area needs to be discerned.


RECOMMENDATIONS

A. Cease/Reduce Exposure

  1. Inform the public about the Route 561 Dump site and United States Avenue Burn site and the potential hazards of each because it would be prudent to keep trespassers off the sites. The fences surrounding the two sites need to be periodically checked to keep them secure against trespassers.


  2. Identify and sample all private well water potentially impacted by the sites.


  3. Monitor nearby surface water features (creeks and lakes) periodically to determine if off-site migration of contamination has or is occurring.


  4. Utilize optimal dust control measures during site remediation due to the nature and extent of soil contamination.

B. Site Characterization

The following information is needed to fully and adequately evaluate the public health impact of the Route 561 Dump site and the United States Avenue Burn site:

  1. Conduct hydrogeologic investigations of area groundwater to characterize the direction and extent of contaminant migration from the site.

PUBLIC HEALTH ACTIONS

The Public Health Action Plan (PHAP) for the Route 561 Dump site and United States Avenue Burn site contains a description of the actions to be taken by ATSDR and/or NJDHSS at or in the vicinity of the sites subsequent to the completion of this Public Health Assessment. The purpose of the PHAP is to ensure that this health assessment not only identifies public health hazards, but provides a plan of action designed to mitigate and prevent adverse human health effects resulting from exposure to hazardous substances in the environment. Included is a commitment on the part of ATSDR/NJDHSS to follow up on this plan to ensure that it is implemented. The public health actions undertaken or planned by ATSDR/NJDHSS are as follows:

A. Public Health Actions Taken

  1. Environmental data have been evaluated within the context of human exposure pathways and relevant public health issues.


  2. The ATSDR/NJDHSS prepared a fact sheet concerning the two sites (January 1998). A draft of this document was distributed to the Camden County Health Department (CCHD). The CCHD was also contacted by letter (January 1998 and April 1998) to determine if they required any assistance. The CCHD did not indicate a need for our direct assistance.

B. Public Health Actions Planned

  1. ATSDR and the NJDHSS will coordinate with the appropriate environmental agencies to develop plans to implement the cease/reduce exposure and site characterization recommendations contained in this health assessment.


  2. The ATSDR/NJDHSS will review data generated during the remedial investigations or other environmental investigations at these sites and, if necessary, evaluate these data for public health significance.


  3. The ATSDR/NJDHSS will contact the CCHD and again offer our assistance in addressing community needs. The NJDHSS/ATSDR will also provide a Citizen's Guide to this document to the CCHD, local libraries, and interested parties.


  4. This report will be placed in repositories that contain copies of this health assessment, and will be provided to persons who request it.


  5. The ATSDR and the NJDHSS will reevaluate and expand the Public Health Action Plan (PHAP) as warranted. New environmental, toxicological, or health outcome data, or the results of implementing the above proposed actions, may determine the need for additional actions at these sites.
