OLD BRIDGE, MIDDLESEX COUNTY, NEW JERSEY
Based on the available information, ATSDR concludes that the Global Landfill NPL site is an indeterminate public health hazard because most of the on- and off-site data are not appropriate for determining possible health impacts for the site. Adverse health effects are unlikely for the specific locations which sampling was done. The on-site environmental sampling is adequate for characterizing the extent of environmental contamination at Global Landfill.
It is possible that airborne contaminants have or are migrating into the nearby residential areas. The air dispersion modelling done does not adequately evaluate this potential exposure pathway. Air monitoring at the landfill and in the residential areas should be done to determine whether significant human exposure is occurring. Additional environmental sampling should include systematic sampling of off- surface-soil (0-3 inches), and aquatic biota sampling.
The results of the community soil monitoring program indicate that the residential areas immediately around the landfill were not built on a landfill. The results further indicate that there are no sources of organic vapors in the soil of this residential area.
NJDEPE is planning to place a modified hazardous waste cap on the landfill, install a berm at the toe of the landfill slope, actively collect and treat the landfill gas, collect and treat the leachate, fence the site, conduct storm-water management, and conduct soil erosion control measures (operable unit 1). When those corrective actions are completed, the potential for human exposure to Global Landfill site-related contaminants should be reduced, provided operable unit 1 is appropriately designed and maintained.
The results of the pediatric health examination was that the vast majority of the physical exams and laboratory exams were within normal parameters, and there was no association with proximity to the site for those that were not. Once controlled for confounding factors such as age and living with smokers, the only reported symptom associated with proximity to the landfill was pounding headaches. This association was only for play areas, not for residence. The results of those pediatric examinations was probably affected by several factors including a strong selection bias.
The analysis of those cancer types indicates that the incidence of all the cancer types evaluated combined was significantly lower than that what was expected from state incidence rates. The incidence rates for each of the cancer types evaluated and by sex were not significantly different from those expected from state rates. These results indicate that the incidence of cancer in the area around Global Landfill is not as excessive as believed by some residents.
The five human health outcomes for which comparisons could be made - allergies, asthma, bronchitis, diabetes, and heart murmurs - were not statistically elevated. Appropriate comparison populations could not be identified for the other reported health outcomes - miscarriages, rashes, thyroid problems, and several types of cancer. ATSDR is not able to evaluate those human health outcomes.
ATSDR recommends the following for this site:
|1)||Systematic sampling of off-site surface soil (0-3 inches), ambient air, and aquatic biota should be conducted by an appropriate state or federal agency to identify possible exposures to site-related contaminants.|
|2)||NJDEPE should ensure workers conducting remedial activities use adequate personal protective equipment that meets Occupational Safety and Health Administration (OSHA) standards and National Institute of Occupational Safety and Health (NIOSH) recommendations.|
|3)||If evidence of human exposure becomes available, the evaluation of additional relevant health outcome data, especially birth defects data, should be considered.|
The data and information developed in the public health assessment for Global Landfill NPL site, which is in Old Bridge, Middlesex County, New Jersey, has been evaluated by the ATSDR Health Activities Recommendation Panel (HARP). Available data are inadequate to determine whether human exposure has occurred or is occurring off-site. Because of widespread community concern, the Task Group on Global Landfill and Sommers Brothers Property Sites was formed by the New Jersey legislature. The Task Group includes citizens, and state and local agencies. One of its roles is to identify and implement community-based environmental health education. In cooperation with ATSDR, the Task Group is considering site-specific educational programs for health professionals.
