PUBLIC HEALTH ASSESSMENT

A. O. POLYMER
SPARTA TOWNSHIP, SUSSEX COUNTY, NEW JERSEY


CONCLUSIONS

  1. Based on current site data and information, the NJDOH and the ATSDR consider the A.O. Polymer site to pose a no apparent public health hazard as on-going removal actions have secured and stabilized the site.
  2. The A.O. Polymer site posed a public health hazard because past exposure to contaminanted drinking water may result in adverse health effects. Public water supplies have been made available to residents since 1980. The lifetime excess cancer risk (LECR) associated with the chronic oral exposure route for formaldehyde at the site for a duration of 20 years would present a low increased risk of cancer. Past exposure to TCE is not expected to cause adverse chronic health effects via the oral route of exposure because estimated exposure doses were below the NOAEL for non cancer effects. The lifetime excess cancer risk (LECR) associated with the chronic oral exposure route for trichloroethylene at the site for a duration of 20 years would present insignificant or no increased risk of cancer.
  3. Access to the A.O. Polymer site is unrestricted. However, numerous removal actions and securing the buildings on-site has minimized the physical hazards that previously existed.
  4. The potential for odors to emanate from the buildings no longer exists as plant operations has ceased on site and hazardous materials have been removed from the buildings.
  5. Using a mathematical model, air concentrations were calculated based on the volatilization of chemicals from the groundwater plume. This did not take into account the release of odors from poor manufacturing practices or from the volatilization of contaminants from the buildings themselves. Direct air sampling on-site and off-site were not conducted in the past during plant operation. There are insufficient data to evaluate the air pathway at the site.
  6. The bedrock aquifer may become contaminated by the shallow overlying aquifer, resulting in potential risk to the population using the bedrock aquifer for drinking water.

RECOMMENDATIONS

  1. Periodically monitoring of the bedrock aquifer should continue until groundwater treatment system is installed and operating as specified in the ROD.

New environmental, toxicological, health outcome data, or changes in conditions as a result of implementing the proposed remedial plan, may determine the need for other additional actions at this site.

HEALTH ACTIVITIES RECOMMENDATION PANEL (HARP)

The data and information developed in the public health assessment for the A.O. Polymer site, Sparta Township, New Jersey have been evaluated by ATSDR's Health Activities Recommendation Panel (HARP) for appropriate follow up with respect to health activities. The panel determined that no follow up actions are indicated at this time. Furthermore, the HARP concurs with the community health education performed in the past by the USEPA. If additional data or information become available, ATSDR will revaluate this site for any indicated follow up health action.

PUBLIC HEALTH ACTIONS

The Public Health Action Plan (PHAP) for the A.O. Polymer site contains a description of actions to be taken by the NJDOH and/or the ATSDR at the 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 human health effects resulting from exposure to hazardous substances in the environment. Included is a commitment by the NJDOH and the ATSDR to follow-up on this plan to ensure that it is implemented.

A. Public Health Actions Taken

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

B. Public Health Actions Planned

  1. The Township of Sparta Health Department will follow-up to make certain that any potential exposures/risks to trespassers on the site are minimized.
  2. ATSDR and the NJDOH will coordinate with the appropriate environmental agencies to develop plans to implement the site characterization recommendation contained in this health assessment.
  3. ATSDR will provide an annual follow-up to this PHAP, outlining the actions completed and those in progress. This report will be placed in repositories that contain copies of this health assessment, and will be provided to persons who request it.
  4. ATSDR will reevaluate and expand the Public Health Action Plan (PHAP) when needed. New environmental, toxicological, health outcome data, or the results of implementing the above proposed actions may determine the need for additional actions at this site.

CERTIFICATION

The Public Health Assessment for the A.O. Polymer site was prepared by the New Jersey Department of Health under a cooperative agreement with the Agency for Toxic Substances and Disease Registry (ATSDR). It is in accordance with approved methodology and procedures existing at the time the public health assessment was initiated.
