PUBLIC HEALTH ASSESSMENT

SIDNEY LANDFILL
SIDNEY, DELAWARE COUNTY, NEW YORK


CONCLUSIONS

Based on ATSDR's current Public Health Hazard Category classification (Appendix D), the Sidney Landfill site was a public health hazard in the past. In the past, nearby residents drank water containing vinyl chloride, trichloroethene and tetrachloroethene at levels that could pose a low to moderate increased cancer risk. Currently, however, these exposures have been reduced or eliminated by treatment systems on the residents' water supplies which remove VOCs or, for one resident, by replacement of the contaminated well with an uncontaminated well. On-site workers and trespassers were likely exposed to PCBs, arsenic and lead in surficial soil and vinyl chloride and PCBs in on-site leachate seeps at levels that could increase the risk of adverse health effects upon chronic exposure. The site is currently posted and there is little evidence of use; however, it is not fenced. Remedial measures which are underway, which include consolidating and covering wastes, will eliminate this potential exposure pathway in the future. Therefore, the Sidney Landfill site is no apparent public health concern as long as the planned remedial measures are completed.

The 1990 preliminary health assessment concluded that exposures to volatile organic compounds may be occurring by groundwater use, and that exposure to PCBs may be occurring by direct contact with contaminated soil. It recommended that the RI be completed, to determine the extent of contamination. The conclusions made in the 1990 preliminary health assessment were valid and the recommendations were followed. Surface water was sampled, affected water supplies are being treated and the RI has been completed which defines the nature and extent of contamination. No further assessment is warranted at this time. Additionally, the US EPA has developed a plan for remediating the site, which began in 1998. This will eliminate the potential for people to be exposed to contaminants by direct contact.


RECOMMENDATIONS

  1. The ROD, consisting of consolidating contaminated soil and wastes and capping the landfill, should be implemented to ensure that direct contact with contaminated soil does not occur.

  2. The US EPA should continue to ensure that the responsible party monitors private water supplies and that the treatment systems continue to be maintained until contaminants are consistently below NYS DOH drinking water standards.

  3. Appropriate land use restrictions should be made so that people are not exposed to site contaminants in the future.

  4. The remedial program for the nearby Richardson Hill Road Landfill should include measures to mitigate potential exposure to PCBs in South Pond.

  5. Groundwater, leachate and surface water should be monitored, as necessary, to determine if the remediation is effective in addressing possible off-site impacts from the landfill.

The data and information developed in the Public Health Assessment for the Sidney Landfill site in Delaware County, New York, have been evaluated to determine whether follow-up actions may be indicated. No further public health actions are indicated at this time.


PUBLIC HEALTH ACTION PLAN

The Public Health Action Plan (PHAP) for the Sidney Landfill site describes the actions to be taken by ATSDR and/or the NYS DOH following completion of this Public Health Assessment. Those actions already taken at the site are included in the Background and Statement of Issue sections 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 present and/or future exposures to hazardous substances at or near the site. ATSDR and/or the NYS DOH will ensure that this plan is implemented. The public health actions for the Sidney Landfill site are as follows:

  1. ATSDR and the NYS DOH will coordinate with the appropriate environmental agencies to implement the recommendations in this Public Health Assessment.

  2. ATSDR will provide follow-up to this PHAP as necessary, outlining the actions completed and those in progress. The follow-up report will be placed in repositories that contain copies of this Public Health Assessment, and will be provided to persons who request it.

  3. The NYS DOH will continue to conduct community health education as appropriate.

  4. Residents who were exposed to VOCs in their drinking water will be considered for inclusion to the VOC registry which is being developed by the NYS DOH.

ATSDR will reevaluate and expand the PHAP as needed. New environmental, toxicological, or health outcome data, or the results of implementing the above proposed actions may determine the need for additional actions at the site.
