PUBLIC HEALTH ASSESSMENT

PREFERRED PLATING CORPORATION
EAST FARMINGDALE, SUFFOLK COUNTY, NEW YORK


CONCLUSIONS

Based on the information reviewed, the site presented a public health hazard in the past because of chromium in non-residential private wells. However, these wells have been abandoned and public water now supplies the affected properties. Currently the site presents no apparent public health hazard as long as the planned remedial measures are taken. There are no known human exposures to contaminants at levels of concern for human health. Subsurface soil underneath the building on-site is contaminated with volatile organic compounds and metals and groundwater on-site is contaminated with metals. The subsurface soil serves as a continuing source of contamination to the groundwater. However, planned remedial measures should prevent this contamination from resulting in long-term exposures.

Shallow soil on-site is contaminated with cadmium and chromium at concentrations in excess of comparison values. Subsurface soil on-site contains cadmium and chromium at concentrations in excess of comparison values. However, because the site is paved, no human exposure to contaminated soil is possible.

Subsurface soil underneath the building in and near the former waste leaching pits are contaminated with volatile organic compounds, cadmium, and chromium. The contamination under the building is not available for human contact under existing conditions. If site use changes and the building is removed, the soil may be made available for human contact. In addition, this contaminated soil may continue to contribute contamination to the groundwater.

On-site groundwater is contaminated with cadmium, chromium, lead, and several volatile organic compounds in excess of drinking water standards. The US EPA has chosen to remediate the groundwater and a treatment system is planned. This ground-water treatment will reduce on-site groundwater contamination to concentrations below drinking water standards.

The Preferred Plating Corporation site was the documented source of chromium contamination which was detected in off-site groundwater between 1953 and 1958. The site may be contributing to the groundwater contamination which was detected in 1991 and 1993, however, other sources may also be contributing to this contamination. Public drinking water supply wells that are in the direction of groundwater flow from the site have not been contaminated. The groundwater treatment system will minimize off-site movement of the contamination which is present on-site.

One private well downgradient of the site is being used and contains water which is contaminated with low levels of metals and volatile organic compounds.

No site-specific health outcome data bases have been generated for this site. However, a study of breast cancer incidence rates in Nassau County and Suffolk County in 1990 and a study of Hodgkin's disease incidence in the Massapequa/Farmingdale area of Nassau and Suffolk Counties in 1991 showed no association with hazardous waste sites, including Preferred Plating. Because of continued concerns of residents in the Massapequa/Farmingdale area, this study will be redone to include the years 1980-1989.

Although no specific public comments have been received about the site, the SC DHS has expressed concern about contamination of the groundwater resource. SC DHS concerns about on-site contamination will be addressed by the proposed remedial measures. On-site groundwater contamination will be remediated by groundwater pumping and treating.


RECOMMENDATIONS

  1. Subsurface soil contamination underneath the building should be addressed. The soil should be remediated to prevent future human exposures from occurring should site use change.
  2. On-site groundwater contamination should be addressed.
  3. The private well downgradient of the site should be monitored periodically or be properly abandoned. If abandoned, the commercial building served by the well needs to be hooked up to public water.

HEALTH ACTIVITIES RECOMMENDATION PANEL (HARP) RECOMMENDATIONS

The data and information evaluated for the public health assessment for the Preferred Plating, Farmington, Suffolk County, New York, have been reviewed by ATSDR's Health Activities Recommendation Panel for appropriate follow-up with respect to health activities. Although past exposure to VOC's and chromium have occurred in the past, and may be occurring currently, this site is not being considered for follow-up health actions. The location of persons who were exposed in the past, at levels that may result in adverse health effects, is not known. The panel determined that the community health education performed by the NYS DOH was appropriate.


PUBLIC HEALTH ACTIONS

The Public Health Action Plan for the Preferred Plating Corporation site contains a description of actions to be taken by US EPA and/or the NYS DOH and SC DHS at and near the site, following 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 past, present and/or future exposures to hazardous substances at or near the site. Included, is a commitment on the part of the NYS DOH to follow up on this plan to ensure that it is implemented. The public health actions to be implemented are as follows:

  1. US EPA will implement the Record of Decision for excavating and off-site treatment and disposal of contaminated soil.
  2. US EPA will implement the Record of Decision for the groundwater pumping and treating system to remediate the groundwater contamination at the Preferred Plating site.
  3. The NYS DOH, SC DHS and US EPA will coordinate appropriate actions for the private well which is downgradient of the site. This will include either hooking the commercial building up to public water and abandoning the well, or periodically monitoring the well. If, in the future, other private wells are found in the potentially affected area downgradient of the site, the water will be sampled and similar appropriate action will be taken.
  4. The NYS DOH and the ATSDR will contact the U.S. Army to determine if the persons exposed in the past can be located, and will provide them with a copy of this public health assessment.
  5. ATSDR will provide an annual follow-up to the Public Health Action Plan, outlining the actions completed and those in progress. This report will be placed in repositories that contain copies of this Public Health Assessment, and will be provided to persons who request it.
  6. ATSDR will reevaluate and expand the Public Health Action Plan when 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 this site.

CERTIFICATION

The Public Health Assessment for the Preferred Plating Corporation site was prepared by the New York State 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.
