PUBLIC HEALTH ASSESSMENT

GENZALE PLATING COMPANY
FRANKLIN SQUARE, NASSAU COUNTY, NEW YORK


CONCLUSIONS

Based on the information reviewed, this site poses an indeterminate public health hazard. The available data do not indicate that humans are being or have been exposed to levels of contamination that would be expected to cause adverse health effects. However, data or information are not available for all environmental media to which humans may be exposed. Surface soils have not been sampled in residential yards next to the Genzale Plating Company site. There are insufficient or no community-specific health outcome data to indicate that the site has had an adverse effect on human health.

At this time, ingestion of contaminated drinking water is not occurring. Two downgradient public supply wells providing water to residents in the area of the Genzale Plating site had been contaminated with low levels of VOCs. The low levels of VOCs in the downgradient wells may have originated from the Genzale Plating Site and other sources.

Groundwater is contaminated off-site and in a private irrigation well. Limited data are available to monitor an off-site groundwater plume which is believed to be responsible for the contamination of the irrigation well.

Near surface soils and subsurface soils are contaminated at the site, but off-site soil was not sampled. Elevated levels of metals were found in near surface soils. There is a need to prevent human exposure, if occurring, to these soilborne contaminants.

Neighboring residents and remedial workers have an increased risk of exposure to contaminants through inhalation of soil or particulates, ingestion, and dermal contact during site remedial activities in which soils are likely to be excavated.

RECOMMENDATIONS

  1. Continue to monitor public drinking water supply wells near the Genzale Plating Company, especially those public wells located downgradient of the site. This monitoring is currently mandated by the State of New York, and if contaminants are detected above drinking water standards, treatment will be provided or other municipal water supplies will be utilized. The off-site downgradient monitoring well (MW-4S) should also be routinely monitored to evaluate the movement of the groundwater plume that is associated with the site.
  2. Install additional monitoring wells off-site and downgradient from the site to further evaluate a groundwater plume which may be associated with the site.
  3. Sample surface soils in residential yards adjoining the Genzale Plating Company site.
  4. Control dust and conduct perimeter air monitoring should be done during remedial activities to detect any airborne contaminants leaving the site.
  5. Notify residents near the site of site remediation schedules and activities.

HEALTH ACTIVITIES RECOMMENDATION PANEL

The data and information in the Public Health Assessment for the Genzale Plating site, Franklin Square, New York, has been evaluated by the ATSDR's Health Activities Recommendation Panel for appropriate follow-up with respect to health activities. Although exposure to contaminated drinking water may have occurred in the past, this site is not being considered for follow-up health activities at this time because the contaminants were not present at levels of public health concern. However, if data or information become available suggesting that human exposure to hazardous substances at levels of public health concern is currently occurring or has occurred in the past, the ATSDR will reevaluate this site for any indicated follow-up health actions.

PUBLIC HEALTH ACTIONS

The Public Health Action Plan (PHAP) for the Genzale Plating Company site contains a description of actions to be taken by the ATSDR, US EPA and/or the NYS DOH at and near 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 on the part of the ATSDR/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. Active public drinking water supply wells near the Genzale Plating Company site have been and continue to be tested by the NC DOH at the specified intervals as mandated by the NYS DOH.
  2. The Remedial Design workplan prepared for the US EPA by Ebasco Services, Inc. details additional sampling of all on-site and off-site monitoring wells.
  3. The RI/FS second operable unit workplan addendum details plans for additional monitoring wells downgradient of the site to further define the groundwater contamination plume.
  4. The Remedial Design workplan details plans for additional sampling of surface soils in residential yards adjoining the Genzale site.
  5. Persons exposed in the past to volatile organic compounds in their drinking water will be considered for inclusion in the VOC Registry which is being developed by the NYS DOH.
  6. All site activity will be conducted under a prepared Health and Safety Plan. These plans will contain provisions for air monitoring to assure that concentrations of on-site contaminants do not exceed action levels at or beyond the perimeter of the site.

The ATSDR will re-evaluate and expand the PHAP 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 Genzale Plating Company site was prepared by the New York State Department of Public 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.
