PUBLIC HEALTH ASSESSMENT

PASLEY SOLVENTS & CHEMICALS INC.
GARDEN CITY, NASSAU COUNTY, NEW YORK


CONCLUSIONS

This site poses an indeterminate public health hazard as there arevery limited ambient air data and recent soil gas data toadequately assess the human exposure pathways involving thesemedia.

A public health hazard existed in the past because persons may havebeen exposed to levels of VOC contaminants in their drinking waterthat upon long term exposure could result in a low increased riskof developing cancer. However, the Pasley site is not believed tobe the source of public water supply contamination. There are nocommunity specific health outcome data to indicate that the site orthe past exposures (probably not site-related) has had an adverseimpact on human health.

At the present time, ingestion of contaminated drinking water(contaminated above State drinking water standards) is notoccurring. However, volatile organic compounds have been detectedin six public drinking water supply wells located less than onemile downgradient from the Pasley site. Two of these six wellshave been provided with treatments due to VOC contamination atlevels above NYS DOH drinking water standards. The low level ofVOC contamination detected in the remaining wells would be expectedto be further reduced through distribution controls.

Air and soil gas (intrusion) exposure pathways cannot be adequatelycharacterized because recent measurements have not been taken forthese media at nearby occupied buildings.


RECOMMENDATIONS

  1. Groundwater quality needs to be monitored downgradient from the site and in the general path of groundwater flow.
  2. Public drinking water supply wells located downgradient from the Pasley site should continue to be monitored at frequent intervals to ensure that they are not being impacted by site related contaminants. This monitoring is currently mandated by the State of New York. Should these wells become contaminated above drinking water standards, other municipal water supplies and/or treatment should immediately be provided.
  3. Additional investigation is needed to assess the upgradient groundwater contamination problem. This recommendation is based on the fact that regardless of the Pasley site cleanup, upgradient sources will continue to be a source of contamination to the groundwater beneath the site. A site of particular concern is the nearby Roosevelt Field site. It is likely that a contaminant plume has expanded from the Roosevelt Field site and intercepted the Pasley site area. In 1991, the Roosevelt Field site was added to New York State's Registry of Inactive Hazardous Waste Disposal sites.
  4. The integrity of the fencing around the site should be monitored to prevent present and future access to the site.
  5. The safety of on-site remedial workers and the surrounding community should be addressed during activities which may disturb the existing contaminated soils. Optimal dust control measures should be used and perimeter monitoring (for presence and transport of soil vapor) should be implemented during the remedial activities to ensure the safety of all nearby residents. Appropriate protective clothing and respiratory protection should be worn by workers during activities involving disturbance of soils at the site. On-site remedial workers should follow appropriate National Institute for Occupational Safety and Health and Occupational Safety and Health Administration guidelines and recommendations.
  6. The potential for site-related contaminants to impact indoorair quality at nearby buildings warrants the need to take soilgas measurements near the foundations of active facilities andresidences. These data could be used to determine the need toconduct indoor air sampling.

HEALTH ACTIVITIES RECOMMENDATION PANEL (HARP) RECOMMENDATIONS

The data and information developed in the public health assessmentfor the Pasley Solvents and Chemicals, Inc., Garden City, New York,has been reviewed by ATSDR's Health Activities RecommendationsPanel (HARP) to determine appropriate follow-up actions. Becauseof past exposure to contaminated drinking water (probably not site-related) and community health concerns, the panel recommendedfollow-up health activities. Specifically, those persons exposedin the past (probably not site-related) should be considered forinclusion on NYSDOH's registry being developed for VOC exposuresfrom drinking contaminated water. The NYSDOH registry will bematched with the cancer registry to evaluate possible adversehealth outcomes. The HARP also determined that community healtheducation is needed. The Nassau County Department of Health,however, has educated the community regarding the generalgroundwater contamination problem in the area. No site-relatedfollow-up activities were recommended by HARP at this time.


PUBLIC HEALTH ACTIONS

The Public Health Action Plan (PHAP) for the Pasley site containsa description of actions to be taken by the US EPA, ATSDR, and/orthe New York State Department of Health (NYS DOH) at and near thesite subsequent to the completion of this public health assessment. For those actions already taken at the site, please see theBackground section of this public health assessment. The purposeof the PHAP is to ensure that this public health assessment notonly identifies public health hazards, but provides a plan ofaction designed to mitigate and prevent adverse human healtheffects resulting from exposure to hazardous substances in theenvironment. Included, is a commitment on the part of ATSDR/NYSDOH to follow up on this plan to ensure that it is implemented. The public health actions to be implemented are as follows:

  1. The ATSDR will consider adding persons exposed to trichloroethene through use of their domestic water supplies to the trichloroethene subregistry if the analysis of the data on the current registrants should indicate a need for additional members.
  2. Persons exposed in the past to VOCs through use of their domestic water supplies will be considered for inclusion on NYS DOH's registry being developed for VOC exposures from contaminated drinking water.
  3. The NYS DOH and US EPA will ensure that appropriate measures are taken during remediation activities to minimize potential exposures to site contaminants for residents living/working near the site.
  4. The ATSDR and NYS DOH will coordinate with the appropriate agencies about those recommendations for which no plan of action has yet been developed.
  5. The NYS DOH will reevaluate 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.
  6. The NYS DOH will perform an evaluation of public health issuesrelated to the Roosevelt Field site.
