Response to Public Questions and Concerns
Preferred Plating
This summary was prepared to answer questions and concerns from the public on the Preferred Plating draft Public Health Assessment. The public was invited to review the draft Public Health Assessment through a mailing to the site's contact list. The public review period was from March 31 to May 3, 1993 and responses were received by the New York State Department of Health. Similar comments may have been grouped together, and some comments may have been consolidated to incorporate several similar concerns raised by more than one person. We thank the staff of the Suffolk County Department of Health Services (SC DHS) for comments on the draft Public Health Assessment. The document has been revised based on their comments. If you have any questions, please contact Ms. Nina Knapp of the Health Liaison Program at the toll-free number 1-800-458-1158, extension 402.
COMMENT #1
Was an investigation conducted to determine if those individuals with Hodgkin's Disease had an increased exposure of benzene in the workplace or at home?
RESPONSE #1
The study of 1992 Hodgkin's disease in ZIP codes 11701, 11735 and 11758 did not look at individual exposures to chemicals; it only compared incidence of cancer in the study area to the incidence rates in New York.
COMMENT #2
Since concern was raised about increased Hodgkins, it should be obvious that the ATSDR should follow statistics in the area for a rise in cancer, non-carcinogenic health disease, and Hodgkins.
RESPONSE #2
The study showed a similar incidence of Hodgkin's disease for areas of the state with similar population density. In addition, Hodgkin's cases were plotted on a map and there did not appear to be any clustering of the cases in the area. Finally, the number of people exposed to water which was contaminated from the site is small. It would be difficult to relate differences in disease incidence to the site since the exposed population is so small.
COMMENT #3
Since the VOC's were produced in 1951-1976, can't it be assumed that Suffolk County's wells and private wells were contaminated even before sampling occurred and the population was therefore exposed? If so, why is ATSDR HARP not recommending follow-up?
RESPONSE #3
The public health assessment has been revised to reflect new information regarding private wells. The public water supply wells which are downgradient of the Preferred Plating site have not been contaminated from the time sampling began. Because the wells tap the deep Magothy aquifer, it is unlikely that they were contaminated in the past.
COMMENT #4
Is there a time limit on investigation of private wells?
RESPONSE #4
Although the survey of private wells was conducted in 1993 and is believed to be accurate, neither NYS DOH nor SC DHS have placed a time limit on how long we will follow-up on newly identified wells or on information that wells may be present in a particular area. Any wells that are found will be sampled and the results will be evaluated for further action.
COMMENT #5
Should a warning be placed in the deed to the property which warns about contaminated soils and groundwater?
RESPONSE #5
We do not believe a deed notation is necessary because remedial measures, when complete, will adequately address contamination which is a concern for human health.
COMMENT #6
What can be done about stopping the release of 7,000 lbs. per year of Freon 113 from Napco Security Systems?
RESPONSE #6

New York State Department of Environmental Conservation
Region I
SUNY Campus
Loop Road, Building 40
Stony Brook, New York 11790-2356
(516) 751-7900
COMMENT #7
Are the printed figures on Table 3, page 30, U.S. EPA Drinking Water Standards correct for organic compounds ethylbenzene, toluene, 1,1,1-trichloroethane, and xylene.
RESPONSE #7
The information for these chemicals is correct in Table 3.
COMMENT #8
The method of communication announcing public meetings is inadequate for the target population involved.
RESPONSE #8
The NYS DOH is cooperating with US EPA to improve the dissemination of meeting notices to the public.
