PETITIONED PUBLIC HEALTH ASSESSMENT
WALLINGFORD, NEW HAVEN COUNTY, CONNECTICUT
The Air Quality Petition Site, which is the Town of Wallingford,Connecticut, is considered an indeterminate public health hazarddue to the lack of data on the levels of contaminants in ambientair. Relatively large amounts of pollutants are being releasedfrom automotive, industrial, and other sources in the Wallingfordarea. There is a potential for exposures of health significancebased on the amounts of contaminants, and the presence ofconditions that would maximize pollutant levels. Thoseconditions are that Wallingford is in a valley and temperatureinversions occur. The potential for exposures of healthsignificance could be evaluated by long-term monitoring of theair in Wallingford.
The data available to ATSDR suggest that the complaints expressedby SPARROW and other Wallingford citizens are limited to a smallportion of the 40,000 or more residents of Wallingford. Datawere insufficient to link the complaints with any specific cause. However, there is a possibility that the reporting individualsare more sensitive to environmental contaminants than the generalpopulation.
The number of cases of cancer in Wallingford from 1964-1988 iswhat would be expected based on the rate for Connecticut, exceptfor buccal cancer and multiple myeloma. Numbers of those caseswere lower than expected compared to rates for the State.
The toxicologic data reviewed indicate that the chemicals inWallingford's air could cause many of the symptoms listed in thecomplaint logs kept by SPARROW members. However, nearly all ofthe symptoms would occur only after high levels of exposure. There is no indication from the limited air monitoring studiesthat high levels of exposure have occurred or are occurring.
During the development of this public health assessment, ATSDRdetermined that the following activities are necessary to furtherclarify and/or quantify the public health hazard at this petitionsite.
- A more thorough characterization of Wallingford air qualityshould be undertaken. To implement this, a panel ofinterested and knowledgeable representatives from theConnecticut Departments of Health Services and EnvironmentalProtection, the Town of Wallingford, SPARROW and/or otherconcerned citizens, the major industries in Wallingford, andthe U.S. Environmental Protection Agency should be convened. ATSDR would be available, if requested, to assist the panel. This panel could help define the scope of such monitoring,and possibly share resources.
- The panel should address, as a minimum, the following:
- the number and types of parameters to be sampled thatwould provide meaningful insight into Wallingford's airquality;
- numbers, types, and locations of sampling stations to beincluded;
- sources of funds, labor, and other resources needed tocarry out the program; and
- project milestones and responsibilities for reportgeneration and data interpretation.
- Minimally, the monitoring program should include a network ofair monitors located strategically within the Town andoperated for at least a full year to reflect the full rangeof seasonal meteorologic conditions affecting migration anddispersion of air pollutants generated near or within theWallingford air basin.
- Complete local meteorologic data for the area should berecorded throughout the duration of air monitoring.
- The baseline monitoring program should also include analysisfor ambient air parameters (ozone, carbon monoxide, nitrogendioxide, sulfur dioxide, particulate matter, lead, othermetals, and inorganic chemicals) to serve as indicators ofgeneral air quality in Wallingford. That information wouldbe useful for better understanding the effects of localterrain and meteorology on the dispersion or concentration ofarea air pollutants, and might suggest areas warrantingcloser review. Such review could include specific point-of-exposure monitoring to support further, more detailedanalysis of the health implications of airborne pollutantexposures. That type of data could also be compared withsimilar data for other urban areas both within and outsidethe State of Connecticut.
- A mobile monitoring program should be considered to betterunderstand the nature and spatial distribution of organic airpollutants in the city. The array of organic compoundsselected for review should be representative of industrial,commercial, residential, and automotive emissions.
- If exposures of health significance are identified in themonitoring program suggested here, a symptom\prevalence orother appropriate epidemiologic study is suggested todetermine the impact of those exposures.
The Air Quality Petition Site, which is the Town of Wallingford,Connecticut, has been evaluated by the ATSDR Health ActivitiesRecommendation Panel (HARP) for appropriate followup with respectto health activities. Because of the potential for exposure toairborne contaminants, ATSDR is considering a program to educatethe community about the health effects and sources of airpollution. Studies of health effects possibly due to airbornecontaminants are not being considered at this time, because ofthe lack of air monitoring data adequate for determining exposurelevels. However, if data become available suggesting that humanexposure has occurred or is occurring, ATSDR will reevaluate thissite for any additional indicated follow-up.
Public Health Actions
Based on the data evaluated and the recommendations made by HARP,the following Public Health Action will be taken.
ATSDR will coordinate the convening of the panel recommended previously.
The public health assessment for the Air Quality Petition site,Wallingford, Connecticut was available for public review andcomment from July 20 through August 18, 1992. A summary of thecomments received can be found in Appendix Four.

CDHS alsoprovided the population figures used to calculate the age-adjusted incidence rates. Population data from Wallingford andConnecticut for 1975 were used in the various calculations. Allanalyses were done by staff of the Agency of Toxic Substances andDisease Registry (ATSDR) using a Lotus 123R program provided byCDHS. This program calculates expected numbers of cases, age-adjusted incidence rates, and whether the results are higher orlower than what would be expected by chance.

COMMENTS RECEIVED ON THE AIR QUALITY PUBLIC HEALTH ASSESSMENT
The Air Quality Public Health Assessment was available for publicreview and comment from July 20, 1992 through August 18, 1992. The Public Comment Period was announced in local newspapers. Copies of the public health assessment were made available forreview at the Wallingford Public Library, and the ProgramPlanning Office of the Town of Wallingford. In addition, thepublic health assessment was sent to 11 individuals ororganizations who had requested that they receive copies. Comments were received from one individual, a staterepresentative, and the Town of Walling
|COMMENT:||The commenter agreed with ATSDR's conclusions that the chemicals in or that could be in Wallingford's air could cause many of the reported symptoms, and that additional monitoring is needed.|
|RESPONSE:||ATSDR appreciates the support.|
|COMMENT:||It was suggested that the Connecticut Department of Environmental Protection's (CDEP) list of air violations be compared to SPARROW's complaint logs to see if there is a significant correlation.|
|RESPONSE:||In 1990, ATSDR reviewed the CDEP's air pollution complaint logs and air quality notices of violation for the Wallingford area. None of the air pollution complaints, including those for 1984, resulted in a notice of violation. The only notices of violations were for technical violations of the law, not for actual releases of pollutants. Thus there is nothing to compare to SPARROW's logs of health complaints.|
|COMMENT:||The resource recovery plant is mentioned as a facility identified in an odor complaint; the report should note the plant was not yet built in 1984 when SPARROW's health complaints were recorded.|
|RESPONSE:||The public health assessment has been revised to mention this fact about the resource recovery plant.|
|COMMENT:||The panel of interested representatives you suggest to establish monitoring parameters should be expanded to include representatives of workers as well as management in the major industries in Wallingford.|
|RESPONSE:||ATSDR supports having workers participate in the panel as representatives of the public.|
|COMMENT:||Town officials should ban any more industry in Wallingford.|
|RESPONSE:||This matter should be addressed directly to the Town of Wallingford.|
|COMMENT:||The location of Wallingford in a valley would prevent easy dissipation of industrial emissions.|
|RESPONSE:||There is an extensive discussion in the public health assessment of this and other factors that might affect the air quality in Wallingford.|
|COMMENT:||There are six schools and a Little League field in a position to receive polluted air currents.|
|RESPONSE:||As mentioned in the public health assessment, the air quality around the Little League field was not found to be a problem in one evaluation. The overall quality of the air in Wallingford is not known which is why ATSDR is recommending comprehensive monitoring.|
|COMMENT:||The commenter and her family have experienced health problems which they associated with poor air quality.|
|RESPONSE:||Data from comprehensive air monitoring and on the specific health effects are needed to address this concern, and they are currently not available. ATSDR recommends in the public health assessment that a health study be done if the comprehensive monitoring identifies levels of air pollution that could be a health hazard.|
|COMMENT:||The commenter wondered whether the rate of miscarriages in Wallingford is greater than for other nearby towns.|
|RESPONSE:||ATSDR could not identify any database with the information that could be used to answer this question.|
|COMMENT:||Will ATSDR fund the monitoring they recommend in the public health assessment?|
|RESPONSE:||ATSDR believes that this problem can best be addressed through a multi-agency effort. As indicated on page 31 of the public health assessment, ATSDR is committed to convening a multi-agency panel on air quality in Wallingford. This panel, which would include representatives from local, state, and federal agencies, and also private industry, would have funding identification as one of its tasks. As stated in the public health assessment, one of the panel's purposes is to facilitate resource sharing among its members.|
Comments and responses are summarized below. The comment letterscan be requested from ATSDR through the Freedom of InformationAct.
