THE ATSDR PUBLIC HEALTH ASSESSMENT: A NOTE OF EXPLANATION

This Public Health Assessment was prepared by ATSDR pursuant to the Comprehensive Environmental Response, Compensation, and

Liability Act (CERCLA or Superfund) section 104 (i)(6) (42 U.S.C. 9604 (i)(6)), and in accordance with our implementing regulations
(42 C.F.R. Part 90). In preparing this document, ATSDR has collected relevant health data, environmental data, and community health
concerns from the Environmental Protection Agency (EPA), state and local health and environmental agencies, the community, and
potentially responsible parties, where appropriate.

In addition, this document has previously been provided to EPA and the affected states in an initial release, as required by CERCLA
section 104 (i)(6)(H) for their information and review. The revised document was released for a 45-day public comment period.
Subsequent to the public comment period, ATSDR addressed all public comments and revised or appended the document as appropriate.
The public health assessment has now been reissued. This concludes the public health assessment process for this site, unless additional
information is obtained by ATSDR which, in the agency’s opinion, indicates a need to revise or append the conclusions previously
issued.

Final Release

Forward
The Agency for Toxic Substances and Disease Registry, ATSDR, was established by Congress
in 1980 under the Comprehensive Environmental Response, Compensation, and Liability Act,
also known as the Superfund law. This law set up a fund to identify and clean up our country's
hazardous waste sites. The Environmental Protection Agency, EPA, and the individual states
regulate the investigation and clean up of the sites.

Since 1986, ATSDR has been required by law to conduct a public health assessment at each of
the sites on the EPA National Priorities List. The aim of these evaluations is to find out if people
are being exposed to hazardous substances and, if so, whether that exposure is harmful and
should be stopped or reduced. If appropriate, ATSDR also conducts public health assessments
when petitioned by concerned individuals. Public health assessments are carried out by
environmental and health scientists from ATSDR and from the states with which ATSDR has
cooperative agreements. The public health assessment program allows the scientists flexibility
in the format or structure of their response to the public health issues at hazardous waste sites.
For example, a public health assessment could be one document or it could be a compilation of
several health consultations - the structure may vary from site to site. Nevertheless, the public
health assessment process is not considered complete until the public health issues at the site are
addressed.

Exposure: As the first step in the evaluation, ATSDR scientists review environmental data to
see how much contamination is at a site, where it is, and how people might come into contact
with it. Generally, ATSDR does not collect its own environmental sampling data but reviews
information provided by EPA, other government agencies, businesses, and the public. When
there is not enough environmental information available, the report will indicate what further
sampling data is needed.

Health Effects: If the review of the environmental data shows that people have or could come
into contact with hazardous substances, ATSDR scientists evaluate whether or not these contacts
may result in harmful effects. ATSDR recognizes that children, because of their play activities
and their growing bodies, may be more vulnerable to these effects. As a policy, unless data are
available to suggest otherwise, ATSDR considers children to be more sensitive and vulnerable to
hazardous substances. Thus, the health impact to the children is considered first when evaluating
the health threat to a community. The health impacts to other high risk groups within the
community (such as the elderly, chronically ill, and people engaging in high risk practices) also
receive special attention during the evaluation.

ATSDR uses existing scientific information, which can include the results of medical,
toxicologic and epidemiologic studies and the data collected in disease registries, to determine
the health effects that may result from exposures. The science of environmental health is still
developing, and sometimes scientific information on the health effects of certain substances is
not available. When this is so, the report will suggest what further public health actions are
needed.

Conclusions: The report presents conclusions about the public health threat, if any, posed by a
site. When health threats have been determined for high risk groups (such as children, elderly,

2
­
Final Release

chronically ill, and people engaging in high risk practices), they will be summarized in the
conclusion section of the report. Ways to stop or reduce exposure will then be recommended in
the public health action plan.

ATSDR is primarily an advisory agency, so usually these reports identify what actions are
appropriate to be undertaken by EPA, other responsible parties, or the research or education
divisions of ATSDR. However, if there is an urgent health threat, ATSDR can issue a public
health advisory warning people of the danger. ATSDR can also authorize health education or
pilot studies of health effects, full-scale epidemiology studies, disease registries, surveillance
studies or research on specific hazardous substances.

Community: ATSDR also needs to learn what people in the area know about the site and what
concerns they may have about its impact on their health. Consequently, throughout the
evaluation process, ATSDR actively gathers information and comments from the people who
live or work near a site, including residents of the area, civic leaders, health professionals and
community groups. To ensure that the report responds to the community's health concerns, an
early version is also distributed to the public for their comments. All the comments received
from the public are responded to in the final version of the report.

Comments: If, after reading this report, you have questions or comments, we encourage you to
send them to us.
