TALLAHASSEE?The Florida Department of Health (DOH) and the Florida
Department of Environmental Protection (DEP) today released their initial
findings regarding The Acreage Cancer Review. DOH conducted a Level I cancer
cluster investigation and DEP conducted extensive drinking water sampling within
the community.
DOH?s Level I investigation was conducted to determine if there is evidence of
higher than expected rates of cancer in The Acreage community from 1995-2007.
The Level I investigation involved the review of information surrounding the
cases, the geographic area in question and the cancer types involved. DOH sent
its findings to the Centers for Disease Control and Prevention which endorsed
the report as ?thorough and scientific.?
The incidence of pediatric brain cancer
was specifically looked at, and six cases were found during the period from
1997-2007. The report also cites total cancer rates in The Acreage may be
elevated. Cancer rates have been increasing from 2000-2007, although the
increases may be a reflection of dated population numbers.
?We recognize this is
a difficult time for residents of the Acreage,? State Surgeon General Ana M. Viamonte Ros, M.D., M.P.H., said. ?We will proceed with a Level II analysis to
ensure we have the most complete and accurate information for the community.?
DOH has determined a Level II cancer cluster investigation will begin promptly.
The Level II analysis will be conducted to:
? recalculate cancer rates using
more recent population estimates;
? verify if any particular brain cancer is
more common than expected; and
? describe the residence history and other risk
factors of pediatric brain cancer cases through interviews.
Understanding the
community?s concerns regarding possible drinking water contamination and serving
as a partner to the DOH, DEP sampled 50 drinking water wells in a 36 square mile
area within the community and took one well sample from the Seminole Improvement
District water treatment plant to determine if contamination is present in
groundwater. DEP?s preliminary findings show all residential wells meet drinking
water standards. However, a raw water sample ? meaning before the treatment
process takes place ? from one of the five water supply wells at the Seminole
Improvement District water treatment plant did show a minor exceedance for
radium 226.
In an abundance of caution due to the minor exceedance, DEP this
week conducted additional water quality sampling. When initial sampling took
place, DEP only sampled one of the supply wells at the Seminole Improvement
District water treatment plant. This week, DEP sampled all five wells that
supply water to the treatment plant as well as the finished treated water before
distribution to customers, focusing on radium 226. The plant, which is in
compliance with DEP?s regulatory requirements, uses reverse osmosis which is a
state of the art filtering water treatment technology. DEP does not expect to
see an exceedance of radium 226 in the post treatment water sample.
Radium is a
naturally-occurring radioactive metal, which occurs at low levels in virtually
all rock, soil, water, plants, and animals. Radiologicals that occur in
groundwater above federal and state standards can be easily treated.
?DEP is
committed to conducting a thorough evaluation of the drinking water samples
collected,? said DEP Secretary Michael W. Sole. ?Recognizing the importance of
the samples to the community?s peace of mind, DEP is having the sample that
showed a minor exceedance for radium 226 reanalyzed and has increased the number
of samples taken in the area. We want to make sure that the information we
provide the public is accurate and complete.?
While the current timetable to
release DEP?s preliminary results could change depending on the results of the
new testing, DEP still anticipates having a complete report by late September.
