Bayshore High Gets Clean Bill of Health on Irrigation Wells But Questions Remain

BRADENTON – While the mystery surrounding the inordinate number of rare
cancer cases among students and faculty at the old Bayshore High School
remains unsolved, the groundwater and two irrigation wells at the
current campus have tested clean, according to results presented at Tuesday's
Manatee School Board workshop.
Brian Moore, principal engineer at GHD,
and GHD senior geologist Kenneth Caldwell, presented the board with
findings from a recent study, undertaken as the district and alumni
continue to grapple with questions about the school's history and the
high number of alumni suffering from rare illnesses.
The firm took groundwater samples at two irrigation wells on campus
property this summer, testing for a litany of contaminants. Zinc,
nickel, lead and mercury were detected, but at acceptably low levels
that presented "no significant concerns." Moore explained that these
metals occur naturally and are expected to be in the aquifer at the low levels discovered (click here to view test results, and here to
view the conclusion summary).
While the results are important in establishing the safety of
conditions for the students and faculty at the current campus (which was
built on the same footprint of the old campus in 1997), they
unfortunately offer no answers in the ongoing quest of alumni to find
out whether and to what extent water contamination factored into the
cancer anomalies. During the workshop, the district confirmed that it
still cannot definitively answer the question as to where the school got its drinking
water prior to being connected to public water, sewer and solid waste
in April of 1998.
As per a joint meeting between
the school board and county commission in late May, Jennifer Bencie,
Manatee County's health officer for the Florida Department of Health, is
planning to work with alumni willing to provide medical records to
establish whether or not an identifiable cancer cluster exists. Bencie's
department is scheduled to launch an initiative in October for Bayshore
alumni to provide such information, which will be used in conjunction
with the statewide cancer registry that has been collecting data on
cancer incidences since 1981.
Bencie has said that her department needs more information, describing a process that has thus far been operating in reverse. More typically, an exposure source is discovered and then sicknesses known to be associated with the toxin are studied among the exposed populations. If you know that a particular toxin was in a population's drinking water for a long period of time, and then cancers associated with that toxin are happening among that population at a much higher rate than is statistically probable, causation is much easier to establish. In Bayshore's case, there are a myriad of different illnesses happening at heightened rates, and the search is for the possible sources, which is much more complicated.
Cheryl Jozsa, a Bayshore alum whose sister was one of four 1979
graduates known to have passed away at a young age from a rare leukemia,
has made the only earnest effort thus far to contact alumni and collect
information. By starting a Facebook group dedicated to the issue, Jozsa discovered hundreds of alumni who were
either sick or dying at young ages and from unlikely causes–particularly
leukemia. In fact, Jozsa says the group learned of four
more leukemia cases just since May's joint meeting.
Jozsa said that Dr. Richard Smith, a biostatistics
professor at the University of North Carolina who has been working with the alumni group, had
originally put their self-reported leukemia instances (17 where
2.45 would be expected) at one in a billion odds and already considers it a cancer cluster. She said that when Dr.
Smith was made aware of the 4 additional cases reported, he told her
that were he to replace 17 with 21, it would take the odds to one in 400
billion.
Most of the victims and
their families had no idea that so many Bayshore alumni had fallen ill.
Jozsa and other alumni have long called for an official effort by the
county and school district to notify alumni and ask those who think that
they or a family member may have been affected to come forward. Thus
far, no such effort has been made. Jozsa believes that the obvious answer to where the old school got its drinking water is from wells that had previously been on campus and thinks that contaminants to that source–possibly from the nearby Riverside Products EPA superfund site–may be at the root of the abnormal number of illnesses among alumni.
"I'm glad the school district followed through on having these irrigation wells tested," said Jozsa, "but it is my opinion that the GHD report isn't nearly thorough enough. On six different occasions in the report, it says 'information or data was unavailable,' and it never gets into where the drinking water for the old school came from, which is the most important part. If anyone thinks that these tests of the irrigation wells clear the controversy of the Bayshore High illnesses, they're wrong. We're going to keep fighting until we get complete answers."
