Death came in the water
E. coli breaks out at a
N.Y. county fair
BY AMANDA SPAKE
At first, the illness was a mystery. The
Washington County Fair in Greenwich, N.Y., was great fun, but two days later,
the Aldrich girls had become feverish, irritable, and lethargic. Their doctor
sent them to a local hospital and Kaylea, 2, seemed to improve. But 3-year-old
Rachel grew sicker. On Friday, September 3, she was rushed to the pediatric
intensive care unit at Albany Medical Center Hospital, where she and her sister
were found to be infected with the deadly E. coli 0157:H7 bacterium from
drinking water at the fair.
At Albany, Wayne and Lori Aldrich watched
helplessly as Rachel's heart stopped, cutting off oxygen to her brain. Her
kidneys failed and she was not able to breathe on her own. Late Saturday
afternoon, September 4, on the day she was to celebrate her fourth birthday,
Rachel died in her parents' arms.
Now, the Aldriches sit by Kaylea's bedside as she
remains in serious condition, on kidney dialysis like 10 other children who went
to the fair. They are among over 600 people thought to be infected with the
bacterium. If confirmed, this would be one of the largest E. coli 0157:H7
outbreaks on record. The great risk now, according to the New York State
Department of Health, is further person-to-person spread of the organism.
How did a supposedly safe drinking-water system
become the source of a major outbreak? The health department's theory is that a
torrential rainstorm in late August washed manure-laden water from cattle
exhibits into loose soil around an auxiliary well at the fairgrounds. This
contaminated surface water mixed with the well's usual source, a ground-water
aquifer, which had fallen low because of this summer's drought. Unlike other
wells supplying the fair, the auxiliary well was not chlorinated. Once the well
was in use, contaminated water was pumped to food and drink vendors. Two
vendors, one of whom has developed symptoms of infection, may have taken water
to another New York fair.
But the Greenwich fiasco points up a greater
problem: Treatment and monitoring of drinking water cannot be taken for granted.
Kristine Smith, spokesperson for the New York Department of Health, says that
since the fairgrounds' water system was considered private, only limited
treatment and testing was mandated by the state, and the system was not subject
to U.S. Environmental Protection Agency regulations.
But J. Charles Fox, assistant administrator for
the Office of Water at the EPA, is not so sure. "This seems to be what we
call a transient noncommunity water system," says Fox: It is a system that
serves the public on an intermittent basis. Smith says the EPA is wrong because
the system "does not operate for 60 days a year"–though, as the
Washington County Fair office confirms, it serves thousands of people at
different events throughout the year.
Higher standards.
Upcoming EPA rules will probably require disinfection of ground-water systems
like this one, Fox says. And the EPA has been tightening standards for all water
systems since renewal of the Safe Drinking Water Act in 1996.
But states don't always enforce testing
requirements, and water-systems managers don't always report violations to the
state or the federal government. A recent draft of an EPA audit of 1,800 public
water systems and 27 state programs shows monitoring of water quality and
reporting of violations are, in Fox's words, "exceptionally weak."
While many of the infractions identified in the audit are inconsequential, about
one third involve failure to report excessive coliform bacteria, such as E. coli,
or failure to treat water for bacterial contaminates. Fox says that "there
is nothing in this that should make people feel less confident about their
water." Yet EPA studies show that the U.S. drinking water system
"suffers from long-term neglect and serious deterioration." The cost
for fixing the problem is an estimated $12.1 billion–just to meet existing
EPA standards, not the more stringent upcoming regulations.
Within the next month, everyone on a water system
with more than 25 customers should receive in the mail his first "Consumer
Confidence Report." The reports are now required by law to inform consumers
about microbial and chemical contaminants and any violations of EPA regulations
by the water supplier–at least those that have been reported. But as the
outbreak at the Washington County Fairgrounds shows, it is not what we know
about our water that may be most significant, but what we don't know!
