The 15 March 1995 FAQ still quotes the 1993 date. I thought I'd check Mr. Lund's claim. Quoting from the journal in question [reminder--BOA doesn't apply to quoted material]:

     Suction-Drain Injury in a Public Wading Pool - North Carolina, 1991

          On June 16, 1991, a 3-year-old girl playing in a public wading
     pool sat on the pool's uncapped suction drain.  The child appeared to
     be stuck on the drain, and the pool attendant quickly truned off the
     pool's suction pump.  As a consequence of sitting on the drain, the
     child sustained severe internal injuries requiring surgical repair.
     This report summarizes the investigation of this incident by the
     North Carolina Department of Environment, Health, and Natural
     Resources (DEHNR) and describes safety measures to prevent injuries
     among children caused by pool suction drains.

          Following the episode at the wading pool, the child was examined
     at a hospital and had perianal bruising and prolapse of the rectal
     mucosa.  The prolapse was manually reduced, and a pelvic computerized
     tomography scan showed no evidence of a rectal leak; however, by June
     17, she had evidence of localized peritonitis.  An exploratory
     laparotomy revealed a long anterior laceration of the seromuscular
     layer of the rectosigmoid colon; the mucosal tube was intact but
     ischemic and was separated circumferentially from the outer layers of
     the bowel wall.  The laceration was repaired and a sigmoid colostomy
     performed.

          The investigation by the DEHNR revealed that the wading pool
     where this injury occurred had a three-quarter-horsepower suction
     pump that was not linked to the adjacent adult pool or any other
     outlet.  At the time of the injury, the antivortex [sic] drain cover
     that had previously covered the drain had been removed.  Since the
     incident, the antivortex [sic] drain cover has been secured to the
     drain to prevent further suction injuries.

          _Editorial Note:_ The findings in this investigation are
     consistent with those from previous reports of abdominal injuries
     among children who sit directly on uncovered openings or vents
     capable of forming a strong vacuum when covered (1).  When a child
     sits on an unprotected suction-drain vent, the child's perineum can
     form a firm seal that creates a vacuum capable of relaxing the anal
     sphincter.  This negative pressure on the exposed rectal walls can
     result in prolapse or intussusception; this, in turn, usually
     produces a full-thickness anterior bowel tear, creating the potential
     for evisceration of the mobile small intestine through the laceration
     and the anal canal.  Damage to the mesentery can produce extensive
     irreversible small bowel ischemia requiring resection.

          Since May 1, 1991, North Carolina has required all newly
     constructed public wading pools to be equipped with a surface skimmer
     and with interconnected double drains to prevent suction-drain
     injuries.  However, pools constructed before May 1, 1991, have been
     allowed to continue operating with a single drain.  The public pool
     involved in this incident was built before the standards became
     effective; however, the pool had been inspected 12 months before the
     injury occurred and had had an antisuction cover in place over the
     drain opening at that time.

          Because a child may be injured within seconds of sitting on a
     drain, adult supervision alone does not effectively prevent
     suction-drain injuries.  Suction-drain injuries can be prevented
     through interventions that prevent vacuums from forming when the
     vents are covered.  Existing pools that may have a single suction-
     drain or multiple suction-drains that can be isolated by valves
     should be equipped with antivortex [sic] covers or with grates at
     least 12 inches by 12 inches over the drains to prevent the
     possibility of a vacuum forming if a child sits on a suction-drain
     opening (2).  In addition, standards of the American National
     Standards Institute/National Spa and Pool Institute and the American
     Public Health Association specify that drain covers be secured in a
     way to prevent removal without special tools (2,3).  Also,
     maintenance personnel should routinely inspect pool drains to ensure
     covers remain secure.  Pools should not be operated if a suction-
     drain cover is missing, broken, or inadequately secured (2).

          For new pools, water circulation systems should be constructed
     so that suction pumps are linked with more than one drain outlet; for
     example, the pump may draw water from two drains in the deepent part
     of the pool or from one drain and a surface skimmer, thus preventing
     a tight seal from forming if one drain is covered.  In addition to
     these barriers, water-safety instruction courses should include
     specific instructions on the prevention of injuries involving pool
     equipment.

The good news is Cornell University (my source) has the Journal of Pediatric Surgery, the bad news is it didn't start receiving it until 1986.

I second Mr. Lund's request for a quote of the article from the Journal of Pedaitric Surgery (1). Perhaps there's a reader out there who works at a Cancer Institute, or is an R. N.?

I have checked cathouse/urban.legends/misc/pool.drains, and frankly it does not sound as voracious as the above article.

FAQmeister: How certain are you of the 1993 date in the FAQ? How about updating the FAQ to record this earlier (1991) known occurrence? If reference (1) turns up an even earlier instance, I'd encourage the FAQ to report that, instead.

Cathousemeister: Shouldn't this be filed under medical?

ObUL: Agencies that run public pools, which are known to be controlled by

       members of a race I am not a member of, deliberately designed pools
       to eviscerate the intestines of young members of my racial group.

ObDecanter?: These agencies are, in turn, controlled by a Trilateral

Comission/Freemasons/Council on Foreign Relations conspiracy.
