March 31, 2011 Hands-free faucets harbor germs, Johns Hopkins study
says: a team at the Johns Hopkins Hospital in Baltimore
has discovered that at their facility, electronic faucets were
more likely to be contaminated with Legionella bacteria than
the old-fashioned manual type. It is believed the bacteria counts
are higher in the electronic faucets because they have a complicated
system of valves that is difficult to clean, researchers said.
Apri1 1, 2011 Study: Auto Faucets Have More Bacteria Than Manual Sinks
John Hopkins Hospital Replaced Faucets In Light Of Findings
When compared to water samples from old-fashioned manual faucets,
the electronic ones had 50 percent more bacteria growing in
them, and the bacteria grew much faster, the study showed. Bova
and his team said they believe the parts that make up the motion-censored
technology are to blame. There are a lot of little grooves and
folds to the plastic parts where bacteria can get trapped, he
said.
March 31, 2011 Doctors at Baltimore’s Johns Hopkins were in for
a shock when they checked their water systems. Water
samples taken from 20 laser activated faucets contained an alarming
percentage of Legionella bacteria.
March 31, 2011 Johns Hopkins found electronic faucets are cozier than
old-fashioned ones for bacteria. Tests detected the
bacteria responsible for Legionnaire's disease in more than
half the faucets tested. The hospital replaced them in areas
where patients receive care.

their newest patient unit. The only non-electronic,
LEED metered faucet designed to prevent Legionella bacteria
and provides three temperatures of water for washing hands.
