Most
of
the
urban
population
in
India
use
UV
filtration
at
home
for
drinking
water.
Similarly,
there
are
a
large
number
of
products
available
in
the
market
that
does
water
treatment
and
claims
to
produce
water
quality
as
per
the
standards
required
for
drinking
or
recreational
water.
The
question
is
how
does
the
end-user
know
that
the
water
treatment
units
are
working
in
perfect
condition?
The
answer
lies
in
developing
innovative,
rapid
and
cheap
water
monitoring
sensors
that
can
be
deployed
in
houses
as
well
as
industrial
waste
water
treatment
units,
which
will
be
able
to
quantify
the
level
of
pathogens
and
heavy
metal
in
water,
says
Sushanta
Mitra,
assistant
vicepresident
(Research)
and
professor
of
mechanical
engineering,
University
of
Alberta,
Canada.
A
team
led
by
Mitra
has
developed
a
rapid
water
monitoring
sensor
which
can
detect
a
small
amount
of
E.
coli
(one
of
the
common
pathogens)
in
water.
