Bandar Lampung City. Photoreactivation is a direct process of repairing a damaged DNA with 
the help of ultraviolet in the range of 320-370 nm. Research is designed to acknowledge the effect
of time exposure and UV vis ray?s intensity to numbers of Coliforms and E.coli. The results prove
the effect of UV exposure time on the increase of coliform which is 60,2% (p-value=0,0001). The
increase of coliform happens after 180th minutes of exposure. But, in this research there is no
effect of UV?s intensity towards both numbers of coliform (p-value = 0,152) and E.Coli (pvalue=0,578).
Besides
buying
a
refilled
mineral
water
from
a
water
depot
whose
disinfecting
with

UV
ray
and
ozone
combined,
closing
the
gallon
of
mineral
water
since
the
first
day
being
used
to

avoid
being
exposed
by
UV
vis
ray
from
the
sun
is
a
must-do
to
avoid
photoreactivation
process.
