WATER USED

RATED HIGH
Investigation by w w. Han

Best in Country.

laH w otOlE O. ASOA - ~ ~
filtered at the municipal plant, cen
forms to the highest standard In the
country, according to a report made
by w. w. Hanford OF the University
of North Dakota, after conducting q
special Investigation. The report was
made at the meeting Of the Water and
Light Commission last night.
For the first time in the history OF
the city, samples Of tap water taken
from the taps in webbers restaurant,
the City Hall and the Northwestern
hotel. This action was taken, on the
Recommendation Of the state board Of
health. It would be possible, accord
ing to experts, for water to- become
contaminated in the water mains after
leaving the filters.
Water Never Boiled Here.
The report Of the investigator. up
holds the reputation OF the local
plant. Since the erection OF the local
altering system several years ago, 1t
has never been necessary for users to
boil the water to make it safe for
drinking purposes.
Following, is the, report OF W. W.
at the inlet and at the Alter:
I'VE have the following report to
make upon samples OF water collect
ed. on June IL, 1917:
sample-Raw river water. Bacter-
Ia per &C. on agar at 87.6 G. Intes-
tinRl o~rganizisns Of the colon type
present in i &C.
sample-Tap Water. Bacteria per
&C. on agar at s7.5 c., /. Gas forma-
ton in iactose both using s ten &C.
paintings, s. Gas formation in lactose
broth using 3 n &c. paintings, 8.
Prom the above analysis it will be
seen that there is q considerable num-
Der OF intestinal organisms Of the CO.
Ion type present in the raw water.
This water should be filtered and
treated before using. The tap water
- in excellent condition from a bac-
THEOLOGICAL standpoint and lives up to
the standard prescribed by the U. s,
Public Health Service for water used
On interstate carriers. This standard
is the highest standard in the country,
The efficiency of the plant ia 99.8 per
cent. The sample of the h~ypochlorite
used is to be analysed and samples
are to be collected in various places
in the downtown district in the near
future.
yours very truly,

High Standard Set.
"All' Of the samples have a low bac
terial count and show no evidence o
intestinal organisms Of the colon typ
in so &C. amounts. All three sample
live up to the standard set BY the u
8. Public Health Service for waite,
used In interstate trafic. This is
very high standard. From these an
earlier, 1t would seem that sufflcien
hypochlorite was being used to, secur'
q water safe for drinking purposes
1.-THE hypochlorite shows by anal
alysis, 27.b per cent available chlorin
This is considerably in excess Of tina.
contained in the old hypochlorite. I
care had been taken in securing tn,
sample from the bottom of the drum
no doubt, the content of availabl,
chlorin would have been higher. M
especial care was taken in sampling
!. O., the strength Of the hypo as uset
from the drum wac determined.
