OFF Kenosha. It is understood that a
similar order is being sent by the
state board of health to every city
with sewers emptying into the lake.
~Thesorder of the state board is based
on an examination in Kenosha made
by State Chemical Engineer F. j. Tully.
What the State Board Says.
The following is the letter to the
city from the state board of health
and with it is the report and recon-
mendations of the chemical engineer.
There is enclosed herewith a copy
of MIR. Tully's report upon an investf-
cation of your public water supply.
We are pleased to note that your puri-
fication plant is apparently being op-
Grated in an efficient manner and sa-
tisfactory publication of the water
being secured. You will note. how
ever, in the recommendations that con-
sideration be given to the treatment
of the sewage by your municipality.
This is a matter which has previously
been token nm with vour CITY officials,
and In - ct, is ae = ei5af DOR
in connection with all lake cities. Not
only is the discharge Of sewage into
the lake without treatment menace
to your public water supply, but it is
also dangerous in connection with
bathing during summer because this
untreated sewage undoubtedly causes
such pollution of bathing beaches at
times as to make bathing unsafe. We
raa1iza fbo+
dertaking for the municipality, but
believe that consideration should be
given it at an early date in order that
your sewerage system may be gradu-
ally so developed as to collect the sew
age at points suitable for treatment.
The matter of treatment can then be
taken up and installed without a heavy
burden that would otherwise be neces-
sary. Yours very truly, State Board
of Health, c. M. Baker, state sanitary
engineer"
