Dear
Illinois
State
Pollution
Control
Board,
My
name
is
Aldin
Polovina
and I am
from
waters
school.
My
classmates
and
I took
various
fieldtrips
to the
Chicago
River.
My
classmates
and I
took
tests
for
the Chicago
River.
The
tests did
not
turn out
very
well.
We ranked
our tests
with
numbers
1-4.
4 is
a great
score
and
i is a
horrible
score.
Most
of our
tests
were
l’s and
2’s
which
aren’t
good
grades.
Only
a
few
of
our
tests
came
back
as
4’s.
We
examined
how
we
have
locks
so
the
Chicago
River
water
doesn’t
go into
Lake
Michigan. When
we
finished
our
testing
we
put the
water
to
dissolve
and
to
see
what
and
how
much
the
Chicago
River
is
polluted.
When
our teacher
came
back
and
told us
the test
results,
the
dissolved
oxygen
had
a very
low
test
score.
Our teacher
talked
about
how
the
pollution
was
dumped
in
the
water
and
that
there
was no
oxygen
in
the
water.
Before
we went
to
examine
and
study
the
Chicago
River
we talked
about
the many
tests
we
were
going
to
take.
After
we
took
our
tests
we examined
the
bugs
in
the
Chicago
River.
We found
Saul
bugs,
blood
worms,
craws,
and
many
other
bugs.
Some
groups
that
went
to look
for
bugs
but never
found
them.
The
other
groups
we had
divided
into
almost
never
found
any
bugs.
When
we came
back
and we
examined
the bugs
we
found,
the
first
group
that
went
to
examine
found
any
bugs.
The
second
group
that
went
to
see if
there
were
any
bugs
only
found
a few
bugs.
The
third group
that
went
to
look
for
bugs
found
so
many
bugs.
They
found
Saul
bugs,
blood
worms,
craw
fish
and
many
other
big
bugs.
The
fourth
group
found
only
a
few
bugs.
When
we
came
back
and
tallied
up
the bugs
we
found
we
only
found
a
few.
I know
it’s
your
job to control
pollution
and
you should
really
not
pollute
the
Chicago
River
as how
much
it is
polluted
now.
We should
keep
Mother
Nature
as
beautiful
as
it could
get. We
do
not
want
to make
Mother
Nature
dirty.
Please respond.
Sincerely,
Aldin Polovina
