Pollution sources to be discussed in Michigan and
Reports show E. coli comes from many places

It's going to take some changes by lots of people to
clean up the St. Joseph River.
People from agencies that are charged with protecting
the environment in Michigan and Indiana recently completed
a study on one form of pollution, E. coli, and found it's
not all coming from pipes that dump somebody's waste into
It's coming from things like private septic systems and
livestock wading into the river or the smaller streams
that run into it.
Meetings on the research will be held at 9:30 a.m. (Michigan
time)Wednesday in the Love Creek Nature Center in Berrien
Center and at 6 p.m. (Indiana time) Thursday in the Mishawaka-Penn-Harris
Library in downtown Mishawaka.
E. coli is tiny bacteria that comes from the intestinal
tract of warm-blooded animals.
The bacteria don't live long outside the bodies of animals
or birds, so if E. coli is found in the water, there are
traces of feces there, too.
And since it's fairly easy to test for E. coli, it's
used as the indicator of possible problems.
The bacteria live naturally in our bodies, and most of
them are harmless. But some of them and some of the pathogens
that accompany them can make people sick.
The St. Joseph River has been designated as impaired
from where it enters Indiana east of Elkhart through Elkhart
and St. Joseph counties in Indiana and Berrien County
in Michigan until it runs into Lake Michigan.
Because of that, the Michigan Department of Environmental
Quality (MDEQ) and the Indiana Department of Environmental
Management (IDEM) have written Total Maximum Daily Load
(TMDL) reports required by the federal government.
The first drafts of those reports will be reviewed at
Staci Goodwin, who is in charge of the Indiana side of
the research, said it shows that the E. coli is "probably
something that's there (in the river) all the time."
That means it's not just washing in during heavy rains.
"It can be just that people need education,"
she said. "Their septic systems may just not be maintained.
It may never have been brought to people's attention that
letting cattle stand in the stream could be causing a
She said IDEM will write an implementation plan on how
to control E. coli, although most of the actual work will
have to be done locally.
Christine Alexander, with the Michigan agency involved,
said that state will also come up with an implementation
The Michigan report says units of government along the
river may be required to control sources, including storm
The Indiana report discusses studies and projects intended
to eliminate all sources of pollution in the St. Joseph
or its tributaries and said they have begun to have some
The two reports include technical informational with
the exact amounts of E. coli found at various points in
the river along with graphs showing how conditions in
the river, including the volume of water, relate to the
amount of pollutants.
The object of all that is to figure out how much E. coli
discharged into the river from various sources has to
be reduced in order for the river to be clean enough for
people to swim in it.
The public now has a chance to comment on the reports,
and those reports must be submitted to the U.S. Environmental
Protection Agency for approval.
The IDEM reports says that the river is clean enough
not to be considered impaired from where it enters Indiana
from Michigan to Elkhart.
Although there is E. coli in the river even when the
weather is dry, the reports from both states show conditions
are worse just after a rain. Rain washes E. coli from
sources such as agriculture into the stream but probably
the largest increase comes from sewage plants along the
In most of the sewer systems in the United States, storm
water and sewage from homes and businesses all go to the
water treatment plant.
On a normal day that works fine, but during a rain storm,
there's too much water for the treatment plant to handle,
so it goes directly into the river through an overflow
pipe, taking sewage from homes and families with it.
Elkhart and Mishawaka have submitted plans to correct
the problem to the state and federal governments. Goshen
and Wakarusa must submit their plans by the end of 2004
and South Bend must submit its plans by the end of 2005.
In Michigan, Niles and St. Joseph have started the process
of eliminating the discharges.
