The wet weather of the last few weeks has caused some communities to
dump sewage into the Great Lakes. That’s triggering health concerns
for this summer. The Great Lakes Radio Consortium’s Chuck Quirmbach
reports:
Frequent heavy downpours have overwhelmed some lakeside sewer
systems. Some cities have dumped partly treated or untreated sewage
into the Great Lakes, instead of causing sewer backups in local basements.
Jeffery Foran is an aquatic toxicologist and president of the Midwest Center for
Environmental Science and Public Policy. He says the sewage contains pathogens –
bacteria and microorganisms – that can cause disease in humans. He’s worried about the
material spreading along the lakeshore.
“Probably accumulating at the beaches, in the sand, and in the cladophora, this algae that
washes up in the lake and rocks, and other structures that occur along the shoreline.”
The sewerage district in Foran’s home city of Milwaukee has already dumped about two
billion gallons of sewage into Lake Michigan this spring. He says the large volume of
water in the lake will dilute some of the sewage. But Foran is still expecting some beach
closings this summer.
