Reconstruction of sediment history in the Clinton River

~ “””the unique characteristics of the Clinton River – Lake St. Clair system
appear to allow sediments to continuously build up””””

~ “””Understanding sediment accumulation is important to reconstruct
the past pollution levels, that are generated by urbanization and
industrialization along the Clinton River, in the water and sediments.
Pollution in Clinton River sediments was recognized in the early 1970s
and is considered a threat to the public health as water from the
Clinton River empties into Lake St. Clair ~”””

~ “””over a half-century worth of sediments of significant polluted sediments
appears to be preserved below depths that have been remediated.
When these polluted sediments are stirred up by storm and boat activity,
they might be carried out to Lake St. Clair where much of the Detroit area
receives their drinking water and about a third of all Great Lakes fish are caught

Interconnected riverine-lacustrine systems as sedimentary repositories:
Case study in southeast Michigan using 210Pb and 137Cs-based sediment accumulation and mixing models
are reported by Jason Jweda and Mark Baskaran
in the latest issue (Volume 37, No. 3, pp. 432-446)
of the Journal of Great Lakes Research, published by Elsevier, 2011.

Based on data from the Michigan Department of Environmental Quality
Millions of gallons of combined sewage overflow often make it into
