Chemicals in the Clinton River
The Clinton River shows signs of pesticides, herbicides,
insecticides and fungicides potentially threatening insects and fish.
An article by Eric Freedman in The Great Lakes Echo, December 4, 2014
describes research done on Michigan’s urban streams and rivers.
Michigan State University’s Kellogg Biological Station
assisted in the study by the USGS and Department of the Interior.
Rain runoff from golf courses combined with hundreds of thousands
residential homes using “pest control” and numerous industrial parks
using fertilization services; contribute to chemicals in the rivers.
Herbicides applied directly to lakes for control of aquatic plants
also enter into the Clinton River.
It is a cumulative effect, from numerous sources, adding up quickly,
for a total; that monitoring equipment easily detects.
The catch, there are hundreds of different chemicals being used ,
and funding to monitor everywhere, all the time, just does not exist.
The Geological Survey said, “One or more pesticide compounds were
almost always present at detectable levels in stream water.”
The findings are based on tests from 1992 to 2011.
“There were detectable concentrations in water more than
90 percent of the time across all streams sampled that had significant
agricultural or urban land use in their watersheds,” it said.
