Description:
The Detroit River has experienced over a century of heavy contaminant discharges from industry and municipalities. The sources of contaminants vary, and include non-point sources, combined sewer overflows, point sources, tributaries, sediments, and upstream inputs. ---
Demonstrable improvements in water and sediment quality of the Detroit River have occurred during the past three decades. The long term trends of lead, copper, and zinc concentrations in the water column have exhibited distinct decreases from 1981 through the present.- - -
Data on the quality of sediments and water are essential for us to make informed decisions on remediation programs in the Detroit River. It should be apparent that more must be done. We must be able to determine the relative importance of chemical exposures from water and sediment in order to know which remedial options will give us the most benefit. - - -
