The presence of pesticides and particularly the chlorinated hydrocarbon
insecticides in Lake Michigan water is responsible for biological
accumulations that affect a wide variety of legitimate uses. The data
collected from waters, wastewaters, invertebrate organisms and fish all
suggest that DDT plus analogs and dieldrin are observed consistently at
levels that warrant concern from both a public health and wildlife
preservation standpoint. The sources of these chlorinated hydrocarbon
insecticides include not only industrial and wastewater effluents but
also diffuse sources such as from agricultural activities and municipal
pest control programs.
The evaluation of the chlorinated hydrocarbon insecticides in both
wastewater and biological specimens is complicated by the presence of
products such as polychlorinated biphenyls and phthalates. These
products interfere with the analysis for the target insecticide and,
indeed, have biological implications of their own.
This report is submitted in fulfillment of four cooperative grants to
the Lake Michigan Enforcement Conference participating state under the
sponsorship of the Environmental Protection Agency and include grant
numbers 16050 EYV (Wisconsin), 16050 EYS (Indiana), 16050 EFV (Michigan)
and 16050 ESP (Illinois) for an investigation of "Evaluation of Pesticide
Sources and Levels Tributary to lake Michigan".
