Overview

Sources of Pollution

While water quality problems and public use restrictions are most severe in the AOC, water resources in the entire basin are affected by runoff pollution from urban and rural areas, municipal and industrial wastewater discharges and degraded habitats. Industrialization was a major factor in Lower Green Bay/Fox River becoming contaminated.

Land water use upstream (logging, agriculture and industry) was a significant contributor to the numerous negative impacts to water quality in the water system. High turbidity, sedimentation, fluctuating dissolved oxygen, frequent algal blooms, degraded fish/wildlife/plant populations and adverse toxicant impacts have all been found in Lower Green Bay/Fox River. PCBs are the primary contaminant. The AOC is a shallow environment that has a rapid recycling system which also contributes to water quality issues.
