Abstract

The St. Louis River estuary contains a diverse set of habitats with both relatively pristine as well as impacted regions. Benthic communities within the estuary are of special concern due to impaired conditions in some areas (St. Louis River System Remedial Action Plan, 1992). These communities play a large role in detrital decomposition, nutrient cycling, and provide an important food source for fish. Benthic macroinvertebrate communities have been used extensively for monitoring environmental condition for many years and can be good indicators of sediment quality (Rosenberg and Resh 1993). This study examined benthic communities in the vicinity of two US EPA superfund sites adjacent to the St. Louis River Estuary. The study was limited to descriptive analysis of existing communities in embayments near the superfund sites.
