“…In addition, both studies noted above average levels of sediment contamination in the relatively low salinity tidal flats of the upper bay, which receive large influxes of water from several large tributaries. The extent and intensity of toxic impacts to the tidal rivers of the Bay were summarized by the Chesapeake Bay Program in 1999 (U.S. EPA 1999), and later updated by additional studies focusing on sediment (Fulton et al 2007) and water column (McConnell et al 2007) chemical contamination. This evaluation classified three highly urbanized and industrialized areas near Baltimore, Washington D.C., and Norfolk as "areas of concern" and 10 regions, primarily on the more urbanized western shore of the Bay, as "areas of emphasis."…”

We examined benthic condition in three small watersheds in the Chesapeake Bay. Characterization of benthic condition was based on the combined measurements of benthic fauna, sediment toxicity, and sediment contaminant loads. Significant differences between watersheds were detected for sediment contaminant concentrations and water quality. The intensity of benthic impairment was greatest in the river surrounded by the most developed watershed. Spatial patterns of benthic condition were detected within all three watersheds. In contrast to current, intense focus on nutrient pollution in the Chesapeake Bay, qualitative comparison of our findings to land-use patterns supports findings of other studies that suggest benthic condition in tributaries of the Chesapeake Bay may more closely relate to urbanization than agricultural land uses.
