Over the last several years, the Broward County Department of Natural Resource Protection has identified a series of major environmental problems in the North Fork of the New River, including illegal wastewater sludge discharge and heavy metal contamination of sediments (DNRP 1993 1994). A qualitative survey suggests that benthic macroinvertebrates have been negatively affected (DNRP 1997). Restoration projects have included removal in the summer of 1997 of a remnant sludge blanket from an area of the channel east of Interstate 95 and north of Broward Boulevard. However, the effectiveness of such dredging in terms of habitat restoration has not previously been examined. This report documents the results of four sampling events carried out in order to investigate the response to such dredging of benthic macroinvertebrate assemblages in the North Fork of the New River.
