Title: A report on the infaunal communities within Weston Bay in relation to the sewage outfall at Black Rock
Author: Mitch Perkins
Document Type: Monograph
Abstract:
The aim of this study was to establish whether sewage effluent discharged from the outfall at Black Rock, was having an impact on invertebrate communities within Weston Bay. The outfall receives effluent from the Black Rock Pumping Station, which serves up to 100,000 residents and visitors to Weston-Super-Mare. Screened effluent, which is discharged from the outfall into a channel formed by the River Axe, is disinfected during the summer bathing season to ensure that local beaches do not fail the European Communities Bathing Water Directive. During November 1991 and January 1992, a total of 48 sites from intertidal and subtidal areas of Weston Bay were sampled. These samples were examined for benthic infauna and analysed for organic carbon and nitrogen content, and sediment particle size. Multivariate techniques were used to reveal patterns in faunal distribution, and help explain if any of the environmental parameters examined could be influencing the faunal assemblages present within the bay.
