dc.description.abstracta b s t r a c t In Stone Town, Zanzibar, sewage treatment is minimal, with a biological oxygen demand reduction to 60% and no removal of bacteria or nutrients. Here, Stone Town’s sewage pollution was studied by measuring Enterococci and NHþ4 concentrations in seawater and d15N of benthic organisms; samples were collected along the Stone Town shoreline and from offshore coral reefs. Public perceptions of sewage pollution were investigated via interviews. Enterococci from the Stone Town shoreline exceeded USEPA guidelines for recreational use. Benthic organisms from two of the four reefs were relatively enriched (d15N > 10‰), indicative of sewage derived N. d15N values of organisms from Stone Town exceeded 16‰. A strong correlation was found between Enterococci and d15N across sites, while step-wise regression indicated rainfall and tidal stage as important predictors for bacterial concentrations. These data provide an important impact assessment from which the efficacy of future policy and management change can be assessed. 2012 Elsevier Ltd. All rights reserveden_US
