The Golden Horn Estuary is an ecologically sensitive recreational area located in the urban center of Istanbul. This study aims to (1) determine the impact of dry and wet weather conditions on fecal indicator bacteria (FIB) concentrations and (2) to evaluate the microbial water quality in the last decade. Our results revealed that precipitation negatively influenced microbial water quality by significantly increasing FIB concentrations (about 1 log MPN/100 mL) in the Golden Horn. The FIB loads from creeks and combined sewer overflows are the primary contributors to the Golden Horn's microbial contamination. Despite the rehabilitation efforts, no substantial improvement in microbial water quality has been observed in the last decade. In conclusion, the Golden Horn Estuary faces a pressing need for improved microbial water quality. By addressing the identified pollution sources, implementing effective wastewater management strategies, and enhancing public awareness, the Golden Horn can potentially be transformed into a healthier and more sustainable ecosystem.
