Abstract
Anthropogenic activities like the release of domestic and industrial effluent, deforestation of mangroves, and reclamation of land have severely damaged coastal ecosystems, leading to ecological degradation. Panvel Creek in the Navi Mumbai region of Maharashtra is affected by residential, commercial, and industrial expansion. The Taloja MIDC zone and nearby sewage treatment plants contribute to the deterioration of water quality. The present study aims to study the pollution status of Panvel Creek. Water samples were analysed for physical and chemical properties, and changes in water quality were mapped using GIS software. During the present study, the average temperature was observed to range between 30 °C and 36 °C. Water samples had pH values ranging from 6.33 to 8.06, dissolved oxygen levels ranging from 2mg/ l â6 mg/l, and nitrate concentrations ranging from 1.47 mg/l - 20.30 mg/l. Phosphate levels were high in all locations except near the mouth of Panvel Creek, with the lowest value being 11.93 mg/l. Over the years, various developmental activities within the Navi Mumbai region have exerted anthropogenic pressure on the ecology of the creek.
