title: GIS based water quality indexing of Malad creek, Mumbai (India): an impact of sewage discharges.
abstract: Malad creek is one of the most heavily polluted water bodies in Mumbai, India. Presently, creek receives wastewater and sewage from open drains and nallahs as well as partially treated wastewater from treatment facilities. The objective of the present study was to assess and classify the water quality zones spatially and temporally based on physico-chemical and bacteriological analysis. For this, GIS based methodology was integrated with water quality indexing, according to National Sanitation Foundation. Nine water quality parameters were considered to generate the indices that represent the overall status of creek water quality. Based on field observations and spatial distribution of water quality, various options were suggested for improvement in water quality of the creek.
