In a Metropolitan city like Mumbai in India safe, consistent, and reliable water supply is a challenging task. Large number of population lives in areas of Mumbai that are suffering from water quality problems and water shortages which is also studied by our institution in a community-based project CAASP (Community Assessment Awareness Survey Program).Many areas have contaminated water with fecal Coliforms bacteria as the primary contaminant of concern. There are many aid groups that are actively working to develop and improve the water supply in the developing world. An important first step in such work is an accurate appraisal of the existing water supply. This appraisal often requires a rapid, onsite field assessment of possible fecal Coliforms contamination with minimal equipment. Therefore, Department of Biotechnology and Department of Botany of R.D. & S.H. National College have initiated a community-based project to evaluate the potability of water from different location of Mumbai by MPN (Most Probable Number) method since year 2009-10. This project also aims to provide guidance to the citizen of Mumbai through our institution about the usability and importance of water testing.
