Water is the most important thing for the survival of human beings because man cannot live without water for a single moment. The coastal region of Bangladesh faces pure drinking water crisis due to saline water intrusion and iron content of tube wells where pond sand filter (PSF) is using as alternative water supply system of southwestern coastal region specially Sudarban region of Bangladesh. This study was conducted to assess the quality of water and evaluate and compare the performance of these technologies at Mongla Upazila of Bagerhat District. For this purpose 24 water samples from six PSFs, eight protected pond (PP) and two reverse osmosis (RO) were collected and analyzed in the pre monsoon season. Different physico-chemical and biological parameters such as pH, electrical conductivity (EC), total dissolved solid (TDS), salinity, turbidity, ammonium (NH4+), total hardness, total alkalinity, Chloride (Cl-), total coliform and fecal coliform were measured both in PSFs and PP water.
