摘要：The present study mainly focused on trend of the drinking water quality of one of the heritage city of India, Howrah. The ground water from ten stations was analysed for two consecutive years. Water Quality Index (WQI) based on physicochemical parameters put the drinking water into “nearing to poor” in 2012 and “excellent” in 2013. But the high concentration of total and fecal coliform makes the water unsafe for drinking in both years. Alkalinity, Chloride, Total Dissolved Solids (TDS) and Nitrate concentrations in some stations were found above the drinking water standards.
