Faecal pollution of freshwater environments in Bangladesh

Abstract
The sanitary quality of any water source is conventionally measured by estimating the concentration of faecal coliform bacteria. An investigation was carried out over 12 months to determine the faecal pollution of 5 ponds in and around Dhaka city from May 1988 to April 1989. The results showed that four of the 5 studied ponds, were heavily polluted by faecal matter. These data suggested that these ponds are potential sources of health hazards which is important from a public health point of view.
