A Study on Selected Water Quality Parameters along the River Buriganga, Bangladesh

The buriganga river system is located in the southern part ofthe north central region of bangladesh,passing through west and south of dhaka, the capital of bangladesh. the river receives wastewater fromnumerous numbers of sources along its way, which are discharged as industrial effluents, municipal sewage,household wastes, clinical wastes and oils . the purpose of this study is to investigate into the impact of thiswastewater on the river water and thus to provide an updated report on the state of water quality of the riverburiganga. the water samples were collected in year 2008-09 during both dry and wet seasons from differentpoints along the river and analysed for various phys iochemical quality parameters, which includes: temperature,ph, ec, do, bods, cod, po.-p, nh3-n, pb and cr. the mean values for the parameters in both dry and wetseasons were compared with the surface water quality standards as set by the department of environment(doe) in bangladesh. the water quality test results have also been summarised and pre sented through box andwhisker plots.
