Abstract/ Executive Summary:

This study deals with the investigation of water quality of the Buriganga river, Dhaka. For this purpose, samples were collected from five locations of the Buriganga river of Bangladesh during wet (monsoon) and dry (winter) season in 2011 to determine the spatial distribution and temporal variation of various water quality parameters. Water samples were collected from three different depths of river. The color was light brown in wet season and slightly black to black color in dry season. The water was found slightly acidic to slightly alkaline (6.6-7.5). Water temperature ranged from 18.2o C (dry) to 27.04 o C (wet). The river was found to be highly turbid both in dry and wet season. Biochemical Oxygen Demand (BOD), Electric Conductivity (EC) and Total Dissolved Solids (TDS) were found higher in the dry season compared to that of wet season, while Dissolved Oxygen (DO) was found higher in wet season. The mean values of parameters were EC: wet- 1685 μs/cm, dry-2250 μs/cm; DO: wet- 4.9 mg/L, dry- 3.7 mg/L; BOD: wet- 26.4 mg/L, dry- 33.4 mg/L; TDS: wet-238 mg/L, dry- 579 mg/L; transparency: wet- 24.6 cm, dry- 22.8 cm.

Location: Buriganga River, Dhaka

Start Date: 00-07-2011

End Date: 00-12-2011

Program Area: Crop-Soil-Water Management

Commodity: Water quality

Objectives:

1. The present experiment was to investigate some water quality parameters of the Buriganga river and to determine their suitability for fisheries and other aquatic flora and fauna.

Methodology:

Sampling sites - The water sample was collected from different points of Buriganga river. The sampling sites were Lalkoti Ghat, Wise Ghat, Postogola launch Ghat, Badamtoli Ghat, Babubazar Ghat. These sites were chosen because these sites are heavily polluted by different kinds of waste discharged from tannery industry, commercial sectors and households. Sample Collection - Water samples were collected in wet season (July, 2011) and dry season (December, 2011). Three water samples of approximately 300 ml was collected in 500 ml plastic bottles from three different depths viz. Surface, middle, bottom of each location. After sampling the bottles were screwed and marked with the respective identification number. Sample analyses - Different methods and/or instruments were used for the determination of different physico-chemical properties of water samples.

Achievement/Findings:

Rampant disposal of municipal and industrial wastes is polluting the water of Buriganga river. With the pollution of water bodies by chemical and organic wastes the oxygen concentration in this water body becomes very low at some locations of the river. The pollution of water leads to either death or migration of fishes living there to some other places. As a result, fish population in this river has drastically decreased in recent times. The pollution problem cannot be solved in a short period. Thus, it needs to continuous efforts to control the pollution problem.
