Abstract:
ABSTRACT
Water is known as the most important and major requirement for life and life supporting
activities. The usual source of drinking water from streams, rivers, wells are usually not
treated. Present study was conducted to assess some physio-chemical properties of water
collected from different point of Chunkuri, Dhaki and Vodra rivers of Bangladesh. To
reach the goal of our study total 21 samples were collected from the three rivers
randomly to analyze the physio-chemical properties: Color, Odor, pH, Total Dissolved
Solids (TDS), EC, Turbidity, Chlorine, DO and BOD5. Results from our study showed
that most of the parameters did not exceed the maximum permissible limit except
Turbidity. Study revealed that pH: 7.99, 8.03 and 7.99; TDS: 270.17, 265 and 326.17

for Chunkuri, Dhaki and Vodra rivers respectively. The average
turbidity of Chunkuri, Dhaki and Vodra rivers were 16.58, 38.42 and 64.51 NTU, where
standard Turbidity is 5 NTU but ideal is 1 NTU. Water color were black, ash and light
grey with foul odor driven by huge contaminant factors. Proper embankment plantations,
riparian management in the watersheds can help to improve the water quality of these
rivers.
