Water Quality Assessment of Shitalakhya River

Abstract

Water quality is the key of environmental concern because of its important provision of water for drinking and domestic purpose, irrigation and aquatic life including fish and fisheries. The present study was conducted to assess the surface water quality of the Shitalakhya River from January, 2017 to December, 2018. Temperature, pH, EC, TDS, TSS, BOD5, Alkalinity, Total Hardness, Calcium Hardness, Magnesium Hardness, Chloride, Dissolved Silica, Total Iron concentration and Turbidity in water samples have been found in the ranges 24 - 33°C, 6.5 - 7.6, 108 - 478 µS/cm, 54 - 245 ppm, 8 - 118 mg/l, 6 - 12 mg/l, 36.6 - 231.8 mg/l, 30 - 190 mg/l, 20 - 120 mg/l, 10 - 80 mg/l, 3.54 - 9.91 mg/l, 16 - 51 mg/l, 0.10 - 1.5 mg/l, 2.09 - 120 NTU in the year 2017 and 21 - 32.5°C, 6.7 - 7.3, 101 - 424 µS/cm, 55 - 212 ppm, 10 - 154 mg/l, 7 - 16 mg/l, 42.7 - 219.6 mg/l, 35 - 180 mg/l, 25 - 115 mg/l, 10 - 70 mg/l, 4.96 - 16.99 mg/l, 19 - 84 mg/l, 0.10 - 2.50 mg/l, 2.73 - 214 NTU in the year 2018 respectively. Obtained results of the present study area shows that most of the parameters were within the permissible limit except Turbidity, Total Suspended Solid (TSS), Dissolved Silica (SiO2) and Biological Oxygen Demand for five days (BOD5). Use of river water can pose serious problems to human health and aquatic ecosystem via biological food chain. The present research suggests special preference for better management of the river water to protect the health of aquatic ecosystem of the river.

Effect of water quality on the spatial distribution of charophytes in the Peshawar Valley, Khyber Pakhtunkhwa, Pakistan

“…They indicate that water at the surveyed sites was fresh, slightly saline, slightly alkaline and moderately saturated with oxygen. Water pH, EC, TDS, salinity and DO were within standard limits, while water temperature, ORP and resistivity showed deviations from good conditions (Wetzel 1983;Horne & Goldman 1994;Al-Badaii et al 2013;Adhena et al 2020;Alam et al 2020). The sampling season, agricultural and nutrient runoff, domestic and industrial effluents were the major causes of fluctuations in water quality parameters, similar to previous studies conducted in habitats of the Upper Indus River (Ali et al 2007;Barinova et al 2013Barinova et al , 2016.…”

Urban river pollution in Bangladesh during last 40 years: potential public health and ecological risk, present policy, and future prospects toward smart water management

“…industries situated on the riverbank area affects tremendously the quality of Sitalakhya River water (Tables 1 and 2 ). Besides, the pollutant loads were also coming from Balu River and Dhaleshwari River [ 37 , 105 , 106 , 107 ]. The drinking water treatment plant in Saidabad receives raw water from Sitalakhya River close to Demra ghat.…”

Bacterial load, multiple antibiotic-resistance patterns, and cytotoxic effects of coliform and coliform-related bacteria associated with the surface water of dhaka city

“…Saha et al (2012) showed a pH of 7.31 in Azimpur colony pond water. Alam et al (2020) reported a similar pH (6.50-7.60) in Shitalakshya River water. According to standard (De 1999), the electrical conductivity (EC) value of surface water is <350 μs/cm.…”
