“…Similar condition has been observed in case of Turag rive which flows beside the Dhaka city [9,25]. The water quality of Shitalakkha river is also unfavorable for aquatic biota due to organic pollution [10,26,27]. As a consequence of high level of organic pollution aquatic ecosystem in the surrounding rivers of Dhaka City is almost ruined [8,12,28].…”

“…Water pollution mostly occurred in developing countries as a result of miss management of industrial, municipal, hospital wastes and dumping into the water body [20][21][22]. Dissolve Oxygen (DO) and Chemical Oxygen Demand (COD) are commonly used for the determination of organic pollution level of water body [8,10]. According to the WHO, the permissible limit of DO and COD in industrial wastewater and drinking water is 4.5-6.5 mg/l and 10 mg/l, respectively [23].…”

“…DO is a conventional parameter for assessing the water quality which indicates the availability of life in water body [10]. DO provides essential direct and indirect information about water body such as, bacterial activity, photosynthesis, availability of nutrients, stratification and so on Premlata [19].…”

“…The use of this water may highly risk for sore on skin. The river Buriganga [8] Turag [9,25] Shitallakhya [10,26] and Meghna [15] are highly polluted which is indicated by higher level of COD value.…”

Environmental analysis does not become properly meaningful unless follow the standard procedure in sampling, preserving and also in analysis. This study investigates different studies on surface and groundwater pollution and discusses their findings along with impacts on environment, human health and aquatic ecosystem demolition. Fresh water is a vital need for drinking, household, agricultural and industrial use. Fresh water availability is shrinking worldwide due to imprudent use. Abound availability of fresh water in Bangladesh is now polluting due to unwise dumping of industrial, household, agricultural and municipal wastes. Water body in urban arena is severely polluted rather than rural part. The over concentration of DO, BOD, COD, EC, TDS, Cr, Cd, Pb was observed in Dhaka region. The highest arsenic concentration was found in the ground water of Lakshimpur. The main sources of pollution in industrial cities are anthropogenic sources like untreated industrial effluent and municipal wastes whereas in rural part the main sources of pollution are agricultural and naturogenic. Transboundary impact also intensifies some river water pollution. Government approved the policies, ordinance, acts and laws however, due to lack of proper implementation and monitoring water pollution problem increasing day by day.

“…Most in the cases, all over the world, urbanization and industrial development has been performed by River or sea based. Therefore, surface water is most vulnerable to pollution due to its easy accessibility for disposal of municipal, industrial and different kinds of wastewater (Islam et al, 2015). As a carrier of industrial and municipal wastage the Buriganga River has been running across the southern part of Dhaka is now going to be biologically death.…”

The hydrochemistry and pollution status of tannery effluent as well as the Buriganga River were studied. The water quality parameters namely temperature, pH, salinity, TDS, EC, DO, COD, Cr, Cd, Ni, Cu and Zn of tannery effluent were 22.8-31.5 o C, 7.4-10.6, 3920-6280 mg/l, 4680-7220 mg/l, 7070-10810 µs, 0.3-1.1 mg/l, 1020-3800 mg/l, 7.7656 mg/l, 0.0198 mg/l, 0.2070 mg/l, 0.0304 mg/l and 0.3021 mg/l, respectively whereas in water of the Buriganga River were 22.0-31.6 o C, 6.2-7.8, 69-642 mg/l, 97-871 mg/l, 146-1309 µs, 1.1-4.1 mg/l, 140-800 mg/l, 0.0306-0.2163 mg/l, 0.0018-0.0162 mg/l, 0.0663-0.2486 mg/l, 0.0112-0.0238 mg/l and 0.0878-0.2948 mg/l, respectively. According to the statistical analysis Salinity, EC, TDS, COD, Cr, Cd, Cu and Zn show positive correlations with each other and negative correlations with Temp. and DO. Ecological risk factor shows that Cr is the highest risk metal for ecosystem. The hydrochemistry has been revealed that the water is not safe for aquatic lives.
