“…The COD values for monsoon (10 to 15 mg/L) has a good concordance of the previous works of Islam et al [4]. On the other hand another previous literature revealed that the maximum COD values of Ganges, Brahmaputra and confluence were 103 mg/L, 75 mg/L & 102 mg/L and minimum values were 15 mg/L, 16 mg/L & 13 mg/L [20]. Thus it indicates that the surface water in the studied area is relatively better with respect to COD compared to Ganges, Brahmaputra and confluence although does not meet the standard for drinking water.…”

“…The physico-chemical parameters values of the present study were compared with other rivers of Bangladesh (Table 4). The measured mean values of pH, DO, TDS, EC and turbidity were lower but BOD and COD were higher than the Ganges and Brahmaputra river recommended by Tareq et al (2013). According to Rahman and Huda (2012), the mean values of temperature, pH, TDS, EC, turbidity, DO were higher but BOD were lower in the Padma river than the present study.…”

“…Surface water samples were collected from 15-30 cm below the river water surface and at distances of 40-80 cm from the bank of the river in pre-labeled sample bottles which was washed with 10% HNO 3 acid and rinsed repeatedly with distilled water. Before the sample collection, sample bottles were rinsed three times with the river water (Tareq et al, 2013). For measurement of heavy metal concentration, 65% concentrated HNO 3 acid was added to each sample immediately to bring the pH blow 2 to minimize precipitation and adsorption onto container walls (APHA, 1998).…”

Abstract:The pollution of river water and sediments by heavy metals has assumed serious problems due to their toxicity and accumulative behavior. The present study has been undertaken to assess the levels of heavy metals and the extent of pollution in the surface water and sediments from the Meghna river. Water and sediment samples were collected by the Standard Methods and, processed and analyzed for heavy metals using Flame Atomic Absorption Spectrophotometer (FAAS). The mean concentrations of heavy metal found in the river water were in the order of: ). Pb and Ni were found below detection limit in river water. Based on the findings, the Meghna river water can be considered as unpolluted with respect to Cd, Cr, Mn and Zn, whereas concentration of Fe was above the standard value according to recommended standard guidelines. According to Sediment Quality Guideline (USEPA, 1989), sediments were not polluted for Cd, Pb and Zn; moderately polluted for Cr and Mn and heavily polluted for Ni. The sediment geo-accumulation index (I geo ) values showed no pollution for most of sampling sites for all studied heavy metals. Pollution Load Index (PLI) values showed that all the studied sampling sites were not polluted and on the other hand mean Contamination Factor (CF) values showed low pollution for all measured heavy metals except Ni which indicated moderate pollution. This study can be used as reference to monitor the quality of water and sediments of the Meghna river.

“…However, the rivers far from the industrial region are not such highly polluted. The DO, COD and BOD levels of Jamuna, Meghna, Podma, Mahuri, Surma, Ganges river are in the permissible level [31][32][33][34]. The permissible level of DO, COD and BOD indicates that the lower dumping of organic wastes and lower aerobic bacterial decomposition has been occurred in those rivers.…”

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.
