“…Several researchers had carried out extensive studies on water quality of the Tista floodplain. Islam et al (2017) studied the trace element contents of Rangpur district and concluded that the trace element quality of groundwater is mainly related to natural/geogenic sources followed by anthropogenic sources. Salinity with increasing depth has been reported in lower Tista floodplain which is an indicative of mixing of fresh and saline bodies due to marine transgression during Holocene period in the Bengal delta (Afroza et al 2009).…”

The Tista is a Trans-Himalayan river that flows through Sikkim and West Bengal states of India and Rangpur division of Bangladesh and finally falls into the Brahmaputra River. The presence of numerous abandoned channels with various degrees of aggradations indicates large migrations of the Tista River. The pH value of groundwater varies from 6.20 to 7.40 which indicate the slightly alkaline to acidic nature of the studied aquifers. The mean abundance of major cations is Na + > Ca +2 > Mg +2 > K + , whereas the major anions is HCO 3 − > Cl − > SO 4 −2. Among the cations, Na + is the dominant and K + is the lowest constituents, whereas HCO 3 − is most abundant and SO 4 −2 is the minor constituents in anions. The hydrochemical facies of groundwater show that sodium, sodium-magnesium, sodium-calcium, sodium-magnesium-calcium and sodium-calcium-magnesium are cation facies and chloride-bicarbonate, bicarbonate-chloride and bicarbonate are anion facies. Correlating with WHO (Guidelines for drinking-water quality, 1, World Health Organisation, Geneva, 1997) and EQS (Environmental quality standard, Department of Environment, Bangladesh, 1989) guideline values for drinking water and public health, it may be concluded that the groundwater of the study area is suitable for all drinking and domestic purposes, where only three samples exceed the maximum allowable limit of potassium. Based on total hardness, SAR, RSC, PI, SSP and MH values, it can be summarized that the groundwater of the investigated area is suitable for irrigation purpose. On the basis of Australian and UNESCO standard, the groundwater of the study area is also suitable for livestock purposes. The Rangpur area is hydrogeologically active by the processes like ion exchange and dissolution. Ca 2+ , Mg 2+ and HCO 3 − are produced by the dissolution of limestone and dolomite.

“…3). This might be due to the over-mining of groundwater, cation exchange, excess weathering of carbonate rock, and dissolution of carbonic acid (Mostafa et al 2017;Islam et al 2017b;Chegbele et al 2020). Lower river-ow and overexploitation of groundwater are the main cause of the over-loading of the abovementioned ions.…”

Groundwater is a vital source of irrigation water, and it provides over 80% of the irrigated water supply in Bangladesh. The study aimed to assess the status of irrigation water of the Ganges river basin areas in the middle-west part of Bangladesh through the hydrogeochemical characterization and classification of groundwater. The study parameters were pH, EC, TDS, Ca2+, Mg2+, total hardness, Na+, K+, B, Cl−, HCO3 −, SO 42−, NO3 −, and PO43− along with irrigation water quality index (IWQindex), Na%, soluble sodium percentage, sodium adsorption ratio, residual sodium bicarbonate, magnesium adsorption ratio, permeability index, and Kelley’s ratio. The results showed that most of the water samples were acidic in the pre-monsoon and alkaline in the post-monsoon seasons, and the water type was Ca-HCO3. The significant geochemical process in the area determined was calcite and dolomite mineral dissolution, and there was no active cation exchange, and silicate weathering occurred. The statistical analyses showed that both the geogenic and anthropogenic sources were controlling the chemistry of the groundwater aquifers. Concerning irrigation water quality, the results revealed that all the quality parameters and IWQindex (32.04 to 45.39) were within the safety ranges, except for the EC and total hardness. The study results would be useful for future groundwater monitoring and management of the Ganges basin areas of Bangladesh part.

“…Stations of cluster 2, situated in the downstream region, accounted for the highest accretive concentration of the elements owing to some specific industrial stresses such as sand scavenging activities, and industrial effluents from paper cement, chemical, fertilizer, shipping, and oil industries, as well as nearby fervent power stations, etc. [16,55]. The consistency of the trace element concentrations in the contiguous stations might be ascribed to the potential unidentified point sources coupled with limited radiating impact downstream of the river.…”

“…To date, few studies have been conducted to assess the Karnaphuli River water quality. Therefore, water pollution studies need to check whether the use of this polluted water has any health effect on people [14][15][16]. In this study, health risk assessment was performed according to different pathways based on USEPA guidelines [17].…”

Health Risk and Water Quality Assessment of Surface Water in an Urban River of Bangladesh

Despite significant contributions to the national economy of Bangladesh, various urban developments, massive industrial and growing shipping activities are making the water of many urban rivers, including Karnaphuli River, extremely polluted. To find out the pollution sources and their possible health effects, 45 water samples were collected from 15 sampling stations. Investigation of six physicochemical parameters (pH, temperature, total dissolved solids, conductivity, salinity, and turbidity) through in-situ measurements and eight heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) status using atomic absorption spectrophotometer (AAS) was carried out in this research. Both the physicochemical parameters and heavy metals exceeded the World Health Organization (WHO)’s permeable threshold limit. The calculated hazard quotient (HQ) and hazard index (HI) ingestion values indicate non-carcinogenic risk both for adults and children, but dermal exposure was within the safety limit. Carcinogenic risk analysis revealed that Cd could cause a risk of cancer in those using the river water for a long period. Spatial analysis and metal pollution index (MPI) results exhibit that downstream of the river water is more polluted than upstream of the river. Overall, the findings of this study imply that polluted water is a threat to human health and the results will also help to undertake proper management strategies and incorporate monitoring programs that study river water for the implementation of safety measures to protect human health.
