“…It might be a result of Na dissolution from lithogenic minerals and cation exchange between aquifer geochemistry and groundwater [ 95 ]. The average concentration of Na + in the groundwater of the study domain is also comparable with the findings of [ 96 , 97 ] ( Table S2 ).…”

“…Another geogenic reason for high nitrate concentrations in the studied areas could be a poor soil profile. Anthropogenic sources of high nitrate concentrations in the groundwater of the studied area were animal and human waste, high cropping, aquaculture practices, and an unmanaged irrigation system [13]. The high levels of nitrate in the groundwater of Manikganj (253.18 mg/L) and Satkhira (54.44 mg/L) could be caused by extensive agricultural practices and the widespread use of unplanned latrines and septic tanks that allow their contents to leak into the soil and then into the groundwater [75,76].…”

“…Literature studies revealed that the groundwater of the central districts (e.g., Manikganj), south-west district (e.g., Satkhira), south-central district (e.g., Jessore, Gopalganj), south district (e.g., Barishal, Bagerhat, Barguna, Patuakhali, Pirojpur), south-west district (Chandpur), central-west district (Pabna), western district (Rajshahi, Naogaon), north-western district (e.g., Thakurgaon), northern district (Kurigram, Gaibandha), and north-eastern district (Sunamganj) were high to moderately loaded with nitrate concentrations. The child population in these districts was considered to be more susceptible to groundwater nitrate-induced health hazards [10][11][12][13][14].…”

Access to safe potable water is one of the most significant challenges in an environmentally vulnerable country like Bangladesh. The presence of high concentrations of nitrate in groundwater can deteriorate its quality and pose serious health threats. A review was conducted to evaluate the current status of overall nitrate concentrations in different districts (35 out of 64 districts) of Bangladesh based on available published data. Human Health Risk Analysis (HHRA) and nitrate pollution index (NPI) were calculated to illustrate the level of chronic risk and degree of pollution among the population of the studied districts. The HHRA model predicted that the adult population of 48.57% districts and the child population of 56.25% districts were found to be facing potential health risks associated with elevated nitrate consumption. The NPI results revealed that at least 45.72% of the studied districts were characterized by light to very significant nitrate pollution loads. It can be concluded that the outcomes of this systematic study would draw the attention of policymakers and the population of all districts and enable them to take effective measures in preserve groundwater resources in Bangladesh and prevent long-term, complex diseases.

“…Natural disasters such as rising sea levels due to climate change can move saltwater into the freshwater aquifers through river networks connected with the Bay of Bengal [9]. Saltwater intrusion into coastal aquifers can be caused by anthropogenic reasons, such as the over-extraction of groundwater to meet daily demands for industrial or agricultural purposes [10]. Due to such human activities and naturally induced phenomena, the balance between the freshwater and saline water interface is differentiated in the coastal regions.…”

This study aimed to develop a geochemical database by thoroughly analyzing groundwater and sediments from coastal aquifers of southwest Bangladesh. Moreover, we investigated the source of sediment deposition and the mechanisms behind the presence of arsenic and salinity in groundwater. The seasonal distribution patterns of arsenic among the shallow and deep coastal aquifers were found to be 45.12 µg/l and 20.65 µg/l during dry and wet seasons, respectively. Moreover, the groundwater salinity distribution ranged from 3262.88 mg/l to 1930.88 mg/l during the dry and wet seasons. Cored sediment samples showed fine to medium sands of 92%, with silt and clay particles. The petrographic study of authigenic and heavy minerals revealed that the mineral grains were subangular to angular, indicating their textural immaturity of coastal sediments. The reactivity of goethite (FeOOH) and siderite (FeCO3) minerals suggests that the aquifers were subjected to slightly oxidized to moderately reducing conditions, with ORP values ranging from +50.40 mv to −149.5 mv. Such redox conditions could potentially result in the enrichment and mobility of arsenic in the groundwater. Although arsenic concentrations in deep aquifers are relatively low, higher salinity values are found in both shallow and intermediate coastal aquifers.
