Bangladesh relies mainly on groundwater for irrigation and drinking purposes. Groundwater, however, continuously polluted, is a major obstacle. Nowadays, Bangladesh is moving towards industrial revolution in a considerable speed. As part of this paper's attempt to analyze the groundwater pollution scenario in Bangladesh, specifically in the past two decades, about 100 articles, conference papers, and reports published in national and international journals and books were reviewed, as well as issues concerning pollution sources, health impact assessment, and future perspectives were discussed. The groundwater is contaminated by different contaminants, such as physico-chemicals, trace metals, and microbes. Human health is at great risk from arsenic (As) contamination; it is one of the biggest threats. The cancer risk and non-cancer risk of ingesting water are increased. On the other hand, a large number of peoples were affected due to waterborne diseases governed by microbial contamination. Geophysical and anthropogenic sources, the depth of wells, and geographical factors may influence groundwater pollution. It is recommended that policy makers should address the issue immediately and precautions should be taken wherever necessary.

Groundwater is one of the most important freshwater sources in Bangladesh which is used for drinking, household chores and irrigation. Due to high population pressure and excessive withdrawal, this important resource is under a lot of pressure. This study is designed to assess the present groundwater condition of the entire eastern region of Bangladesh. Groundwater depth data of 271 wells from 21 districts were collected from Bangladesh Water Development Board (BWDB) and analyzed in ArcGIS and Microsoft Excel software. During the pre-monsoon period, the groundwater lies beneath 2 to 14 meters of sediment. In the dry season, the groundwater remains between 4 and 12 meters in the northeastern part of Bangladesh. The larger values are mostly associated with urban areas. In case of southeastern part, groundwater level ranges from 2 to 8 meters. But the urbanized areas have groundwater levels in ranges in between 6 and 12. Compared to northern part, groundwater is found closer to surface in the southern part of the study area, Comilla, Mymensingh and Kishorganj. During monsoon season, there is a wide disparity of groundwater condition in the northeastern part, but southeaster part shows homogeneity. So, significant variation in groundwater depth (seasonal as well as spatial) is seen throughout the study area. The impact of urbanization is seen clearly which leads to lowering of groundwater level that can cause catastrophic events like earthquake, subsidence and pollution.

The groundwater pollution by arsenic in Bangladesh causes a serious problem for millions of people who are exposed to poisoning by this toxic element. In an attempt to evaluate the extent of arsenic poisoning, hair samples of people living in Pabna district were collected. The hair samples were analyzed using Proton Induced X-ray Emission (PIXE) through exciting the atoms of a specimen so that their intensities can be converted into elemental concentrations in the specimen. The elements present in the specimen are identified by the corresponding X-ray energies and their concentrations are deduced from the X-ray intensities. The results from hair samples indicate substantially higher level of arsenic than those demarcated as toxic levels, in people from member families both affected and non-affected by poisoning. We correlate it with exceedingly high arsenic concentration in drinking water far above the permissible limit. The analytical results are compared with the results of arsenic and other elemental analysis of 160 Bangladeshi hair samples with that of 250 Japanese samples. The results show markedly higher levels of arsenic, manganese, iron and lead where the latter three elements show a positive relation with arsenic in the case of Bangladeshi as compared to the samples from Japan. On the other hand, selenium concentrations show very low level in the Bangladeshi samples compared to Japanese, displaying an inverse relationship with arsenic. The mechanism of arsenic in relation to other elements in the human body needs further investigation. The preliminary results call for detailed experimental and epidemiological studies to further characterize these aspects.

Bangladesh is one of the fastest growing economies in the world, primarily driven by its textile industries. A high amount of water is consumed and polluted in the production and processing of raw material to the final product in the textile industry. Therefore, water footprint assessment is important for textile products. In this study, the water footprint of cotton cultivation, transportation and textile industry was calculated by analyzing the amount of imported cotton, production and processing capacity of cotton yarn and cotton fabrics, wastewater volume, number of workers and pollution load database, for 2012–2016. For the textile industry, the annual water footprint was found to be 1.8 billion m3. This high amount of water footprint and water pollution may result in depletion of groundwater level and can lead to major health problems for the local people, respectively. Total water footprint for ready-made garment product is found to be 27.56 billion m3, whereas considering proper water treatment and water reuse facilities can reduce the grey water footprint to around 1.26 billion m3. This study shows the extent of water pollution, groundwater depletion and economic impact of groundwater extraction, and possible means to reduce water footprint in cotton cultivation and textile industries.

Annotation:
People in the southwestern (SW) coastal part of Bangladesh are suffering from a severe freshwater crisis due to saline groundwater at a shallow depth. Fresh groundwater below a 200 m depth is an option, but it is costly to construct deep tubewells for the local inhabitants. The processes of salinization and freshening were previously identified using conventional methods. In this study, we brought new insight into these processes by analyzing existing datasets using multivariate statistics to identify the factors affecting groundwater chemistry. Cluster analysis (CA) revealed three major clusters. Cluster A corresponded to saline (NaCl-type) water. Cluster B was also saline (NaCl-type) water but showed mixing effects. Cluster C was fresh groundwater (NaHCO3-type) and isolated. The hydrochemical characteristics of clusters A, B and C compared remarkably well with the groundwaters from the upper shallow aquifer (USA), lower shallow aquifer (LSA) and deep aquifer (DA), respectively. Factor analysis (FA) showed that 75% of the total variance was influenced by evaporate dissolution, carbonate dissolution/precipitation, cation exchange and anthropogenic pollution to some extent. Therefore, the integrated approach showed the validity of applying multivariate statistical techniques to infer the dominant hydrochemistry and to characterize and understand a complicated hydrogeological system.
