“…The highest mean concentration of Mn in groundwater was found in the water sample of the tubewell water in Singair, Manikgonj (Halim et al., 2014). An elevated level of Mn was found in shallow tubewell (1.87 mg/L) in Cox's Bazar area; the deep water sample collected from the same area also showed a significant presence of Mn due to high rock-groundwater interaction (Seddique et al., 2016). A study conducted in Greece reported that individuals who consumed drinking water containing more than 1.8 mg/L Mn, exhibited neurologic symptoms which are similar to Parkinson's disease (Kondakis et al., 1989).…”

Bangladesh – one of the most densely populated countries of the world— has plentiful water sources, but these sources are being polluted continuously. Both surface water and groundwater sources are contaminated with different contaminants like toxic trace metals, coliforms as well as other organic and inorganic pollutants. As most of the population uses these water sources, especially groundwater sources which contain an elevated amount of arsenic throughout the country; health risk regarding consuming water is very high. Death due to water-borne diseases is widespread in Bangladesh, particularly among children. Anthropogenic sources such as untreated industrial effluents, improper disposal of domestic waste, agricultural runoffs are the main contributors regarding water pollution. A total water pollution status of this country, as well as the sources of this severe condition, is crucial to evaluate public health risk. For this purpose, we reviewed hundreds of well recognized international and national journals, conference proceedings and other related documents to draw a complete picture of recent water pollution status and its impact on public health; also the sources of water pollution are identified.

“…The upper unconfined aquifer is composed of fine to medium sand having thickness of 5 to 15 m followed by the middle semi-confined aquifer at depth 30 to 80 m with the same lithology. The thickness of the middle aquifer ranges from 15 to 50 m. The lower confined aquifer exists at the depth of more than 80 m which shows fine to medium sand composition [30].…”

Groundwater provides the largest source of usable water storage in Bangladesh. Groundwater samples have been analyzed for Fe, Mn, Zn, Ni, Cr, Cu, Cd, Pb, and Co using atomic absorption spectrophotometer to evaluate the heavy metal distribution and contamination level at the southeastern coastal area of Bangladesh. Heavy metals in water samples are in the range of Fe (490-4710 µg/L), Mn (13-1970 µg/L), Zn (70-550 µg/L), Ni (42-255 µg/L), Cr (25-133 µg/L), Cu (34-95 µg/L), Cd (7-26 µg/L), Pb (0-20 µg/L), and Co (43-141 µg/L). The mean concentration of Cr, Cd, Fe, Mn, and Ni exceeded the Bangladesh standards for drinking water. Application of Pearson correlation, principal component analysis (PCA), cluster analysis (CA) and hierarchical cluster analysis (HCA) indicate that groundwater of the study area are influenced by both geogenic and anthropogenic sources of the heavy metals. Heavy metal evaluation index (HEI), degree of contamination (C d ) and heavy metal pollution index (HPI) are employed to evaluate the overall pollution level of groundwater estimating 40, 27 and 60% of samples respectively and exhibit the medium degree of pollution.

Hydrochemical study of groundwater in the aquifer system of the southeast coastal area of Bangladesh was carried out to investigate the processes of groundwater hydrochemistry as well as the suitability of groundwater for drinking purposes. Water samples from tube wells (depths 6.5–165 m) were collected and examined several water quality parameters to describe the hydrogeochemical characteristic. Most of the water samples were found as fresh and soft water with few numbers of hard and brackish water. The overall sequence of cation and anion throughout the study area are Ca2+> Na+> Mg2+> K+ and HCO3−> CO3−> NO3−> SO42−> Cl− respectively. Maximum water quality parameters satisfy the drinking water quality standard proposed by WHO. Piper diagram suggests that Ca2+- Mg2+- HCO3− (80%) and Ca2+- Na+- HCO3− (20%) facies are the predominant water type. Gibb’s plot implies a rock dominant inheritance that regulates the groundwater chemistry. The most significant hydrochemical processes in the study area are carbonate weathering and cation exchange. Correlation analysis recommends that TDS, EC, Na+, Ca2+, Cl− and SO42− are strongly correlated with each other, indicating their contribution to water mineralization. The principal component analysis (PCA) and Cluster analysis shows weathering and leaching of parent rocks are the leading environmental sources, while intensive farming incorporating the extensive use of pesticides and fertilizers might be another anthropogenic component that influences the groundwater hydrochemistry.
