“…Therefore, it is considered that the concentration of Fe was safe in almost all of the collected water samples. A recent report from the coastal Khulna district showed that the DTW of Koyra, Dacope, and Batiaghata contained a relatively high concentration of Fe [21,70]. The STW contained 3.1 ± 0.64 mg L −1 Fe, and the DTW contained 2.23 ± 5.72 mg L −1 Fe in Rajshahi city in Bangladesh [82].…”

“…These results imply that the EC of the water samples varies from location to location and depth to depth and may be related to other factors, e.g., embankments and cyclones. Generally, GW containing EC values lower than 1000.0 µS cm −1 is considered freshwater, values higher than 1000.0 µS cm −1 and less than 10,000.0 µS cm −1 are believed to be brackish water, values higher than 100,000.0 µS cm −1 and lower than 35,000.0 µS cm −1 are considered saline water, and values higher than 35,000.0 µS cm −1 are considered hypersaline [70,77]. From this result, it is clear that, in spite of being a coastal district, the DTW water of Bhola is not saline; rather, it is suitable for drinking, and this shows the individuality of this research.…”

“…Sodium (Na), potassium (K), calcium (Ca), and magnesium (Mg): The Na concentration of the GW varied from 25.0 to 85.0 mg L −1 in the BSU and CFU (Table 3). The BNDWQS and WHO recommended concentration of Na in drinking water is 200.0 mg L −1 [68][69][70]. Again, the lowest K concentration was 5.0 mg L −1 , and the highest value was 20.0 mg L −1 (Table 3).…”

The composition of groundwater governs the drinking and irrigation water suitability. A large part of the coastal region of Bangladesh is affected and is responsible for changing the composition of the groundwater. This research attempted to observe the groundwater quality of the Bhola Sadar and Char Fasson upazilas in coastal Bangladesh. Twenty-eight (28) water samples, 27 at depths of 260–430 m (850–1400 ft) and 1 from a crop field, were collected and analyzed. The quality of water samples was determined through the evaluation of odor, color, turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), ammonium (NH4+), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) and arsenic (As) ions. An Atomic Absorption Spectrophotometer was used for heavy metal analysis. The outcomes were compared with the drinking water quality of Bangladesh and the World Health Organization. The results showed that the average values of nearly all of the parameters were underneath or within the standard level, representing that the groundwater was appropriate for drinking purposes. The water quality parameters were also compared with the irrigation water quality of Bangladesh and the Food and Agriculture Organization. It was found that the collected samples were also suitable for irrigation. To do this, the soluble sodium percentage, sodium adsorption ratio, magnesium adsorption ratio, Kelley’s ratio, and total hardness were calculated. The novelty of this research is that, despite being in a coastal district, the deep aquifer water of Bhola was appropriate for drinking and irrigation purposes.

The groundwater quality of the Gopalganj district in Bangladesh was not well documented. Therefore, this research was done to determine the groundwater quality in the study area. The water quality index and the human health risk for heavy metal ingestion were used to describe the water quality. The water quality was performed through the estimation of turbidity, pH, electrical conductivity, total dissolved solids, and concentration of sodium, potassium, ammonium, nitrate, iron, manganese, zinc, copper, and arsenic. The mean turbidity, pH, and total dissolved solids in the two upazila were within the permissible limit. However, the electrical conductivity in both the upazila was higher than the WHO-prescribed value in which the higher concentration was in Kotalipara. Excess concentrations of iron and arsenic were found in the Kashiani upazila, but these were below the detection limit in Kotalipara upazila. The water quality index revealed that roughly 61.0% of samples of Kashiani upazila were of poor quality. However, about 96.0% of samples of Kotalipara upazila were of excellent quality. Chronic health risks due to the revelation of drinking have also been determined by assessing the hazard quotient and hazard index. In Kashiani, almost 85.0% of samples were elevated chronic risks for adults and 100.0% of the samples were very high chronic risks for children. In Kotalipara, all the samples (almost 100%) were suggested to have a lower chronic risk for adults and children. The results suggested that the carcinogenic risk of arsenic via oral exposure was very high for both adults and children in Kashiani upazila.
