“…It might also be because of the contact between rock and water and agricultural activities (Abbasnia et al 2019). An average value of 1043 mg/l TDS in Khulna (Adhikary et al 2012) and an average value of 1556.05 mg/l (Islam et al 2017) in the groundwater of the coastal aquifer of Khulna city were also reported. Percolation of elements from rocks and gypsum rocks might be another reason for high EC and TDS in the water.…”

“…The latitude and longitude of the city are 22° 46′ to 22° 58′ North and 89° 28′ to 89° 37′ East, respectively. The city is located on a riverine area where the tidal river Rupsa crosses the middle part of the city, the river Bhairab is on the northern, the Pasur river is on the southern side, and the Mayur river is located in the western area of the city (Adhikary et al 2012;Roy et al 2005).…”

“…It might also be because of the interaction of rock and water and agricultural activities (Abbasnia et al 2019). Sikder et al (2014) experimented with assessing the groundwater quality of the western area of Khulna in the pre-monsoon season and obtained EC value of drinking water ranged from 789 to 1230 μS/cm, whereas Adhikary et al (2012) observed an average EC value of 1777 μS/cm by researching six wards of Khulna City Corporation.…”

“…The excess extraction of GW from the aquifer for drinking and irrigation purposes decreases the freshwater supply by lowering the GW table and eventually sea water enters into the GW zone to fill up the gap. Excess salt concentration also changes other water quality parameters and alters the natural composition of water (Abdalla et al 2010;Adhikary et al 2012;Van Camp et al 2014). Side by side, continuous use of polluted water results in a detrimental effect on human health and socio-economic development (Milovanovic 2007).…”

Valuation of water quality index (WQI) is one of the simplest, easily understandable, and efficacious techniques to evaluate the quality and suitability of water for drinking as well as other purposes. This research was aimed to investigate the drinking water quality of tube wells from different areas in Khulna City, Bangladesh, by developing the WQI. Water samples from 59 tube wells were collected from different locations during the pre-monsoon time. pH, electric conductivity (EC), dissolve oxygen (DO), total dissolved solid (TDS), chloride (Cl−), nitrate (NO3−), and total hardness of the collected water samples were analyzed for the calculation of WQI. The mean value for pH, EC, DO, TDS, Cl−1, NO3−, and total hardness was 7.30, 1650 μS/cm, 1.60 mg/l, 1188.7 mg/l, 414.6 mg/l, 0.029 mg/l, and 52.03 mg/l, respectively. The calculated WQI values for individual places were distributed spatially through mapping by using ArcGIS software. Based on the WQI values, the drinking water was categorized into excellent, good, poor, very poor, and unfit for drinking purposes. The calculated WQI values ranged from 40.11 to 454.37 with an average value of 108.94. Among all the groundwater samples, 11.86% were excellent, 54.24% were good, 23.73% were poor, 1.69% were very poor, and 8.47% were unfit for drinking purpose based on WQI. The results showed that the groundwater quality of most of the studied areas of Khulna city could be considered safe and suitable for drinking barring the elevated EC and chloride content in some areas. Since Khulna city is situated in the southwestern part of Bangladesh and gradually approaches toward the base level of the Bay of Bengal which might be the source of salt concentration in the groundwater of Khulna city, Bangladesh.

“…The observed TH levels were within the permissible limit for drinking as per WHO guidelines (WHO 2008). Generally, water is considered soft, moderately hard, hard and very hard with TH values < 75, 75-150, 150-300 and >300 mg/L, respectively (Adhikary et al 2012). Based on the mean TH levels, the water samples were categorized as moderately hard waters, indicating their suitability for agricultural use (Simsek & Gunduz 2007).…”

The paper describes the studies of physicochemical parameters of the water samples from Lower Dudhana Dam in parbhani district of Maharashtra State during the monsoon, winter & Sumer season. Some important parameters like temperature, pH, total hardness, Calcium hardness, magnesium hardness, Dissolved oxygen, total alkalinity, chloride, total dissolved solids, fluorides & electrical conductivity were analyzed for water samples. The analytical results reveal that some treatment is required to use the water for domestic purpose.
