“…Salinity-tolerant occupations such as shellfish farming (shrimp and crab) then started replacing the crop-agro-based occupations pursued by HH. However, such practices enhanced salinity more to soil and contamination of shallow aquifers by salinity and agrochemicals (Datta et al, 2010; Islam et al, 2019; Paul & Vogl, 2011; Primavera, 1997). Because of constructed physical barriers for water management, the migration of aquatic faunal species was delimited, and many indigenous fish varieties initiated experiencing stress in breeding and sufferings from diseases (Cochrane et al, 2009).…”

Occupations in the Lower Bengal Delta have been disrupted for various reasons, such as natural disasters, social degradation, economic crisis, and political revenge. It results in changing their traditional occupations. This study discusses how traditional occupations can be made sustainable in the future. An empirical study has been conducted in two villages in the Shyamnagor subdistrict of Satkhira district in southwestern coastal Bangladesh. The empirical methods included 310 household surveys, focus group discussions, and key informant interviews. Results show that 15 professions have been recorded and grouped into four categories: zero-capital instant wage occupations, minimum capital-end rewarding occupations, intellectual occupations, and capital-based occupations, depending on the type of capital. These categories accommodate mainly hand-based occupations—a trend most experienced in stressed environmental conditions. The intellectual occupations desire more institutional support for their sustainability. However, the sustainability of current occupational strides can be achieved by healthy external subsidies for applying knowledge and tangible inputs with information, communication, and technology support, as suggested by households (HH) involved in capital-based occupations. These HH suggested an integrated approach for occupational stride; however, such occupations are primarily land-based. The current climate-induced hazards to land and water’s physicochemical attributes suggest an uncertain return from such capital-based, land-oriented occupations. Thus, this study suggests that hand-based occupations have a better chance for sustainability than subsidised capital-based land-oriented occupations.

“…The release of contaminants from diffuse anthropogenic sources as well as different natural conditions (surface water quality distance to shore, leaky conditions between aquifers, etc.) may also directly or indirectly affect the hydrogeochemical composition of the groundwater (Islam et al 2019). Yan et al (2023) reported the surface water is affected by the weathering and dissolution of both silicate and carbonate rocks, while GW is mainly affected by the weathering and dissolution of silicate.…”

In this research, multivariate statistical analysis was performed to assess the water quality of 4 important drinking water sources in the state of Rio Grande do Sul (RS), Brazil. For this, nineteen water quality parameters (WQP) were applied twice a year, for the period 2013-2018, to assess water quality from different sources. The evaluation was conducted on tree water surface (SWS) and one groundwater source (GWS), separately. Analysis of outliers, Shapiro-Wilk normality test, non-parametric Kruskal-Wallis test, Spearman correlation analysis, hierarchical cluster analysis and the Ward method were carried out to identify the quality of water from different sources. There were higher coefficients of variation for metals, color, turbidity, and total phosphorus. The multivariate analysis pointed out that variables with the highest correlation and grouping in the springs indicate the movement of soil particles into water bodies and their degradation, due to the lack of protection in the areas of these relevant sources of supply.

“…Therefore, it is necessary to disclose groundwater compositions for appraising the hydrogeochemical evolution, hydraulic connectivity between different aquifers, and its suitability for various activities. Many scholars and experts have applied the integrated approaches to enable practical interpretation on hydrochemical processes by using Piper diagram, ion ratios, isotope analysis, and multivariate statistical analysis (Mokadem et al 2015;Ahmed et al 2019;Islam et al 2019;Zhang et al 2019;Jayathunga et al 2020). Numerous published literature have reported abundant and significant researches on the hydraulic connectivity between groundwater and surface water (King et al 2014;Keshavarzi et al 2017;Shakhane & Fourie 2019).…”

The present study focuses on the shallow phreatic aquifer (SA) and the upper confined aquifer (CA) developed in Cenozoic loose strata, which are the major regional groundwater resources for drinking, irrigation, industry and other water-related activities. Seven samples from SA and seventeen samples from CA were analyzed to depict the hydrochemical characteristics, categorize the hydrochemical facies, evaluate the hydraulic connectivity, and appraise the drinking water and irrigation water quality. The abundance of cations is Na+ > Ca2+ > Mg2+ > K+ and the anions is HCO3− > SO42− > Cl− in both aquifers, respectively. Groundwater chemistry is controlled by water-rock interactions such as halite dissolution, ion exchange, reverse ion exchange, silicate weathering, and followed by the dissolution of Glauber's salt. The low connectivity and moderate connectivity between these two aquifers has engendered. The majority of the ion concentrations are within the limit for drinking, only one sample from the shallow aquifer are greater than the limit of 250 mg/L, a total of 29% from the shallow unconfined aquifer and 14% from the confined aquifer were not within the limit of 250 mg/L. The sodium absorption ratio (SAR), residual sodium carbonate (RSC) and soluble sodium percentage (%Na) values reveal that all the samples are appropriate for irrigation uses. The the US salinity laboratory (USSL) diagram shows that sixteen CA samples and all the SA samples fall in the C3S1 zone, implying high salinity hazard and low alkalinity hazard.
