“…Correlation matrices and principal component analysis (PCA) on both surface and ground water established higher EC and TDS in relation to salinity stress due to Na + , K + , Cl − , and higher total hardness (TH) in relation to Ca 2+ , Mg 2+ , PO 4 3− , and SO 4 2− [30]. Islam et al further examined 46 groundwater samples of Gopalganj district (23 post-monsoon and 23 pre-monsoon periods) ranging from the depth of 48 m to 200 m [32]. Hydrochemical analysis revealed groundwater in this area was neutral to slightly alkaline and dominating cations were Na + , Mg 2+ , and Ca 2+ , along with major anions Cl − and HCO 3 − .…”

Increasing salt intake has substantial negative impacts on human health and well-being. This article focused on the construction of Driver-Pressure-State-Impact-Response (DPSIR) framework for drinking water sodium (DWS) followed by a review on the published studies regarding salinity intrusion, DWS, and their effects on health perspectives in Bangladesh. Saline water is an important factor for hypertension or high blood pressure in the coastal areas. DWS can also lead women, especially pregnant women, to an increased risk of (pre)eclampsia, hypertension, as well as infant mortality. Several interventions, such as rainwater harvesting, pond sand filter (PSF) system, managed aquifer recharge (MAR), and pilot scale solar-powered desalination plants, such as reverse osmosis (RO), were reviewed on the context of their effectiveness in controlling drinking water sodium. Although rainwater consumption has the positive impact of low or no sodium intake, it still possesses negative impacts from not having vital minerals. A steady increment in sodium concentration through the span of the dry season was observed in MAR. It is, subsequently, important to increase awareness on DWS intake by providing and adopting correct technological interventions and training communities on the maintenance of the adaptive measures.

“…The water quality index (WQI), which has been applied in many countries, as well as in the Mekong River basin, is one of the more prominent methods for representing the level of water quality, and combines several physico-chemical and biological parameters into a single number [35,36,[74][75][76][77][78][79][80]. The standard of water quality for the whole lower Mekong River basin was evaluated in An Giang.…”

The Vietnamese Mekong Delta (VMD) is one of the largest rice-growing areas in Vietnam, and exports a huge amount of rice products to destinations around the world. Multi-dike protection systems have been built to prevent flooding, and have supported agricultural intensification since the early 1990s. Semi-dike and full-dike systems have been used to grow double and triple rice, respectively. Only a small number of studies have been conducted to evaluate the water quality in the VMD. This study aimed to analyze the spatiotemporal variation of water quality inside the dike-protected area. Surface water samples were collected in the dry and wet seasons at 35 locations. We used multivariate statistical analyses to examine various water quality parameters. The mean concentrations of COD, NH4+, NO3−, PO43−, EC, and turbidity were significantly higher in water samples inside the full-dike system than in water samples from outside the full-dike systems and inside the semi-dike systems in both seasons. High concentrations of PO43− were detected in most of the primary canals along which residential, tourist areas and local markets were settled. However, NO3− was mainly found to be higher in secondary canals, where chemical fertilizers were used for rice intensification inside the dike system. Water control infrastructures are useful for preventing flood hazards. However, this has an adverse effect on maintaining water quality in the study area.

“…28) in the dry season, respectively (Table ). This change in pH values is attributable to the low alkalinity of rainwaters, agricultural activities and leakage of dissolved components into the groundwater (Islam et al, ). The pH interval recommended for irrigation waters is 6.5–8.0 (World Health Organization (WHO), ).…”

“…Parameters such as SAR, KR, Na%, PI, RSC and MH in addition to EC are taken into account to determine the suitability of groundwater within the research area for agricultural irrigation. SAR, KR, Na%, PI, RSC and MH the values were calculated using the equations in Table are given in Table , and a rating system for groundwater quality in terms of EC, SAR, KR, Na%, PI, RSC and MH was established on the basis of standard value intervals (Shabbir and Ahmad, ; Seth et al ., ; Wilcox, ; Islam et al, ) for irrigation water quality given in Table . Additionally, an evaluation based on the USA salinity diagram was made to fully determine the suitability for agricultural irrigation.…”

In this study, the physical and chemical characteristics of wet and dry season groundwater quality parameters of 35 wells within the provincial boundaries of Sivas were used for calculations such as sodium adsorption ratio (SAR), Kelly's ratio (KR), sodium percentage (Na%), permeability index (PI), residual sodium carbonate (RSC) and magnesium hazard (MH), which are used in irrigation water quality ratings. Also, the irrigation water quality index (IWQI) was calculated for all groundwater sources within the study area. Groundwater quality parameters and the spatial distribution of the parameters calculated throughout the study were mapped using GIS, and irrigation water quality evaluation was performed in accordance with USA Salinity Laboratory diagram and irrigation water quality standards. The correlations between the irrigation water quality parameters were determined using Pearson correlation analysis. IWQI values showed that the majority of groundwater samples (45.7%) are in the ‘weak' (MR: medium rating) category for the dry season, whereas 42.9% of groundwater samples fall within the ‘very weak' (HR: high restriction) category for the wet season. © 2019 John Wiley & Sons, Ltd.
