“…Nitrogen contaminants, such as nitrate, nitrite, and ammonia nitrogen, are prevalent inorganic contaminants. Nitrate is predominantly from anthropogenic sources, including agriculture (i.e., fertilizers, manure) and domestic wastewater (Hansen et al 2017 ; He and Wu 2019 ; He et al 2019 ; Karunanidhi et al 2019 ; Li et al 2019a ; Serio et al 2018 ; Zhang et al 2018 ). Groundwater nitrate contamination has been widely reported from regions all over the world.…”

“…Disposal of untreated domestic and industrial effluents and indiscriminate use of agrochemicals have rendered the groundwater unfit for irrigation purposes. Overall, groundwater of the region is Composite irrigation water quality zonation map of the study area unsuitable for long-term irrigation, considering the high magnesium and sodium hazard and salinity in the water [26]. High Na + content in the irrigational water can replace Ca 2+ and Mg 2+ ions in the soil, which further makes the soil compact by reducing its permeability [10].…”

The groundwater is the main source for irrigation and other purposes in the alluvial plains of Punjab. The poor irrigational water quality affects the soil quality which interrupts the growth of plants impacting the agricultural production and can cause risk to human health, and thus, it is important to evaluate the water quality for irrigation uses in the agrarian regions. An integrated GIS-based modelling approach along with conventional water quality indices such as sodium adsorption ratio, per cent sodium, residual sodium carbonate, residual sodium bicarbonate, magnesium hazard, permeability index, potential salinity, Kelly's ratio, electrical conductivity, total hardness, pH and total dissolved solids was used to delineate the irrigation water quality suitability zones in parts of agricultural prolific Satluj River Basin. Analytical results revealed that groundwater of the study area is very hard and slightly alkaline in nature and the relative abundance order of major ions is Mg 2+ > Na + + K + > Ca 2+ and HCO 3 − + CO 3 2− > Cl − > SO 4 2− , respectively, for cations and anions. The weighted overlay technique was applied to generate the irrigation water quality zonation map, and results revealed that nearly 3.2% (117 sq. km) of the total area was not suitable for the irrigation water quality, whereas 85.2% (3076 sq. km) and 11.6% (421 sq. km) area fall under moderately suitable and suitable classes, respectively. The elevated level of some ions found in the shallower zone as compared to the deeper zones indicates that in addition to the geogenic factors (weathering and dissolution of aquifer materials) anthropogenic inputs such as ill agricultural practices, leaching from septic tanks and municipal waste are adversely affecting the groundwater system in the region. The results of US Salinity Laboratory's diagram showed that 42% groundwater samples fall in C3S1 (high salinity with low sodium hazard) category indicating the unsuitability for irrigation purpose due to high salinity hazard and cannot be used in soils with restricted drainage. The results of Piper and Durov diagrams revealed that Ca 2+-Mg 2+-HCO 3 − is the dominant hydrochemical facies with Mg 2+-HCO 3 − water type in the groundwater of the study area and hydrochemistry is controlled by both natural and anthropogenic factors. The bottom-up approach and involvement of locals can boost the management of water resources in the study area.

“…Considering the importance of groundwater and its quality degradation due to urbanization and increasing pollution, many researchers have discussed the groundwater chemistry and its human health risk assessment across the globe [6][7][8][9]. Not only the heavy metals and bacterial contamination, excess amount of basic water quality parameters such as pH, total dissolved solids, and nitrate have also been reported in groundwater owing to unsustainable use and indiscriminate subsurface discharge of various pollutants [4,7].…”

Deterioration of surface water quality in various parts of India due to increasing urbanization has led to the extensive usage of groundwater for various domestic and irrigation needs, thereby raising concerns over its quality. However, there are very few studies focussing over the issue of groundwater quality in North-Eastern region of India. In order to make an assessment of the quality of groundwater for drinking and irrigation purposes, this study was carried out in Shillong—the Capital City of Meghalaya State in North-East India during pre-monsoon and post-monsoon seasons of 2018. Standard sampling and analytical procedures were followed for groundwater quality assessment. Minimal variation was observed in the water quality of pre- and post-monsoon seasons. However, the study found that groundwater samples are having acidic pH and presence of nitrate is also reported. Some of the samples also showed the presence of mercury, nickel, and cadmium. The presence of these contaminants could be attributed to the industrial activities in the state. Overall, the groundwater quality was found suitable for drinking and irrigation purposes after conventional treatment. Hydrochemical studies further inferred that groundwater properties in the region are influenced by the rock weathering along with the atmospheric precipitation.
