“…Following TDS classification as proposed by [8], shallow groundwater in the area is saline (Table 2), whereas deep groundwater is classified as fresh (TDS < 1000 mg/L in 15 samples) to brackish (TDS > 1000 mg/L in 7 samples). In coastal aquifers, TDS levels in groundwater are raised by higher concentrations of Cl − , Na + , and Ca 2+ when saltwater intrudes and mixes with groundwater [32]. This is true for the shallow groundwater of the study and few samples from the deep aquifer especially those near the ocean.…”

Knowing the quality of water is imperative if the water is meant for drinking or agricultural purposes. The spatial and temporal groundwater quality in the Heuningnes Catchment was investigated, and its appropriateness for irrigation and drinking purposes was considered. Thirty-one samples were collected and analysed for physical (pH, EC, TDS) and chemical (Na + , K + , Ca 2+ , Mg 2+ , HCO 3 − , Cl − , SO 4 2−) parameters. Maps demonstrating the spatial and temporal distribution of groundwater quality were constructed using Geographical Information System software. These maps indicate variations in the concentration of various water quality parameters in the region. Groundwater in the region is mostly alkaline and is categorised as either fresh, brackish or saline based on TDS classification. Using Piper diagrams, it is shown that Na +-Cl − water type is the main water type in the area. The quality is mostly influenced by chemical weathering of rockforming minerals. Over 50% of groundwater in the region is not fit for drinking purposes as established from WHO (2011) and SANS241 criteria. Following SAR criteria, looking at Na%, PI, MH, KR and salinity hazard for irrigation assessment, it was discovered that shallow groundwater in the region was not fit for irrigation purposes. However, groundwater from deeper boreholes proved otherwise. The study has shown that not all-available groundwater is suitable for either drinking or irrigation. Therefore, it recommends to plant crop varieties that are highly salinity tolerant, as treating the water prior to irrigation would not be economically viable, and it also recommends further exploration to make the available 50% of groundwater drinkable and to make the shallow groundwater fit for irrigation.

“…The required calculations and graphical presentations involved in analysis of the experimental data, along with correlation analysis were carried out using MS-EXCEL-2019. The hierarchical cluster analysis (CA) was carried out using SPSS software to group the macrophyte species based on similar bioaccumulation capacities from the external environment, and their results were presented in the form of a dendrogram (Tiri et al 2017;Prusty et al 2018).…”

A comprehensive assessment was conducted to evaluate the accumulation of selected heavy metals and nutrients in 10 dominant macrophyte species growing in the Loktak Lake, a Ramsar site, and to assess the potential health risks associated with the consumption of the edible plants. The concentrations of nutrients such as total phosphorus (TP), total nitrogen (TN), potassium (K), calcium (Ca), magnesium (Mg), and heavy metals such as copper (Cu), manganese (Mn), zinc (Zn), and iron (Fe) were measured, and found to be present in the order of plant > sediment > water. The bioaccumulation factors (BAFs) revealed high e ciency of most plants to accumulate heavy metals and nutrients in their tissues from the lake water and sediments, indicating their potential to be used as phytoremediators. Translocation factors (TFs) were also estimated to determine the e ciency of the plants to translocate elements from root to shoot. Colocasia esculenta and Polygonum perfoliatum were found to exhibit the highest BAF and TF values for most of the parameters. Target hazard quotients (THQs) revealed potential health risk associated with one or more heavy metals in the plants, except for Zn whose THQ values were below the level of concern in all the edible plant species. The hazard index (HI) signifying potential non-carcinogenic health risk from the combined effects of all the heavy metals was found to be highest for Polygonum perfoliatum, indicating a potentially higher risk to health if this edible macrophyte is regularly consumed in higher quantities and may pose long-term health effects to the exposed population.

“…The hydrogeochemical interactions are influenced by various geochemical reactions and dissolution processes such as oxidation-reduction reactions, precipitation, sorption, hydrogeological conditions, and climatic factors (McSween et al 2003;Drever 1997). Thus, assessing basic ions in groundwater can extensively explain the hydrogeochemical interaction in the aquifer formations, dissolution of contaminants, and water types of a region (Prusty et al 2018;Mukherjee et al 2012). Similarly, these basic ions can also be used to assess the irrigation water quality that can cause severe impacts on the fertility and productivity of the soil (O'Geen 2015;Fetter 2007).…”

Geochemical and multivariate assessment of groundwater resources of churachandpur sub-division of Manipur, India

et al. 2022

Hydrogeochemical and multivariate assessment of groundwater samples of the Churachandpur sub-division of the state of Manipur was carried out to study its suitability for potable and irrigational uses. The study extensively discusses the underlying hydro-geochemistry using multivariate geostatistical tools for physicochemical parameters of 35 spatially distributed groundwater samples during pre- and post-monsoon seasons. In situ parameters (pH, TDS, DO, EC, salinity, ORP) were assessed in field conditions, and it was found that few samples exceed concentration than the prescribed standards. Both positive and negative ORP values and low DO levels of the samples indicate oxidizing and reducing aquifers due to recent unstable geologic formations. Although the concentration of Cl−, SO42−, and NO3− is well within desirable levels, the concentration of F− and As3+ of a few samples exceeds the prescribed standard. The water quality index of the groundwater samples signifies that more than 50% of samples are unsuitable for potable uses for both seasons. The geochemical analysis indicates that most of the water is Ca–Mg–Cl–HCO3 type followed by Mg–Ca–Cl–HCO3 types in both the seasons and dominated by the rock-weathering geochemical process. Multivariate analysis and geostatistical mapping highlight the spatial variability of water quality parameters and possibilities of the occurrence of geogenic contaminants in the aquifers of the study area.
