“…Globally most geothermal systems give unequivocal evidence of having been derived from meteoric water. This simply implies that solutes in both thermal and non-thermal waters are acquired later during the course of the geochemical evolution of the hydrological system (Aher 2019). In determining the source of dissolved chemical species in solutions with varying TDS concentrations (from less than 100 to >10,000 mg/L), we naturally have to invoke processes like dissolution of water-soluble minerals and ion exchange as a result of water -rock interaction.…”

Geothermal energy, with associated low-carbon emissions compared to conventional fossil fuels, is presently one of the potential renewable energy sources. The decryption of the chemistry of thermal manifestations of geothermal systems, in terms of relative abundances of various chemical facies, is mandatory before launching systematic geothermal exploration in a given area as it provides valuable information on the basic characteristics of the geothermal reservoir. For the present study, three clusters of hot springs have been selected -1) Shyok-Nubra valleys geothermal prospect in NW Himalaya, 2) Subansiri valley geothermal areas in NE Himalaya and 3) the hot spring system occurring along Munger-Saharsa Ridge Fault Zone (MSRF) in the Eastern part of India. The study of these geothermal systems with low to moderately high temperatures of 35−75°C, has been carried out with two main objectives. The first objective is to estimate reservoir temperature and other characteristics in the three above-mentioned hot spring groups using conventional chemical geothermometry techniques for the first-hand assessment of the quality of the geothermal resource and postulating its possible application. The second objective of the study is to understand the distribution of stable isotopes (δ2H and δ18O) in the studied geothermal systems to reveal reservoir-related hydrological aspects of the geothermal system. The three groups of hot springs show large variations in total dissolved solids (TDS) from <150 to about 1800 mg/L. Enigmatic and inexplicably low TDS values of 126 to 150 mg/Lare reported from the three Bhimband hot springs along MSRF Zone. These springs discharge Ca−Mg−HCO3 type water. The dearth of dissolved ionic species in these springs indicates lack of water-rock interaction in Bhimband area. Silica is the most abundant solute species and corresponds to a reservoir temperature of about 75°C. It may be inferred that relatively inert lithology in the reservoir and very high water-to-rock ratio might have rendered the observed chemical signatures to Bhimband hot springs. Shyok-Nubra springs at Changlung and Panamik are predominantly Na-HCO3 type with TDS values of about 1700 and 550 mg/L, respectively. These hot springs give an indication of water-rock interaction in different types of lithology at temperatures of 120 to >150°C resulting in the observed chemical differences between the two. Thermal water at Taksing in NE Himalaya is also Na−HCO3 type. Chetu hot spring with TDS of >1100 mg/Lis anomalous in two ways. First, it has a very high SO4 content of 358 mg/Land second, it has the lowest silica value. There is a possibility that the Chetu hot spring has its chemistry influenced by the dissolution of sulfates of Ca and Na. Preliminary stable isotope study indicates that the geothermal fluid is derived from meteoric sources. The lack of any indication for positive δ18O-shift suggests that reservoir temperatures of the springs are generally low.

“…Taking the world's total population as 7.5 billion, so it is a vital matter of concern to use the total accessible water wisely and effectively with minimum wastage. It is only the 8% of the planet's fresh water those are used for domestic purpose and rest 80% are being used for cultivation and industrial purposes (Aher et al, 2019). Due to the scarcity of fresh water, over a billion people deficits to clean drinking water.…”

The current research was conducted to assess the groundwater quality in the Patancheruvu area of Sangareddy District, South India. To analysis physicochemical parameters, 16 groundwater samples were collected for the month of May and November, 2020. The chemical analysis results show that the ground water nature in the study area is alkaline to basic and is classified very hard water. High TDS concentrations in the study area is due to various industries and anthropogenic activities. In both seasons, the order of major cations and major anions is in the following order: Na > Mg > Ca > K and Cl > SO 4 > HCO 3 > NO 3 > F respectively. The majority of the EC, TDS, Na, TH, Mg, Ca, Cl, HCO 3 , and SO 4 samples exceeded the desirable limit, and some samples also exceeding the permissible limit. In both seasons, the dominant hydro chemical facies identified by the Chadha diagram were Na-K-HCO 3 and Ca-Mg-HCO 3 . Water quality analysis said that most of the data in both seasons fell into poor to very poor category. The research tells that around Patancheruvu groundwater quality is poor, thisis attributed due to both anthropogenic factors and geogenic processes.

This study evaluated the possibility of conjunctive use (CU) of shallow groundwater (SGW) and surface water for irrigation at the Wonji Shoa Sugar Estate (WSSE) (Ethiopia). Irrigation suitability was investigated by taking 46 SGW samples from piezometers and hand‐dug wells. Many physicochemical parameters (Mg2+, Na+, Ca2+, K+, CO3−, SO42−, HCO3−, Cl−, TH, EC, TDS and pH) and other indices (MAR (magnesium adsorption ratio), SSP (soluble sodium percentage), SAR (sodium absorption ratio), RSC (residual sodium carbonate), KR (Kelly's ratio) and permeability index (PI)) were analysed following standard procedures. The salinity and infiltration problems of SGW were found to be none to moderate with no chloride and boron ion toxicity. The sodium ion toxicity problems are slight to moderate. The SGW is generally categorized under C3S1 (high salinity and low sodium hazard). However, a high value of SSP and RSC indicates a high possibility of occurrence of infiltration problems when using SGW. Hence, CU of SGW and surface water must be practised to minimize the potential problems of infiltration and salinization and their associated difficulties in soil and sugar cane productivity. Therefore, during CU planning, optimum irrigation scheduling that considers the in situ use of groundwater table must be practised. © 2019 John Wiley & Sons, Ltd. © 2019 John Wiley & Sons, Ltd.
