Characterization and assessment of groundwater aquifers from Bakreshwar and Tantloi Geothermal Fields for its industrial applications

Abstract The fluent that is accustomed to the industries mainly water plays an important function in terms of the effectiveness of a process, material selection and life span of the output. The study was initiated to judge the quality of groundwater hotsprings located in Bakreshwar and Tantloi geothermal fields based on physicochemical parameters. The groundwater samples were gathered from seven distinct fields, equipped with geothermal wells. The collected water samples were analyzed for total hardness, the total amount of dissolved solids, pH factor, and quantitative study of carbonates, bicarbonates, sulfates, nitrates, sodium, magnesium, calcium, potassium and chloride contents. Apart from this, trace elements such as Fe, Li were also taken into consideration. Durov plot, Stiff's plot and various other diagrams were also adopted for investigating the suitability of groundwater use in industry. Moreover, the results were correlated and compared with water quality standards based on the Langelier Saturation Index (LSI), Ryznar Stability Index (RSI) and Aggressive Index (AI). The values and results thus obtained proposed highly – to – aggressively corrosive in nature and with a significant amount of scale formation. The assessment of the groundwater from Tantloi and Bakreshwar does not demonstrate a permissible industrial water category.
