Water quality mainly depends on its physiochemical as well as microbial characteristics. Present study was directed to evaluate the quality of groundwater as well as its drinking suitability, domestic, and agricultural uses by applying physico-chemical experiments. To achieve this objective, Hura Block of Purulia district under West Bengal was selected as the field of experiment and samples were collected from different positions using global positioning system (GPS) coordinates as reference points. Hura, a community development block within the Purulia Sadar subdivision of Purulia district. Detailed analysis of different physico-chemical parameters like colour, odour, temperature (T), total dissolved solid (TDS) hardness (HA), electrical conductivity (EC), calcium (Ca2+) ion, magnesium (Mg2+) ion, pH level, total alkalinity (TAK), chloride (Cl-) ion, fluoride (F-) ion, bicarbonate content (HCO3-), free carbon-dioxide (CO2), and dissolved oxygen (DO) was carried out. A comparative analysis of the experimented results was done with respect to the standard water quality parameters set by WHO (World Health Organization) and BIS (Bureau of Indian Standards).To verify the suitability of water for different purposes, the WAWQI (Weighted Arithmetic water quality index) method was applied by using the experimented values of different parameters. Additionally, to determine the interrelationship between the different parameters, the correlation coefficients were measured by using Pearson’s correlation matrix method.
