2011
Paul, Supantha | Mishra, Umesha
This study was aimed to assess the quality of underground water using the concept of information entropy and Pearson correlation matrix. The area chosen for this study was a remote city named Agartala situated in the industrially underdeveloped state of Tripura in the northeastern zone of India. The various physicochemical characteristics of groundwater tested include pH, electrical conductivity, TDS, turbidity, Fe, Cu, Zn, K, Ca, Mg and total hardness (TH). Total 22 samples were collected from the study area and each sample was analysed for 11 parameters. Then a quality rating scale was used to find the water quality index of respective samples from each site. Ground water is here severely polluted due to unusual high concentration of iron with value as high as 28.5mg/L found in some sites. Pearson correlation matrix was formed for all the sample size. Results revealed that ground water is unfit for either drinking or agricultural purpose.
