Multivariate statistical technique for the assessment of ground Water Quality in Coonoor Taluk, Nilgiri District, Tamilnadu, India

Abstract

Ground water is one of the most important resources which play a key role in sustainable development. Over the lastfew decade, the industrial development and population growth has increased the water utilization which creates stresson both water and land resources. In such scenario, assessment of water quality is essential for proper management andutilization. This paper presents the usage of statistical method like Principal Component Analysis and Pearson Correlationcoefficient analysis for analysing temporal variations of the ground water. From Coonoor Taluk of Nilgiri district, varioussamples were collected to analyse physico-chemical factors. The quality of the ground water and the compositions are tobe determined by Water Quality Index (WQI) calculation method. A comparison of each parameter with that of standardpermissible limit as recommended by WHO.
