Ground water quality interpretation in coastal Srikakulam, Andhra Pradesh by using principal component analysis

Abstract

An attempt was made to study the ground water quality. Water samples were collected from 51locations in Uddanam region and analyzed for 10 water quality variables. The principal components analysis (PCA) applied to define the parameters responsible for the main variability in water quality variance for Uddanam ground water. The PCA produce three significant main components and explain more than 77% of the variance. Namely, seasonal effects, agricultural effects and geological effect that represent 54.8%, 12.53%, and 11.01% respectively, of the total variance of water quality in Uddanam area. The results of PCA reflected a good look on the water quality monitoring and interpretation of the groundwater.
