ABSTRACT

 

Correlation co-efficient of various physico-chemical parameters of ground water for Narayanpur is employed to interpret the relationship with specific processes that control the quality of ground water samples collected from the Narayanpur area, Nalgonda district, Andhra Pradesh (India). The samples were analysed for major ions and evaluation for quality was carried out by using hydrochemical approach with graphical and multivariate statistical methods with the objective of identifying the hydrochemical environment of the area. Results indicate that the concentration of fluoride is very alarming with respect to use of water for drinking purpose. Various graphical plots and statistical techniques/tools have been applied to chemical data based on the ionic concentration water type is identified. The statistical analyses among different water parameters were determined and their correlation coefficients indicate that there is a good correlation between EC and TDS, EC and Na etc. The quality fluctuations of different ionic parameters have been studied and correlated for different indices.
