Abstract

The paper presents the assessment of water quality status of three lakes located in the northern part of Belgaum city of Karnataka state, namely, Fort Lake, Kanbargi Lake and Kangrali Lake using factor analysis. Total 15 water quality parameters analyzed from December 2013 to May 2014 were used. The results indicated that in all three lakes six parameters namely, turbidity, BOD, DO, calcium hardness, magnesium hardness and potassium are above the desirable limits as per BIS: 10500-2012. In addition, in Kanabargi Lake, alkalinity and TDS and in Kangrali Lake alkalinity are beyond the desirable limits. Based on the results of factor analysis the significant factors influencing the quality of Fort Lake, Kanbargi Lake and Kangrali Lake are respectively categorized into four, five and four groups explaining 93.34, 100 and 94.41 % of total variances. This shows that the multivariate statistical analysis facilitate in interpreting the large data of complex nature.
