Abstract
The present work aims at the evaluation of groundwater quality at certain industrial areas in and around Bharat Heavy Electrical Limited (BHPV), Natural Thermal Power Corporation Ltd. (NTPC) and Hindustan Petroleum Corporation Ltd. (HPCL) in Visakhapatnam city, Andhra Pradesh. Ground water samples are collected from all the three industrial zones and subjected to physico-chemical analysis for various parameters such as pH, Turbidity, Conductivity, Total Acidity, Total Hardness, Chlorides using standards of APHA. Water Quality Index is calculated by using the popular NSFWQI method and the quality of the water is rated as unfit for drinking. The data is subjected to statistical analysis using SPSS 20.0 software. The statistical methods used for the data analysis are Cluster Analysis and Factor Analysis. Based on the WQI and Statistical analysis, the contamination is observed due to the presence of excess amounts of hardness and chlorides.
