WATER QUALITY INDEX FOR GROUND WATER OF RURAL AREAS AROUND ANGUL-TALCHER INDUSTRIAL ZONE, ORISSA

摘要

The water quality index (WQI) for the drinking waters of rural areas around Angul-Talcher Industrial zone, Orissa has been investigated from July 2001 to June 2003. The quality ratings of 20 physico-chemical and bacteriological parameters of water samples from 7 tube well and 7 dug wells in the region were estimated. The WQI values for all the analysed samples were less than 80 throughout the period of investigation except for 3 dug wells with 80 < WQI = 100 in the rainy season and also after heavy down-pour in summer. The results indicate that the analyzed water bodies are by and large moderately polluted and can be used only after proper treatment and disinfections.
