Analysing the Environmental Impact on Ground Water by Oil Exploration?A Case Study in Sobhasan, Nandasan & Linch Fields of Mehsana Asset, ONGC, Gujarat

摘要

Groundwater is an important water resource for domestic and agriculture in both rural and urban parts of India. Once polluted, a groundwater body could remain so for decades, or even for hundreds of years, because the natural processes of through- flushing are slow. In this study, 10 heavy metals were measured in ground water and produced water samples. It will help obtain information the impact of E&P activities on ground water quality with respect to heavy metals. Results were compared with drinking water standards which clearly show that the E&P operations are not contaminating the ground water in the study area.
