Environmental Geochemistry International (EGi)
Environmental Geochemistry International (EGi) is a leading and innovative consulting company with over 30 years experience in providing specialist advice on acid rock drainage (ARD or acid and metalliferous drainage - AMD) prediction and control, mine waste geochemistry and mine water hydrogeochemistry. We have pioneered the development of many of the geochemical assessment techniques routinely used today, significantly improving the understanding of ARD and the ability to predict the geochemical behaviour of mine materials. EGi offers an integrated service in ARD and mine geochemistry at pre-feasibility, feasibility, operational, decommissioning and post-closure phases of projects.
EGi was established in 1983 and has worked at more than 370 mining projects world wide, across a range of commodities and environmental settings. Our clients include multi-commodity multinational mining companies, one-mine operators, regulatory agencies, and other consultants.
EGi is committed to improving the knowledge of acid drainage issues and furthering the development of management strategies for mitigating impacts on the environment. The company’s extensive practical experience with the challenges associated with operational mines, closure of active and dismissed sites, and geochemical prediction, as well as ongoing involvement in ARD research ensures it remains at the forefront of geochemical mine waste assessment and management.
