Advances in Acid Rock Drainage: New approaches to Prevention & Remediation – Takeaways from our Webinar with John Webb.

In our recent webinar, we dissected the major problem of acid rock drainage, learning how it can destroy vegetation and ecosystems, corrode infrastructure and equipment, and pollute drinking and agricultural water – causing huge management and remediation costs both in Australia and internationally.

John Webb is an Emeritus Professor of Environmental Geoscience at La Trobe University. He specialises in groundwater geochemistry, including at contaminated sites, and is involved in research projects on improving treatment procedures for acid rock drainage. He has also worked in the fields of geomorphology, particularly landscape evolution, and geoarchaeology, including artefact and ochre sourcing. John has supervised over 100 honours students and 30 PhD students and published over 150 papers.

During the webinar, John spoke in depth on preventing acid rock drainage through mixing of acid-producing material with a neutraliser like limestone, and through the exclusion of oxygen through geofabric covers or flooding to ensure that pyrite doesn’t oxidate. We also explored several acid rock drainage treatment studies, delving into both active and passive treatment systems.

A very big thank you to John Webb for taking the time to join us and present an incredibly informative Webinar to nearly 200 live viewers.
