Workshop Description

Leading practitioners will illustrate challenges and best practices in metal leaching and ARD. Topics include case studies and new ideas about closure, characterization, mitigation, and genomics.   Case studies will be drawn from mine sites around the world.

This year’s workshop will again be completely virtual.  While we will greatly miss the opportunity to meet in person, this format offers us the ability to broaden our reach through an increased number of registration spots and to facilitate speakers and attendees from around the world.
