This symposium will incorporate topics beyond those addressed by its predecessor, the In Situ and On-Site Bioremediation Symposium, and will reflect bioremediation’s maturity and new directions in environmental research and application. Although bioremediation will continue to be a core area, the expanded program will consider how biological technologies and strategies can be employed to assess risks to human and ecological health and to develop sustainable practices in remediation, production, and other human activities.
