Gary Steinbauer speaks with Peter L. Gray, co-chair of Dentons' U.S. Environment and Natural Resources Practice and author of the Superfund Manual: A Practitioner's Guide to CERCLA Litigation, about the changing legal issues dominating the CERCLA landscape.

Contaminated sites addressed under CERCLA are now more complex and significantly more expensive. Sponsored by the ABA Section of Environment, Energy, and Resources.
