The State of the Practice: Characterizing and Remediating Contaminated Groundwater at Fractured Rock Sites

Characterizing and remediating contaminated groundwater in fractured rock are often the most difficult challenges facing environmental professionals. The U.S. Environmental Protection Agency (EPA), other U.S. federal agencies, and the Ontario Ministry of Environment recently supported a workshop, held an international conference, and developed a Web site to promote the understanding of the state of the practice. Field practitioners and researchers were surveyed and questioned concerning their experiences. This article summarizes the results of these efforts and provides an overview of the use of characterization methods and remediation technologies at fractured rock sites. © 2002 Wiley Periodicals, Inc.
