Increasing the cost effectiveness of site remediation is a national priority. The selection and use of more cost-effective remedies requires better access to data on the performance and cost of technologies used in the field. To make data more widely available, member agencies of the Federal Remediation Technologies Roundtable (Roundtable) are working jointly to publish case studies of full-scale remediation and demonstration-scale projects. Previously, the Roundtable published 13 volumes and a CD-ROM of case study reports. At this time, the Roundtable is publishing a CD-ROM containing 39 new case study reports (313 reports total), primarily focused on contaminated soil and groundwater cleanup. The CDROM also includes 274 previously published reports.
