 PURPOSE
 The development of cost effec-
 tive in-situ treatment technolo-
 gies is a major priority of re-
 search and technical outreach to
 the U.S. Environmental Protec-
 tion Agency's (EPA) Office of
 Research and Development
 (ORD) National Risk Manage-
 ment Research Laboratory
 (NRMRL), and the Office of Solid
 Waste and Emergency Re-
 sponse (OSWER) Technology
 Innovation Office (TIO).  EPA is
 interested  in  disseminating
 information to decision makers
 and potential users of these
 technologies  to promote less
 costly, more effective application
 to sites that have, historically,
 been difficult  to remediate.

 There is a recognized need to
 communicate current design and
 performance  data, technical feasi-
 bility,  implementation impedi-
jjieats^an d^cost. i nfo r mat j on Jo,
 regulators, decision makers, and
 other stakeholders who would ben-
 efit from this type  of technology
 transfer. Although much informa-
 tion is being provided on biotic
 groundwater remediation  ap-
 proaches, less is  known about
 abiotic processes. Abiotic pro-
 cesses will be the focus of this con-
 ference by exploring and evaluat-
 ing in-situ remedial options and
 current practices.
 WHO SHOULD ATTEND
 Remedial Project Managers; On-
 Scene Coordinators; State, Local,
 and Tribal decision makers, ven-
 dors, researchers, academia, and
 consultants involved with the man-
 agement and/or remediation of
 sites impacted by  contaminated
 groundwater.
