REMEDIATION TECHNOLOGIES DEVELOPMENT FORUM
NON-AQUEOUS PHASE LIQUID (NAPL) CLEANUP ALLIANCE

Progress Report
First Quarter 2002

Introduction

The Non-Aqueous Phase Liquid (NAPL) Cleanup Alliance was established early in 2001 as one of the six active Action Teams under the Remediation Technologies Development Forum (RTDF). The RTDF fosters collaboration between the public and private sectors in developing innovative solutions to mutual hazardous waste problems. The Alliance is made up of representatives from the petroleum industry, federal and state government, and academia who share an interest in evaluating a range of technologies for remediation and management of large-scale, non-aqueous phase liquid (NAPL) contamination.

This report documents progress of the NAPL Cleanup Alliance during the first quarter of 2002.

Accomplishments

  1. The Project Technical Working Group continued work on a pilot project to address NAPL contamination at a former refinery site in Casper, WY. Work on the project focuses on analyzing the mobility and behavior of hydrocarbons at the site and evaluating various cost-effective cleanup technologies to identify feasible remedies that reduce contaminant concentrations below practical endpoints, so that the site would be considered acceptable for future re-use. During the quarter, the Working Group began preparing a report on results of the first two stages of an investigation of the site to provide data for an evaluation of NAPL distribution, mobility and natural attenuation mechanisms. The report will be available in Spring 2002 and will be posted on the RTDF/NAPL Cleanup Alliance World Wide Web site (www.rtdf.org/public/napl/). In addition, the Working Group, based on its analysis of results achieved to date, continued planning future phases of the site investigation.
  2. The Decision Framework Working Group presented its concept for a NAPL Management Decision Framework to the Interstate Technology and Regulatory Council (ITRC) at its March 2002 meeting. ITRC members and other state and federal regulators are being invited to review and comment on the draft outline for the framework during the Alliance's April 2002 meeting.
  3. The Technical Information Working Group continued its cooperation with an ongoing project for the Ground-Water Remediation Technologies Analysis Center (GWRTAC), sponsored by the U.S. Department of Energy, to compile a searchable database of existing information on NAPL research and cleanup projects in the United States and Europe. When the database is completed, the information will be made available via the Internet. The Alliance (www.rtdf.org/public/napl/) and GWRTAC (www.gwrtac.org) will provide access to the database via their Internet sites.
  4. The next Alliance meeting is April 16-17, 2002.
