In Situ Chemical Oxidation for Remediation of Contaminated Groundwater: Summary Proceedings of an ISCO Technology Practices Workshop. Colorado School of Mines, Golden, CO on March 7-8, 2007

摘要

The Colorado School of Mines (CSM), in collaboration with East Tennessee State University (ETSU), CH2M HILL, and the U.S. Navy, convened a 2- day ISCO Technology Practices Workshop at the CSM in Golden, Colorado on March 7-8, 2007. The purpose of the Workshop was to provide a forum to share insights and perspectives gained regarding the application of ISCO for remediation of contaminated sites. There were 43 invited participants at the Workshop including SERDP/ESTCP program staff, ISCO project team leaders, and key ISCO stakeholders (chemical companies, technology vendors, environmental consultants, researchers, and remedial project managers). The Workshop program was designed to encourage participation and consisted of a series of technical presentations, four panel discussions, a contaminated site scenario exercise, three breakout group meetings, along with several periods of plenary discussions. This proceedings document summarizes the activities and outcomes of the workshop. Highlights of some views and consensus that emerged from the Workshop are given below. There was general consensus that while ISCO as a remediation technology may be considered for a wide range of situations, site-specific conditions interact with ISCO technology attributes and determine the performance that would be considered reliably achievable. As an illustration of this view, a strong majority of the Workshop participants responding to the scenario assignment indicated that they would personally consider ISCO for all six of the contaminated site scenarios. However, the degree of anticipated ISCO performance, time-frame necessary and estimated costs varied for all of these scenarios. Furthermore, different types of treatment objectives may be more or less achievable depending on site-specific conditions.
