Assessing the Long-Term Performance and Impacts of ISCO and ISBR Remediation Technologies

Abstract

There is a critical need to conduct accurate, quantitative performance assessments over longer time scales. This is especially important for the many complex sites that contain DNAPL source zones and large groundwater contaminant plumes comprising persistent contamination, which are recognized to present the most difficult challenges to site closure. The implementation of longer-term performance assessments is expected to reduce the risk and costs associated with remediation and management of these complex sites. The overall goal of this project was to demonstrate the effectiveness of longer-term performance assessments for evaluating the benefits of remedial actions. The specific objectives of the project were as follows: 1. Assess the long-term performance of fracturing enhanced ISBR remediation for a specific application site. 2.Compare the observed performance of the FE-ISBR project to the prior ISCO project conducted at the same site. 3.Compare the observed performance of the FE-ISBR project to other projects that have employed fracturing to enhance amendment delivery for ISBR or ISCR.
