MITRE assembled design, cost, and performance information on five frequently applied remedial technologies from more than 100 vendors directly involved in equipment design and construction and whose costs are independent of contractor markup. This document summarizes the practical experience gained by these vendors through thousands of site remediation projects. The Air Force Center for Environmental Excellence/Environmental Services Office requested this work to obtain an independent, conflict-free source of information for evaluating their contractor's selection of remedial technologies, equipment design, cost estimates, and proposals.
Introduction
This article is one of a series of articles on the technical aspects of site remediation. The Air Force Center for Environmental Excellence (AFCEE) at Brooks Air Force Base, Texas, assembled this information in support of Air Force remediation project managers implementing the Installation Restoration Program (IRP). The articles summarize technical information and opinions obtained from the vendors of remediation equipment regarding the design, performance, and cost of their products. The information was assembled and analyzed approximately 2 years ago, and it may prove helpful to participants of site remediation projects.
Stabilization and solidification reduce the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, stabilization and solidification seek to trap or immobilize contaminants within their "host" medium, that is, the soil, sand, building materials, and incinerator residues that contain them, instead of removing them through chemical or physical treatment. The measure of immobility used for site remediation is the EPA toxicity characteristic leaching procedure
