Injected water and treatment agents are isolated within the underlying aquifer and recovered together with flushed contaminants.
4.8 Soil Flushing (In Situ Remediation Technology)
A Citizen's Guide to In Situ Flushing The Citizen's Guide Series are 2-page fact sheets that provide a general description on approaches to clean up contaminated waste sites. The fact sheets cover five questions about each clean up approach: What is it?, How does it work?, Is it safe?, How long will it take?, and Why use it?.
Guía para el Ciudadano sobre Enjuague In Situ La Serie de Guías del Ciudadano son boletines de dos páginas con datos que proveen una descripción general en cómo sanear sitios contaminados. Estos boletines con datos que cubren cinco preguntas acerca de cada procedimiento de saneamiento: ¿Qúe es?, ¿Cómo trabaja?, ¿Es seguro?, ¿Cúanto tiempo requerirá?, y ¿Por qué debe de usarse?
Surfactant Enhanced Aquifer Remediation
Technology Overview Report: In Situ Flushing This report prepared by the Ground Water Remediation Technologies Analysis Center (GWRTAC) provides an introduction to the general principles of in situ flushing technology, its criteria for application, performance, advantages and limitations to use, and references.
Treatment Technologies for Site Cleanup: Annual Status Report (ASR), Twelfth Edition The Twelfth Edition of this report, published by the EPA Office of Superfund Remediation and Technology Innovation (OSRTI) in September 2007, documents treatment technology applications at more than 1,900 soil and groundwater cleanup projects at National Priorities List (NPL) sites. The status of more than 1,200 projects included in the ASR Eleventh Edition is updated, and information about 192 new projects derived from Records of Decision (ROD) signed from 2002 through 2005 is added. The report also includes a special section about on-site containment remedies. The ASR is based on the analysis of nearly 3,000 RODs signed since 1982 at 1,536 NPL sites. The online version includes new downloadable spreadsheets with the data for several of the key tables and figures in the report. Specific information about each technology application included in the ASR Twelfth Edition is available in the ASR Remediation Database.
