Advanced Hydraulic Fracturing Methods to Create In Situ Reactive Barriers
1997. L. Murdoch; B. Siegrist; T. Meiggs, Oak Ridge National Laboratory, TN. ORNL/CP--95423, NTIS: DE98001942, 11 pp.
Hydraulic fracturing methods offer a mechanism for emplacing in situ redox zones for treatment of organics and inorganics. Specialized methods allow the form of the fracture to be influenced, such as creation of asymmetric fractures beneath potential sources (i.e. tanks, pits, buildings) that should not be penetrated by boring. Examples of field applications of this technique are discussed. Available through the DOE Information Bridge.

Analysis of Selected Enhancements for Soil Vapor Extraction
EPA 542-R-97-007 , 1997
This report provides an engineering analysis of, and status report on, selected enhancements for the following soil vapor extraction (SVE) treatment technologies: air sparging, dual-phase extraction, directional drilling, pneumatic and hydraulic fracturing, and thermal enhancement. It also offers an evaluation of each technology's applicability to various site conditions, cost and performance information, a list of vendors specializing in the technologies, a discussion of relative strengths and limitations of the technologies, recommendations to keep in mind when considering the enhancements, and extensive references.
