Delivery and Mixing in the Subsurface: Processes and Design Principles for In Situ Remediation, the fourth installment in a Remediation Technology Monograph Series*, describes the principles of chemical delivery and mixing systems and their design and implementation for effective in situ remediation. Released earlier this month, this monograph was written by several leading experts from academia and industry and edited by Dr. Peter K. Kitanidis and Dr. Perry L. McCarty of Stanford University. It will serve as a reference for decision makers, practicing engineers, and hydrogeologists who select, design and operate remedial systems, as well as the researchers seeking to improve the current state of the science and technology.

The initial chapters of the monograph provide tutorials on chemical and biological processes as well as transport and mixing relevant to groundwater remediation. The authors present conceptualization and modeling approaches, including the travel-time approach. Subsequent chapters cover design issues with recirculation systems, reactive barrier walls, air sparging, intrinsic remediation in natural-gradient systems, and source remediation. Case studies are provided.

A series of related reference books is planned on topics that include bioaugmentation for groundwater remediation, chlorinated solvent source zone remediation, remediation of contaminated sediments, and remediation of munition constituents in soil and groundwater.  In facilitating this monograph series, SERDP and ESTCP seek to provide the broader remediation community with the most current knowledge and tools available in order to encourage full and effective use of these technologies.
