This design guide provides guidance for the basic design, installation and operation of ground water extraction and ground water injection systems for the cleanup of contaminated ground water, exclusive of any treatment systems. General guidance on ground water extraction already exists. The intent of this design guide is to document lessons learned from experience and to provide a systematic approach to the installation, operation and trouble-shooting of systems. In addition, this design guide identifies aspects of ground water/fuel extraction and ground water injection systems that have led to poor performance and provides solutions to these problems. The design guide provides trouble-shooting charts that list problems, causes, solutions and preventative measures. The design guide then provides a series of checklists for the user to follow during the implementation of a project. The checklists identify information and data needs that, when addressed, greatly improve the likelihood for project goals to be achieved.
