The Handbook of Suggested Practices for the Design and Installation of Ground-Water Monitoring Wells is intended to assist personnel involved with the design, construction, and installation of ground-water monitoring wells. The document does not focus on specific regulatory requirements, but instead presents state-of-the-art technology that may be applied in diverse hydrogeologic situations. The 'Handbook' addresses field-oriented practices to solve monitoring well construction problems rather than conceptual or idealized practices. The information in the 'Handbook' is presented in both matrix and text form. The matrices use a relative numerical rating scheme to guide the user toward appropriate drilling technologies for particular monitoring situations. The text provides the narrative overview of the criteria that influence ground-water monitoring well design and construction in various hydrogeologic settings.
