Abstract Advantages associated with hollow-stem auger drilling include rig mobility and versatility; the utility of the hollow stems for collection of representative samples of formation materials and for installation of monitoring wells; relatively fast advancement of the borehole in unconsolidated deposits; minimal formation damage in sands and gravels; minimal, if any, use of drilling fluids; and good control of drill cuttings. When drilling in heaving sands, if a positive pressure head of water cannot be maintained inside the auger column as described in the report, the use of monitoring the quality of ground water below a known contaminated zone, hollow-stem auger drilling may not be advisable unless protective surface casing can be installed. Procedures used to construct monitoring wells inside hollow-stem augers may depend on specific site conditions and the experience of the driller. To ensure an adequate working space, augers of appropriate inside diameter for the required size well casing and intake must be used.
