At completion of the boring to the depth of interest,
the hole may be abandoned or testing or monitoring devices
can be installed. Hollow-stem auger drilling allows for drilling
and casing the hole simultaneously, thereby eliminating hole
caving problems and contamination of soil samples (2). The
hollow-stem auger drilling and sampling method can be a
satisfactory means for collecting samples of shallow unconsolidated
subsurface materials (2). Additional guidance on use
can be found in Refs. 2, 3, 4, 5, 6.
