Sometimes it is only necessary to explore the upper 3 m ( 10 ft) of soil. This might be the case for lightweight structures on sites where the soil conditions are good，or on sites with old shallowfills of questionable quality. Additional shallowinvestigations might also be necessary to supplement a program of exploratory borings. In such cases，it can be very helpful to dig exploratory trenches ( also known as test pits) using a backhoe. They provide more information than a boring of comparable depth ( because more of the soil is exposed) and are often less expensive. Disturbed samples can easily be recovered with a shovel，and undisturbed samples can be obtained using hand-held sampling equipment.
Two special precautions are in order when using exploratory trenches. First，these trenches must be adequately shored before anyone enters them ( see OSHA Excavation Regulations) . Many individuals， including one of the author's former colleagues， have been killed by neglecting to enforce this basic safety measure. Second，these trenches must be properly backfilled to avoid creating an artificial soft zone that might affect future construction.
