[20-cm]) borings andsoundings. Both procedures have evolved overa period of 100 and 70 years, respectively, and havebeen adopted as ASTM standards . Each procedurehas certain advantages over the other, but both canelicit incorrect data under particular subsurfaceconditions that are often overlooked, depending onthe experience of field personnel operating or loggingthe tests.
