Upfront costs for excavation and disposal can be high compared to in situ treatment technologies. Used to construct embankments and foundations, earth usually is easy to move with scrapers or other types of earthmoving equipment. The principal advantage to this option is that much, if Binford notes that all of these activities would have left evidence in the archaeological record, but that none of them would provide evidence for the primary reason that the hunters were in the area; to wait for prey. Finally, there are sites in cliffs and gravel beds where many Paleolithic finds have been made. Water accumulation must be kept to a minimum to reduce risks such as slipping or tripping hazards, electrical hazards, equipment malfunctions or others.

Archaeological material tends to accumulate in events. Equipped with modern technology, they can use GPS to clear and grade land very accurately. Soil remediation is the process of removing or neutralizing that soil, leaving a safe and clean site to build on. Excavations of more than four feet in depth must be tested for all these hazardous accumulations EXCEPT: When choosing a protective system for an excavation, all of these conditions should be considered EXCEPT: Who must ensure that materials and equipment are in good working condition? Durations of removal actions vary widely, depending on factors including volume and accessibility of contaminated media, availability and logistics of waste transport, daily capacity at the receiving facility, and weather.
