Purpose

Soil profiles are influenced by five separate yet interacting factors: parent material, climate, topography, organisms, and time. These factors can give soil profiles distinctive character.

The Physical Evidence Bulletin (PEB) is a guideline intended for law enforcement agencies to follow when submitting evidence to Bureau of Forensic Services (BFS) Laboratories. Physical Evidence Bulletins are not intended to be used in lieu of training in the collection of evidence.
