Abstract

Personnel from the Analytical Chemistry Services Group (ACSG), Mineral Resource Survey Program, formed a team to determine the policies for acceptance and analysis of geochemical samples. This team contacted law enforcement agencies that handle litigious samples, laboratories that work with samples of special nature, and the Solicitor General, Department of the Interior. Using the knowledge from these agencies as well as the expertise of ACSG personnel, sample control routine procedures, sample control evidentiary procedures, personnel policy governing chain-of-custody samples, and the general polices governing physical security of chain-of custody samples have been enacted.
