Chain of Custody Documents

Accurate testing of environmental samples depends on proper curation of the media throughout the collection, transport, and analysis processes. This emphasis is prioritized by ASTM International and the EPA, and our tenured professionals implement daily in their activities within the field, collecting and handling each sample according to protocol. We document each project to ensure samples can be tracked from the field to the laboratory with the necessary quality assurance and accuracy.
