Seven Steps of the Sampling Process

Based on the information gained from the SAP, we will identify the types and quantities of the needed sampling equipment and supplies (Step 2). A thoughtfully 

Completing field documentation (Step 5), such as the Chain-of-Custody (COC) Form, field logs, and sampling forms, is a separate and distinctive step in the sampling process. Field documentation establishes the basis for informed data interpretation and efficient and accurate report preparation. The COC form is usually the only written means of communications with the analytical laboratory. It also serves a legal function by documenting the chain of individuals, who were responsible for sample integrity. 

Packaging the collected samples for shipment (Step 6), a tedious task as it may be, requires a certain level of experience. Improperly packaged samples are often broken in transit insufficient quantities of ice do not provide the proper temperature control—all of these events have a potential to invalidate the collected samples and, in fact, are a common cause for resampling. 

After the samples have been packaged, they are shipped to the laboratory (Step 7). Samples must reach the laboratory in the shortest period of time possible, as any delays in transit jeopardize temperature conditions inside the shipping container and erode sample holding time. Incorrect information on shipping labels and lack of coordination with the delivery service are known to cause delays of sample delivery to the laboratory.
