Description :
Composite sampling can be performed by combining soil from several locations prior to analysis. This was a common procedure, but should be used judiciously to avoid skewing results. This procedure must be done so that government sampling requirements are met. A reference map should be created to record the location and quantity of field samples in order to properly interpret test results. Oil testing was often performed by commercial labs that offer a variety of tests, targeting groups of compounds and minerals. The advantage associated with local lab was that they are familiar with the chemistry of the soil in the area where the sample was taken. This enables technicians to recommend the test that are most likely to reveal useful information.
