e9dd6711_Soil_sampling__RISK_CONTROL
[SPECIFIC JOB STEPS] Place sample either directly into a sampling bottle if testing for volatiles, or into a mixing tray if sampling for metals. Place into transportation container. Record sample details on a chain of custody form, as specified in SFM2-159 Collecting, Preparing, Storing &Transporting Samples. Include a unique sample identifier, location, container type and requested analysis. [RISK ASSESSMENT] Some metals such as mercury may be present in particulate or droplet form, not evenly distributed in the sample. The laboratory receiving them may sample a ‘clean’ part of the sample, missing the contaminant or getting unrepresentative readings. [RISK CONTROL] 
Mix sample in tray well, to distribte the contaminant evenly, so that the laboratory may analyse a representative sample. Transfer to sample bottle.
