  2. Instructional Goal Through lecture, discussion, and scenario activities, the participant will better understand the need for detailed sampling plan before sampling begins and will see the problems and hazards associated with each type of sampling that may occur on a waste-site.

  3. Sampling • determine the characteristics of a source material • a sample can come from two sources: • the environment • hazardous waste

  4. Sampling Plan • background information • sample collection details • selection of sampling equipment • PPE

  5. Sampling Plan • decontamination • standard operating procedures • sample integrity • recordkeeping • packaging and shipping

  6. Sample Collection Details • mapped locations both on- and off-site samples • number of samples taken at each point • volume of sample taken • type of sample container

  7. Sample Recordkeeping • location information • chain of custody • packaging and shipping

  8. Sample Labeling • sample ID number • date/time of sampling • specific location where taken • name of person taking the sample • the analysis requested

  9. Soil Sampling • surface soil samples • soil sampling at given depths • auger • bucket • continuous flight • post hole • trier • split spoon • backhoe

  10. Surface Water Sampling • pond sampler • bottle sampler • peristaltic pump • Kemmerer bottle

  11. Groundwater Sampling • purging • gas pressure displacement system • submersible pumps • peristaltic pump • bailers

  12. Container Sampling • Opening • Remote-controlled Opening • pneumatically • hydraulically • penetration

  13. Selection of Sampling Equipment • dependent on the type of container • dependent on the material to be sampled
