Understand the importance of detailed sampling plans & potential hazards. Learn collection techniques, equipment selection, and recordkeeping for hazardous waste sampling. Includes soil, water, and container sampling procedures.
E N D
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.
Sampling • determine the characteristics of a source material • a sample can come from two sources: • the environment • hazardous waste
Sampling Plan • background information • sample collection details • selection of sampling equipment • PPE
Sampling Plan • decontamination • standard operating procedures • sample integrity • recordkeeping • packaging and shipping
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
Sample Recordkeeping • location information • chain of custody • packaging and shipping
Sample Labeling • sample ID number • date/time of sampling • specific location where taken • name of person taking the sample • the analysis requested
Soil Sampling • surface soil samples • soil sampling at given depths • auger • bucket • continuous flight • post hole • trier • split spoon • backhoe
Surface Water Sampling • pond sampler • bottle sampler • peristaltic pump • Kemmerer bottle
Groundwater Sampling • purging • gas pressure displacement system • submersible pumps • peristaltic pump • bailers
Container Sampling • Opening • Remote-controlled Opening • pneumatically • hydraulically • penetration
Selection of Sampling Equipment • dependent on the type of container • dependent on the material to be sampled
