Soil Sampling Flashcards
Sieve analysis
Often used to classify soils based on particle size
Gravel (2-60mm)
Sand (0.6-2mm)
Silt (0.006-0.06mm)
Clay (<0.002mm)
Soil sampling techniques
Samples should be large enough to be representative of the site (500-1000g)
Compositing over comes cost restriction and lack of homegeniety but may dilute samples of interest
Considerations for site selection/sampling points
Review of site history and background information
Soil sampling program must include:
Pollutants- types and anticipated level Depth to collect samples from Sampling equipment Sample containers Number of samples Analytical parameters: Preservation and sample storage
Soil pollution
Soil pollution in soil typically occurs through the deposition from liquid spills and air borne contaminants.
Sampling equipment
Equipment depends in the migration patterns of the analysts
Shovels
Scoops
Soil punches
Augers
