The instructor will demonstrate all required outcomes prior to participants demonstrating to the instructor the proper processes for site and soil evaluation.

Soil evaluation identifying characteristics that affect sewage systems.

Understand the general method of how to evaluate soil characteristics that affect water movement.
 Excavate soil pit – depth, location (don’t ruin site)
 Available tools – soil auger, probe
Basic knowledge of how to examine the soil profile and identify
 Major soil structure features (why it is important is covered in soil/water)
 Colour – mottles and gleyed soils (washed out gray) identified high water table or saturated soils (reason saturated/unsaturated flow in previous module)
 Soil texture, make up of sand/silt/clay, don’t count gravel component
 Effect of gravel component
 Where to take sample

 Trial hand texturing
 Lab testing availability and basic knowledge of lab testing method
 Recognize changes in soil horizons and understand effect on sewage system design.
 Soils logging using various soils logs
