Site & Soils Field Training (Estevan)
April 21, 2017
Estevan, SK
A site and soils field training day is being planned for Estevan. This is a live site, so a few weeks following the site and soils evaluation, a system installation will also take place. During the course of the field day, participants will focus on soil evaluation identifying characteristics that affect sewage systems, including:
- Understanding the general method of how to evaluate soil characteristics that affect water movement.
o Excavation of the soil pit – depth, location (don’t ruin site)
o Available tools – soil auger, probe
o Basic knowledge of how to examine the soil profile and identify
o Major soil structure features (why it is important is covered in soil/water)
o Colour – mottles and gleyed soils (washed out gray) identified high water table or saturated soils (reason saturated/unsaturated flow in previous module)
o Soil texture, make up of sand/silt/clay, don’t count gravel component
o Effect of gravel component
o Where to take sample
o Basic hand texturing procedures
o Trial hand texturing
o Lab testing availability and basic knowledge of lab testing method
o Recognize changes in soil horizons and understand effect on sewage system design.
o Soils logging using various soils logs
o Understanding and application of the soil texture triangle.
o Ability to determine effluent-loading rate for a soil texture set in Standard of Practice.
o Knowledge of restricting/limiting layers and ability to recognize major characteristics.
o Ability to recognize major soil characteristic and determine soil effluent loading rates or limitations.
