Question 1.
What defines wet soil?
Show hintHide hint
Think about the saturation condition of the soil.
Question 2.
What is the difference between damp and dry soil?
Show hintHide hint
Consider how water content affects soil properties.
3Question 3.
In a wet soil, where do chemicals mainly bind?
- To mineral surfaces
- To organic carbon
- Neither
Show hintHide hint
Consider the saturation level of the soil.
4Question 4.
True or False: Dry soils have no binding sites available for chemicals.
- True
- False
Show hintHide hint
Reflect on what dry soil means.
Question 5.
A soil sample is found with varying moisture content from wet (saturated) to dry. Calculate the expected distribution of a contaminant introduced into this environment based on the soil’s moisture properties and provide recommendations for remediation based on observed conditions.
Show hintHide hint
Use the moisture definitions and binding behaviors to guide your predictions.
Question 6.
Discuss how chemical partitioning differs in a damp soil that is experiencing intermittent wetting and drying cycles. Provide a theoretical framework for the expected chemical behavior.
Show hintHide hint
Consider the changes in moisture and analyze how this affects chemical properties.
