Challenge Problems
Push your limits with challenges.
Question 1
A contaminated sediment layer has a Retardation Factor of 2. If a contaminant moves at 1 cm/day in water, what is its effective speed in the sediment?
💡 Hint: Use the formula: Effective Speed = Speed in Water / Retardation Factor.
Question 2
Given a concentration of contaminants in pore water, how do you calculate the concentration in sediment using the mass balance approach?
💡 Hint: Reflect on how you measure concentrations after extraction.
