Challenge Problems
Push your limits with advanced challenges
A chemical is released into a deep lake with no wind. Describe how the pollutant will spread over time and the mechanisms involved.
💡 Hint: Consider the effects of water movement on diffusion.
In groundwater with slow movement, pollutants are tracked from a source to a well. Explain how molecular diffusion plays a role in this scenario.
💡 Hint: Think about the driving factors for mass transport in low flow rates.
