A barge spills chlorinated solvent into a river. Describe the expected behavior of the solvent and the implications for sediment.
💡 Hint: Consider the properties of both the solvent and the river's flow.
Calculate the flux of a DNAPL from sediment to water given the concentration in sediment as 200 mg/L and equilibrium concentration in water as 50 mg/L with a mass transfer coefficient of 0.1 cm/s.
💡 Hint: Think about what a negative flux can imply in terms of movement.
