A contaminated site has 200 kg of chemical A. If the log Koc is 3.5 and the aqueous solubility is 0.5 mg/L, calculate the mass of A that can dissolve in water and the remaining mass in solids.
💡 Hint: Use the solubility as a cap for dissolved mass.
If moisture content in a soil is found to be 0.8, how would that affect the mass balance equations compared to a soil with 0.3 moisture content?
💡 Hint: Analyze how the total mass differs between high and low moisture contexts.
