You have been asked to determine the fate of a contaminant spilled into the following system: Contaminant spilled into lake with a volume of 7x10^6 m^3 Sediment volume: 2.1x10^4 m^3, Sediment foc: 0.05, Sediment density (s ): 2.5 kg/L, Air volume: 6.0 x10^9 m^3 Compound information: Carbon Tetrachloride Kaw : 1.082 Log Koc : 2.18 Density (): 1.59 g/cm3

1) Find the fraction of carbon tetrachloride in air, water, and sediment at equilibrium. Assume no reaction and that the system is closed. Make sure you carry your units throughout the calculation to ensure they work out the way they should

2) If the maximum allowable concentration of carbon tetrachloride in water is 5 g/L and 32,000 L of carbon tetrachloride spills into the lake, will the lake water exceed the allowable concentration at equilibrium?
