If 2000 L of perchloroethylene were accidentally leaked into the environment and entered the groundwater, how many tonnes of iron would be needed to purify the groundwater using an underground permeable wall? (perchloroethylene density = 1.623 g/mL)
Please see attachment as well so that this can be seen more clearly.
Perchloroethylene, C2Cl4, has molecular mass of 166 ...
