Trimodal Soil Distribution
This distribution has a real import. Solusols and vaposols compared to produsols contain substantially less contaminant mass. As such, it is not difficult to exhaust these lesser concentrations of soil contamination. The ... with clean air or clean water, can be accomplished with many fewer flushes since the contaminant mass is 1/100 to 1/10,000 that of produsols. Remember that this figure is ...
