Description:
The USEPA evaluated an in situ application of a soil amendment process at a residential site that was contaminated with lead. The goal of the evaluation was to determine if the soil amendment process resulted in lower concentrations of bioavailable lead in the contaminated soils. The relative bioavailability of lead (bioaccessible lead) was measured by an in-vitro test procedure that involves a highly acidic extraction procedure to simulate human digestive processes. Although the results of the soil amdndment process reduced the mean bioavailable lead concentration differences between untreated and treated soils by 11.2%, the differences were not statistically different.
