Before field treatment, the contaminated soil was sampled, characterized and tested with
different stabilizers at our laboratory. Soil was taken from the site at two separate times.
In the first series, soil was taken from six surface locations (0–10 cm) and was uniformly
mixed. Laboratory tests were used to find the most effective reagents; analytical grade
chemical reagents were used.In the second series, the site was divided into three different
layers according to depth: a top layer (0–40 cm), a middle layer (40–80 cm), and a bottom layer (80–120 cm). Soils were taken from four locations within the site. The preferred industrial
grade reagents were applied to the soil to determine the optimal dosage for field
treatment. The characterization of the soil followed standard procedures and results are
listed in Table 1.
