The main pollutants from this chemical plant is perchloroethane, pentachloroethane, hexachlorobutadiene and HCB, and such pollutants are present in the soil with high densities, some as high as 1%- 95%, of which the perchloroethane is near the purity of the corresponding product, and especially this part of the soil contains comparatively high-density persistent organic pollutant HCB, which makes it suitable to be disposed of together with other soils. Therefore it is suggest that this part of soil should be separately dug out and transported outside of the site.

The time of the pedogenic process was in the last ice age, therefore this area was colder and drier in climate and lower in sea level than today. The main chemical process in the soil was oxidation, a period of the formation of oxide minerals such as limonite. With the deposition and covering of the marine facies layer in the postglacial period, the soil turned into diagenetic process. Consequently the chemical process in the soil was dominated by reduction and this process was the main development period for nodules of iron-manganese carbonate to form.
