Previous site activities contaminated alluvial soils at the former coking plant in the Czech Republic with black coal tar, PAHs, and heavy metals. About 1.5 million tons of contaminated soils within three contaminated geological layers were remediated using ex situ thermal desorption. Of the 12,200 tons of contaminants removed, 67.94% were non-polar extractable substances (NPES), 12.25% was benzene, 11.27% was naphthalene, 1.11% was PAHs, 1.11% was benzo(a)pyrene, 0.82% was phenol, 0.16% was arsenic, and and 0.02% was mercury. Thermal desorption contributed to the removal of 90.65% of NPES, while the remainder required offsite disposal.
