  20. 20. In situ bioremediation of TCE (1)Project: Old metal manufacturing plant • Between 1962 - 1985 PCE and TCE were used to wash grease from metal items before painting. • PCE and TCE are toxic, carcinogenic and environmentally harmful • In 1995 the emission was first found during property due diligence. • Contaminated area is over 80 ha.

  26. 26. In situ bioremediation of creosote (1)Project: Old creosote impregnation site • Between 1902…1920 - 1982 creosote was used to impregnate railroad sleepers • Creosote is toxic, carcinogenic and persistent • In 1959 first phenol emission was first found • In the final years creosote was still used around 1300 t/a • The contamination has spread to the municipal GW extraction plant.
