Abstract: A soil remediation apparatus comprises: a trommel screen having an inlet and an outlet; a trommel screen housing, and air extraction means operable to extract contaminant vapors volatilized by the trommel screen during soil aeration from the housing and to contaminant remediation means, such as a biofilter. The trommel screen housing comprises: a trough in which the trommel screen is mounted with its inlet inclined upwards; a front cover mounted at the front of the trough and having an impacted soil inlet in communication with the trommel screen inlet; a rear cover mounted at the rear of the trough and having a vapor discharge outlet above the trommel screen and a treated soil outlet in communication with the trommel screen outlet, and a vapor cover frame at least partially removably mounted to the trough and a flexible vapor cover removably mounted over the frame.
