Long description: Askern Colliery was a derelict colliery and coke works, consisting of two shafts with the associated process and ancillary installations. Many of the former colliery sites have severe soil and groundwater contamination issues and this was also the case at Askern. The coke works closed in 1986 and the colliery shortly afterwards. Geotechnical and contamination investigations commenced in 1993. The contract for the remediation of the site was tendered in 2001 and was won by Mowlem Remediation. The consultant engineer was Carl Bro Group and the bioremediation was carried out by Ecologia Environmental Solutions. Bioremediation was selected as an appropriate technique to remediate the contamination at the site, which was predominantly made up of hydrocarbons. Bioremediation is the use of bacteria to metabolise hydrocarbon contamination and is employed in a variety of technologies. The type of bioremediation used by Ecologia at Askern was biopiles.
