Remediation of contaminated soils in 3 gasholder bases using multiphase extraction works followed by stabilisation/solidification of soils. This combination of remedial techniques enabled 5,500 m3 of soil to be treated, then retained on site and the site to be beneficially reused. The technologies used minimised the impact of the works on a constrained site and the local highway network. Contaminated water from the works was treated to enable subsequent discharge to the river adjacent to the site.

Stabilised / Solidified material successfully met site specific validation criteria for banded aliphatic and aromatic TPH, BTEX compounds, the suite of 16 PAH compounds, and easily liberatable cyanide.
