Lattice Property Holdings soil washing project

Lattice Property (formerly BG Property) completed full-scale remediation of 200,000t of contaminated material at Basford Gasworks in 1998 using soil washing equipment owned and operated by Linatex Heijmans.

Ground underlying the site was predominantly granular, consisting of highly permeable river sands, gravels and Sherwood Sandstone, a major aquifer. Principal contaminants were ammonia, phenols and polycyclic aromatic hydrocarbons (PAHs).

Some 76% of the total excavated volume was recovered for re-use.

Completed in 1998, rigorous documentation and high quality information has meant Basford Gasworks remediation was accepted as a retrospective CL: AIRE project. The report is due out in March.
