E-Clay Stabilisation Chelmsford

The 3 hectare site, in Chelmsford, Essex is a former gravel quarry. The contamination originated from infilling with a variety of wastes as well as use by TXU Energy for storage, workshops and vehicle maintenance.

These historical uses have resulted in soil contamination hotspots across the site (plate 1). The identified contamination includes; Arsenic, Cadmium, Chromium, Copper, Lead, Nickel, Zinc, Phenols, PAH’s and TPH.

Following remediation, the site was developed into a housing estate. The development comprised residential housing and flats, with associated gardens and landscaped areas.

The remediation strategy for the TXU site was designed to address the source and indirectly pathway contamination issues, with the intention of protecting both human and groundwater receptors.

Envirotreat employed an ex-situ soil mixing remediation strategy for the treatment of over 2750m³ of contaminated soils.
