Envirotreat Technologies Ltd was commissioned by Mar City Homes to remediate a contaminated site in Mill Street, Great Bridge, West Midlands – Mar City Homes are intending to redevelop the site for residential use. The site was contaminated with hydrocarbon pollutants (resulting from former industrial activities on the site). Envirotreat proposed an integrated treatment solution to achieve the remediation objectives – this treatment approach comprised the installation of an E-Clay Permeable Reactive Barrier (circa 200m in length) combined with targeted in-situ ‘hot-spot’ treatment (circa 800m3). Regulatory approvals were obtained from the Local Authority and the Environment Agency. The remediation works were carried out over a four-week period and were completed successfully.
