Envirotreat Technologies Ltd was commissioned by the Galliford Try Group to remediate a former industrial site in Lichfield to enable the site to be developed for residential purposes. The site was contaminated with hydrocarbon pollutants (both within soil and groundwater) resulting from historical activities on the site. Envirotreat addressed the source contamination by carrying out In-Situ E-Clay Stabilisation. Contaminated groundwater was utilised within the treatment process. Key extraction wells were utilised to pump E-Clay slurry into the saturated zone to treat the remaining localised perched groundwater (following completion of the stabilisation works). The remediation works were approved by the regulatory bodies.
