A former industrial chemical manufacturing site was to be redeveloped for industrial and domestic usage. Soil and groundwater had suffered extensive contamination from volatile organic compounds (including benzene and vinyl chloride) over a treatment area of some 20,000 square metres.

TRM constructed an extensive installation of surface laid collection pipework overlain by a purpose built impermeable barrier. The groundwater was sparged under a predetermined regime, which liberated the volatile compounds for subsequent collection and destruction with an automated catalytic oxidiser which was optimised to operate in the auto-therm range.

This specified operating regime achieved efficient and effective remediation of the soil and groundwater. The entire system operated automatically by PLC with remote sensing, data acquisition and remote telemetry.
