In-Situ Radio Frequency Heating (ISRFH) – Manston, Kent.

Total UK appointed Ecologia to carry out a remediation assessment for In-Situ Radio Frequency Heating (ISRFH) at a former service station located in a groundwater vulnerable area (overlying a Chalk aquifer) in Manston, Kent. The contamination was mostly associated with Petroleum Hydrocarbons and confined within unsaturated Chalk strata, approximately 10 m below ground level (mbgl). For this site ISRFH electrodes were deployed in a triangular array between 3m and 6 m bgl together with eight multilevel SVE extraction wells. The site is typical of a decommissioned medium sized service station in an area with high groundwater vulnerability. The remediation was performed in six Stages in order to demonstrate the added benefits of coupling ISRFH to a traditional SVE system.
