Remediation
Ozone Sparging – Staffordshire
Ecologia has completed a project in Staffordshire to remediate petrol contamination to groundwater following a substantial loss from an underground storage tank (UST). The petrol contamination was found to have migrated beneath several domestic properties, leading to an indoor vapour inhalation risk pathway.
Multi-Phase Extraction – Northern Italy.
Ecologia was appointed to design, manufacture and install a Multi-Phase extraction system at a chemicals facility in Northern Italy. The remediation contracting was undertaken by Ecologia following investigation and overall design by various consultants.
Automated Ex-Situ Bioremediation – Verona Gasworks
Bioremediation is a technique with good sustainability credentials. Ex-situ bioremediation comes in several guises and the specific form of ex-situ bioremediation that Ecologia use is Biopiles. Biopiles are engineered piles of soil that include active aeration of the soil using a vacuum blower, collection of leachate and allow the abatement of VOC’s possible by
capturing the extracted gases. Biopiles operate very quietly with comparatively little operation and maintenance required.
Air Sparging – Norwich, Norfolk
Ecologia was contracted to remediate a residential property just outside Norwich after an attempted theft of domestic heating oil from an above ground oil storage tank. This resulted in approximately 1,900 litres of kerosene impacting the underlying soils and groundwater.
Source Excavation and Soil Vapour Extraction in The Chalk
Ecologia was contracted to assess and remediate a site where approximately 1500 litres of heating oil had leaked into the Chalk aquifer upgradient of a major public water supply abstraction.
The site presented a number of difficulties, being located on a steep gradient and immediately adjacent to a residential property. Groundwater was known to be at depth within fractured Chalk, but limited data was available about the hydrogeology.
Multi-stage, Mobile Oil/Water Separator
The system incorporates five stages of operation into one unit.
Dual Phase Extraction & BioSparging – Hampshire
A loss of 2000 litres of heating oil occurred adjacent to a grade A chalk stream in Hampshire. The property is located on a chalk stream flood plain. The flint gravels underlying the site allowed the rapid migration of the oil to the chalk stream, which runs through the garden of the property.
Ecologia undertook a detailed survey to assess the spread of the contamination and to delineate the plume. The plume was found to have migrated beneath an engineered section of the river to the opposite side. Free product was also found to have migrated beneath a listed building which precluded excavation of the contaminants. A traditional dual phase extraction system would not be effective in the highly permeable gravels, so the development of an innovative technique was required.

Air Sparging – West London
Following a loss of a significant quantity of kerosene from an above ground storage tank inWest London, Ecologia were initially contracted to remove free phase oils form the surface of the groundwater. This work was undertaken by Ecologia within 4 months of instruction.
