The site is in QiLianShan Road 145, Shanghai, China in a 90 000m² field in the city. The location was once occupied by a dying company which spilled various contaminants in the ground. The project is a pilot test on a 25m² at 14m depth (heating zone) with 11 gas burners (V3/V4), a vapor treatment unit and a liquid treatment unit. Construction of the watertight wall In order to isolate the treatment zone from the ground water a wall was built in the...
The site is located at LINDEVANGSVEJ 8, DK 2950 Vedbaek, Denmark. It is a private house located in a residential area, north of Copenhagen. Contamination is partially located by the house under the terrace and mainly in the garden. The target zone is contaminated with mineral oil (C10-C40). The estimation of the diesel amount present in soil are 12000 to 15000 liters and its total mass is estimated to 10800 kg. The soil analysis results showed that the average concentration is...
The project took place in Brussels, in the basement of an office building situated in the heart of the European district. The pollution is due to the leakage of two oil tanks located beneith the underground car park. The soil was polluted with hydrocarbons. An average concentration of 18.000 mg/kg DM. The depth was 14 meters and the total contaminated surface was 50 m². Planning : Mobilization : 4 weeks Treatment : 5 weeks Analyses & reports : 2 weeks Demobilization: 2 weeks The objective of...
The project took place in Italy, in Milan, in front of and behind the existing building on the site. The site is destined to become a parking lot. To access the contaminated area (under the building), a pit (9.7 x 6.6m) was dug, at 3m depth. The treatment began on July 28, 2016 and ended on September 09, 2016, for a period of 43 days. The soil was impacted to a depth of 4.5m by Diesel (C10-C40). Peaks of concentration reached...
The site is located at H&S AVIATION AIRPORT SERVICE ROAD HILSEA PORTSMOUTH PO3 5PJ, on a former aviation site. The project is made on a 243m² heating zone (6m depth) with 7 gas burners and 14 heating pipes. Soil was impacted by Chlorinated Solvents and Kerosene. The figure shows the evolution of recovered contaminants through out treatment time. The figure shows the temperature’s curve through out treatment process. Contaminants’ concentration after treatment was of <1mg/kg DM. All remediation objectives were achieved. Contaminants VOCL Max....
The ISB (International School of Brussels) site is built on a 22.4 m² hot spot contaminated area located directly under the existing building at 9 m depth (bgs). It was estimated that over 4,000 liters of fuel oil were lost, apparently leaking from a damaged existing fuel tank. The ISB (International School of Brussels) site is built on a 22.4 m² hot spot contaminated area located directly under the existing building at 9 m depth (bgs). It was estimated that over...
The site is located at Ixelles, Brussels, rue des Drapiers 26. The pollution is due to a oil tank leaking in the basement of the Association des Carmélites de Saint-Joseph’s building. The remediation area has a ceiling height of 2.5m and the access is only possible by taking the stairs which are <1.5m large. The room is ventilated by a small window which will be able to welcome the evacuation network for the combustion gases, with connection to the boiler room.The...
The area to be cleaned is located in the southwest corner of a courtyard inside the building of the Saint Joseph Institute. It is located close to a high-voltage cabin located in the southwest corner of the courtyard. It is surrounded by builvdings of several floors. An average concentration of 1000mg / kg for a maximum of 2000mg / kg of mineral oils contamination was detected in the soil, for a total volume of 65m3. It represents a polluting load...
The Equipment and Transport Administration of the Brussels Region, the project manager, was faced with TPH contamination at the DELTA site. This site comprises an underground station, an underground metro depot and a bus depot. Twelve single-wall metal tanks were buried on the site and showed signs of leakage. Mourik, the main contractor, carried out 6 meter deep excavations and removed the tanks. Further excavations were prohibited because of questions of the stability of the building. Deep Green was then chosen...
Thermal desorption of 21,000 tons of contaminated soil coming from the Homecourt gaswork site by means of a mobile unit. The site was a previous cokeswork, which will be reaffected into small business area. The cokesworks were owned and operated by USINOR (Group ARCELOR), and the company decided to clean-up the site before reusing it through the local community. The contaminated soils held PAH concentrations in excess of 9,000 ppm with average concentrations at 3,200 ppm. The project was done with...
