FEATUREd PROJECTS - CHEMICAL OXIDATION
Environmentally responsible chemical oxidation technology is capable of eliminating a wide variety of industrial pollutants from TCE’s to heavy metals.
Chemical oxidation is not limited by soil conditions or temperature and has been effective throughout the harsh Canadian winter.
Our process is environmentally responsible and leaves bi-products such as oxygen and microbe degradable elements. The proprietary catalyst enables the oxidation product to eliminate the contaminant without going exothermic and remaining within acceptable ph levels, avoiding soil damage.
This advanced chemical oxidation technology is not only environmentally responsible but cost effective and time efficient. Browse our featured projects to see the possibilities of our chemical oxidation remediation programs.
FORMER GARAGE PROPERTY, BARRIE ONTARIO
SITUATION
• Property operated as a used car lot and garage for over thirty years and was being redeveloped as a fast food outlet.
• Previous environmental site assessments delineated 1,200 tonnes of petroleum impacted soil and groundwater. Initial TPH (F1 to F2 fractions) concentrations in the groundwater exceeded 14,000 ppb.
• Previous remediation programs were unsuccessful.
TASK
• Implement an in-situ remediation program.
• Forty injection wells were installed in the areas of impairment.
RESULT
• Oxidation product reduced PHC levels to meet MOE Table 2 Regulatory criteria for commercial / industrial land use.
• Regulatory compliance was achieved within 60 days of project start up meeting all stakeholders’ timeframes.
FORMER INDUSTRIAL PROPERTY, SCARBOROUGH ONTARIO
SITUATION
• A former underground storage tank had leaked for many years and soils were contaminated with BTEX and the F1 and F2 fractions of TPH.
• Previous environmental site assessments were completed by other consultants. A vapour recovery system had been installed but it had failed.
TASK
• Oxidation product was injected into four existing injection wells.
RESULT
• This was to be a pilot project, but within 96 hours of injection, PHC levels were reduced to 90% of initial concentrations.
• The site remediation was completed to meet Ontario Ministry of the Environment (MOE) Regulation 153, Table 3 criteria for commercial / industrial property use criteria.
FORMER SERVICE STATION, SIMCOE ONTARIO
SITUATION
• Abandoned underground storage tanks were encountered during the redevelopment of this property. Soils impacted by PHC were removed during the tank removals.
• Groundwater near the property boundary and along the service trenches was impacted by PHC.
• In order to meet the stakeholders’ schedules and budget we were required to work through sub-zero Canadian winter conditions.
TASK
• A series of three injection wells were installed at the property boundary, near the service trenches. Oxidation product was injected into the wells.
• Oxidation product treated the impairment during sub-zero temperatures.
• Due to the high contamination levels, three injection events were required to achieve Regulatory criteria.
RESULT
• The site remediation was completed to meet Ontario Ministry of the Environment (MOE) Regulation 153, Table 2 criteria for commercial / industrial property use criteria.
• Site closure was achieved within 47 days.
FURNACE OIL SPILL, TICHBORNE ONTARIO
SITUATION
• A furnace oil spill occurred at a residential property. The hydrocarbon plume migrated through the shallow surfical soils into the bedrock.
TASK
• A series of eight injection wells were installed in the bedrock. Oxidation product was injected into the bedrock.
RESULT
• Oxidation product reduced hydrocarbon levels to meet Regulatory criteria in one injection event.
• Closure of the project was achieved in 10 days.
INDUSTRIAL SITE, TORONTO ONTARIO
SITUATION
• An industrial site with subsurface soils containing fill materials that were contaminated with PHCs (F2 and F3 fractions) and PAH (benzo(a)pyrene).
• Soils across the entire property required excavation to 3.6 m below grade.
• Three month deadline for treatment of 20,000 tonnes of impacted soil.
TASK
• Two variant oxidation products were applied to the contaminated soils. This process was less expensive than conventional landfill practices.
• Treatment of the impairment took place during sub-zero temperatures, on time, meeting all stake holders’ criteria.
RESULT
• Test results have confirmed that 100% of the treated soils meet Ontario Ministry of the Environment (MOE) Regulation 153, Table 3 criteria for industrial / commercial land use criteria.
• The treated soils were transferred to the clean fill site.
INDUSTRIAL PROPERTY, BURLINGTON ONTARIO
SITUATION
• This site is an established industrial property which could not be sold until remediation was completed.
• Two previous environmental remediations were unsuccessful, delaying site closure.
• Soil and groundwater on-site was impacted with VOCs and PHC associated with former industrial operations.
• Native soils are tight clay with a permeability of 10-9 cm/sec.
TASK
• Sixty injection wells were installed in the area of impairment.
• Multiple injections of two variant oxidation products were required due to the dense clay soils on-site.
RESULT
• Regulatory criteria and project closure was achieved to meet stakeholders’ real estate deadlines.
• The site remediation was completed to meet Ontario Ministry of the Environment (MOE) Regulation 153, Table 3 criteria for commercial / property use criteria.
