  • Operating Refinery in Saudi Arabia

    Vertex Environmental Inc. staff have designed, constructed and operated a series of pneumatic skimmer skimmers for the removal of free phase petroleum hydrocarbons including naptha, gasoline, diesel, fuel oils and crude oil. Geologic environments in which Vertex has installed skimmer systems include fractured rock, glacial till and other unconsolidated materials such as sand, gravel and

  • Trailer Park in Eastern Ontario

    At a trailer park in Eastern Ontario, two heating oil tanks released heating oil into the underlying unconsolidated and fractured media. Following excavation of the unconsolidated material, an in-situ chemical oxidation program was completed to address the petroleum hydrocarbon plume and associated free phase within the fracture rock. BTEX (concentration of 1,920 μg/L) F1 to F4 (concentration

  • Remediate a Former Fuel Storage Facility

    Vertex staff were retained to remediate a former fuel storage facility that was impacted by free product petroleum hydrocarbons. The hydrocarbons had a specific gravity less than water (i.e. LNAPL) and was characterized as being a mixture of diesel and gasoline. The free product was situated within a fractured limestone aquifer and was located within

  • Former Fuel Dispensing Facility in Toronto

    At a former fuel dispensing facility in Toronto, historical leaks from a series of underground storage tanks and pipes resulted in the development of a groundwater plume over an area of approximately 1,000 m . Excavation was deemed to be technically challenging and cost prohibitive. Compounds of concern within the soil included: BTEX (concentration >

  • MPE system in the Greater Vancouver Area

    Vertex Environmental Inc. specializes in the design, implementation and optimization of remedial systems including multi-phase extraction (MPE) systems. Vertex staff designed, permitted, optimized and operated a MPE system in the Greater Vancouver Area for the containment and extraction of petroleum hydrocarbon-impacted groundwater including the extraction of free product. The system was installed in a silty

  • Remediate a Former Fuel Transfer Facility

    Vertex staff were retained to remediate a former fuel transfer facility that was impacted by free product petroleum hydrocarbons. The hydrocarbons had a specific gravity less than water (i.e. LNAPL) and was characterized as being a weathered gasoline product with ethanol additives.
