| in situ Application of potassium permanganate to treat impacted groundwater at an industrial warehouse site, Brantford, Ontario The operation of a warehouse facility resulted in soil and groundwater impacts in the vicinity of the loading docks of the facility. The client has excavated the source soil contamination and the groundwater was remediated using in situ application of potassium permanganate using Terratechnik's mobile in situ treatment system. |
| Ex situ treatment of contaminated groundwater during soil excavation, Greater Napanee, Ontario A former industrial site has petroleum impacted soil and groundwater. An ex situ treatment of the contaminated groundwater is to be operated during the excavation and backfill processes. The groundwater is to be filtered to remove sediment and petroleum hydrocarbons (via carbon filtration). |
| In situ chemical oxidation with ex situ treatment using a multiphase extraction system to extract impacted groundwater and migrant vapours, Kingston, Ontario A commercial site has chlorinated solvents found in the groundwater. A series of injection and extraction wells were installed to facilitate the distribution of potassium permanganate across the site. A multiphase extraction system was installed to extract impacted groundwater and migrant vapours. |
| Installation and Operation of a Soil Vapour Extraction System for the Abatement of Migrant VOC Vapours within occupied interior spaces (retail site), Toronto (Etobicoke), Ontario The installation of screened wells and a manifold system connected to a soil vapour extraction unit is successfully managing the potential health risk posed by migrant vapours of chlorinated VOCs on-site. The site will operate until the completion of the groundwater remediation process. |
| Ex situ remediation of contaminated soil and groundwater at a commercial site, Greater Napanee, Ontario A commercial site has petroleum hydrocarbon impacts in the soil and groundwater on the footprint of a former gas station. The contaminated soil is to be excavated and removed. During the backfilling process, oxygen releasing compounds, which promote an oxidative environment, are to be included with the fill material. An additional reactive barrier (containing a geomembrane liner) is to be installed downstream of the contaminant plume with oxygen releasing compounds included in the fill material. Extraction and injection wells are to be installed to apply the oxygen releasing materials in situ if required. |
| In situ remediation of chlorinated VOCs and petroleum impacted groundwater (commercial site), Toronto, Ontario A commercial property, historically the site of painting and manufacturing facilities, has chlorinated VOCs (PCE, TCE, DCE, VC) in the groundwater in excess of 23,000 ppb total VOCs and TPH in the soil and groundwater in excess of 1,000 ppm and 5,000 ppb respectively. Destruction of TCE and its break down products to below MOE table B criteria will be achieved via the in situ application of potassium permanganate. The petroleum hydrocarbons will be remediated in situ applying a combination of Fenton’s reagent and bioremediation. Remediation timelines are expected to be dramatically reduced due to the operation of a pump and treat system with an on-site ex situ groundwater treatment component. |
| Application of Fenton's chemistry to remediate petroleum impacted soil at a residential site, Toronto, Ontario A residential property was found to have petroleum impacts after an underground storage tank (UST) for fuel oil was removed.

| Application of limiting nutrients to facilitate the bioremediation of soil contaminated by the release of fuel oil from underground pipe, Oakville, Ontario The soil at the footing of an industrial pier was contaminated with fuel oil after an underground pipe was found to be leaking into the soil. Soil bacteria was taken from the site, isolated, grown and reintroduced with limiting nutrients to aid in the metabolism of the fuel oil. |
| in situ remediation of chlorinated VOC (perchloroethylene, trichloroethylene, trichloroethane, dichloroethylene and vinyl chloride) impacted and petroleum impacted groundwater (commercial site), Toronto, Ontario At a site historically used as a manufacturing facility, the soil and groundwater was impacted with PCE, TCE, TCA, DCE, and VC in excess of 7000 ppb total VOCs. Source zone contamination was excavated and disposed off-site while recovered groundwater was treated ex situ via a groundwater filtration system. In situ destruction of residual VOCs was promoted through the injection of hydrogen releasing compounds (HRC) and limiting nutrients to stimulate biodegradation. In addition, a geosynthetic clay liner was installed at the property boundary thus preventing the potential movement of any residual contaminants prior to site closure. |
| in situ remediation of chlorinated VOC impacted impacted groundwater (commercial site), Toronto, Ontario At a site historically used as a manufacturing facility, the groundwater was impacted with the break down products of trichloroethylene including cis-1,2-DCE and vinyl chloride in excess of 1300 ppb and 630 ppb, respectively. Destruction of the contaminants of concern to below MOE table B criteria was accomplished with the in situ application of an oxidizing agent (potassium permanganate). Destruction of the contaminants of concern to below MOE table B criteria was accomplished within recovered groundwater ex situ in reactor vessels through the application of Fenton's reagent. |
| in situ remediation of TPH (gas/diesel) impacted soil and groundwater (commercial site), Newmarket, Ontario The operation of a petroleum dispensing facility resulted in the impact of the soil beneath a structure with petroleum hydrocarbons at concentrations exceeding 2,000 ppm. In situ chemical oxidation through the application of Fenton’s Reagent resulted in a reduction of TPH to below MOE table B criteria. |
| In situ remediation of chlorinated VOCs impacted groundwater (brownfield site), Toronto, Ontario At a site historically used as a manufacturing and warehousing facility, the groundwater was impacted with trichloroethylene (TCE) in excess of 1500 ppb. Destruction of TCE and its break down products to below MOE table B criteria was accomplished with the in situ application of an oxidizing agent (potassium permanganate). Remediation was expedited with the aid of a pump and treat system with an on-site ex situ groundwater treatment component. |
| In situ remediation of TPH (gas/diesel) impacted soil (residential development), Toronto, Ontario The operation of several fuel oil USTs resulted in the impact of a silty clay till soil with petroleum hydrocarbons at initial concentrations of >8,000 ppm gas/diesel. Chemical oxidation with the in situ application of Fenton’s Reagent, followed by bioremediation, resulted in a reduction of TPH to below MOE table B criteria. |
| In situ remediation of TPH (gas/diesel) impacted soil (residential development), London, Ontario During removal of a fuel oil UST, excavation of all petroleum hydrocarbon impacted soil could not be accomplished without undermining the adjacent building. Soil with initial concentrations exceeding 20,000 ppm gas/diesel was remediated, with the application of hydrocarbon degrading bacteria and limiting nutrients, under aerobic conditions to below MOE table B criteria. |
| Pilot Scale Remediation: In-situ remediation of chlorinated VOC impacted soil and groundwater (operating manufacturing plant), St. Thomas, Ontario A leaking AST located within a machine parts manufacturing plant resulted in perched groundwater and soil impacted with trichloroethylene (TCE) in excess of 3300 ppm. The destruction of TCE and its break down products (dichloroethylene and vinyl chloride) within the treatment pilot area was accomplished to the clients satisfaction with the in situ application of an oxidizing agent (potassium permanganate). Remediation was expedited with the aid of a pump and treat system with an on-site ex situ groundwater treatment component. |
| Ex situ remediation of TPH impacted soil, Waterdown, Ontario Excavated soil impacted with petroleum hydrocarbons at initial concentrations of >8,000 ppm gas/diesel and >15,000 heavy oils were remediated to below MOE table B criteria. The treatment strategy included the ex situ application of petroleum degrading bacteria and limiting nutrients under aerobic conditions. |
| In situ remediation of TPH and VOC (iso-propyl alcohol, acetone, perchloroethylene, and toluene) impacted soil and groundwater (industrial warehouse site), Toronto, Ontario The in-situ bioremediation of TPH (gas/diesel) and VOC impacted soil and groundwater was facilitated by injection of Fenton’s Reagent for chemical oxidation. The impacted soil existed beneath an industrial warehouse building. The remediation system was designed to minimize site disruption and allow the client to carry on site activities during the remediation. Remediation resulted in an approximate mass reduction of 95% in VOC concentrations which were originally greater than 780, 000 ppb. |
| In situ remediation of TPH impacted soil (residential high rise apartment), Toronto, Ontario The operation of a fuel oil UST resulted in the TPH (gas/diesel and heavy oil) impact of soil quality. Initial TPH concentrations were greater than 10,000 ppm gas/diesel and greater than 30,000 ppm heavy oil. The client had excavated as much soil as was feasible, but could not continue excavation activities underneath a large boiler. In situ remediation with chemical oxidation using hydrogen peroxide resulted in remediation of TPH to below MOE table B criteria. |
| In situ and ex situ remediation of TPH impacted soil, Toronto, Ontario Soil and groundwater impacted with petroleum hydrocarbons at initial concentrations of greater than 5,000 ppm gas/diesel and greater than 10,000 heavy oils were remediated to below MOE table B criteria.
