XCG has completed a wide range of environmental engineering projects for a diverse group of clients across North America. 

Zero Valent Iron-based Permeable Reactive barrier Design, Construction and Performance Monitoring

XCG was retained by Leggett & Platt Inc. (LPI) to provide engineering services in relation to the investigation of soil and groundwater quality and subsequent remediation of a former industrial facility, located at 66 Jutland Road, Etobicoke, Ontario. Phase I and II Environmental Site Assessments (ESAs) completed by XCG identified the presence of elevated concentrations of chlorinated volatile organic compounds (CVOCs) within the shallow overburden soil and groundwater at the site. To meet LPI’s needs and to manage potential liabilities related to off-site migration of CVOC-containing groundwater, XCG designed a Daramend-based permeable reactive barrier (PRB) along the east property boundary.

Methane Venting System – Construction Management

Based on our previous work on a commercial property that was next to a historical municipal landfill, the new owner of a retail plaza requested XCG to assist with the implementation of a methane protection system. Due to the close proximity of the old landfill, a condition of development was that full protection from possible methane intrusion was to be provided for any and all buildings constructed.

CPU Implementation

Following the filing of a Record of Site Condition (RSC) for a former industrial property in Guelph, Ontario, by another consultant, XCG was requested to assist with implementation of the Risk Management Measures (RMMs) outlined in the Certificate of Property Use (CPU) issued for the site. RMMs including development and implementation of a Soil and Groundwater Management Plan, documentation of installation of hard and fill caps, and documentation of installation of vapour intrusion mitigation system, as well as monitoring of the vapour system following installation.

Risk Based Investigation and Risk Management Measures Implementation

When a prominent Canadian realty management firm was expanding retail developments in their Hamilton, Ontario retail plaza property, XCG was called to quickly investigate the impacts from a historic dry-cleaning operation that occupied the property circa 1965. The chlorinated volatile organic compound (cVOC) impacts from the former dry-cleaning operations were identified and quantified in soil, bedrock, and groundwater.

Investigate/Delineate First, Dig Later (If At All) -Residential Fuel Oil Release Subsurface Investigation

Residential home owners (the Client) noticed drips of fuel oil coming from the bottom of a 910-litre steel fuel oil AST in the basement of their house. They contacted the company that maintains the AST to come and assess/repair the leak. During the tank inspection a section of the tank shell come off, releasing fuel oil to the basement floor.

Engineering Design Services for 2020 Landfill Expansion – Alberta-Pacific Landfill

XCG was retained by Alberta-Pacific Forest Industries Inc. to undertake the detailed design of the 2020 Landfill Expansion at the Alberta-Pacific Landfill (Site). The Alberta-Pacific Landfill is a pulp mill landfill accepting fly ash, grate ash, reject lime, dregs/grits, alum sludge and biosolids wastes from the on-Site pulp plant. XCG undertook the detailed design for the new engineered landfill expansion in 2019 in anticipation of construction in 2020.

Landfill Gas and Greenhouse Gas Reporting – Knockholt Sub-Regional Landfill

XCG undertook a Greenhouse Gas (GHG) Assessment and subsequent reporting for the Knockholt Sub-Regional Landfill (Site) as the Site was exceeding the Environment and Climate Change Canada (ECCC) threshold for GHG reporting of 10,000 tonnes of carbon dioxide equivalents (CO2e) per year.

Stage 2 Final Closure Design – Nanaimo Regional Landfill

XCG was retained by the Regional District of Nanaimo to undertake the detailed design (up to 90%) of the Stage Two Final Closure at the Nanaimo Regional Landfill (Site). XCG undertook the detailed design for this partial closure area in 2018 in anticipation of a construction date of 2019 or 2020.

Due Diligence Investigations

XCG was retained by an industrial services client to conduct multi-site Phase 2 Environmental Site Assessments (ESA) for due diligence purposes as part of a corporate acquisition of several waste management and processing facilities.

Phase I Environmental Site Assessments and Building Condition Assessments at 46 Sites in Ontario and Quebec

The Phase I ESAs and BCAs were required to be conducted in the retail/commercial or quick-service restaurant buildings on 46 properties within Ontario and Quebec. Due to the large number of individual sites, all of which were occupied by tenants, project management and communication between all parties was critical to the project success.

Designated Substances and Hazardous Materials Surveys

XCG Consulting Limited and Cole Engineering Group Ltd. Joint Venture (COLE & XCG JV) were retained by a government agency on behalf of the owner and manager of the facilities to complete Designated Substances and Hazardous Material Surveys (DSHMS), to update the designated substance inventory database, and to serve as a resource for the facilities in the management of their buildings within the project site.

Design, Operations, and Closure Plan, Greater Vernon Recycling and Disposal Facility

XCG was retained by the Regional District of North Okanagan to complete an updated Design, Operations and Closure Plan for the Greater Vernon Recycling and Disposal Facility.
