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.

Delineation and Remediation of Soil and Groundwater Impacts

XCG was retained by Barnes Group Inc. (BGI) to conduct site assessment and remediation activities at a former automotive component manufacturing facility located at 3100 Mainway, Burlington, Ontario.

Groundwater Remediation and RSC Filing

In 2009, XCG Consulting Limited (XCG) was contracted by Ontario School Boards’ Insurance Exchange (OSBIE) and the Durham District School Board (DDSB) to peer review the investigation and remediation activities at the Sunderland Public School (PS) in Sunderland, Ontario.

Former Dry Dock and Shipyard, Kingston, Ontario

XCG completed an updated Phase One Environmental Site Assessment of this former federally-owned waterfront property in Kingston. The property had been used in the past for a variety of industrial activities including a dry dock, a shipyard, a military reserve with an artillery battery, workshops, a marine railway yard, a foundry, and a sawmill.

Soil Verification Sampling following Removal of Impacted Soil Beneath a Commercial Building

XCG was retained to complete confirmatory soil sampling of the limits of an excavation in the basement of a multi-use commercial and residential building in Toronto, Ontario.

Environmental Remediation of a Brownfield Site Followed by Restoration After a Fire

XCG was retained to conduct the studies necessary to file Records of Site Condition (RSCs) with the Ontario Ministry of the Environment and Climate Change (MOECC) for a brownfield property in Kingston, Ontario, to allow for a change to residential land use. The property was being redeveloped as a 140-unit student apartment complex.

Delineation and Remediation of Soil and Groundwater Impacts

XCG was retained by Atlas Copco Canada Inc. (ACCI) to conduct site assessment and remediation activities at an industrial facility located at 1157 Blair Road, Burlington, Ontario. Previous environmental investigations completed by another consultant identified the presence of elevated concentrations of chlorinated volatile organic compounds (CVOCs) in both the shallow overburden and deep bedrock water bearing zones at the site.
