Like many Ontario cities, Kingston was once fueled by coal gas. The manufacturing process resulted in deep bedrock contamination beneath parts of the downtown core. Geofirma was retained to complete all aspects of assessment and remediation in the DNAPL source zone for the City.
The Ontario Ministry of the Environment contracted Geofirma to supervise site remediation activities and complete detailed hydrogeological investigation at a former fuel outlet in eastern Ontario. A groundwater plume from the site had impacted domestic wells and surface water.
The City of Ottawa retained Geofirma to conduct several Phase One and Phase Two Environmental Site Assessments along the Ottawa Light Rail Transit tunnel alignment. The investigations were conducted to satisfy environmental due diligence and establish baseline environmental conditions prior to leasing various properties for construction.
The National Capital Commission hired Geofirma to conduct a multi-year baseline study to assess the historical and current environmental impacts of regular fireworks at Casino du Lac-Leamy on the lake waters and sediments, and to conduct a sampling program to assess, monitor and protect the quality of the aquatic habitat of the lake.
Geofirma’s role is to protect the City of San Diego’s interests by reviewing proposals for site cleanup by the responsible party, analyzing geochemical data, conducting simulations, and proposing approaches to improve the success of the aquifer remediation.
Geofirma worked with South Nation Conservation Authority to develop an Aquifer Capability Screening Tool (ACST) for the City of Clarence-Rockland. This tool will be used to pre-screen potential water quantity and quality concerns for privately-serviced lots.
Improving Abandonment ProcessesIn 2016, the Canadian Society for Gas Migration, with funding from Natural Resources Canada, initiated a Technology Roadmap to Address Wellbore Leakage. Geofirma developed the wellbore abandonment section, presenting a high-level overview of the methods and materials used to plug and abandon wells, a synopsis of current research, and the issues that impede the adoption of new technologies to improve abandoned wellbore integrity.
