contaminant transport assessment
Understanding the fate and transport of existing or potential contaminants is essential to managing risk, choosing appropriate remedial solutions, and designing treatment systems.
Geofirma develops and implements field programs to collect the hydrogeological data required to assess contaminant transport. Our team has a depth of knowledge in designing and supervising the drilling of shallow and deep boreholes to collect relevant geological, hydrogeological and geochemical data. This data is analyzed and synthesized to develop defendable conceptual flow and transport models. Our numerical modelling team, with many decades of experience, uses models appropriate to the given problem, ranging from simple analytic models to complex two and three-dimensional models of groundwater flow, gas flow and contaminant transport.
Example projects include:
In a continuous series of projects over the last 25 years, we have supported the assessment of the long-term fate and transport of radionuclides at potential deep geologic waste repositories for nuclear waste in Ontario.
A multi-year litigation support project assessed potential sources of chloride contamination near an operating landfill.
Detailed groundwater flow and contaminant transport simulations to assess the performance of the proposed permanent decommissioning of a de-fueled nuclear reactor.
A multi-year assessment of bedrock aquifers in Manotick, Ontario, which were contaminated by a former dry-cleaning facility.
Protection of the City of San Diego’s interests by reviewing proposals for site cleanup of a large gasoline release, analyzing data, conducting simulations and proposing approaches for remediation.
