Silvia Mancini is a Senior Principal Geoscientist based in Ontario with more than 16 years of experience focused on innovative solutions in site characterization, water management, treatment on mining and metals, manufacturing, oil and gas, and legal sectors.


While Silvia's client service spans several sectors, she specializes in working hand-in-hand with her clients to develop water management and site closure strategies including identifying, testing, and bringing innovative technologies to implementation at challenging sites. Silvia’s experience includes the treatment of challenging constituents such as selenium, nitrate, cyanide, herbicides, pesticides, solvents, and hydrocarbons.

Silvia has helped her clients direct and manage remediation programs using technologies such as passive and semi-passive water treatment systems, in situ bioremediation, Compound-Specific Isotope Analysis (CSIA), in-situ chemical oxidation (ISCO) injections, smouldering combustion (STAR), and permeable reactive barriers (PRB). Through the application of passive and semi-passive water treatment technologies, she supports clients with finding appropriate solutions acceptable by regulatory agencies that can be applied cost effectively and at sites with remote considerations or power limitations. Gravel Bed Reactors (GBR), engineered wetlands, in situ biotreatment, and permeable reactive barriers are examples of technologies which can be considered at these challenging sites. CSIA, the subject of Silvia’s doctoral research, can be used as an environmental forensics and diagnostic tool to evaluate sources and understand degradation mechanisms of constituents of interest. As a subject matter expert in CSIA, Silvia provides expert opinions and peer reviews in legal matters where isotope geochemistry is applied as a line of evidence for source differentiation or remedial performance. Silvia participates as an expert on several advisory panels for mine water management and treatment, and supports international, multidisciplinary projects involving multiple consultants, engineering firms, regulatory, rightsholders, and client stakeholders.

To advance the state of the practice, Silvia maintains active involvement in teaching and research initiatives through university collaborations and her Adjunct Professorship at the University of Toronto, Department of Earth Sciences. She has published more than 17 articles on biotreatment of metals and inorganics, bioremediation of organic contaminants in groundwater and the use of isotope geochemistry at contaminated sites. She also continues to manage government research programs focused on innovative technologies. These programs include the Natural Science and Engineering Council of Canada (NSERC) as well as the U.S. Department of Defense Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP).
