Rob is a senior hydrogeologist providing senior technical review and project management services for municipal and mining Environmental Assessments and Environmental Impact Studies, land development projects, infrastructure construction dewatering, and environmental monitoring and compliance for construction projects.
Rob was a former shareholder and senior hydrogeologist at Gartner Lee Limited and manager of the Greater Toronto Area Water and Natural Resources team at AECOM before joining PECG in 2013 to establish the Toronto office. Rob’s experience brings together in-depth knowledge of fractured bedrock and Quaternary hydrogeology, with an understanding of the environmental permitting process and the ability to devise clever, innovative solutions to solve problems. Rob is well respected by permitting agencies and has extensive experience working with various stakeholder groups to permit difficult projects. Rob has managed environmental approvals and hydrogeological peer review studies for several high-profile water supply infrastructure and construction dewatering projects. Predicting and mitigating the influence of construction and mining dewatering on groundwater flow, and the supported sensitive natural features and groundwater resources, are a particular focus of Rob’s work.
Rob’s experience in the nuclear waste sector has also led him to present key results of his work to the Canadian Nuclear Safety Commission, Ontario Geological Survey, and U.S. Geological Survey in support of Ontario Power Generation’s Deep Geological Repository Environmental Assessment.

Permits To Take Water (PTTW)
Pumping Test Analysis
Site-Specific Water Budgets
Jason is a Professional Geoscientist (P.Geo) specializing in hydrogeological investigations in support of design and permitting for large infrastructure, land development and mining projects. His work focuses on characterizing the geological and hydrogeological conditions through monitoring well installations, hydraulic testing, and groundwater/ surface water interaction assessments, to both understand how the project may impact the natural environment and how the groundwater conditions will affect design, construction and permitting.
Through Jason’s diverse project experience, he has also led teams of environmental professionals in watershed management planning and environmental baseline studies.
Jason has both a Bachelor of Science degree and a Master of Science degree specializing in Physical Hydrogeology from the University of Waterloo.
When he is not working, Jason enjoys backpacking, walking his dog Abbey, cooking and travelling the globe with his wife.
Sarah Alloisio Ph.D., P.Geo.
Environmental Impact Assessments
Mine Water Management
Sarah Alloisio is Professional Geoscientist with over two decades of international experience in Hydrogeology, which she developed working with several environmental and engineering consulting companies (including Fluor, Montgomery Watson, Water Management Consultants and Schlumberger) in Canada, South America and Europe, and by running her own company (Fresh Water Solutions) in Vancouver, Canada.
Sarah has a BSc in Environmental Science from the University of Milan, Italy, and a PhD in Hydrogeology and Groundwater Modelling from the University of Birmingham, United Kingdom. She has worked on a variety of groundwater projects for clients in the natural resource, environmental protection and water supply sectors, which include environmental assessments, baseline characterizations, groundwater resource investigations and the design of mine water management systems. Her work was completed in diverse environmental settings, including the Chilean Atacama desert and Thar desert of Rajasthan, the Peruvian Andes, the permafrost of Northern Canada and the Amazon Rainforest. She has expertise in the characterization of bedrock aquifers, including sandstone, karstic limestone, altered intrusive and volcanic units, and of complex unconsolidated groundwater systems. Her professional experience has a strong focus on groundwater modelling, from conceptualization to water budgets and numerical model development, to technical support and training.
Sarah is passionate about the wilderness and heads out camping and canoeing with her husband and daughter whenever she gets the chance.
