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.
