What it is	Water Science combines biology, chemistry, physics, and geography to study how water systems work and how to protect them. You'll examine lakes, rivers, and groundwater from ecological and physical angles rather than focusing only on engineering solutions. This program suits students interested in environmental problems who want a science-based approach grounded in both living systems and earth processes.	You study how to manage environmental problems using science, business, and planning tools — combining ecology, land use, and sustainability practices. This program requires a co-op work term, meaning you alternate between classroom and paid work placements in environmental roles, giving you real-world experience alongside your degree. It suits people who want to protect natural systems but also understand budgets, policy, and how organizations actually operate.	You study how the natural world works alongside the human systems that affect it. The BES focuses on environmental policy, conservation, and sustainability through social and geographic lenses, while the BSc emphasizes the physical science side: geology, ecology, and environmental processes. Both paths suit people interested in solving real environmental problems through either policy and community work or scientific research and analysis.
