Water is the foundation of life. But across the globe, water quality is being compromised as communities struggle with population growth, climate change, industrial and agricultural pollution, and other pressures. Ensuring a safe supply of this precious resource is a growing need worldwide, a need that could become the source of increasing geopolitical conflict. This workshop will bring together scholars from a diversity of disciplines — including academic faculty, graduate students, and postdoctoral researchers — whose work is directed toward maintaining, preserving, and improving clean and sustainable sources of water for human use.
