Of this, 504 billion liters daily comes from surface sources, and that water is conveyed over a total distance of 27,000 km.

New report examines water security in U.S. water scarce regions

“We have learned that new ideas emerge when we bring together experts with different experiences and perspectives,” said Lynn Broaddus, director of the environment program at The Johnson Foundation. “Getting out ahead of our water security challenges and achieving long-term sustainability of the nation’s water resources in the face of climate change, energy constraints, diminishing groundwater supplies, financial challenges, and other resource constraints is going to take a comprehensive and cross-sector approach to the issue.”
