Backed by leading research
New discoveries of fresh, sustainable groundwater are happening regularly – and they point to vast reserves deeper than most wells ever reach.
22.6 million km³ of groundwater
The U.S. National Groundwater Association estimates enough groundwater in the upper 2 km of Earth's crust to supply the planet for over 6,000 years.
The Maverick Basin Aquifer
A newly named Texas aquifer – 3,000+ sq miles, ~1,000 ft thick – producing water that already meets federal drinking-water standards.
A giant offshore freshwater pool
Freshwater off New England spanning Delaware to Massachusetts – twice the volume of Lake Ontario (Scientific Reports).
Offshore submarine freshwater
Twice as much freshwater is stored offshore of Hawai‘i Island than previously thought (Science Advances).
Water in Earth's lower mantle
A peer-reviewed paper found Earth's lower mantle may store about five times more H₂O than the oceans.
An ocean's worth of water
