Offshore Atlantic freshwater reservoir confirmed, NYC could be supplied for centuries

A drilling expedition (IODP-NSF Expedition 501) off Nantucket and Martha’s Vineyard confirmed a massive freshwater reservoir buried beneath the Atlantic seafloor along the U.S. Northeast, extending from New Jersey to Maine. Recovered low-salinity water and a robust impermeable cap suggest the reservoir formed about 20,000 years ago during the last glacial period, and it could theoretically supply New York City with drinking water for around 800 years. While offshore extraction would require new infrastructure and carries environmental uncertainties, the finding implies potential, long-term backup water resources in other coastal regions as well.

Massive freshwater layer found beneath Great Salt Lake could reshape Utah's water future

Scientists using airborne electromagnetic surveys found a deep layer of fresh water beneath the eastern margin of Utah's Great Salt Lake, ranging from about 100 meters to 2.5 miles deep. The water likely originates from surrounding mountains and is trapped by underlying rock, suggesting a potentially vast reservoir that could help damp toxic dust from exposed lake beds and provide irrigation water, though expansion of the survey is needed to determine full extent.

Ancient Offshore Aquifer Near Northeast Coast Could Back NYC Water Supply for Centuries

Researchers confirmed a large, low-salinity offshore freshwater reservoir beneath the U.S. Atlantic shelf, formed by glacial meltwater about 20,000 years ago. While not yet exploitable and facing legal, environmental, and engineering hurdles, the discovery highlights offshore groundwater as a potential long-term resource for coastal cities like New York City, should future technologies and policies enable sustainable use.

Giant undersea freshwater reservoir off the Northeast coast could fuel NYC for centuries

Scientists drilling off the Massachusetts coast confirm a massive freshwater reservoir buried beneath the seafloor, likely formed during the last ice age about 20,000 years ago. Early data suggest the pool may extend farther than first thought, potentially providing a city the size of New York City with hundreds of years’ worth of water (around 800 years), with more definitive results expected in about a month.
