New Initiative to Safeguard Long Island's Aquifers from Overpumping and Saltwater Intrusion
The 2050 LI Groundwater Rebalance project aims to mitigate Long Island's groundwater depletion and saltwater intrusion over five years. This initiative is critical as excessive water extraction threatens aquifer integrity, with potential for increased salinity in drinking water sources.

A five-year initiative, the 2050 LI Groundwater Rebalance, has been launched to address overpumping and saltwater intrusion in Long Island's aquifer system. This project involves collaboration among water suppliers, groundwater management experts, and local activists following findings from a U.S.
Geological Survey study indicating significant stress on the aquifer. Average water consumption on Long Island is 140 gallons per person daily, significantly above the national average, with summer demands nearly tripling.
Proposed solutions include replacing impermeable surfaces with permeable materials and encouraging native grasses for landscaping. Additionally, large infrastructure projects for stormwater capture are advocated to enhance aquifer recharge.
The Long Island Commission for Aquifer Protection promotes unified messaging across the island but requires increased funding to be effective. Collaboration between water suppliers and environmentalists is vital to prevent well contamination.
