For more than 50 years the highly productive and readily replenishable water-bearing sands and gravels on Long Island -- capable of yielding an average of at least 1,000 million gallons a day -- and also some surface streams and ponds have been utilized on a large scale of public water supply and industrial, agricultural and domestic uses. During the drought months of 1949, when many surface and groundwater supplied were being depleted at an alarming rate in many localities in the Northeast, the abundant water resources of Long Island provided sufficient water for public water supply for a large number of private companies and municipalities, as well as for large emergency drafts by the City of New York. In addition they kept industrial concerns from curtailing production, saved millions of dollars of potato, cauliflower, and other Long Island crops, and even furnished, during the summer heat, comfort cooling and theatergoers.
