Long‐time records of ground‐water levels on Long Island, New York

As early at 1851 the need for information as to the position of the water‐table was recognized by workers on Long Island. In that year water‐level measurements were made in about 32 domestic wells in the southern part of Kings and Queens counties, New York (W. J. McAlpine, Report made to the water committee of the common council of the City of Brooklyn on supplying the City with water, p. 113, Brooklyn, I. Van Anden, 1852). Although specific water‐level data are given in this report, it has not been possible to determine the exact locations of the old wells that were measured, or the months during which measurements were made.
