Ground-Water Resources of Kings and Queens Counties, Long Island, New York

摘要

This report describes the structure and operation of the western part on the Long211u001eIsland ground-water system. It describes the hydrologic effects associated with 211u001ehuman development in this highly urbanized environment from 1900 to the early 211u001e1980's. The groundwater quantity and quality of recent (early 1980's) conditions 211u001eis characterized and a discussion of groundwater resource concerns is offered. 211u001eSpecifically, it: (1) delinates the hydrogeologic framework of the western part 211u001eof the Long Island ground-water system and defines its water-bearing 211u001echaracteristics, (2) describes ground-water flow patterns, the ground-water-211u001esystem budget, and ground-water quality under predevelopment conditions, (3) 211u001esummarizes the development of the ground-water system and the effects of 211u001eurbanization by presenting historical pumpage data and other urbanizing factors, 211u001eand presenting the subsequent response of the ground-water system, and (4) 211u001epresents the recent patterns and distribution of ground-water flow, and 211u001econcentrations of selected chemical constituents that indicate the extent of 211u001ehuman-derived contamination and saltwater intrusion throughout the ground-water 211u001esystem.
