Summary

Problem The discharge of freshwater and associated loading of nutrients and other dissolved constituents from the Long Island aquifer system to surrounding estuaries and their tributaries are increasingly recognized as critical factors in the health of these ecosystems. However, further work is needed to scientifically characterize these factors and present them to the public in an appropriate manner. Many organizations have undertaken assessments of this discharge and loading for discrete groundwater source areas and (or) receiving surface waters, applying a variety of techniques and assumptions. In part, this is because there is no delineation of recharge areas to the island’s groundwater-fed streams and estuaries that is comprehensive, [...]

typeShort Project Description
valueA comprehensive and fully documented set of publicly accessible delineations of the recharge areas and resulting traveltimes for groundwater discharge to Long Island streams and estuarine embayments is essential for developing informed strategies to address pollutant loading to these systems, to provide the basis for further scientific study, and to engage the public. The primary objectives of the proposed investigation are to (1) delineate present-condition ground-water recharge areas and traveltimes to Long Island streams and estuarine embayments, and (2) produce geospatial layers and metadata that describe these delineations for public dissemination via the Internet.
