Estimates of Nitrogen Loads Entering Long Island Sound from Ground Water and Streams on Long Island, New York, 1985-96.

摘要

This report presents (1) geographic, seasonal, and long-term trends in nitrogen concentration in the four major north-shore streams that discharge to Long Island Sound, (2) annual mean nitrogen concentrations in these streams, and the annual mean nitrogen loads discharged from these streams to the Long Island Sound, during 1985-96, (3) nitrogen loads discharged from shallow and deep aquifers in Nassau and Suffolk Counties to the Sound, and (4) loads to discharged from the shallow aquifer in three separate land-use areas, for comparison of the effects of land use on nitrogen loads entering the Sound.
