Acidification and Recovery and Development of Critical Loads of Acidity for Stream Ecosystems of the Adirondack Region of New York State

BACKGROUND The Adirondack region of New York has a history of relatively high atmospheric sulfur (S) and nitrogen (N) deposition (Greaver et al. 2012). Adirondack ecosystems have been impacted by these inputs, including soil and surface water acidification, and impaired health and diversity of forest vegetation and aquatic biota. Air quality management, through the Clean Air Act, the U.S. Envir

Simulation and Analysis of the Effects of Land-Use Changes and Stormflow Detention Basins on Flooding and Nonpoint-Source Pollution, in Irondequoit Creek Basin, Monroe and Ontario Counties, New York

Problem - Urbanization of the 150-square-mile Irondequoit Creek basin in Monroe and Ontario Counties, N.Y., continues to spread southward and eastward from the City of Rochester. Conversion of forested land to other uses over the past 40 years has increased to the extent that more than 50 percent of the basin is now developed. This expansion has increased flooding and impaired stream-water qual

Simulation of Flow and Water Quality by a Precipitation-Runoff Model of the Onondaga Lake Watershed, Onondaga County, New York

Problem - During 2003-07, a precipitation-runoff watershed model with water-quality components was developed to assess pollutant sources and loadings to Onondaga Lake, and to assist water-resources managers in making decisions regarding the selection and location of mitigative measures to maximize load reduction for a given effort. In the absence of chemical loading rates that were specific to
