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 q...

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...

Simulation of Ground-Water Flow and Chemistry to Evaluate Water-Management Alternatives in Kings and Queens Counties, New York

Water-management alternatives being considered for New York City involve aquifer storage and recovery, or ASR. An ASR system may store surplus water in an aquifer, then later recover this water in times of short supply. The success of an ASR system depends on the quantity and quality of water that can be withdrawn during recovery phases, which are influenced by hydrogeologic, microbiologica...

Anticoagulant rodenticide toxicity to non-target wildlife under controlled exposure conditions

Using these data, an adverse outcome pathway identifying molecular initiating and...
