2006-present, Principal Investigator, Water Resources of Monroe County, New York, Streamflow, constituent loads and trends in water quality, in cooperation with Monroe County Department of Health. Using techniques for Exploration and Graphics for RivEr Trends or (EGRET), an R-package for the analysis of long-term changes in water quality and streamflow, including the water-quality method weighted regressions on time, discharge, and season (WRTDS). Applying new methods designed to study long-term streamflow change associated to land use and water use change, estimations in concentrations, flow-normalization, and estimated flux by integrating flux over the frequency distributions of flow. Using short term USGS LOADEST AMLE seasonal regressions to determine direct loading of watersheds and ESTREND analysis for watersheds, 5, 10, 20 and 35 year trends in Monroe County.
2010-present, Principal Investigator, Lake Ontario Tributary study New York. Real-time monitoring, water-quality of phosphorus, and orthophosphate (SRP), total mercury, and dissolved organic carbon loading into Lake Ontario, in cooperation with the U.S. Environmental Protection Agency, Lakewide Management Plan (LaMPs). Using short term USGS LOADEST AMLE seasonal regressions to determine direct loading of watersheds and ESTREND analysis for watershed for 5yrs into Lake Ontario. Environmental pollution assessment of total mercury and dissolved organic carbon sources and regression relationships to methyl mercury for tributaries to Lake Ontario. Evaluating the Connecting Channels of the Niagara River Upstream/Downstream and St. Lawrence for critical pollutants and emerging toxins, major ions, inorganics, organics, microplastics, nutrients, dioxins loading into Lake Ontario from Lake Erie Inputs, in cooperation with the U.S. Environmental Protection Agency, Lakewide Management Plan (LaMPs). Investigating and authoring a report for temporal variations and concentrations of wastewater, antibiotic compounds, polycyclic aromatic hydrocarbons, 22 elements, inorganics, polychlorinated biphenyls, dioxins, furans, and microplastics on the upper and lower Niagara River.
2010-present, Principal Investigator, Great Lakes, New York-Ohio NowCast. Real-time predictions of fecal contamination, multi-variant statistical analysis and Nowcast development, in cooperation with New York State Health Department, coastal area County Health Departments and the U.S. Environmental Protection Agency, Great Lakes Restoration Initiative (GLRI). Quantifies Escherichia coli and enterococci in beach waters and dominant source materials, correlates these with ambient conditions and models the predictions base on multi-variant regressions. Organizes 5-departments of health real-time model validations and runs the New York beach advisory network to Nowcast data from third-party sources; such as National Weather Service, National Oceanic and Atmospheric Administration and the Environmental data Discovery and Transformation data portal.
2012-present, Co-Investigator, Estimating Loading Above and Below Agricultural Best Management Practices (BMPs) and Combined Animal Feeding Operations (CAFOs) in the Genesee River Watershed loading into Lake Ontario. In cooperation with the U.S. Environmental Protection Agency, Lakewide Management Plan (LaMPs). Using short term USGS LOADEST AMLE seasonal regressions to determine direct loading of the Genesee River watershed and evaluating spatial best management practices for manure applications within 12-digit HUCs. Directs and coordinates with NY Department of Environment Services for sampling throughout the basin. Authoring a report on Estimating loading above and below Agricultural Best Management Practices in the Genesee River Watershed.
