Problem – Currently, swim advisories or closings are issued by beach managers based on standards for concentrations of bacterial indicators such as Escherichia coli (E. coli). Standard culture methods for these bacteria take at least 18-24 hours before results are available. At most Great Lakes beaches, the beach is posted with an advisory or closing or is determined to be acceptable for swimming on the basis of the previous day’s E. coli concentration. Sanitary conditions may change overnight and even throughout the day (Boehm and others, 2002) making decisions made from previous days information incorrect. Because of this time-lag issue, water-resource managers are seeking solutions that provide near real-time...

From April through September of 2018, water-quality data were collected at 35 locations from select tributaries, embayments, and nearshore lake locations along New York's portion of Lake Ontario in support of the 2018 Cooperative Science and Monitoring Initiative, the Great Lakes Restoration Initiative, and the Lakewide Action Management Plan. These data include environmental, replicate, and blank samples of nutrients, suspended solids, sodium, and chloride, as well as field measurements of physical parameters (temperature, specific conductance, dissolved oxygen, pH, turbidity, phycocyanin relative fluorescence, chlorophyll relative fluorescence, photosynthetically active radiation, and phycocyanin:cholorphyll...

In 1979, the U.S. Geological Survey (USGS) entered into a cooperative agreement with Monroe County (MC), which, over the span of more than three decades, has resulted in more than 30 reports that have summarized flow and water-quality data at sites in Monroe County and have presented the results of investigations of particular water-related issues that existed in the County. The collaborative relationship between Monroe County and the USGS entails: - USGS training and oversight of MC personnel to conduct site visits and measure streamflow and collect water samples at monitoring sites; - analyses of water samples by MC in a certified environmental laboratory that routinely participates in a USGS quality-control program...

Background The proposed study will examine any existing data from the monitoring wells, weather station, and flow through the storm sewer system (supplied by Buffalo Sewer Authority) to determine the dynamics of the system during storm events. Further analysis using all available information is needed to fully understand the relationship of events to the implementation of Green Infrastructure stormwater-control measure effectiveness. Questions to be addressed include: How do pipe flows and groundwater levels respond to storms? Can the data be used to quantify water-budget components at the site? To what extent can the effect of the Green Infrastructure in reducing stormwater volumes and peaks be quantified? Based...

The Great Lakes Restoration initiative (GLRI) template #77 (Beach Recreation Water Quality) in cooperation with 23 local and state agencies expanded the use of predictive modeling at 45 beaches throughout the Great Lakes (fig 1). Local agencies measure fecal-indicator bacteria such as Escherichia coli (E. coli.) along with easily obtained environmental variables used as surrogates to estimate concentrations of fecal-indicator bacteria through a predictive modeling approach. The predictive modeling is being developed by the use of linear regression and/or partial least-squares techniques. The models use software developed by the U.S. Environmental Protection Agency known as “Virtual Beach”. Each beach model is based...

Lake Ontario is the easternmost Great Lake and has a direct drainage area of 24,720 square miles (mi2)(excluding the Niagara River and upper Great Lakes watershed), and is bounded by the Canadian Province of Ontario to the north and west and New York State to the south and east. Lake Ontario receives its primary inflow from the watersheds of the upper Great Lakes through the Niagara River near Youngstown, New York, a drainage area of 263,700 mi2. The U.S. Environmental Protection Agency (EPA) is administering a program called the Great Lakes Restoration Initiative (GLRI), which was launched in 2010 to accelerate efforts to protect and restore the health of all the Great Lakes USEPA GLRI Action Plan I & II, (Great...
