In cooperation with the New York City Department of Environmental Protection (NYC DEP), the U.S. Geological Survey (USGS) collected water and bed sediment samples along Alley Creek (Queens, New York) to help determine likely sources of fecal bacteria to the creek and Little Neck Bay. Potential terrestrial sources include stormwater, sewage via combined sewer overflow (CSO) and compromised infrastructure, bed-sediment resuspension, and groundwater discharge. Host sources that were targeted using microbial source tracking (MST) techniques included human, canine, waterfowl, and general Bacteroides. Routine water samples were collected and analyzed for the fecal indicator bacteria enterococci and fecal coliform, along...

Problem The presence of pathogens in Long Island marine embayments and the hazards they pose to marine resources and human health is of increasing concern. Many waterbodies on the New York State Section 303(d) List of Impaired Waters have pathogens listed as the primary pollutant that are suspected to originate from urban/storm runoff. There is neither a clear understanding of the relative magnitude and geographic origin of sources of loadings of pathogens (from urban/storm runoff, submarine groundwater discharge, etc) on Long Island, nor clear understanding about the host organisms from which they originate (such as human, mammals, or birds). Pathogen loads to specific embayments are affected by watershed land-use,...

This data set contains continuous water-surface elevation and water-quality (temperature, specific conductance, salinity, and turbidity) data recorded at 6- and 15-minute intervals, respectively, from two sites in the Bronx on the Harlem River -- Roberto Clemente State Park and Mill Pond Park. Water elevation was monitored every second to detect changes indicative of boat wakes expected to resuspend bed sediment from nearby alcoves. Boat wake detection triggered the collection of 1-second interval water elevation and 1-minute interval turbidity data. In addition to continuous data, grab samples for fecal indicator bacteria (Enterococci) and total suspended solids were collected weekly from - March to September,...

PROBLEM Alley Creek, a tributary to Little Neck Bay (Queens County, New York; figure 1) has been designated as impaired by the New York State Department of Environmental Conservation (NYS DEC) for primary and secondary contact and included on the 303(d) Impaired Waterways for pathogens related to combined sewer overflow contributions. The New York City Department of Environmental Protection (NYC DEP) and New York City Parks & Recreation have developed a long-term control plan (2014) and a watershed management plan (2015), respectively, to improve water quality and ecosystem health. Point and non-point sources of pathogens are implicated, including stormwater and combined-sewer outfalls, groundwater seepage, and...
