Summary

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, proximity of point [...]

typeShort Project Description
valueThe presence of pathogens in Long Island marine embayments and the hazards they pose to marine resources and human health is of increasing concern. The USGS will identify the sources of pathogen contamination and relative loads to Long Island’s marine embayments using a multi-tiered approach to microbial-source tracking in the embayments identified by the DEC as pathogen impaired..
projectProducts
productDescriptionAll data will be disseminated via the NWISWeb site (National Water Information System: Web Interface) at http://waterdata.usgs.gov and on a USGS ScienceBase project page (https://www.sciencebase.gov). Data will be presented and incorporated into a USGS interpretive report with a technically acceptable draft planned for September, 2019. A companion GIS product will also be published through USGS ScienceBase that will identify sample locations, areas of observed bird populations, boat docking/mooring, and stormwater outfalls; and help visualize areas of pathogen host and estimation of pathogen loads.
