  1. Long Island Coastal Resiliency And Clean Water Infrastructure Stakeholder Meeting Larry Swanson SoMAS Stony Brook University May 28, 2014

  2. Water Quality or Carrying Capacity Loading (legacy N + new N – environmental denitrification) Residence Time Carrying Capacity

  3. Carrying Capacity – the maximum number of individuals that an area of land or water can support without detrimental effects.

  4. Annual Mass Loadings: Bay Park STP

  5. Annual daily averaged discharge at Bay Park and Cedar Creek WPCP 1952-2010.

  6. Residence Time- time required to advect water parcels from one water body to another.

  7. Residence Times for • Groundwater  relatively short • Coastal Waters  generally long

  8. Residence Time for Selected Water Bodies

  9. Residence times of particles in West and Middle Bays. Color bar is time in hours.

  10. Comparison between Ulva growth and surface nitrate concentrations.

  11. Cross Section of DO Concentrations Along Wills Creek and Across Forge River

  12. Source: CT DEP

  13. Summertime Residual Currents in Central Long Island SoundLevel 6 10 cm/s

  14. Develop and Embrace New Technologies and Systems

  15. New sewage treatment capacity and technology can significantly reduce impacts of nitrogen pollution - not eliminate it

  16. Controlling Mass Loadings (not just concentrations) and Planning for Residence Times are Essential

  17. Long Island’s carrying capacity dictates that there are “limits to growth”
