Microbial Aerosols and Water to Air Transfer:
.Sewage released gets restricted to the surface in a density-stratified layer.
.Sewage and antibiotic resistant bacteria are present in HRE surface waters.
.Any surface disruption of the contaminated waters may cause the release of raw sewage in the air.

Questions:
Do we meet EPA standards in the HRE region in regards to levels of Enterococcus?
Are there areas at more risk than others close to CSO?
Do the Patterns show any form of environmental discrimination?
Any Year long similarities?

Methods: Weekly Samples were collected from Previous Personal research and the
River Keeper of levels of Enterococcus in the Hudson River Estuary.
Data from 2008 to 2012 were averaged from the exact same months and time of sampling and Coordinates verified using Google Earth.
Excel spreadsheet was created with values for every season and X and Y Long and Lat.
Maps of NYC area were layered to give desired look added to GIS and attributes tables matched and joined
Thematic maps created for each season with EPA standards and then put together for analysis
Income attribute table from Census joined to maps to show low to high income regions and Hazard ranking was established for each season.
Ranks where placed over income maps to compare values
And a year long danger map was clipped and created

Results:
Enterococcus EPA Acceptable levels are not met.
Some values are extremely high.
Low income level location suffers most bacteria levels.
Spring and Summer seasons are worse than Fall due to precipitations.
