  2. 2. 2 Overview of Jamaica Bay  Jamaica Bay is designated for primary contact and it’s tributaries are designated for secondary contact  Water quality in Jamaica Bay is better than its been in 100 years and supports a wide variety of wildlife but there are still impairments:  Waters tend to be eutrophic  Seasonal low DO levels  These water quality impairments are linked to high nutrient loadings in conjunction with man- made physical alterations  DEP is upgrading all for of it’s WWTP that discharge into Jamaica Bay for Step Feed BNR  Loss of the marsh islands is another critical issue within Jamaica Bay  DEP has partnered with ACOE to restore many of these marsh islands ($13M funded)
  3. 3. 3 Historical Water Quality
  4. 4. Additional Water Quality Studies  In 1995/96 DEP conducted comprehensive water quality and ecological studies to calibrate JEM  Subsequent comprehensive water quality, ecological, and finfish studies were conducted in 2005/2006  Ongoing Jamaica Bay Science & Resiliency Institute will be refining JEM  DEP to conduct a comprehensive Post Construction Monitoring Plan from 2016 thru 2019 4 Water QualityWater Quality MarshlandMarshland UlvaUlva PhytoplanktonPhytoplankton
