  1. Environmental Quality:Restoring Bronx River. By: Swapan Bhuiyan

  2. Introduction The Bronx River • Twisty stream • Floodplains, marshland, ravines, beaver and salt-water marshes. • During 1820’s to 1830’s • Late 1800’s Effects of Water Pollution • Unbalanced river, disrupt lake ecosystem • Poisonous food animals (bio-accumulation of toxins) • Poisonous drinking water • Acid rain  Deforestation

  3. Introduction Cont’d The Bronx River • Railroad (1840’s) • Industrialization • “Open Sewer.” Three sites (Estuary Section) • The Soundview Park • Concrete Plant • Starlight Park

  4. Goals • Study quality of water • Analyze the newly obtained data • Compare it with the previous data • Make statistical justifications • Draw valid conclusions Objectives • Salinity • pH level • Dissolved Oxygen level • Water temperature • Air temperature • Nitrate • Turbidity • Saturation of Oxygen in water

  5. Hypothesis • The water quality has improved Procedure • Air and Water Temperature • Turbidity • Salinity • Dissolve Oxygen • Nitrates • pH • Saturation of Oxygen

  6. Results • The pH difference • The DO difference and temperature connection • Salinity • The data for several tests are not shown for several test we did not conduct those experiments for the year 2003. This is due to our desire to show comparison among the data.

  7. Discussion • Bronx River is worse from year 2003. No real changes has occurred in the river. • The results indicate that the water of the river remains polluted.

  8. Cleaning The River • Oysters • Clean the water • How • Getting the Oysters • Oyster Habitat • Lantern Nets • What we are doing with this study. • The result we expect • The license
