Environmental Quality: Restoring Bronx River. By: Swapan Bhuiyan

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

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

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

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

Results Yearly AveragepH Dissolve OxygenSalinityAir Temperature Water Temperature ppm16 ppt 23.9  C19.6  C ppm18 ppt 20.2  C17.5  C ppm15 ppt 19  C14.7  C 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 This is due to our desire to show comparison among the data.

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