A sweet presentation about water pollution

1. Turbidity of Water Research Question How does the turbidity of water in the Wenyu River vary at different intervals from the Jingshun Lu Subway Bridge construction site?

5. Variables & Procedure Independent Variable Distance downstream river from construction site Dependant Variables The turbidity (transmittance) Controlled Variables South bank Colorimeter Wavelength Settlement Distance from the bank Day

11. Raw & Processed Data

12. Conclusion Sedimentary deposits most significant at Construction site Proportional Relationship distance from construction site (downstream) α turbidity of river water

13. Evaluation GPS precision questionable River depth varies Speed of water flow inconsistency More trials needed
