Generation Next: CLEAN-India Water Testing
Ms. Shalini distinguished between parameters for drinking-water and that for surface bodies of water. For example, parameters such as Dissolved Oxygen, Benthic Diversity, and Turbidity are more important when testing for the water quality of lakes and rivers than drinking-water, as these factors are critical to the survival of aquatic life.
Although not directly applicable, students also conducted the tests for surface water bodies (i.e. turbidity) using their drinking-water samples. Overall, students enjoyed conducting the experiments—especially those involving the observation of color changes and titrations (most students were not familiar with this lab procedure).
