Hypothesis- If the water is filtered then boiled then there will be no bacteria because the heat from the boiling water will kill all the bacteria. Research shows that filtering takes out most large amount of bacteria while the boiling kills all the bacteria left and the charcoal takes out all large material like rocks or sand.
