Water paper
Why is it that the United States, the most industrialized nation in the world, is able to tackle everything from curing deadly diseases to genetic engineering but not able to resolve such a simple issue as the safety of our drinking water, which threatens the very health of million of Americans today. Over the last few years, Americans have spent an average of $2.1 billion dollars on bottled water and astounding $450 million dollars on home treatment systems.

In conclusion, the laboratory results confirm the hypothesis that water sample C is positive for presence of Coliform. While testing water samples A, B and C, both A and B are eliminated as a positive presumption because after having been incubated for 48 hours, they showed no sign of acid and gas together. Therefore, it follows that they are presumed negative for coliforms and safe to drink. Water sample C tested positive for Coliform making it unsafe water to drink.
