'MURICA — What is raw water you ask? It's unfiltered, untreated, unsterilized water collected from natural springs. <br /> <br />Raw water fans are worried about contaminants such as chemicals and lead in municipal water and additives such as fluoride. <br /> <br />It's also ridiculously expensive. In SF, it can cost $61 dollars for a 2.5 gallon jug of raw water that could also give you raw cholera. Yay! <br /> <br />Besides cholera, the clearest stream water can still be filled with animal doo doo, Hepatitis A and E. Coli.
