Recently, it came to our attention that 64 million Americans have unsafe drinking water. Filtering tap water these days is not a luxury, but a necessity. There are too many contaminants in our groundwater from factories and underground pollution.
Regardless of how good your tap or well water may seem, it has some contaminants. Some of these come from environmental pollutants, while others come from natural surroundings. Rivers and lakes are generally good forms of water, yet they still get contaminated by pollutants, acid rain, and storms.
