The Environmental Protection Agency (EPA) has recently released information stating that, no matter where we live in the United States, there is likely to be some toxic substance in our groundwater. Indeed, the agency estimates that one in
five Americans, supplied by one-quarter of the nation’s drinking water systems, consume tap water that violates EPA safety standards under the Clean Water Act.
The most obvious solution to water pollution is a point-of-use water
purification device. The tap is the end of the road for water consumed by our families, so this is the logical, and most efficient, place to focus water treatment.
Note: RO systems have two major drawbacks.
