About Water Quality

Millions of American households suffer some kind of correctable water problem. Hard water alone is found in 85% of all American homes, according to the U.S. Geological Survey. Other common water problems include excess iron, manganese, hydrogen sulfide gas (“rotten egg” smell), acidity, various levels and types of bacteria, and cloudy water.

Each of these problems can bring its own unpleasant effects into your home. Rusting and corroded pipes, clothing stains, bad tasting water, health issues, and higher water heating bills are just a few of the possible results of problem water, which can take money out of your pocket and affect the quality of your life.

This table lists many of the contaminants found in water, along with the solutions available to remove these problems.
