City water may be treated, but some municipal water supplies still require in-home water treatment.
Although municipal water is treated before it reaches your home, most city water is still hard and may contain some level of contaminants. Municipal water treatment plants are required to provide water that meets federal regulations, but it’s becoming more challenging for them to meet these standards. More importantly, are federal standards the same as your standards? No matter how pristine the water seems when it leaves the treatment plant, it still must travel through an aging distribution system and and can pick up impurities along the way.
There are a number of treatment methods to improve the quality of city water. The appropriate method is determined by the water’s quality and how it will be used in the home.
