Water quality can no longer be taken for granted. There are many variables that can come into play: the possibility of contamination, our aging water distribution system, unknown well-water quality and the type of plumbing in your home. And unbeknownst to many, municipalities can supply you with hard water. They are also supposed to provide you with water that meets federal standards, but are those standards your standards?
With public water, the government works very hard to ensure your water is safe to drink. Unfortunately, some contaminants may be difficult to detect or realistically treat on a large scale, or may enter the water system through gaps in the infrastructure, such as aging pipes.
Private water sources bring their own challenges and deserve extra attention and precautions, including regular testing for safety. Water that comes in contact with annoying or harmful contaminants, both natural and man-made, can carry them along into your home.
