Drinking Water Systems

There are two types of drinking water systems in the United States. They are:

• Public water systems that are subject to United States Environmental Protection Agency (EPA) regulations.

• Individual water systems that are not subject to EPA regulations.

According to the EPA, approximately 286 million Americans receive their tap water from a community water system. These public water systems are monitored and regulated as set by the EPA.

An estimated 15% of Americans, or about 45 million people, get their water from private ground water wells that are not subject to EPA regulations. Private ground water wells can provide safe, clean water. However, well water can also become contaminated, leading to illness. It is the responsibility of well owners to maintain and treat their well.
