What state has the best water in the US?

As an avid traveler and health-conscious individual, I'm often curious about the quality of water in different states across the United States. So, I have to ask, which state boasts the best water in the entire country? Is it a state known for its pristine lakes and rivers, or perhaps one with advanced water treatment facilities? I'm eager to learn more about the factors that contribute to the superior quality of its water, whether it's natural geography, environmental regulations, or a combination of both. Additionally, I'm also interested in understanding how residents of this state perceive the taste and clarity of their tap water, as well as any notable initiatives or achievements in water conservation and sustainability.
