Best Tap Water in the U.S.

In all corners of America, from Alaska's glacial rivers to Florida's tropical springs, the quality of tap water is a testament to the natural resources, infrastructure, and regulatory fortitude of each state. With over 50,000 community water systems in the U.S, the quality of tap water can drastically vary, making it an intricate part of our everyday lives and health. According to the most recent water quality violation data, there is a wide range in the commitment and success by states in maintaining compliance with federal water standards.

Our analysis relies on the water quality violations metric, which catalogues the instances when tap water quality fails to meet federal guidelines in a state. Fewer violations commonly indicate a more robust drinking water sector and cleaner tap water. Still, it's necessary to remember that these figures are statewide totals and might not reflect the specific conditions in individual cities or communities.

Key findings from our investigation into the data include: 

• Hawaii shines as the U.S state with the best tap water, recording a mere two water quality violations. This is a remarkable achievement given the standard of federal water quality regulations.
• The two subsequent top-performers are Nebraska and Delaware, with 121 and 131 violations respectively.
• An alarming trend emerges as we analyze states at the other end of the spectrum. Texas (23,628 violations), Pennsylvania (21,527 violations) and West Virginia (8,490 violations), are struggling significantly with maintaining clean tap water.
• Overall, a strong geographical trend doesn't leap out from the data, with top performers spread across the country, from the islands of Hawaii to the heartlands of Nebraska.
