In this article, we will discuss the 25 US cities with cleanest air and water. If you want to skip our discussion on the overall environmental conditions in the US, you can go directly to the 5 US Cities with Cleanest Air and Water.
According to IQAir US, the air quality in the United States was rated as "good" compared to other countries in 2022. The US Air Quality Index (AQI) was recorded at 37, positioning it 99th out of 131 countries in the global ranking. The air quality challenges are not uniform within the United States itself. Some US cities, like Bellingham, enjoy air quality on par with the cities with the best air quality in the world. On the other hand, there are some US cities with the worst air quality, often due to specific regional challenges. For instance, the release of soot from wildfires in California often results in extremely hazardous air quality conditions in the area. Tragically, in 2020, these wildfires led to approximately 1,200 deaths and caused 4,800 emergency room visits due to breathing difficulties. Due to the severity of this issue, efforts are being made to control the harmful impact of wildfires, with an allocation of $1 billion for fire management as of 2021. Meanwhile, reports have brought to light concerns regarding Shell plc (NYSE:SHEL) industrial facility located in Pennsylvania, which holds the distinction of being permitted as the second-largest emitter of volatile organic compounds (VOCs). In September 2022, even before regular operations began, the plant emitted a significant 510.89 tons of VOCs, alarmingly close to its annual limit of 516.2 tons. Furthermore, in subsequent months, the plant consistently exceeded its 12-month permit limits, indicating a pattern of emissions surpassing legal allowances. While economic growth in sectors such as fossil fuels and agriculture can have positive effects on the economy, this development often comes at the cost of increased air pollution.

As per the Centers for Disease Control and Prevention (CDC), around 7.2 million Americans get sick annually due to water-borne diseases. Moreover, over 3.5 million Americans experience health issues such as skin rashes, respiratory infections, and hepatitis due to exposure to contaminated coastal waters every year. A study by the US Geological Survey revealed that nearly half of the United States tap water may contain traces of chemicals, commonly referred to as “forever chemicals.” The actual concentration level may even be higher as the study only looked at 32 per- and polyfluorinated alkyl substances (PFAS), while the National Institutes of Health has identified over 12,000 PFAS. These chemicals have been linked with diseases like liver damage, cancer, and high cholesterol. The increase in water-borne diseases has also led multiple healthcare companies like Pfizer Inc. (NYSE:PFE), Merck & Co., Inc. (NYSE:MRK), and AbbVie Inc. (NYSE:ABBV) to invest more in their drug pipelines.
Many companies are actively taking steps to eliminate or reduce their contributions to air and water pollution. This reflects a growing awareness of the importance of environmental sustainability and responsible business practices. For instance, Ikea, one of the leading home furnishings retailers, has undertaken many initiatives to combat air pollution over the years. Notably, as a co-founder of the Alliance for Clean Air, Ikea plays an active role in initiatives aimed at enhancing air quality. The company has also launched the "Better Air Now" program, which aims to utilize rice straw residue for both packaging materials and bioenergy production. Similarly, in 2022, Adidas partnered with Parley to combat water pollution. They produced 15 million pairs of shoes from recycled coastal plastic waste and aimed to increase production to 17 million pairs in 2021.

Our Methodology
To shortlist the 25 US cities with cleanest air and water, we referred to multiple reputable sources, such as the United States Environmental Protection Agency (EPA), the American Lung Association, and the Consumer Confidence Reports (CCR) database. The primary metric for shortlisting these cities was the American Lung Association’s year-round particle pollution data. The cities have been ranked in descending order of their pollution levels as of 2021. The water quality scores have been obtained from the EPA's Safe Drinking Water Information System and CCR database. For cities with no water quality score, we referred to individual city reports to get information regarding compliance with health standards. With this context in mind, let's take a look at the air and water quality by city in the USA.
