Top 10 States With the Worst Public Water Ratings in the United States

When the water crisis of Flint, Mich., hit national headlines in 2015, U.S. water quality became a topic of national conversation. But as recent research shows, Michigan isn’t the only state dealing with dangerous water.

The study revealed that from 1982 to 2015, between nine and 45 million Americans received water from a source that violated the Safe Drinking Water Act. While unsafe water flows across the nation, the most affected areas were low-income and rural. In part, this is because the latest water treatment technology is expensive — many small water systems find it difficult to keep their water treatment techniques to federal standards.

We’ve gathered the top 10 states with the worst public water ratings across the country, ranked by the total number of people served with unsafe and hazardous water. If your state is on the list, don’t worry — at the end of the article, we go into methods that you can use to test and improve the quality of your water.

States With the Worst Drinking Water

These states may have beautiful scenery, productive markets, and diverse cultures, but they share one thing in common — hazardous water quality.

10. Arizona

Arizona sprawls across the deserts and mountains of the western United States. Throughout the region, water is scarce and growing scarcer — but getting enough water isn’t the state’s only problem.

Arizona tap water is also one of the most dangerous in the nation. According to recent reports, Phoenix tap water has the highest average levels of chromium-6, a known carcinogen, in the United States. Other toxins linked to cancer and developmental issues, such as PFCs, taint the water systems.

According to the Natural Resources Defense Council (NRDC), in 2015, Arizona had 2,362 violations of the Safe Drinking Water Act. In total, 2.46 million residents were served with contaminated water — 36 percent of the state’s population.

9. California

The Golden State is home to warm vineyards and the second-largest city in the country. But it also suffers from pollution.

Heavy smog affects the state’s air quality — in 2018, Californian towns claimed eight out of 10 spots on the American Lung Association’s annual 10 most-polluted cities list. But the pollution isn’t restricted to the air. Many of California’s rural, farming communities are drinking from arsenic and uranium-contaminated water systems. Combined with high nitrate levels from agricultural use, the pollution is high enough to potentially cause cancer and developmental issues in children.

In 2015, 2.57 million Californian residents were served by water systems that violated the Safe Drinking Water Act, putting 832 communities at risk. Unlike its air pollution, which is concentrated around its large urban centers, California’s poor drinking water affects mostly its low-income and rural communities. While the state has started to take action, it may take decades to remediate the drinking water challenges.

8. Ohio

One of America’s industrial centers, Ohio is also one of its most polluted states.

In 2016, the town of Sebring discovered they had a Flint-like problem — unsafe levels of lead were found in the water system, leading to a brief shutdown of schools and businesses. Since then, conditions have somewhat improved throughout the state. But even low-level childhood exposure to lead can have harmful consequences, including the possible development of seizures, learning disabilities, and behavioral problems.

While old pipes are at the root of Sebring’s problems, decades of unregulated mining were the problem for Phil and Carrie Berresford. In 2009, the couple moved to Navarre, Ohio, hoping to trade the busy pace of the city for a quieter country home. But when they turned on their faucets, their tap water was orange.

After testing the water, officials blamed acid mine drainage for the problem. After years of poor mining practices, many rural Ohio communities live with water that has unsafe levels of iron, sulfate, or other mineral compounds. But Sebring and Navarre aren’t the only Ohio cities with hazardous tap water. In 2015, 2.96 million residents were served by contaminated community water systems, putting over a fourth of the state’s population at risk.

7. Washington

Washington is known for its nature-loving population, and cities like Seattle are leading the nation in sustainability. The controversial “raw water” trend is popular in the northern state, and many of its residents make efforts to live eco-friendly lives.

But step outside city limits, and life looks different. Years of historically low snowpack on the Rocky Mountains means the rivers are beginning to run dry. But Washington’s water crisis isn’t limited to water quantity — the state has some of the nation’s worst water quality.

Chromium, chloroform, arsenic, uranium, nitrate, radon, and radium are just a few of the contaminants in Washington water, and in many communities, one or more are above the national safety levels. Almost all of the pollutants are known carcinogens, but the chemicals may also lead to developmental issues, liver damage, and reproductive difficulties.

In total, almost three million Washington residents were served unsafe water in 2015, which is over 40 percent of the state population.

6. Puerto Rico

Beautiful Puerto Rico is known for stunning beaches and architecture. But since hurricanes Irma and Maria hit in 2017, living conditions on the island have been bleak.

The storms wreaked massive damage through the island, shutting down infrastructure and tourism for months. Still, electrical outages and unreliable generators mean that running water isn’t guaranteed and is often discolored and filled with sediment when it does run. The government has warned people to boil it thoroughly for three minutes before using.

But even before the hurricanes, nearly all of Puerto Rico’s water violated federal standards. In 2015, the NRDC reported that 3.46 million Puerto Rico residents were served with unsafe water — 99.5 percent of its total population.

As the island slowly recovers from the hurricanes, its water conditions are slowly improving as well, in part because of widespread distribution of water filters.

5. Georgia

The sunny southern state of Georgia leads the nation in peanut, pecan, and peach agriculture, and is an increasingly important urban center as well — Atlanta is one of the country’s fastest-growing metro areas, and transplants from around the nation are flocking to the sprawling city.

But the state’s water quality is some of the nation’s worst. With polluted rivers, streams, and wells, it’s no wonder that much of Georgia’s drinking water doesn’t pass national standards. In some areas, chloroform, radium, bromate, chromium, chlorate, arsenic, or radium levels are well above legal guidelines. Total trihalomethanes (THMs), which may have links to skin cancer, bladder cancer, and fetal development issues, were also found in some water systems.

According to national reports, in 2015, a total of 3.86 million Georgian residents drank unsafe water.

4. New Jersey

New Jersey is one of the country’s top industrial centers. But the state’s urban sprawl comes with some dangers. Smog is a regular occurrence along the shorelines, triggering asthma attacks and damaging lungs. New Jersey air consistently ranks among the most polluted in the United States, and it has water quality to match.

PFCs are synthetic chemicals used for their grease, water, and heat-resistant properties. However, researchers have realized that PFCs are also highly toxic. Although PFCs are phasing out of production, they continue to persist in water systems and may cause cancer, liver damage, and birth and developmental issues. According to recent estimates, one in five New Jersey residents regularly drinks water contaminated with PFCs.

Other water contaminants include lead and chlorine, leading to 4.49 million New Jersey residents being exposed to unsafe water — over half of the state’s population.

3. Pennsylvania

With a rich history and a flourishing job market, the Keystone State is attracting new residents from all corners of the nation. To the casual observer, Pennsylvania’s beautiful countryside, gentle mountains, and diverse cities make it an ideal place to settle. However, Pennsylvania has a long history of water pollution.

Pennsylvania’s economy relied heavily on coal mining for decades. But unregulated mining practices led to a steady flow of pollution, producing black snow and rust-colored streams. Up to 20,000 miles of streams do not meet federal standards for fishing and swimming. Over 200,000 abandoned gas and oil wells dot the landscape, leaching contaminants into groundwater. Along with toxic chemicals, sewage regularly overflows in some areas during hard rains and washes into river systems.

For some communities, life in rural Pennsylvania has been deeply affected by fracking — a common problem concerns the well water, which can be discolored and odorous. Nearly six million Pennsylvanian residents are served with unsafe water systems, and while the state continues to enact new policies, conditions remain largely the same for many small communities.

2. Florida

The Sunshine State is known for sprawling beaches and world-renowned parks, drawing millions of tourists each year.

But in 2018, the water conditions of Florida faced two ecological emergencies. Red tide microorganisms drifted into the Gulf of Mexico, and blue-green algae overflowed into rivers, lakes, and the ocean. The combination of both eco-disasters killed large amounts of marine life, and it has turned national attention to the state of Florida’s waters.

An overabundance of fertilizer and other pollutants led to the freshwater algae blooms, which seem to get worse every year. Hurricanes and storms cause floods that send contaminants into the water systems, further damaging the state’s drinking water. In some areas, Florida water has registered high counts of coliform bacteria from human waste or unsafe levels of copper and lead.

In total, 7.5 million Floridians access water from systems that violate the Safe Drinking Water Act, meaning that many residents face water crises from both the sea and their faucets.

1. Texas

Texas leads the nation with GDP growth and job creation, but it also tops the list with the worst public water ratings in the United States.

The most polluted water systems are in the state’s small rural communities, where resources are scarce, and populations are often around 100 people per provider. Lead, radiation, and arsenic are among the top pollutants, partly due to old pipes and water systems, and partly because of contaminants spilled directly into waterways.

Roughly 12.07 million Texans are served with unsafe water, and the quality doesn’t seem to be improving — the latest reports say that Texas still has the country’s most radiated drinking water.

How Can I Find out If My Home Has Poor Water Quality?

If your state made the list with some of the worst water quality, don’t worry — you can take action to improve your area’s drinking water.

Here are a few steps you can take to determine the safety of your water.

1. Ask Your Provider

Before testing the water yourself, contact your local water provider. Ask them what tests have been done on your water and when they were performed, along with the results.

Your provider can give you detailed information about the levels of common contaminants such as arsenic, lead, or PFCs. Contacting your provider gives you a valuable starting point — even if you wish to conduct further tests, you will have an idea of what you’re looking for.

2. Send Samples for Testing

For the most trustworthy results, send off a sample of your drinking water to a certified water-testing laboratory. Experts can run a series of professional tests on your sample, looking for hard-to-detect chemicals such as PFCs.

Typically, laboratories will examine the amounts of chlorine, pesticides, lead, bacteria, and volatile organic compounds in your water, along with pH levels. They can look for other compounds at your request, giving you a thorough report on the quality of your drinking water.

3. Test Your Water at Home

Home testing kits are less precise than professional laboratory testing, but they can provide information about the general state of your water.

You can purchase kits from a variety of different manufacturers, but they all operate similarly — you will take a test strip, expose it to water, and note what color they turn. The kit will come equipped with a color chart matching different tones to different chemicals.

Test your water multiple times to make sure the results are consistent. If any chemical registers in a hazardous amount, contact your local water provider.

4. Invest in a Filter

You can avoid most toxins and contaminants with a high-quality water filter.

It might take a long time for the quality of your water to change. The best and most practical way to reduce pollution in your drinking water is through a carbon block filtration system. Using microscopic filtration technology, carbon block filters cleanse your water of many impurities without requiring you to re-route your water supply.

From whole-house systems to small models that sit on your countertop, carbon block filters come in a wide range of sizes and designs so you can find the option that best suits your home
