Water pollution is a serious global issue that threatens the health of humans, animals, and our environment. Unfortunately, water pollution has become an increasing problem in many parts of the world due to industrialization and population growth. And thanks to the cyclical way H2O moves between our ecosystems and our supply of drinking water, this epidemic of pollution can have a very direct impact on the safety of water in our homes. Knowing water pollution facts helps us to understand why it’s important to protect our water sources from contamination, both by reducing pollution and by filtering the water that enters our homes.

1. Only 12% of Oil in the Oceans Comes from Oil Spills

Oil spills have long been a major source of water pollution. However, water pollution facts show that only 12% of the oil contaminating the world’s oceans actually comes from oil spills. The rest is caused by land-based sources such as urban runoff and disposal of industrial waste into water sources, making it difficult to curb this type of pollution and ensure water safety.

2. Millions of Marine Animals Die from Water Pollution Each Year

Not only does water pollution affect water quality, but it also has devastating effects on aquatic life. More than a million marine animals die each year due to plastic pollution alone, not even taking other water contaminants into account. Pollutants like nitrogen and phosphorus can even create “dead zones” in water sources, where fish cannot survive.

3. There Are 500 “Dead Zones” in the World’s Oceans

Water pollution has dramatic effects on our ecosystems and biodiversity. One of the most noticeable impacts is the formation of “dead zones,” which are areas where sea life and coral reefs have been utterly destroyed due to water pollution. Shockingly, there are currently more than 500 dead zones across the world’s oceans, with new ones being discovered every year.

4. Less than 1% of the World’s Water Is Drinkable

When it comes to water pollution facts, one of the most alarming is that less than 1% of the world’s water supply is drinkable. This includes both surface and groundwater sources that are safe for human consumption. This water scarcity creates a major issue for many parts of the world, particularly in developing nations where water sources are often contaminated by industrial and agricultural runoff.

5. 1 in 3 People Can’t Access Clean Water

Clean water is essential for human health and well-being. Yet water pollution has made it increasingly difficult to access safe drinking water. According to the World Health Organization, around a third of the world’s population does not have access to clean water, and this number is expected to increase as water pollution worsens. Altogether, that’s more than 2 billion people without a safe, clean water source.

6. Water Pollution Caused 1.4 Million Human Deaths in 2019

When people can’t access clean, safe drinking water, this forces many to rely on contaminated water sources just to survive. This can cause exposure to dangerous heavy metals, chemicals, and potentially lethal bacteria and diseases, such as cholera. As The Washington Post reports, this can lead to a devastating loss of life, such as the more than 1.4 million people who died from water pollution in 2019.

But this isn’t only an issue in areas without sufficient infrastructure. In many cases, people may also continue to use everyday water sources without knowing that they are potentially dangerous.

7. Millions of Americans Live with Contaminated Water

In the United States, water pollution remains a serious issue. Millions of homes in America have water that is contaminated with lead, arsenic, and other hazardous substances — and many residents may not even realize that they’re subject to an unsafe water source. This contaminated water can cause chronic health problems for those who drink it or are exposed to it, such as skin and eye irritation, respiratory issues, and even cancer. And authorities are now raising the alarm around dangerous chemicals called PFAS, which may be widespread in American water systems.

How to Ensure Clean Water in Your Home

Water pollution facts can be overwhelming, but there are ways to ensure that water in your home is safe and clean. Start by checking for water contamination warning signs such as an odd smell or taste, discoloration of water, or particles suspended in the water. That said, not all contaminants can be perceived by our senses. That’s why water testing is so important. Fortunately, there are free resources to get your water checked and find out about the best solutions for your home and budget.
