What is pollution?
Water pollution is the pollution of bodies of water, usually due to human activity. Reservoirs include, for example, lakes, rivers, oceans, water, and groundwater. Pollutants cause pollution when they enter the natural environment. For example, the discharge of untreated wastewater into natural waters can damage the aquatic ecosystem. As a result, it can cause health problems in people who are dehydrated. You can use contaminated water for drinking, bathing, or watering. Water and pollution are the leading causes of death and disease in the world, e.g. Due to waterborne diseases.
What are the causes of the pollution?
There is a particular risk of water pollution. Known as the "universal solvent", water dissolves better than any liquid on earth. That's why we have coal support and big blue waterfalls. That's why the water is so polluted. Agricultural, urban, and industrial toxins are easily digested and broken down, resulting in water pollution.
Categories of Water Pollution
Here are some categories of water pollution.
Surface water, which covers about 60% of the earth's surface, fills our oceans, lakes, rivers, and all those blue spots on the world map. Over 100% of the freshwater that enters the American homeland comes from freshwater sources (excluding the sea) in surface waters. However, a large pool of this water is in danger. According to a recent national water quality survey by the United States Environmental Protection Agency, half of our rivers and streams and a third of our lakes are polluted and unsuitable for swimming, fishing, and drinking. Food contaminants, including nitrates and phosphates, are a major source of pollution in these freshwater sources. Although plants and animals need these nutrients to thrive, they have become a major pollutant due to the excessive flow of agricultural waste and fertilizers. There is also a significant proportion of toxic food from municipal and industrial waste. There are all kinds of random trash dumped straight into the water by industries and individuals.
When it rains and penetrates deep into the ground, cracks, crevices and dangerous spots (mostly aquifers) fill with water, making groundwater one of the most important natural resources we have. Approximately 40% of Americans depend on groundwater for their surface use.
Eight percent of marine pollution occurs on land - both on the coast and in remote areas. Pollutants like chemicals, nutrients, and heavy metals flow from fields, factories, and cities to our streams, rivers, and streams. From there they travel by sea. Sea debris - especially plastic - has already been blown away or washed away from storm sewers. Our oceans sometimes spill oil and are damaged by small to large leaks and are constantly submerged in carbon dioxide from the air. The oceans absorb a quarter of all human-made carbon emissions.
When the pollution comes from a single source, we speak of a pollution source. For example, sewage that is legally or illegally discharged from producers, refineries, or sewage treatment plants, as well as illegal sewage and waste from septic tanks, chemicals, and water wells. The EPA manages point source contamination by restricting the flow of water through a device directly into the body. Although point source pollution originates in a specific area, it can affect rivers and oceans for miles.
Not only is agriculture the largest consumer of freshwater in the world, but agricultural and animal products also make up 70 percent of the world's surface water supply and are a major source of water pollution. Agriculture is the main cause of the water crisis worldwide. Agricultural pollution in the United States is the main source of pollution in rivers and streams, the second largest in wetlands, and the third largest source of water in lakes.
Sewage and wastewater
The water used is dirty water. Our bottles, showers and toilets (the concept of sewage) and our commercial, industrial and agricultural activities (metal objects, solvents and toxic sludge). The term refers to the rainwater runoff that carries road salt, oil, grease, chemicals and dirt to our waterways when it rains.
According to the United Nations, 80% of the world's wastewater is returned to the environment without treatment or reuse, compared to 95% in some less developed countries. Sewage treatment plants in the United States use 34 billion gallons of wastewater per day. These devices reduce the amount of water that flows through the water before the release of pollutants such as germs in sewage, phosphorus and nitrogen, and heavy metals and toxic chemicals in industrial waste. If everything is in order. However, the EPA estimates that our country's aging and easily floodable wastewater treatment plant releases more than 850 billion gallons of treated wastewater each year.
How does pollution affect?
About human health
According to a study published in The Lancet which found that 1.6 million people died from water pollution in 2015. Contaminated water can make you sick too. Every year unsafe water makes about 1 billion people sick. Low-income businesses are at risk as their homes are often close to polluting industries.
Bacteria and viruses that cause disease from human and animal waste are the main cause of disease in contaminated drinking water. Cholera, gonorrhea, and typhoid are among the most dangerous water-borne diseases. The EPA estimates that 3.5 million Americans are infected with hepatitis each year, including rashes, pink, respiratory and sewage infections.
About the environment
A healthy ecosystem depends on a complex network of animals, plants, bacteria and cookies. They communicate with each other directly or indirectly. The loss of any of these organisms can lead to a chain reaction that affects the entire aquatic environment.
When water pollution causes disease in lakes or the marine environment, the application of newly applied nutrients stimulates the growth of plants and algae, resulting in decreased oxygen levels in the water. This lack of oxygen, known as eutrophication, can suffocate plants and animals, creating a "dead zone" where aquatic life is practically zero. In some cases, these harmful agglomerates can also produce neurotoxins that affect wildlife, from whales to sea turtles.
Marine ecosystems are also threatened by marine debris, which can lead to drowning, drowning, and starvation of animals. Much of this mighty debris, like plastic bags and soda cans, is dumped into water and storm sewers and eventually sinks into the ocean, turning our oceans into trash, and sometimes forming solid patches of trash. “Indoor fishing gear and other types of litter are responsible for the loss of over 200 different marine life.
What can you do to avoid water pollution?
- Municipal and industrial water treatment plants prior to the disposal of bodies of water.
- Appropriate storage, recycling and disposal.
- Apply "clean technology" to industrial equipment.
- Separate the sewer line so as not to impair the clean drinking water supply.
- Filter device for clean drinking water.
- Water conservation needs to be considered in order to avoid future water crisis. Here are some helpful tips.
- Don't pour water down the drain, water your plants or your garden.
- Build drip taps, one drop per second uses 2700 gallons of water per year.
- If you are bored, take a shower and leave it on the water
- Turn off the water when you brush your teeth or wash your face.
