All You Need to Know About Water Pollution

Water pollution is technically a condition wherein the water is contaminated by anthropogenic substances. About 75% of the Earth's composition is composed of water, so water pollution is a global problem. Due to the contamination of waters, ecosystems gradually diminish. Several organisms die due to the toxicity of the water. Even humans suffer the same fate because there are people who barely have access to safe portable water. To date, the majority of deaths around the world were caused by water pollution diseases.

Various Causes of Water Pollution

Water pollution can be caused by various activities. Some of which are industrial-related activities, such as sewage treatment, product manufacturing and chemical use. Some can also be caused by floatables, such as garbage or objects from shipwrecks.

Effects of Water Pollution on the People and the Environment

Water pollution presents detrimental effects on the people and the environment. For example, due to water pollution, several aquatic species die. As a result, the cycle established in the ecosystem could soon be compromised. Organisms, including humans, would then have to search for other means to acquire safe water.

How is Water Cleaned for Human Use?

Water purification is the process by which contaminated water can be reused as drinking water. Various substances, such as bacteria, solids, minerals, and pollutants, are removed during the water purification process. The water purification process could involve any of the following methods: pre-chlorination, coagulation, aeration, filtration, etc.

Role of the Environmental Protection Agency (EPA) on Keeping Water Safe and Clean for the People

The Environmental Protection Agency was established to ensure that drinking waters are safe enough to maintain human health and the balance established in the ecosystem. EPA is also responsible for the implementation of the laws that protect the water habitats from contamination.

What We Can Do to Help Keep Water Safe and Clean

Whenever possible, it is important to use environmentally-friendly products so that the water won't be contaminated by unsafe chemicals. Secondly, it would be helpful if the banks of rivers could be provided with vegetation. In that way, storm water could be purified by plants before it would be discharged to the nearest river bank.
