The original focus of most water quality improvement programs was on such conventional pollutants as dissolved oxygen, fecal coliform bacteria, suspended sediment, dissolved solids, and phosphorus. Although pathogens in inadequately treated drinking water are still the greatest public health concern related to drinking water, increased industrialization, the widespread use of chemicals in industry and agriculture, and the disposal of large volumes of industrial wastes have drawn attention to the importance of protecting drinking water from contamination with chemical agents.

Over 60, chemicals are now being used by industry and agriculture. Accordingly, such substances as synthetic organic chemicals, solvents, pesticides, metals, cleaning preparations, and septic tank de-greasers can pollute both surface and ground waters that are sources of drinking water.

What effects does water pollution have on human health?

Regret for the inconvenience: we are taking measures to prevent fraudulent form submissions by extractors and page crawlers. Received: January 30, Published: February 3, Citation: Yacout MHM. Sources of water pollution and procedures necessary for the prevention of pollution a review. J Dairy Vet Anim Res. DOI:

Water pollution is the contamination of water bodies , usually as a result of human activities. Water bodies include for example lakes , rivers , oceans , aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream.

The planet keeps nudging us with increasingly extreme droughts, reminding us that water is life. It is an essential resource upon which all living beings depend and it is crucial to all social and economic development, as well as energy production and adaptation to climate change. Nevertheless, we are now facing a gigantic challenge. How do we stop contaminating our rivers, seas, oceans, canals, lakes and reservoirs? Water pollution is endangering the health of millions of people around the world. The waters of the River Ganges flow clear and clean through the Indian city of Rishikesh at the gateway to the Himalayas. In these mountains, nobody would guess that this water will be transformed into one of the most heavily polluted rivers in the world, with faecal bacteria levels up to 31 million per millilitres.

Water Pollution: Everything You Need to Know

Water pollution occurs when a body of water becomes contaminated, usually by chemicals or microorganisms. Water pollution can cause water to become toxic to humans and the environment. Water is an essential resource for all life on Earth. If a water source becomes contaminated due to pollution, it can lead to health issues in humans, such as cancer or cardiovascular conditions. This article explores the causes of water pollution, how it can affect human health, and what people can do to help prevent it.

Water pollution , the release of substances into subsurface groundwater or into lakes , streams, rivers , estuaries , and oceans to the point where the substances interfere with beneficial use of the water or with the natural functioning of ecosystems. In addition to the release of substances, such as chemicals or microorganisms, water pollution may also include the release of energy , in the form of radioactivity or heat , into bodies of water. Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste , petroleum , and disease-causing microorganisms. Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances.

Without action, the challenges will only increase by , when global demand for freshwater is expected to be one-third greater than it is now.

You were introduced to wastes and pollutants in Study Session 1, where we discussed the interactions between humans and our environment. Pollution was defined as the introduction into the environment of substances liable to cause harm to humans and other living organisms. Many human activities pollute our environment, adversely affecting the water we drink, the air we breathe, and the soil in which we grow food. In this and the next study session we will look more closely at pollution.
