How does groundwater pollution occur? 2. For a planet where water covers 70 percent of the surface, Earth certainly makes its residents work hard for a drink. Aside from fish and other saltwater-sipping sea life, most of us have to share what little freshwater we can find on land. And that's no small task. Only 3 percent of all water on Earth is freshwater, more than two-thirds of which is locked up in glaciers and ice caps. Of the other third, barely a trickle collects on the surface — lakes, rivers, streams and swamps represent less than 0.5 percent of all freshwater worldwide.

POLLUTION AND HOW IT AFFECTS WATER If you don't think pollution affects your life or are unsure just how, the best place to start is with your drinking water. Pollution of drinking water causes many deaths and much illness among urban residents all over the world. Particularly in developing countries, urban water supplies are often fouled with wastes, and clean water is scarce.

- Types of water pollution. Water pollution can come from a number of different sources. If the pollution comes from a single source, such as an oil spill, it is called point-source pollution. If the pollution comes from many sources, it is called nonpoint-source pollution.Most types of pollution affect the immediate area surrounding the source.Sometimes the pollution may affect the environment hundreds of miles away from the source, such as nuclear waste, this is called transboundary pollution.ater pollution can come from a number of different sources. If the pollution comes from a single source, such as an oil spill, it is called point-source pollution.

Stream Pollution Stream Pollution. Nearly everything that can be found on land eventually makes its way to a stream. This is because every bit of ground on Earth is a part of some river's watershed. Water flows downhill. Whether the water comes from rain, a hose, or a pipe, whatever doesn't sink into the ground will flow into the nearest stream.

Substances Causing Pollution in Rivers Substances Causing Pollution in Rivers. The substances that cause water pollution can be divided into two main groups - germs and chemicals. Germs are small organisms that cause diseases such as malaria, cholera and bilharzia, and chemicals are poisons, which are mainly produced by industries. Natural chemicals are found everywhere in the environment. Unfortunately, many of the chemicals that are produced by industries are not found naturally in the environment or are only found in very small amounts. Different industrial processes produce different types of products and waste products.

- The two categories of water pollution are point sourcepollution and nonpoint sourcepollution. Point source pollution can be tracked to find where it comes from. It can be identified and stopped. Nonpoint source (NPS) pollution comes from sources that are hard to locate and identify. Water Cycle Transpiration - Plants “breathe” water in the form

Water pollution: an introduction Factories are point sources of water pollution, but quite a lot of water is polluted by ordinary people from nonpoint sources; this is how ordinary water becomes waste water in the first place. Virtually everyone pours chemicals of one sort or another down their drains or toilets.

- Types of water pollution. There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution. Some wastewater, fertilizers and sewage contain high levels of nutrients. If they end up in water bodies, they encourage algae and weed growth in the water. This will make the water undrinkable, and even clog filters.

- Non-Point Source Pollution. Water Pollution. As water from rainfall and snowmelt flows over and through the landscape, it picks up and carries contaminants from many different sources. This is called Non-Point Source pollution. This polluted water ends up in streams, lakes and the ocean by flowing directly in or by going through untreated storm drains. Water also carries pollutants into underground drinking water as it soaks into the ground. 40% of all lakes and streams are too polluted to use for fishing or swimming in the United States.

Environmental Pollution In other words, pollution takes place when nature does not know how to decompose an element that has been brought to it in an unnatural way. Pollution must be taken seriously, as it has a negative effect on natural elements that are an absolute need for life to exist on earth, such as water and air. Indeed, without it, or if they were present on different quantities, animals – including humans – and plants could not survive.

Water Pollution Types of Water Pollution. Toxic Substance -- A toxic substance is a chemical pollutant that is not a naturally occurring substance in aquatic ecosystems. The greatest contributors to toxic pollution are herbicides, pesticides and industrial compounds.he sources of water pollution are categorized as being a point source or a non-source point of pollution. Point sources of pollution occur when the polluting substance is emitted directly into the waterway. A pipe spewing toxic chemicals directly into a river is an example.

Pollution Facts & Types of Pollution Adequate sanitation helps to keep sewage and other contaminants from entering the water supply. According to National Oceanic and Atmospheric Administration (NOAA), 80 percent of the pollution in marine environments comes from the land through sources such as runoff. Water pollution can severely affect marine life.arming water can also be harmful. The artificial warming of water is called thermal pollution. It can happen when a factory or power plant that is using water to cool its operations ends up discharging hot water. This makes the water hold less oxygen, which can kill fish and wildlife.

Land pollution Air pollution doesn't remain air pollution forever. Ideally it disperses, so the concentration of problematic chemicals becomes so low that it no longer constitutes pollution. Sometimes, though, it falls back to the ground and becomes either water pollution (if it enters the oceans, rivers, and lakes) or land pollution. Pollution created (deposited) in water or land from existing pollution in the air (atmosphere) is known as atmospheric deposition.
