What are the source of water supply?

there are three main sources of watter :

1- Rain

2- Surface water : Oceans, Rivers and streams , tanks , ponds & lakes

3- ground water : shallow wells, Deep wells , Springs

1. Rain

Rain is the prime source of all water. A part of the rain water sinks into the ground to form ground water; part of it evaporates back into atmosphere, and some runs off to form streams and rivers which flow ultimately into the sea.

Some of the water in the soil is taken up by the plants and is evaporated in turn by the leaves. These events are spoken of as "water cycle".

Characteristics of rain water:

Rain water is the purest water in nature. Physically, it is clear, bright and sparkling. Chemically, it is very soft water containing only traces of dissolved solids (0.0005 percent).

Being soft, it has a corrosive action on lead pipes. Bacteriologically, rain water from clean districts is free from pathogenic agents.

Impurities of rain water:

Rain water tends to become impure as it passes through the atmosphere. It picks up suspended impurities from the atmosphere such as dust, soot and microorganisms and gases such as carbon dioxide, nitrogen, oxygen and ammonia.

Gaseous sulphur and nitrogen oxides are emitted from power plants that use fossil fuels. These gases react with atmospheric water, forming dilute solution of sulphuric and nitric acid. The precipitation of these acids (acid rain) has begun to have serious impacts on surface water quality and on plants etc..

2. Surface water

Surface water originates from rain water. It is the main source of water supply in many areas. Examples of surface water include rivers, tanks, lakes, man-made reservoirs and sea water.

Surface water is prone to contamination from human and animal sources. As such it is never safe for human consumption unless subjected to sanitary protection and purification before use.

Characteristics of surface water:

Surface water picks up the characteristics of the surface over which it passes. If water flows across a parking lot, gasoline, oil, and other contaminants may be carried by or dissolved into the water.

Water may pick up fertilizers, road salts, radioactivity, and biological contaminant from farms, as well as countless other biological, physical, and chemical pollutants.


Many rivers furnish a dependable supply of water. The chief drawback of river water is that it is always grossly polluted and is quite unfit for drinking without treatment.

Characteristics of river water:

River water is turbid during rainy season; it may be clear in other seasons. Clarity of water is no guarantee that the river water is safe for drinking. River water contains dissolved and suspended impurities of all kinds. The bacterial count, including the human intestinal organisms may be very high.

Impurities of river water:

The impurities of river water are derived from surface washings, sewage and sullage water, industrial and trade wastes, and drainage from agricultural areas.

Self-purification of river water:

Certain amount of self-purification occur in river water by natural forces of purification such as dilution, sedimentation, aeration, oxidation, sunlight, plant and animal life ,but these agencies are not sufficient to render the water potable. River water needs purification before it can be used for drinking purposes.

Sea water:

Though this source is plentiful, it has great many limitations. It contains 3.5 percent of salts in solution. Desalting and demineralization process involves heavy expenditure. It adopted in places where sea water is the only source available.

3. Ground water

Rain water percolating into ground constitutes ground water. Water used by humans comes mainly from land. It is now realised that there is a limit to ground water in the world.

Ground water is the cheapest and most practical means of providing water to small communities. Ground water is superior to surface water, because the ground itself provides an effective filtering medium.

The advantages of ground water are:

(1) It is likely to be free from

pathogenic agents;

(2) It usually requires no treatment;

(3) The supply is likely to be certain

even during dry season;

(4) It is less subject to contamination

than surface water.

The disadvantages of ground water are:

(1) It is high in mineral content, e.g.,

salts of calcium and magnesium which increase the water hard;

(2) It requires pumping or some arrangement to lift the water.


Traditionally wells are an important source of water supply. Even today, they are an important source of water supply in many communities. Technically, wells are of two kinds-shallow and deep.

(1) Shallow wells:

shallow wells tap subsoil water i.e. the water from above the first impervious layer in the ground. They provide limited quantities of water, and the water is easy to be polluted unless care is taken in well construction.

(2) Deep wells:

A deep well is one which taps water from the water-bearing stratum below the first impervious layer in the ground. Deep wells are usually machine-dug and may be several hundred meters deep. Deep wells furnish the safest water, and are often the most satisfactory sources of water supply.


When ground water comes to the surface and flows freely under natural pressure, it is called a "spring". Springs may be of two types------shallow springs and deep springs. Shallow springs dry up quickly during summer months, whereas deep springs do not show seasonal fluctuations in the flow of water.

In some geographic areas, springs constitute an important source of water. Springs are simpler to exploit, as no pumping is needed to bring the water to the surface. Springs are exposed to contamination.

Water Pollution

How do humans pollute water?

Humans pollute water in the following ways:

1. Discarding objects, appliances, oil or other waste into the bodies of water. That kills organisms and their habitats. The forms this take vary. Someone may back up to a bridge with a pickup truck and throw a refrigerator into a lake. Or people may walk or drive on a bridge, or ride in a boat, and throw their trash in the water. Sometimes ships may deliberately dump cargo into the ocean, and people wonder at times why drug needles and other medical waste end up on beaches.

2. Using jet ski's and boats. These vehicles often leak fuel, grease, and oil, and it goes into the water. There is also the exhaust, and since pump water usually comes out with the exhaust, some of the fumes and soot enter the water.

3. Dumping sewage or chemical waste into bodies of water. Sometimes it is an improper sewage connection or groundwater seepage. Sometimes this takes the form of a buried pipe which drains into the water. Other times, it is people with tankers or with tractor-trailers dumping toxic cargo into the water.

Why is oil and water called heterogeneous mixture?

in general hetero- means different and homo- means the same. -geneous in this case can be defined as "in nature." In this case heterogeneous means different in nature. So they are have opposite properties. Water and ethanol are homogeneous. That's why it is hard to mix water and oil together, but it's easy to mix your favorite alcoholic beverage with water.

There can be many ways we humans pollute Salt or Fresh water.

I'm only going to name a few:

  • Oil spills
  • Dumping Garbage into the water
  • Fertilizer runoff

What type of air pollution could cause corrosion?

Acid rain caused by SOx and NOx in the air can (and does) cause corrosion of metals and stone (limestone and marble) as ell as concrete.

Hydrogen sulfide can cause corroding of metals like iron and tarnish silver.

Salt spray can corrode iron and steel and erode concrete

Any material which is a powder or fume can deposit on surfaces and cause water and dew to wet the surface for a longer peiod of time - wet metals interact with oxygen and corrode faster. == ==

What harm can dumping of untreated sewage into river cause?

One of the main concerns of dumping untreated sewage is bacteria levels. Sewage is teaming with bacteria far above a safe level. When this is poured into a river it can create many problems. Some of the most prominent are that it makes the water dangerous swim in and it makes the water undrinkable. Also, it can kill the plants and animals living in the river and make the remain life sick and dangerous to eat because of the bacteria and parasites that once lived in the sewage and now live in the fish.

Why point-source pollution is easier to control than non point-source pollution?

point-source of pollution is easy to because we can control it at the same site where the pollution source is originated.

Nonpoint source pollution is difficult to regulate.

How are humans responsible for pollution?

Humans can be responsible for a few ways of pollution....We pollute by having cars that release harmful gases in the air. Farmers pollute soil by using pesticide to prevent insects from using minerals in soil, which kills the plants. Herbivores can't eat the plants, and then carnivores can't eat the herbivores. This causes decreasing plants and animals.

What is water pollution?

Water pollution means many material added to water so it's unsafe for drink. All unwanted material make pollute water so the water is harmful to plant or animals. Water can pollute in many ways. Now a days population explosion is very harmful for water. Many villagers build their toilet bank of the river and put their wast in to the river Many factories put their wast in to the river. So river water is not suitable for use irrigation. Specially this problem is sever for poor and developing countries in the world. So we have to need awarness to prevent this unwanted situation. It you want to drink pure water you can buy water purifier. I know about a cheap price water distiller.

Deforestation and Habitat Loss

How does deforestation cause water pollution?

Deforestation causes water pollution because when there are no trees left to block the rain fall the rain falls directly on to the soil and washes it in to the rivers, which take it on to the seas and oceans. The soil may contain chemicals that pollute the water.

What are the negative and positive effects of tourism in France?

Well the positive side is that the country gets a high income from tourism because over 70 milion foreign tourists arrive in France each year! genarating alot of money for the country this can pay for things such as new buildings, repairs and keeps France in the trayd game. The negative side, loads of plains go to and from France producing lotscarbon dioxide poluting the earth, carbon heats up the world how? by creating a blanket of carbon surounding the earth aloing heat and light to entre the earth but only a % to escape thus heating the earth. oh and by the way ime from PGS, 9S and 14, trying to do ma geography homework lol. hope this helped!!

What should be the conclusion for the project on pollution?

Much is being done to control, monitor and rectify damage done by pollutants. The problems are diverse and some are only being recognised but it is important to keep a close control over pollutants so that we can maintain the environment in an acceptable condition for future generations.

We need to take pollution issue seriously because ignorance is certainly not the proper way to go. The stakes are really high and world needs to wake up and start acting right now because environmental issues are constantly growing in both number and size.

Aren't we aware of the different problems occurring in our nature, especially in different bodies of water? We, humans are only creating problems that consequently we will also carry the burden of these problems. We all know how important environment is. Act right now.
