Rain water Rainwater is the purest source of natural water. Rainwater is directly produced from water condensation in the presence of the sun. The water in lakes, rivers, and seas evaporates.

Groundwater feeds springs and streams, supports wetlands, helps keep land surfaces stable, and is a critical water resource. About 60% of the water that is taken from the ground is used for farming in arid and semi-arid climates, and between 25% and 40% of the world’s drinking water comes from underground.

3.1 Types of water source. In Study Session 1 you were introduced to the three main sources of water: groundwater, surface water and rainwater.

Answer. The main sources of water are surface water, groundwater and rainwater.

Here are some of the most effective water purification methods that have stood the test of time:

1. Boiling. The simplest method to purify water is to boil it for a good amount of time.
2. Water Purifier.
3. Reverse Osmosis.
4. Water Chlorination.
5. Distillation.
6. Iodine Addition.
7. Solar Purification.
8. Clay Vessel Filtration.

Tap water comes from one of two sources: surface water (including reservoirs, rivers, and lakes) or groundwater (from artesian and deep wells).

Potable water means drinking water. Well, river and lake contain drinking water as these all contain either rainwater and groundwater which is suitable for drinking. The sea which contains salty water that is not suitable for drinking is not a source of potable water.

Ice (solid) Ice is water in its solid form.

Explanation: Fresh surface water is maintained by rainfall or other precipitation, and it’s lost through seepage through the ground, evaporation, or use by plants and animals. Man-made bodies of water are not considered surface water since they generally rest on artificial surfaces, not the ground itself.

Most people don’t realize that there are three different types of water: utility grade, working grade, and drinking water. It’s helpful to be aware of these different types of water, so that we understand how they are used and to better educate us on the level of treatment recommended for each kind.

Surface water originates mostly from rainfall and is a mixture of surface run-off and ground water. It includes larges rivers, ponds and lakes, and the small upland streams which may originate from springs and collect the run-off from the watersheds.

Oceans, streams, lakes, ponds, and other bodies of water found on the Earth’s surface are considered surface water. This includes water vapor in the air, such as clouds. In the image below, the ditch, the sea, and the stream are all examples of surface water.

All types of liquid surface waters are considered—rivers, reservoirs, lakes, bogs. The basic terms used to describe these water bodies are defined. Their types and classifications are given, and data are presented on the largest rivers, lakes and reservoirs.

The sea which contains salty water that is not suitable for drinking is not a source of potable water.

Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks. Water that seeps deep into the ground is called groundwater. Surface water and groundwater are reservoirs that can feed into each other.

Water that occurs below the ground and is brought to the land surface by wells or springs is referred to as groundwater. Groundwater comprises 97 percent of fresh water not tied up as ice and snow in polar ice sheets, glaciers , and snowfields. This greatly exceeds the amount of water in streams, rivers, and lakes.

What is another word for surface water?

The main uses of surface water include drinking-water and other public uses, irrigation uses, and for use by the thermoelectric-power industry to cool electricity-generating equipment.

Water from rivers, lakes, ponds and streams can contain bacteria, parasites, viruses and possibly other contaminants. To make surface water fit to drink, treatment is required. Remember, we use our drinking water in many different ways. If the water is contaminated, this may put you at risk.
