Water..! water..! water...?

Question

Do you know where does our drinking water come from? And please if you do have web resources or any sources on the net, please share it with me...

Answer 1

Drinking water comes from varied sources, groundwater, lakes, rivers, but the real source of the sources this is mainly the rain, and the rain comes from the evaporation of the ocean. Water in vapor is mandatorily not salted, even if coming from the sea (except in some costal winds weired with water), effectively oceans loose their water and concentrate their salt and are continuously diluted again by rivers coming to them (or salt can concentrated so much and be isolated in some coasts or salted closed seas, that oceans loose like that a part of their salt). Evaporated water form clouds upon seas and oceans, these clouds follow the direction of winds, high or low pressure, systems of cyclons and anticyclons, and some arrive on the firm land and then according to temperature, pressure, relief, the vapor (water gas) transforms in liquid droplets and fill again our rivers, snow reserves, underground water, etc... There are water clouds coming from firm lands as well formed by evaporation of lakes and rivers, and the respiration of the trees, but they are of lesser importance.
For the reference, please search on the net : cycle of water .
Because I too have no time to search and give the reference, but I studied that in environmental superior studies...
Bye, good luck for the exam tomorrow !

Answer 2

It depends on where you live. In my county, everyone drinks groundwater. We have city wells for public supply and private wells in rural areas. Bigger cities, like Chicago, and smaller communities along lakes, rivers, etc. get drinking water from surface water bodies. Many times, rivers are damned to provide reservoirs of water. Check out EPA.gov for more drinking water information.

Answer 3

My drinking water comes from a tap, although I know some people like to pay extra for water that comes in plastic bottles.

Some people are weird, though.

Answer 4

Water is absorbed from the soil and moves up the plant due to capillary work. It then moves out into the leaves and is absorbed by the sun. You can see if happen if you cut the bottom couple inches off of a stick of celery and place it in a glass of water with food coloring. The colored water slowly moves up the stalk and colors the celery leaves. Water travels through plants by absorbing through the roots and traveling through the plants' vascular system. Surface tension and pressure help the water move its way through the plant.

Answer 5

Well, I know in my hometown it comes from the local river. I think it just depends on where you live.

Answer 6

Mainly mountain streams and/or groundwater
