The Water Cycle - What is the Water Cycle - The water does not just magically appear in either place; it is a long process. One of the most interesting things about water is that there is not really a beginning or an end to that process - there is what is referred to as ‘the water cycle’ and it points to the fact that the water we have today is the same water that we have been using since the dawn of ages, it just keeps getting recycled. Let’s inject ourselves in to a part of the cycle that seems like a good starting point – rain. Rain water falls from the clouds, landing on our backyards, roof tops, roads, lakes, and rivers (and everything else). Here water can settle into the landscape (infiltration) or it can wash away (run-off). The water that is absorbed by the landscape works its way down through layers of leaves, dirt and rock until it runs into the water table or ground water (also called an aquifer). The water that washes away follows gravity down hills, into water drains picking up speed and debris as it goes; this water ends up washing into our streams and creeks causing them to fill up and flow faster. Our creeks start as small trickles that bubble up from the water table at a point called a ‘spring’. These trickles of water come together as they head downhill to the ocean with each merger they increase the amount of water that runs in them and they become creeks, streams, and rivers. This inner connection of hundreds or thousands of creeks, streams and rivers is called a watershed.

Water Cycle shows that all of our water is connected.

The Water Cycle

What is the Water Cycle

American Rivers



Where does our water come from?

And how did it get there?

For some folks the answer is the grocery store (and Fiji) but for most of us the answer is that it flows out of the tap when we turn it on.

Though the reality is that the water does not just magically appear in either place; it is a long process.

One of the most interesting things about water is that there is not really a beginning or an end to that process - there is what is referred to as ‘the water cycle’ and it points to the fact that the water we have today is the same water that we have been using since the dawn of ages, it just keeps getting recycled.

How the Water Cycle Works

Let’s inject ourselves in to a part of the cycle that seems like a good starting point – rain.

Rain water falls from the clouds, landing on our backyards, roof tops, roads, lakes, and rivers (and everything else).

Here water has two choices: it can settle into the landscape (infiltration) or it can wash away (run-off).

The water that is absorbed by the landscape works its way down through layers of leaves, dirt and rock until it runs into the water table or ground water (also called an aquifer).

The water that washes away follows gravity down hills, into water drains picking up speed and debris (leaves, trash, dirt, pet waste) as it goes; this water ends up washing into our streams and creeks causing them to fill up and flow faster.

But, where did that creek come from?

Our creeks start as small trickles that bubble up from the water table at a point called a ‘spring’.

These trickles of water come together as they head downhill to the ocean with each merger they increase the amount of water that runs in them and they become creeks, streams, and rivers.

This inner connection of hundreds or thousands of creeks, streams and rivers is called a watershed.

The water that flows in the Mississippi River (the largest river watershed in the country) past New Orleans could have started near Pittsburg, PA in the Ohio River or Bismarck, ND in the Missouri River or Oklahoma City, OK in the South Canadian River.

Everyone that lives in our watersheds needs some of that water to be clean enough to drink so they can live.

Some people, businesses, farmers, and towns use wells (holes drilled deep into the ground) to pull water from the underground water table.

This water is cleaned up as is filters its way down through the dirt, rock and clay of the earth’s crust.

It is critical for that water supply that there are areas that are clean and open enough for water to be able to be absorbed into the ground and that the ground that the water is moving through is clean.

Other communities use water pulled directly from our rivers for their drinking water.

In this case it is critical that the water that is washed into those creeks, streams, and rivers or that bubbles up from springs is as clean as possible before being pulled from the river.

Once a community system pulls that water from a river (and in some cases a well), the water is treated to federal and state required purity levels before being pumped and piped to our houses as clean drinking water.

It is only at this point that the water is able to come out of your tap when you turn the faucet on.

WATER PURIFICATION TECHNOLOGIES - People drawing water from private wells are responsible for assuring that their water is safe for consumption. The Environmental Protection Agency only requires testing of municipal water sources for about 80 of more than 75,000 known contaminants. The standards for safe drinking water are safe for a 175 pound healthy adult. Those standards may not be safe for children, pregnant and nursing mothers and adults with compromised immune systems. Municipal water supplies do not need to test for or eliminate many known contaminants that "do not present a health threat". These "secondary contaminants" DO make your water taste and smell bad, corrode your pipes, stain your sinks and tubs - and may stain your teeth or alter the color of your skin. There are many methods used to remove impurities and contaminants from water. Each of the water purification technologies is best at removing one type of contaminant from water, and may not be effective at all for others. Below is a short list of common water purification technologies and the contaminants that they remove.

There are many methods used to remove impurities and contaminants from water.
Each of the water purification technologies is best at removing one type of contaminant from water, and may not be effective at all for others.
Fact: People drawing water from private wells are responsible for assuring that their water is safe for consumption.
Fact: The Environmental Protection Agency only requires testing of municipal water sources for about 80 of more than 75,000 known contaminants.
Fact: The standards for safe drinking water are safe for a 175 pound healthy adult. Those standards may not be safe for children, pregnant and nursing mothers and adults with compromised immune systems.
Fact: Municipal water supplies do not need to test for or eliminate many known contaminants that "do not present a health threat". These "secondary contaminants" DO make your water taste and smell bad, corrode your pipes, stain your sinks and tubs - and may stain your teeth or alter the color of your skin.
Below is a short list of common water purification technologies and the contaminants that they remove.
Carbon Filtration 
Description
Water is passed through activated carbon filter cartridge. Carbon absorbs objectionable odors, flavors, organic compounds, and many hazardous chemicals.

Carbon absorption is one of the most widely used water filtration systems. There are two kinds of carbon filter systems - granulated carbon and solid carbon. A process of heat treating creates "activated" carbon with microscopic pores and fissures that trap chemical and organic impurities in a process that mimics the filtering properties of the earth.

The effectiveness of a carbon filter system depends on many factors, including the type and amount of carbon used, the way the filter is designed and the length of time that the filter has been in use.
Removes:
Hydrogen Sulfide, Radon, Chlorine, Volatile Organic Compounds, Pesticides, Benzene, Colors, Odors.
Advantages:
Removes dissolved organic compounds and some chemicals effectively. Works well in conjunction with other filtration systems. Removes objectionable odors and flavors
Disadvantages:
Most will not remove heavy metals. Filters must be changed or filtering capacity will be compromised
Particulate and Micro Filtration
Description
Micro filtration removes sediments and suspended materials from water by passing it through a porous filtering material. They do not remove very fine particles or dissolved substances and are often used before or after other filtration systems.

There are three types of mechanical microporous filtration systems: depth, surface and screen filters. Depth filters are often used to pre-treat water by removing up to 98% of the suspended impurities in water that might foul or clog other parts of the filter system. Surface filters remove up to 99.9% of suspended contaminants and may be used as a pre-filter or a final clarifying filter. Screen filters are placed at the end of the filtration system to remove the last remaining traces of resin, carbon and microorganisms.

Removes:
Sediment
Advantages:
Remove all suspended impurities larger than pore size
Disadvantages:  
Does not remove dissolved particles
.....................
Ultra Filtration
Description

Like Micro-filtration systems, the ultra filtration systems remove impurities from water by passing it through a "screen". The screen in this case is a semi-permeable membrane that effectively separates molecules in water, allowing certain molecules to pass through it while retaining others.
Removes:
Sediments and extremely fine particles, microorganisms
Advantages:
Highest quality water for lowest energy investment
Disadvantages:
May clog. Can be expensive if large amounts of sediment exist. Does not remove dissolved particles.
Reverse Osmosis
Description
Reverse osmosis works on the same principle as the body's cells - by filtering water through a semi-permeable membrane placed between a concentrated and a dilute solution. The diagram at left should help explain the process.

The simplest explanation is this:
When two solutions with differing concentrations are separated by a semi-permeable membrane, the solution with the higher concentration will infiltrate the solution with the lower concentration. That process may be reversed by applying pressure of some sort to the side that holds the more concentrated solution, forcing it through a membrane that will remove the impurities from the water.

The success of reverse osmosis is dependent on the quality of the permeable membrane. Those used in RO water filtration systems are capable of trapping salts, inorganic solutes and many organic compounds.

Reverse osmosis delivers high quality drinking and cooking water, but the volume of water needed to produce a usable amount makes it impractical to use for whole-house filtering. It's often combined with other types of water filtration for a complete water filtration solution.
Removes:
Lead, Sulfate, Calcium, Magnesium, Sodium, Potassium, Manganese, Aluminum, Chloride, Nitrate, Fluoride Boron, Most Microorganisms, Organic Chemicals.
Advantages:
Removes nearly all contaminants of all types to some extent. Requires little maintenance
Disadvantages:
Requires large volumes of water - it may take as much as 3 to 5 gallons of water to recover 1 gallon of usable water. Flow rate is limited to a certain amount of gallons per day.
Ion Exchange
Description

Water is percolated through a layer of resin beads that have a sodium exchange coating. As the water passes through the layer, ions in the water are exchanged for ions on the beads. The method is often used to "soften" water before other treatment methods by removing metals and minerals. It's particularly effective in conjunction with reverse osmosis and carbon filtration.
Removes:
Nitrate, Sulfate, Fluoride, Iron, Magnesium, Calcium, Manganese.
Advantages:
Removes dissolved inorganics (minerals and metals) effectively. Relatively inexpensive initial cost
Disadvantages:
Does not effectively remove bacteria. Beads can trap bacteria and become breeding grounds
Ultraviolet Radiation
Description

Low level ultraviolet light kills bacterial and viral pathogens. The amount of radiation produced is negligible, and it leaves no trace.


A typical UV sterilizer looks like a stainless cylinder with water inlet on one end, and a water outlet on the other. Water passes through a chamber that has a quartz lamp which performs disinfection.
Removes:
Bacteria, Viruses
Advantages:
Sanitizes water
Disadvantages:
Does not remove suspended particles or ions
Distillation
Description

Water is heated to boiling, then cooled to condense the water vapor. Impurities are filtered out by the evaporation, and condensed water is stored and collected in glass-lined container. Distillation is one of the oldest methods of removing contaminants from water, but is seldom used for drinking water, as distilled water has little oxygen and tastes "flat"
Removes:
Bacteria, Lead, Nitrate, Sodium Chloride, Organic Chemicals, Many Pesticides
Advantages:
Removes wide range of contaminants. Reusable
Disadvantages:
Slow process
Requires large amounts of water and energy. May concentrate contaminants with high boiling points
As the chart above makes obvious, there is not a single water purification method that removes ALL contaminants from drinking and tap water. 
Most home purification systems will have a number of the above methods to filter out all possible contaminants before delivering fresh, good-tasting, safe water to the tap for cooking and drinking.
