Water Efficiency – Water Used in Generating US Electricity
In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.
You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.
You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.
Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.
Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.
For a simple reason. It takes a lot of water to produce electricity.
How much? 5% of all US water? 10%? Can’t be as high as 25%?
Electricity and water?
I thought the issue was fossil fuels and greenhouse gases
The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.
Their grand total: 408 billion gallons per day withdrawn for all uses.
The number 1 spot, weighing in at 48%, was thermoelectric power.
Irrigation earned the runner-up prize at 34%.
The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.
How much water is used in generating electricity?
Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.
Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.
According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.
The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.
Nationally:
- Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
- Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
- Geothermal power plants add another 2 billion or so gallons a day.
- Most renewable energy technologies require little or no water for cooling.
These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.
Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.
How much is 3 billion gallons per day?
The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.
Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.
How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.
Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.
48% of all water use: We’re Number One!
How much is 195 billion gallons per day?
Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.
How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.
So, let’s get a higher-level view to help us.
Lake Erie holds 116 cubic miles of water.
Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.
We drain Lake Erie every 22 months.
But the water used is returned to its source.
So what’s the issue about water use?
Power generation returns 98% of the water back to its source (bay, lake, river, ocean).
It’s the environmental consequences.
The Pace Energy and Climate Center explains it neatly:
Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.
Examples include:
- The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
- At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
- The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)
The diversion of water out of the river removes water for healthy in-stream ecosystems:
- Stretches below dams are often completely de-watered.
- Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
- A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
- By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
- The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
- This often eliminates native populations of fish and other wildlife.
- Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
- As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.

Back to those compact fluorescent lamps and LEDs
PowerScorecard.org explains the solution:
By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.
They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.
In short, reduce your use of electricity.

Do We Want Too Much?
What can be done about this increasingly worrying contribution to global warming?
The most important options to reduce aircraft CO2 emissions are:
Changes in aircraft and engine technology; use of alternative fuels, such as (sustainably produced) biofuels; regulatory and operational measures such as improvements in air traffic management; economic measures such as inclusion of aircraft emissions in emission trading schemes.
But, as Giovanni Bisignani, manager of International Air Transport Association (IATA), stated: “Emissions trading schemes only make sense with efficient infrastructure. The IPCC estimates that there is 12% inefficiency in air traffic management globally: we produce up to 73 million tonnes of carbon emissions each year by aircraft flying inefficiently due to air traffic management limitations”. **
On a personal level we could ask ourselves especially in the developed world: “Do we really need to fly so frequently?” The use of telework, teleconference and video conference could be largely increased to plan work and meetings. Can’t the development of land and air transportation infrastructures be balanced better according to the real needs of people and businesses? Trains could connect cities better and more cheaply for example in Europe, where the prices are not competitive with those of many flights anymore (and night train services have been reduced if not cancelled).
Life styles do matter because if millions of people want to have cheap weekends in relatively close tourist locations, many flights are needed to satisfy their desires and consequently a lot of pollution is generated. Also, our per capita emissions could be cut also by reducing the “surplus” trips, by slowing down our life rhythms and enjoying more local attractions in our free time. Who knows? We could discover the “exotic” in our own neighborhoods without flying to the Caribbean Sea…
Furthermore the relationship between the costs and the environmental externalities (i.e. costs not included in the economy like health damages caused by pollution) needs to be considered as well: there are higher marginal impacts for short-distance flights that should be considered in prices paid by passengers.
All these political, technological and personal choices are some of the good examples needed by the developing countries to follow the 21st century’s Western society along a new sustainable path which looks like the only good alternative forward.

Water’s Role in Global Warming
Last week, we introduced you to the Resource Matrix, which is everywhere, it is all around us. It is the world that has been pulled over your eyes to blind you from the truth.
We showed you how economics leads to people maximizing their benefits in “win-lose” propositions: you want diamonds and gold for nothing and they want to give you useless junk for a king’s ransom. And how we’ve been hypnotized in believing what they want is also what we want.
But the scales have been falling from our eyes, we’re beginning to see the truth, and the power has been shifting away from the “I want your goodies for nothing” crowd:
- Do-gooders have increased our awareness and worked to change deals from “win-lose” to “win-win”
- There is no “free lunch:” finite energy resources will run out; actions have consequences, and the consequences of our actions are already visible, rather scary, and quite irreversible; and that the “I want your goodies for nothing” crowd hasn’t been telling the truth
We now realize we’re all in this together: we have greater awareness of our actions and the desire to change, and have ways to change.
Hallelujah and Praise the Collective!
Today, we introduce the resource called water, its parallels with fossil fuels, and its role in global warming.
None of this is to dismiss or diminish the contribution of fossil fuels in global warming. Hey, just like the Special Olympics, if you participate, you get a medal. We just think that gold-medal winner Fossil Fuels has stolen the spotlight, letting silver-medalist Water Use keep us hypnotized in believing that water is a free lunch, and that nature will clear up polluted waters while getting away with breaking the rules.
Water, water, everywhere,
not a drop to drink.
According to our friends at How Stuff Works, who I wrote about sarcastically for their oxymoronic clean coal article in discussing how true public relations stuff really works, gives us this data:
- 98% of the planet’s water is in the oceans. It’s salt water – we can’t drink it or irrigate our crops with it.
- 2% is usable. Of that 2%:
- 80% is locked up in polar ice caps and glaciers
- 18% is underground in aquifers and wells
- 1.8% is in lakes and rivers
- 0.2% is elsewhere: either floating in the air as clouds and water vapor, locked up in plants and animals (and your body), and in foods and beverages.
Okay, so 20% of the usable water (only 0.4% of all water on Earth) is accessible, right?
Well . . . no. Many of the aquifers, wells, lakes, and rivers have been sucked dry like a once-juicy fly carcass in a spider’s web. (The 18% and 1.8% you see above is like the money in the Social Security Fund: there actually is nothing there.)
And many of those water sources that do still have a drop to drink are worse than the ocean’s salt water. Drink salt water and you’ll need to yawn into a bucket. Drink this water and you’ll kick the bucket.
And I know you aren’t asking this burning question:
“So . . . global warming to release fresh water from ice caps and glaciers is a good thing, no?”
Percentage this, percentage that.
Talk my language, will you?
I know I’m pulling the disgusting old government trick: drowning you in an ocean of water statistics.
So let’s make it plain and simple:
You bring in $10,000 a month. You’re also living high on the hog and doing your personal best to outshine every bling-bling Hip Hopster Musical Artist in materially conspicuous consumption:
- $9800 goes to the McMansion mortgage and gold-plated Rolls Royce lease
- $160.00 goes to investments in clothing and accessories
- $0.40 has been lost in the sofa cushions
- $39.60 a month is for everything else: food, phone and electric bills, income taxes, and all the other non-essentials: Don’t spend it all in one place!
Aquifers and wells and lakes and rivers:
Dry or polluted, oh my!
Fred Pearce, author of When the Rivers Run Dry, helps us quickly understand it:
We can all save water in the home. But as laudable as it is to take a shower rather than a bath and turn off the faucet while brushing our teeth, we shouldn’t get hold of the idea that regular domestic water use is what is really emptying the world’s rivers. Manufacturing goods … consumes a certain amount, but that’s not the real story either. It is only when we add in the water needed to grow what we eat and drink that the numbers really begin to soar. (emphasis mine.) (Fred Pearce, When the Rivers Run Dry, Boston: Beacon Press, 2006. p 3)
Here are a few numbers he gives:
- to grow a pound of rice: 250 to 650 gallons of water
- to grow a pound of wheat: 130 gallons
- to produce a quart of milk: 500 to 1000 gallons
- to produce a pound of cheese: 650 gallons
- to produce a 1/4 pound of burger: 3000 gallons
He kindly puts water use into perspective in annual terms:
- 1 ton (265 gallons) for drinking
- 50 to 100 tons (13,250 to 26,500 gallons) around the house
- 1500 to 2000 tons (397,500 to 530,000 gallons) for food and clothing

How Many Gallons to Produce One Pound of Beef?
Lies, damned lies, and statistics
US Beef industry’s Cattlemen’s Association: 441 gallons
Fred Pearce: 12,000 gallons
Water Footprint Network: 1854 gallons (calculations: 15500 litres of water per kg; 4079 gallons per kg; 1854 gallons per pound)
In an industrial beef production system, it takes an average three years before the animal is slaughtered to produce about 200 kg of boneless beef.
The animal consumes nearly 1300 kg of grains (wheat, oats, barley, corn, dry peas, soybean meal and other small grains), 7200 kg of roughages (pasture, dry hay, silage and other roughages), 24 cubic meter of water for drinking and 7 cubic meter of water for servicing.
This means that to produce one kilogram of boneless beef, we use about 6.5 kg of grain, 36 kg of roughages, and 155 litres of water (only for drinking and servicing).
Producing the volume of feed requires about 15300 litres of water on average.
—————————————–
Where does all that water come from?
From virtually everywhere
If it comes from imported goods (Thai rice or Egyptian cotton), the water comes from those countries.
When the water is collected from rivers or pumped from underground, as it is in much of the world, it’s:
- increasingly expensive
- increasingly likely to deprive someone of water (nothing to drink)
- increasingly likely to empty rivers and underground water reserves
And when the rivers are running low, as they are more frequently, there is less water to grow anything at all.
The water used in growing and producing goods around the world is known as “virtual water” and the trade of these goods is known as “virtual water transfers.”
And who’s the biggest water exporting Mouseketeer of them all? The United States.
When you drink coffee from Central America, you are influencing the hydrology of the region, virtually taking a share of the Costa Rican rains. The same is true within a national and regional boundaries. The Colorado River is drained so Californians can eat their Big Macs and have friends over for a Sunday afternoon barbecue.
In the same way that your use of fossil fuel is measured as a “carbon footprint,” your water use, actual and through virtual water transfer, is measured as a “water footprint.”
How big is my water footprint?
I’ll show you mine if you show me yours
Arjen Y. Hoekstra, professor at the University of Twente, the Netherlands, introduced the water-footprint concept in 2002. It “shows water use related to consumption within a nation, while the traditional indicator shows water use in relation to production within a nation.” (Hoekstra and Chapagain, Globalization of Water, Malden: Blackwell Publishing, 2008, p. 3)
With Hoekstra and Chapagain’s water footprint calculator (waterfootprint.org), you select your country, input food, domestic water use, and industrial goods consumption, press a button, and you get your:
- total water footprint for the year
- bar charts for the three components
- bar charts for individual food categories
For example, you’re in the US, eat only 1 pound of cereal a week (.4545 kg) and have a low-fat, low-sugar diet, use a low-flow showerhead, use a no-flush eco-toilet, and never run the tap while brushing your teeth. Two extremes:
- You’re the hippiest of the hip: making $10,000 a year: Your water footprint: 245 cubic meters (65,170 gallons)
- You’re the hippiest of the Yuppies: making $120,000: Your water footprint: 2979 cubic meters (792,414 gallons). Difference due to your income’s effect on industrial production.
Three notes on the calculations, because Professor Hoekstra is European and lives in the social welfare country that started birthing hippies in Amsterdam decades before they showed up in the US at Woodstock:
- You input kilograms for food:
- 1 kilogram = 2.2 pounds = 35.2 ounces
- 1 ounce = 0.028 kilograms. 1 pound = 0.454545 kilograms
- Your water footprint is in cubic meters per year:
- 1 cubic meter = 35.3 cubic feet = 266 gallons
- The higher your income, the greater your water footprint, even if you don’t personally consume anything: you’re a capitalist pig supporting the Establishment Regime, I guess
So how is Cinnamon’s capitalist water footprint? Answer: 650 cubic meters (172,900 gallons)
I showed you mine. Now you show me yours:
Get the naked truth: Calculate your waterfootprint now:
Water’s running out:
I get the fossil fuel analogy so far.
And what about climate change?
We return to Fred Pearce’s book to find an example, of which he has oceans:
China’s Yellow River: The fifth longest in the world, it begins high in the mountains of eastern Tibet and journeys more than 3000 miles. Almost half a billion people depend on it for drinking and crop irrigation, and it’s made China the world’s largest wheat producer and second largest corn producer. Yet more than half of the lakes it feeds have disappeared over the last 20 years, and a third of pastures have turned to desert. This desertification generates huge dust storms that choke lungs in Beijing, close schools in Koreas, dust cars in Japan, and rain dust on mountains across the Pacific and Western Canada.
State irrigation projects along the Yellow River soak up the majority of its water – the total official allocations are greater than the actual flow.
The resulting drought could be an early warning sign of global warming.
Much of the declines in moisture reaching rivers is in line with prediction of climate researchers. So how does this global warming happen?
Higher air temperatures from desertification increase evaporation from oceans and intensify the water cycle. This increases atmospheric water vapor – 8 to 10% more than today. This increases global rainfall, but the rain is being redistributed: middle latitudes (read: the US) are becoming drier. Higher temperatures increase evaporation on land, meaning soil dries out faster, meaning less rainfall is reaching rivers.
The higher temperatures melt glaciers and snowpacks. At first, this leads to unpredecented floods. After the glaciers disappear, meltwaters that feed rivers disappear. The combined decreasing rainfall and increasing evaporation will lower moisture by 40% in the southern and western states.
The Sierra Nevada snowpack could diminish by 70 to 80 percent over the next 50 years. And some of the world’s most productive agricultural regions could dry up.
Global climate is becoming more extreme: the dry areas become drier, and the wet areas become wetter. And more areas are becoming dry deserts. Loss of habitat and agricultural lands. It’s a vicious cycle.
So what can you do?
Navigating through the Resource Matrix
As Fred Pearce points out, your drinking and bathing account for 0.05% of your total water consumption. Your food and clothing weigh in at 95.00%, although I find his 12,000 gallons needed to produce a pound of burger rather wild.
As Professor Arjen Y. Joekstra shows with his Water Footprint Calculator, your consumption of meats accounts for a lot, as does your guilt by association of being in an industrialized country.
The obvious solution: eat fewer e-coli burgers from your neighborhood Salt and Fat Slop Bucket restaurant.
The wiser solution: like your choices in energy use, become more aware of the resources needed to produce anything and the consequences. Such as luxurious cotton grown in the Egyptian desert.

Too Expensive to Be Green?
Really? Seriously? Is it still too expensive to be green? I am a little surprised when people say that cannot do anything to be green because the products are too expensive. This may have been the case eons ago but not anymore. People now say going green is too expensive as an excuse in my opinion. Granted, I am not able to afford solar panels on my roof just yet but that does not mean I am not green or trying to be green in my own ways.
Here are some simple things that you can do now to start you off in the right direction without too much money out of pocket. Keep in mind, that while you will spend money at first, the payback is well worth it for you and the environment.
One of the first things I did to start my own green movement at home was to buy canvas bags for the grocery store. They were $1.00 each and I bought 10 of them. I always leave them in my car so no matter what store I go to I bring a bag with me. Each time I visit the grocery store I get 5 cents back for each bag that I bring.
So each week when I grocery shop I get 50 cents back. Each week that adds up quickly and before you know it, I have made my $10.00 back and am no longer a slave to the plastic bags. U.S. consumers use approximately 100 billion plastic bags annually which require an estimated 12 million barrels to produce! Just think, the majority of these bags are used just once from for less than 30 minutes and then they go into our landfills or end up in our oceans where they are a serious threat to wildlife.
The second green thing I did was change my water bottle habits. I have to admit, this one was hard for me until I did the math and it was at that moment I went to Target to buy a water filter and ordered my CamelBak Better Bottle.
The funny thing is that people are so quick to complain about the cost of gas but have you ever complained about the cost of the water bottles at the grocery store? I paid $10.00 for my bottle and $30 for my water filter and I have never once gone back to the store to buy my 12 pack of water for $6.00. And to think, a 12 pack of water bottles was finished in one week or less! I really don’t like when people say they reuse their plastic water bottles…. Do you know the bacteria that are on the bottles and the plastic leaching that occurs? Please do yourself and the environment a favor and buy a BPA Free water bottle today!
How many of us use paper napkins each day for lunch and dinner? Time to save a tree! Even napkins made from recycled materials are not as innocent as they may seem since they too wind up in landfills. A family of 4 can easily go through 84 paper napkins a week and if you think of each paper napkin costing 2 cents – well that adds up quickly over the course of a week, month, and a year. Cloth napkins can be used several times before tossing them into the laundry. With a family of four, laundry is done quite a bit so go ahead and make the switch.
Finally, do you wash all loads of laundry in cold water? Did you know that if you washed all of your clothes in cold water your clothes would last longer? Not only that, but you would save on your electrical bill. Unless you are washing baby diapers or grease stains, cold water is the way to go. 85-90 percent of the energy needed to wash your clothes in a machine is used to warm the water. Only 10-15 percent actually goes into the washer. The next time you need to buy laundry detergent, look for the detergents that are specially made for cold water.
And of course, we all know about the light bulbs and such but these were a couple other reminders of what you can do today to start saving money and you can be proud of yourself for going green! Remember, it is cool to be green!

CO2 Footprint of a Product
We’ve certainly seen quite a few companies come out and say that their manufacturing facilities have a zero impact on the environment, meaning zero footprint, but indeed, there is much controversy on how to determine what a zero foot print is. It’s almost impossible to get to zero, even if a company goes and plants 10,000 trees over the course of 5-years.
The other day at a Think Tank meeting, we were talking about how to establish a complete CO2 discharge chain of a product, including all its components in the process of making it. From the wrappers, card board box, printing, assembly, energy to do all that, the distance the people traveled to work in what type of cars, etc. I mean really narrowing down the actual discharges.
Not because we are Global Warming alarmists, but because we feel it is not exactly correct for a company to claim Zero Emissions. And that we must have a more realistic view of the total process, Supply chain and all.
Many companies like Dell in Texas have stated that they have finally achieved zero emissions, but they were attacked for stating that, why? Because, everyone has a different concept of what nothing is. In other words we are all out there fighting over nothing and that makes no sense to anyone, no matter how you figure it.
Indeed, we should be applauding Dell for their solar panels, LEEDs certified warehouses and assembly plant and all their hard work and meaningful dedication to do the right thing. And yet, we are not doing that are we? Instead we find people attacking businesses, even those that go out of their way, spending millions of dollars to do the right thing. I ask are we doing the right thing by allowing persnickety environmental complainers to attack America’s greatest companies?

Go Green – Get Rid of Junk Mail
Four million tons of junk mail is sent every year…at least half of which is never even opened. You probably are aware that your name, address, and spending habits are regularly being traded and sold on the open market. By investing half an hour now, you can rid yourself of most of the junk mail for up to five years…and save a few trees while you’re doing it.
So here are a few tips that you can work on to lessen the load of junk you get every day:
- Product warranty cards do not register your product…that was done when you purchased it. They are used to fin out about your interests and your income for the sole purpose of junk mail.
- When ordering something on the phone, tell them specifically to not give your name and address to other companies for any reason.
- Any time you donate money or order a product or service by mail, write on it in large letters, telling them not to sell your name and address.
- When the junk come by first class mail, cross out the address and bar code, circle the first class postage and write “refused: return to sender”.
- Your credit card companies are the worst offenders and probably sell your name and address more than anyone else. Stopping them is easy; you just need your address and social security number. One call does it all for agencies Equifax, Trans Union, Experian and Innovis. Dial 1-888-5 OPT OUT (or 1-888-567-8688) 24 hours a day.

Can You Be Legal, Clean, and Green?
You may have seen something on the news about Spokane, Washington where there is now a ban on dishwasher detergent made with phosphates. While this may seem to be an isolated case, there are actually several states (including the rest of the state of Washington) that will make dishwashing soap made with phosphates above a very small level illegal in 2010.
What is phosphate anyway and why is it used in dish washing soap? Phosphate is an inorganic chemical that is a combination of salt and phosphoric acid. Because it can clean things like hard water stains, and grease, phosphates are used in all kinds of things including dish washing soap.
Why all the fuss? Phosphate is a problem when it finds its way to freshwater rivers and lakes. The phosphate encouraged the growth of algae which depletes the oxygen in these rivers and lakes, killing off fish and other wildlife.
While there are green alternatives out there, deleting the phosphates from the dish washing soap can leave one unsatisfied with the resulting product-and a lot of dirty dishes. Plus some of these green alternatives are pricier than their cheaper phosphorous counterparts. This has caused people to travel outside their state to obtain contraband detergent from other states-which, of course, defeats the purpose of the bank in the first place.
What should you look for in a green dish washing soap? Are there green products that work as well? While there is no direct substitute for phosphorous, but there are other substances that can be used. How well they will work depends on a number of factors, perhaps the most important being the hardness of the water used for cleaning.
One ingredient that be used is a surfactants. Surfactants are usually biodegradable and are used to provide cleaning power and increase the ability of the water to separate the soil from the dish. Anionic surfactants work well as detergents, but can be less than effective in hard water. Amphoteric surfactants are used for their foaming power and can often be found with anionic surfactants. There are other substitutes for phosphates, but these can be even more dangerous than the phosphates. They include nitrilotriacatic acid (NTA) and caustic alkaline chemicals (which are particularly dangerous when ingested-as sometimes happens with children).
It may take some trial and error to come up with the phosphate substitute that works best in your water. It is unlikely that the ban on phosphates is going away, so it is better to start exploring the options now. In the meantime, the soap manufacturers continue work on the perfect phosphate substitute, but there are some excellent alternatives out there.

How to Keep the Environment Clean
If you want to keep the environment clean then you need to recycle everything you can. You should set aside a few spaces so that you can keep your recyclables in a separate area. All of your water bottles should go into one container so that it will make it easier for you to take them to the recycling center. Also you need to make sure that you recycle all of your chance and glass bottles as well because this will also help the environment. Many people do not know that you can also recycle your old newspaper, you can call to have it picked up each month.
If we are going to prevent global warming than one way that you can take part is to recycle everything you use. the best thing you can do is educate yourself on the best way that you can recycle all of your throwaway items. Maybe some of your old clothes can be donated to Goodwill this way they can be recycled and used again. Make sure that you try to avoid using plastic bags from the grocery store because once they end up in a landfill they can cause a lot of problems. Once you have started a recycle program in your house you will find that it is easy to do.
Remember that if you want to improve the environment you need to recycle everything you can. It always works better if you have specific containers that you use for each of your recyclable items. Once you make a few small steps towards improving the environment you will feel better about yourself.

A Modern-Day “Roman” Aqueduct For Florida
The west coast of Florida remains trapped in an ongoing drought. In Pinellas and Hillsborough Counties (Tampa and St. Petersburg/Clearwater) severe restrictions on water use are in place. Even the use of reclaimed water for lawns and gardens is now restricted. The rainy season is not yet here; but in past years the amount of rainfall received during the wet months was far below the historical average, so that reservoirs and ground water supplies have never had a chance to recover.
The situation is quite different in northern Florida, in the Panhandle and all across the State close to the Georgia border. The weather in those parts of the State is generally wetter, and more consistently so, than the weather farther south.
Yesterday, our local St. Petersburg Times carried a story (with photographs) of the damage which is now being inflicted in Madison County (which borders Georgia) by floodwaters from the Withlacoochee and Suwannee Rivers. The storms which produced the rain moved from west to east across the Panhandle over the past week, to the point at which the Withlacoochee crested at 89 feet, four feet above the record set in 1948. So far, the rising floodwaters have destroyed or caused severe damage to almost 200 homes and lesser damage to 500 more, all areas combined. Two people are known dead, and one person is missing.
Quite apart from the possibility of reducing the tally of deaths, personal injury, and property damage which even a partial remedy for river flooding in these areas might entail, it boggles the mind just to consider the sheer waste of so much fresh water. Most of that damaging flood water will be gone forever as it eventually finds its way to the Gulf of Mexico. That’s a shame, because so much of it could be put to good use in the west coast, central, and other parts of the State where it is so desperately needed. The waste is not just limited to damaging flood waters, either. The “top of Florida” is blessed with more rainfall, on average, than it needs. Obviously, the flow of river water into the Gulf represents a volume of water which has not been put to good use.
In passing, we acknowledge that the flow of a certain amount of river water into the Gulf is said to be necessary for the health of the shellfish beds near the coastline.
Even so, it seems inadmissible to stand by and do nothing but watch a surfeit of water in the northern counties lay waste and then go to waste while there is such a great need for water in other areas of the State. Surely there is a partial remedy which might ameliorate the problems in the affected sections.
The Romans found a way to move big volumes of water over considerable distances. Surely we can build on their success – and on successes over the centuries since that time – by constructing an Aqueduct system to bring excess water from the northern Florida counties to drier areas to the south.
The best part is that the right-of-way is already in place! It’s called Interstate 10 and Interstate 75. Take a peek at a map of Florida. Find the intersection of I-10 and I-75. The Suwannee and Withlacoochee Rivers are close by, as are other rivers. There are others to the west, and I-10 probably crosses every one of them.
Excess water could be fed into the Aqueduct lying above-ground or underground in the median of I-10 at various points along its route, and then fed south toward Tampa and St. Petersburg/Clearwater in that part of the Aqueduct lying within the median of I-75 and I-275. Do you see how obvious that is?
If ever there was a perfectly-planned right-of-way for a particular purpose, although not part of the design at the outset, this is it.
There would be hurdles. There always are. Will and determination were invented for the purpose of overcoming hurdles.
It seems to me that the construction and operation of The Florida Aqueduct is an undertaking which private capital should undertake. It need not cost the State a penny.
Let’s see whether anyone steps up to the plate.
