A Good Rain Pours 100 Rose Bowl Stadiums’ Worth of Nasty Water into Santa Monica Bay

 

Editor’s Note.  The piece below is excerpted from an LA Times article by Mathew King, who is communications director for Heal the Bay, a Los Angeles environmental group founded in 1985 to stop the dumping of raw sewage into Santa Monica Bay.

Even if you’re not a surfer, you have reason to be concerned about polluted storm water. Rimmed by foothills and mountains, Los Angeles County is like a giant bowl tilted toward the sea. When it rains, water rushes along paved streets, picking up trash, fertilizer, pet waste and automotive fluids before heading to the ocean via the region’s extensive storm drain system. A single typical day of rainfall spews an estimated 10 billion gallons of runoff into Santa Monica Bay, untreated and unchecked. That’s the equivalent of roughly 100 Rose Bowl stadiums’worth of dirty water. It’s little wonder the county claims seven of the 10 most polluted beaches in the state.

This is not simply a public health issue; it’s also a huge waste of a precious resource. Los Angeles imports costly and increasingly scarce water from Northern California and the Colorado River. Storm water — if held, filtered and cleansed naturally in groundwater basins — could provide a safe, more secure and less costly source of drinking water.

The county now has a chance to address the problem. This month, notices have gone out to county property owners about a proposed storm water fee. Most single-family residential parcels would be assessed $54 per year, and the money — about $270 million annually — would be used for innovative infrastructure projects to capture and reuse storm water. On Jan. 15, the county Board of Supervisors will hold a hearing on the issue, after which an election by mail is likely.

“A single storm can sweep billions of gallons of polluted runoff directly into Santa Monica Bay. Contact with this bacteria-laden storm water can lead to a variety of unpleasant ailments, from upper-respiratory infections to severe gastroenteritis.”– (Los Angeles Times)

Some opponents are already crying about hidden taxes, but this measure is more rightly viewed as a sound economic investment. Funds raised will enable municipalities to develop multi-benefit wetlands, parks and open spaces that can recharge groundwater supplies, saving money in the long run. Thousands of local jobs in the construction, engineering and landscaping industries will be created. Reclaimed storm water will irrigate neighborhood parks, ball fields and school grounds instead of fouling rivers and beaches.

An advisory committee of property owners and members of the public, appointed by the supervisors, would approve project plans and oversee the funds. Fees could not be raised nor diverted to any other use.

Surfers like me often do dumb things. But Los Angeles County can be smart about storm water. Let’s stop pouring money, and bacteria, down the drain.

Examining California’s Water Footprint

by Rick Paulas

 

Before talking about “water footprint,” it’s probably best to explain it. Whereas water usage is simply the measure of how much of the life-giving liquid people are using on a regular basis (taking a shower, watering the lawn, etc.), water footprint’s a bit more all-encompassing.

Let’s say you’re eating a burger and drinking a glass of water for dinner. Water usage would just take a look at how much water is in that cup. Water footprint, meanwhile, accounts for the liquid, but also figures in how much water it took to create the beef patty, how much water went into making the bun, how much water was used in the cultivation of the lettuce and tomatoes, the ketchup, the mustard, and so on. As such, water footprint paints a much different and more complete picture for how much water everyone actually uses. Which is why this study from the Pacific Institute is getting so much attention. For the first time, we have a comprehensive look at just how much water Californians use on a daily basis. And it’s a lot:

1,500 gallons of water a day.

That’s how much the average resident of California goes through. Read that again.  Fifteen-hundred gallons a day.

While this number isn’t quite out of the norm from the rest of the United States — water footprint is pretty uniform across the country — it well outpaces the rest of the world. “Our water footprint is much larger than the global average,” says Heather Cooley, one of the study’s authors, “in part because we consume more meat and dairy products, and simply because we consume more products. We have more computers, more cell phones, more stuff in our lives. And there’s a water requirement for all of it.”

What’s surprising about the information specifically regarding California, however, is that the state actually brings in more “virtual water” (another phrase for what’s calculated in water footprint) than it sends out. “I had sort of assumed we were a net exporter of water,” says Cooley. “Agriculture is a big part of California’s history, and some of that is exported and feeds the rest of the United States and world. I had assumed that’s where most of our water was going.” But instead, California ends up importing more virtual water than it sends out. Which is where things can start to get scary.

If there’s a drought in the Midwest, or Mexico, or China, it will affect the goods and services that are coming into the state. “We often perceive water management as a local issue,” says Cooley. “We only think about our local community, and whether there’s enough water available to fit our needs. But because of the movement of goods and services, we are more closely linked to water conditions in regions outside of our borders.” Simply having a rainy year locally isn’t enough to satisfy all of our consumption needs anymore. The world has to have a good rainfall.

Which isn’t to say there aren’t positives in the globalization of water consumption. As Cooley points out, by everyone being linked, it reduces the vulnerability of local water supplies. (The flipside to a drought in China now affecting us, is that a drought in California won’t be as disturbing locally as it once was.) Globalization means that water management is no longer a local issue, but a world one.

Meaning, the amount of water we’re each using daily is one hell of a drain on the rest of the world. “Water is an essential ingredient in almost everything we’re using,” says Cooley, “whether it’s to grow a crop or produce a pharmaceutical, all sorts of things require water, and large amounts of it.” And 1,500 gallons a day, per person, is an extraordinary amount of that essential ingredient. So if you’re consciously turning off the faucet while washing dishes, or limiting your time in the shower because you want to conserve, that’s great and everything, but you’re missing the big picture.

“There’s two ways we can reduce our personal water footprint,” says Cooley. “That’s through consuming less in general — cell phones, computer, furniture, all of those things.” But there’s also simple dietary changes a person can make on a daily level to cut down on the water they’re consuming. “Meat and dairy products are generally very water-intensive,” says Cooley, “so on a personal level, we can reduce our water footprint by using less of those things.” In other words, put down that double cheeseburger and pick up some more fruits and vegetables. Not only will you be doing your body a great service, but also you’ll be helping to save the world.

Editor’s Note:  The concept of the “water footprint” isn’t new.  Here’s a website devoted to the topic that has such features as a personal water footprint calculator.

The Fiscal Cliff for Water


Posted December 25th, 2012

Water’s ‘fiscal cliff’ is no pretty waterfall

  by Michael Reuter

Editor’s Note: Michael Reuter serves as director for The Nature Conservancy’s North America Freshwater Program and for the Great Rivers Partnership.

Think the “fiscal cliff” is the worst of our worries? Pour yourself a glass of water. In it you can see the illusion of abundance for most of us in North America.

Just as we raced through the ‘80s and ‘90s with checkbook in hand, all the while amazingly ignorant or unwilling to discuss the makings of a deficit crisis, today we splash around in a wet abyss of ignorance about the health of our water-related infrastructure and the economies that depend on it.

Consider these warning signs:

More than half the states in the U.S., including many of those that are the most agriculturally productive, declared drought disaster in 2012. The vital shipping corridor on the Mississippi River is at risk of shutdown — a system that’s serves a port district that ships more tonnage than any other in the world. It’s anybody’s guess how much that will affect the price of food or a gallon of gas if this continues unabated.

Ironically, the year before, the Mississippi and Missouri rivers experienced record flooding, which devastated crops and communities. The difference in 2011 over 2012 water levels surpassed 60 feet.

Compounding the issue, the Army Corps of Engineers estimates a $60 billion backlog of water infrastructure projects, including needed repairs to dams, levees and the like. Meanwhile, the EPA has estimated the nation will need to invest $334.8 billion between 2007 and 2027 in order to deliver safe drinking water. How much are you willing to pay for a glass of clean water?

Demand for water now exceeds supply on the Colorado River, which provides water and electricity to some 40 million people in fast-growing cities including Phoenix, Las Vegas, Los Angeles, Denver and Salt Lake City. Water levels in Lake Mead and Lake Powell have decreased dramatically. In fact, the river now dries up before it reaches the sea. And scientific projections call for a 20 percent reduction in precipitation in coming years and an 83 percent in increase in population by 2050 in this basin.

Think this won’t affect folks who don’t live in these places? Think again. Water in the Colorado River provides irrigation for nearly one-third of the nation’s winter crops and 13 percent of our livestock.

So is there any chance we could learn a lesson from the fiscal cliff debacle? Better yet, can we see the relationship between these crises? If we did, we would recognize it’s the right time to invest in our natural and built water infrastructure. Some reasons:

Jobs: We need them. Consider the economic impact of the Mississippi River. More than half of the goods and services consumed by Americans are produced with water that flows through this system. It’s an economic engine for many of the 31 states the basin drains.

Water: Our competitive edge. It’s not our labor, our factories or ingenuity alone that makes this nation competitive on a global scale. It’s also our ability to ship goods to and from our ports using more navigable waterways than the rest of the world combined. Our inland and intracoastal waterways directly serve 38 states, moving some $73 billion worth of goods each year.

Prevention: Disasters are costly. We have learned some important lessons about managing floods. In addition to dams and levees, we need to invest in “natural infrastructure” like floodways or floodplains to provide sufficient room for rivers during floods. The return to taxpayers on such investments would be measured in the billions of dollars.

Communities: Quality of life depends on natural systems. Healthy rivers provide a plethora of benefits for people and nature. For example, clean water flows out of our floodplains that act as natural filters, removing excess sediment and nutrients that increase water treatment costs. Where water flow is slowed by nature, it has more time to seep into the ground and can replenish underground water sources (or aquifers), which serve as an important source of water for farmers and communities. These are some of the richest habitats on Earth, drawing outdoor enthusiasts of all sorts and boosting our local and national economies. The Outdoor Industry of America recently released an in-depth study that found outdoor recreation provides 6.1 million jobs and accounts for $646 billion in spending each year.

We shouldn’t ignore this hidden crisis as we dismissed the economic issues that led us toward the fiscal cliff. Similar to mortgage derivatives and other obscure financial instruments, the myriad of human and man-made causes to our water infrastructure crisis are very complicated, but too important to ignore.

To address such issues within the Mississippi River basin, we’ve established America’s Great Watershed Initiative. This is an initiative that brings together leaders from agriculture and industries as well as government, academia and nonprofit organizations to help find common ground about how to make strategic investments in the health of the entire basin for the benefit of people and nature.

On the Mississippi and at great rivers around the world, it will take collaboration, compromise and careful planning to create management approaches that optimize the many uses of our rivers well into the future.

Cold Water Swimming:  It’s More Popular Than You Think

Cold water swimming is a big event in certain parts of the world as a Christmas  or  New Years celebration, but it is also a routine practice of many at any time when the weather and the water are cold.  It is a little-publicized sport, although there are those who keep records about it.  Health benefits are usually associated with the practice, although these have not been verified.

December 23, 2012: People take part in an annual Christmas bath in Warta river, with the outdoor temperature reaching 10 Celsius below zero in Uniejow near Lodz central Poland.

The South London Swimming Club sponsors a very popular event (so popular that online registration for the  upcoming competition has been cancelled because of excessive demand)  called the Cold Water Swimming Championships.   Here is information from the Club’s notice of the upcoming event:

This biennial event has become a must for cold water swimmers, attracting both the experienced cold water swimmer and people who are trying it for the first time. Age and ability is no barrier as, with water temperatures as low as 3°C, jumping in for the 30 yard races is a challenge in itself.

The Cold Water Swimming Championships celebrates the fun and camaraderie of cold water swimming and the competiton is often just friendly but can also be fierce. There are a variety of races this year, from the traditonal “head-up” breaststroke, the freestyle dash and relays to the 450 metre challenge for the really fool hardy. To help the competitors recover there will be a Finnish sauna available after the races as well as good food, a host of stalls and entertainment going on throughout the day.

Here is a taste of the SLSC Cold Water Swimming Championships.

If you’re looking for an event near you, here’s a Wikipedia rundown of some of the main events:

Northern Europe

In Finland, Northern Russia, Norway, Sweden, Denmark, Estonia, Lithuania and Latvia, the cold-water swimming tradition has been connected with the sauna tradition.

Ice swimming on its own is especially popular in Finland. There is an Avantouinti (ice-hole swimming) and the Avantouinti Society.

United Kingdom

Famous locations include the Serpentine Lake in Hyde Park, London.

China

In Harbin, northern China, many ice swim in the Songhua River.

Russia

There are strong traditions for cold-water swimming and dousing with cold water in Russia. They are done for health benefits, as a ritual of the Orthodox Church for the feast of the Baptism of Our Lord, and for sports. Such club members are called “walruses” (Russian: моржи) instead of “polar bears”.

North America

The members of Canadian and American Polar Bear Clubs go outdoor bathing or swimming in the middle of winter. In some areas it is unusual or ceremonial enough to attract press coverage. Polar Bear Swims are conducted as fund-raisers for charity, notably the Special Olympics.

The oldest ice swimming club in the United States is the Coney Island Polar Bear Club of Coney Island, New York, who hold an annual polar plunge on New Year’s Day as well as regular swims every Sunday from November to April.

International Ice Swimming Association

The International Ice Swimming Association was founded by Ram Barkai of South Africa and conducts 600m and 1-mile swims in open bodies of water whose water temperatures are less than 5°C (41°F).

World Winter Swimming Championships

The World Winter Swimming Championships are also held annually in Europe where Extreme swimming events attract hundreds of athletes from dozens of countries.

To end this, here’s a famous cold water swimmer out of his usual element making an underwater delivery in warm water:

Joy to the fishes in the deep blue sea/
And joy to you and me.

 

 

How Temperature, Pressure, and Water Quality Affect How Much Water Your Home RO Unit Makes

If your home reverse osmosis unit is rated for 50 gallons per day production, that means that it will, theoretically,  produce water at the rate of 50 gallons in 24 hours, or about 2 gallons per hour.  What it will actually produce is only remotely related to its advertized production rate.  It could be more, but it is often less.  And it usually doesn’t matter.  Unless you use the unit to fill an aquarium, you probably don’t need more than a couple of gallons per day anyway. As long that water comes out of the faucet when you request it, all is well.

When the membrane makers give the gallons-per-day figure for their membranes, they don’t take into account that the unit will most likely be used on an undersink reverse osmosis unit where it has to fill a pressurized storage tank.  If the unit spends most of its time simply topping off a pressure tank when a pint or two of water has been taken out, its advertized production goes way down.

However, the three main variables that influence the final flow rate of the product water from an RO unit are inlet water pressure, the TDS (total dissolved solids) of the inlet water, and the temperature of the inlet water. With these, the membrane maker makes certain assumptions for residential membranes.  The assumed numbers do not represent ideal conditions or even average conditions;  they are simply numbers that have been agreed upon to provide a standard by which membrane production performance can be measured.  Here are the assumptions:

Inlet Water Pressure: 60 psi.

Inlet Water Temperature: 77 degrees F.

Inlet Water Total Dissolved Solids: 500 ppm.

The following chart shows how each of these affects the actual amount of water that comes from your unit.

Variable  How This Affects Performance Discussion
Water Temperature: 77%. As the temperature goes down, production goes down, sharply. As the temperature goes up, so does production. 77 degrees F. is higher than water temperature in most areas of the country. It, of course, varies considerably by the season, so you might notice that your RO unit makes more water in summer than in winter.  (If your water source is a deep well, the season won’t matter much.)  Note also that as temperature and consequently production goes down, the overall TDS rejection rate of the membrane goes up.  That is, when low temperature causes the unit to produce less water, it actually makes better water.  It isn’t practical to try to control inlet water temperature for residential units other than by a simple fix like adding more tubing to the inlet water line to allow exposure to ambient temperature as the water enters the RO unit. This might speed production up a bit in the winter.
 Inlet Pressure: 60 psi.  As pressure goes up, production goes up; as pressure goes down, production goes down.  60 psi is a fairly common pressure for city water, but most wells run between 30 and 50 psi.  A residential membrane makes little water at 30 psi.  This variable is the easiest to control.  Adding a booster pump in front of the unit will increase inlet pressure to about 80 psi and water production will go up significantly.
 TDS of Inlet Water.  As feedwater TDS goes up, RO production goes down; as feedwater TDS goes down, production goes up.  500 PPM TDS is higher than most city water.  Typical city water that comes from a lake, for example, might be 200 ppm.  Your water is the water your RO unit has to deal with, and there is no practical way to alter its TDS before it enters the RO unit.  (The unit will, of course, make a 90% plus reduction in the TDS coming out.)

 

 

How to Determine the GPD Production of Your Home RO Unit

Expected production for home reverse osmosis units is usually stated in gallons per day (GPD). Many factors affect the production. These include inlet water pressure, water temperature, total dissolved solids (TDS), the condition of prefilters, etc.

Here’s an easy way to determine the actual production of your RO. The only tools needed are a standard household measuring cup (or any measuring device that has a milliliter, or ml, scale) and a watch or clock with a second hand.

1. For undersink units, turn off the valve at the top of the tank to isolate the tank from the system, then lock the dispensing faucet open and let the unit produce into the sink for a minute or so. The drip or small stream you see is the actual production of the unit—how fast it is making water. (For countertop units, just start the unit and let it produce water for four or five minutes until a steady production rate is established.)

2. Using the watch and measuring cup, get an accurate measure of how much water the unit produces in milliliters into the cup in one minute.

3. Multiply the result by 0.38 to convert milliliters per minute to gallons per day. The result is how many gallons your reverse osmosis unit will produce if it runs for 24 hours.

Example: If your unit is making 50 milliliters per minutes, multiply 50 X 0.38. The result is 19. Your unit is producing water at the rate of 19 gallons per day.

The Oil Company Did Not Apologize For the Massive Leak.   It Just Said,  “Oops.”

A water spill estimated at 1.8 million gallons occurred in December 2012 in rural El Paso County east of Colorado Springs. Two massive above-ground freshwater storage tanks failed.

The water was to be used as part of the hydraulic fracturing process.  An oil company representative assured that that no fracking chemicals or salts had yet been added to the water, but declined to reveal the source of the water.

The water broke through the walls of storage tanks. There was no further explanation for the release.

It is hard to imagine a “leak” of 1.8 million gallons of water.  The weight of the water is some 14,000,000 pounds.   A typical fracking operation consumes that much doubled, at least, and usually more.  This leak alone would furnish water for 27 homes for 2 years.

One authority questioned the company’s ability to protect ground water from fracking fluids during ultra high pressure underground injection when it apparently cannot control plain water on the surface.

The Main Source of Mercury Ingested by Humans Is Tuna

According to an extensive new report called “Sources to Seafood: Mercury Pollution in the Marine Environment,” mercury pollution near the ocean’s surface has more than doubled as a result of human activities over the last century.

That mercury is largely invisible, but it becomes a human problem when it enters our bodies when we eat seafood.  It is especially harmful to babies born to women exposed to mercury, causing cognitive or developmental problems.

As the chart illustrates, tuna is by far the most largest contributor to mercury poisoning in humans.    Americans get most of their mercury from tuna, largely because it is the most affordable option.

Where Does The Mercury In the Ocean Come From?

By far the greatest part of the mercury that goes into the open ocean is from atmospheric emissions, which comes from fossil fuel burning. Coal-fired power plants are the biggest source, globally.  Also,  on coastal areas like Maine, the Gulf of Mexico, and San Francisco Bay, much of the contamination comes from industrial sources, especially mining operations. As for regions of origin of mercury in the seas, the U.S. is not the largest contributor of atmosphere mercury.  Asia as a continent now far exceeds North America and Europe in mercury pollution.

Fortunately, if mercury emissions can be brought under control, mercury content of fish should go down accordingly.

Fluoridation of Water Supplies Is Recommended by Dentists, Therefore It Must Be Safe

by Hardly Waite

One of the most frequently used reasons given by proponents  adding fluoride to drinking water is that fluoride has been used for over half a century and it must, therefore, be safe. Another favorite argument is that fluoridation is endorsed by government “experts” and dental professionals, so it must be safe.

If we followed this logic–that long use and recommendation by experts makes things right–we would still be smoking cigarettes to improve our health, as the American Medical Association for some time recommended;  mothers would still be advised to get their infants on formula as soon as possible,  because (according to the AMA in the 1950s) breast milk is not adequate nutrition for babies; we could forget worries about dentists putting poisonous mercury fillings into our mouths (they have, after all, been doing it for 150 years, so it must be safe); we would still be driving cars with gasoline that spews lead into the environment; the water pipes to our homes would be lined with asbestos, since that was the piping  recommended by experts for decades; our children would be playing in the white spray emitted by DDT trucks spraying for mosquitoes, which experts once told us was absolutely safe; and,  doctors would still be applying their favorite treatment, draining out blood, for virtually anything that ailed us, for the world’s leading medical experts did just that for some 2500 years.

Bloodletting was still going strong at the time of this 1860 image. It was widely practiced in the 5th century BC, and it was the main treatment strategy at the time our first president George Washington was bled to death by the best medical minds of the time. Shouldn’t a treatment 2500 years old and praised by the greatest physicians throughout the ages be used today?

There may be good reasons why fluoride should be added to public water supplies,  but the recommendation of dentists and decades of fluoridation are not among them.

 

Some 94,000 Toys Sold in the US Are Life-Threatening

A recall was announced in mid-December 2012 of water-absorbing toys which the U.S Products Safety Commission says can cause death to children.  The toys grow to 400 times their original size in water.  When swallowed they can cause vomiting, dehydration and even death.

Since the toys do not show up on an x-ray,  surgical removal may be required. An 8-month-old Texas girl who swallowed a toy required an operation.

The recalled toys include Water Balz, Growing Skulls, H2O Orbs from the movie “Despicable Me” and Fabulous Flowers.  Over 94,000 toys were sold in the U.S.

Some of the retailers and websites who sold the expandable toys are:

Bed Bath & Beyond, Five Below, Hobby Lobby, Lakeshore Learning Materials, Microcenter, Urban Outfitters Direct and Wegmans, Amazon.comincrediblescience.comkeyporthobbies.comamericantoystores.com,  and  Universal Studios.

Reverse Osmosis Tanks Can Be Sanitized Without Special Tools

 

Sanitizing the storage tank of small, undersink reverse osmosis units doesn’t have to be a high tech procedure.  It is simply a matter of getting some common household bleach into the tank and giving it a little time to work. To do this procedure, you’ll need some standard household bleach and an eyedropper.

1. Turn off the inlet water to the RO unit, lock the ledge faucet open,  and allow all the water to run from the storage tank.

2. When no water is coming from the faucet, turn off the valve at the top of the storage tank and remove the tube from the tee that connects the tank to the RO unit.  (Not from the tank end, but the other end of the tube.)

3. Shake as much water as you can from the tube and use an eyedropper to drop as much bleach as you can into the empty tube.  A few drops is plenty.  Careful–bleach can be messy and it can discolor items that it falls on.

4. Reconnect the tube to the tee, being careful not to allow the bleach to run from the tube.

5. Close the ledge faucet, open the tank valve, and turn on the inlet water to the RO unit. Allow the RO unit to fill the tank. This will take at least a couple of hours. As the tank fills, the bleach is swept into the tank.

6. Do not use the water for at least 3 hours after the tank is full.  Letting it sit overnight is best.

7. After you have given the bleach sufficient time to work, start using the unit.  You do not need to drain the tank.  The unit’s post filter will remove the bleach from the water.

Note that this procedure sanitizes the storage tank only.  Sanitizing other parts of the unit is a more complicated issue.
