For the third year in a row, Bakersfield, California ranks as the nation’s second smoggiest city in America. Coming in just behind Los Angeles, Bakersfield is also the second most ozone-polluted cities.

But, that’s not all. Bakersfield has now moved into first place as the city with the most fine particulate pollution. According to an annual American Lung Association (ALA) report, which ranks America’s cities with the unhealthiest air, Bakersfield was third behind Pittsburgh and Los Angeles last year.

The ALA reports that, while America’s air has gotten somewhat better over the last 10 years, many cities still suffer from severe air pollution problems. In fact, despite progress in cutting air pollutants and a booming “green” movement, almost every major metropolitan area is fraught with considerable air pollution.

The ALA rates cities on three primary criteria: ozone, short-term particle spikes and long-term particle averages. Each group of ratings is based on statistics collected from the years 2005 through 2007 at monitoring stations maintained by the United States Environmental Protection Agency (EPA). Los Angeles, Fresno and Bakersfield, all in California, had the dubious distinction of being on the top 10 list of all three categories.

Air pollution has become a major threat to human health. This is especially evident when you consider that roughly 60 percent of Americans are currently breathing air dirty enough to send people to emergency rooms across the country, to shape how children’s lungs develop and to kill through the development of serious respiratory illnesses.

The ALA’s annual report states that of the 25 cities with the worst ozone pollution problems, 16 recorded higher ozone levels when compared with last year. A dozen of the 25 cities with the worst average particle problems, which include microscopic soot, diesel exhaust, various chemicals, metals and aerosols, experienced a spike in these pollutants.

Another four cities showed no change and, thankfully, nine cities actually showed some improvement. And, of the 25 worst, 13 cities recorded more days of severe spikes in particle pollution than they had last year.

But, what contributes to the pollution problems in these 25 cities with the worst air pollution? Let’s look at Bakersfield.

It has been over a decade since the first reports of the growing air pollution that is still threatening the United State’s most diverse and productive farm counties in California’s Central Valley. The reasons for the advances in air pollution are manifold and include mist from fertilizers and pesticides and dust from tractors that help grow half of our nation’s produce.

However, other factors also contribute to the rising air pollution. The meteorological conditions and topography of the region only make matters worse, and they also make the problem very difficult to solve.

Bakersfield is boxed in on three sides by mountains. Inversion layers, which act as a lid on the air and hold the pollution close to the ground, are present in both winter and summer. There is little or no wind to take the pollution elsewhere, so it just sits over the city.

Bakersfield’s Kern County also ranks as the worst county in average annual particulate pollution. However, some efforts to reduce the toxic air pollution have been made.

According to the San Joaquin Valley Air Pollution Control District, the county has been able to reduce stationary sources of pollution by 80 percent since 1980. This has been accomplished through various measures, including regulations on oil processing and, in 2003, restrictions on wood-fueled fires. Additional farming regulations, which reduce the number of harvesting machines as well as the number of trips made through the fields, have also helped.

Despite these accomplishments, county officials now say they need state and federal assistance in controlling the heavy-duty trucks that pass through on Interstate 5 and Highway 99. These semi-trucks, cut east to west hauling produce from farms to packaging facilities, fall outside the county’s regulatory authority.

To date, air pollution controls have cost Kern County businesses approximately $40 billion. This $40 billion is split between to important plans – one aimed at reducing particulate matter by 2015 and another plan aimed at reducing ozone by 2023.

However, the financial cost of noncompliance with federal pollution standards may be much more. Being out of compliance with federal Environment Protection Agency standards costs Kern County $2 billion in forfeited federal highway funding and puts a dent in its ability to attract more businesses to the area.

There are other intangible costs that are just as important as the strictly financial costs. The ALA emphasizes the poor and deteriorating lung capacities of the young people who are growing up in such dirty, polluted environments. A University of California Fullerton Study estimated the economic cost of not meeting EPA air standards for the southern California region, which includes all of Los Angeles, at $6 billion per year in health-related costs as well as premature deaths.

So, while it does require huge amounts of money to clean up the air, massive amounts of money are already being paid out for the declining health of young people, increased medication usage, and shortened lives. The ALA is working with local governments and promoting partnerships between the county, state and federal authorities, but much more needs to be done.

This year, 12 more California counties received failing grades than did last year in terms of air quality. This reflects, in part, the tighter national ozone standards adopted in 2008. The ALA’s State of the Air 2009 Report also found that six out of every 10 Americans live in areas where pollution levels actually endanger their lives.

This means that despite an ever-growing “green” movement that is sweeping across the United States, the ALA’s report indicates that the air in many American cities became even dirtier since last year’s report.

THE REAL COST

There is now data and research that indicates that ozone is more destructive than originally believed. Because of this, in March 2008, the EPA lowered the standard needed for ozone levels to trigger an unhealthy rating.

Ozone, the gas that forms a major component of smog, is created by tailpipe emissions that are cooked by the sun, heat up and form triple molecules of oxygen. These molecules are much less stable than conventional oxygen and are much more damaging to our respiratory systems.

Respiratory problems are a very natural and scientifically established result of air pollution. Polluting particles in the air can especially cause health problems in children, the elderly and the infirm. Additionally, air pollution can aggravate asthma symptoms and worsen allergies.

However, respiratory problems are not the only health issues that can be brought on or aggravated by breathing polluted air. If the pollution is heavy enough and if a person is chronically exposed to the polluted air, serious health problems, including cancer and heart disease, can result from the toxins constantly breathed in through the air.

Look at Los Angeles, which has a lethal combination of heavy traffic, sunshine and heat. Last year, the city had 195 days where the ozone levels were high enough to be unhealthy for sensitive members of the population. On another 55 days, the ozone level was unhealthy for everyone, and on 11 days, the ozone in the air was rated “very unhealthy.”

Particle emission pollution is generated primarily by diesel engines, coal-fired power plants and the burning of wood and other combustible fuels. For California’s coastal cities, much of their pollutants come from ships coming into port. In fact, sea-fairing vessels contribute significantly to both particle and ozone emission air pollution.

Whatever the source, some states are taking very aggressive action in an attempt to combat the problem of air pollution. New York and Washington have been successful in reducing air pollution drastically over the past 10 years, and California is introducing cleaner diesel fuel for everything from semi-trucks to large ships.

There has been some criticism of the ALA’s air quality report because the findings are based on where the EPA monitoring stations are located. In Pittsburgh, for example, one monitoring station sits close to the largest coke plant in the United States. Coke is an important ingredient in the steel manufacturing process and is made by baking coal, which produces large amounts of ash and other toxic particles.

It is not a surprise then that Pittsburgh had the highest recorded number of particle pollution spikes, which are jumps in the number of particles in the air that can last for many hours or even days.

However, it is important to note that the findings are supposed to capture the worst cases of air pollution for each metropolitan area because that is what will have the most negative impact on a population’s health. So, it is actually appropriate to locate monitoring stations where the air pollution problems are most acute and potentially damaging.

While air pollution is a chronic problem across the United States, there are still some places where a taking a fresh breath is just that…a fresh breath.

The healthiest cities list mostly consists of cities in the vast-open spaces of the nation’s heartland. These areas are typically far from heavy industry and massive traffic jams. Cheyenne, Wyoming has the lowest long-term particle average, followed closely by Santa Fe, Honolulu and Great Falls, Montana.

The lowest, in fact almost non-existent, ozone levels were discovered in Billings, Montana, Carson City, Nevada and Fargo, North Dakota. Interestingly, only two eastern cities were on any of the three least-polluted lists. Portland, Maine had among the lowest spikes in particle emissions, and Port St. Lucie, Florida had among the lowest ozone levels.

However, the fact remains, many of us are still not breathing clean air. According to the ALA, six out of every 10 Americans, or 186 million people, currently live in communities where the air they breathe endangers their lives. As a nation, we obviously still have a long way to go.

In the 1920s, farmers succeeded in conquering The Great Prairie Plains of the Midwest. The plains were then transformed into the “amber waves of grain” we know today. However, this transformation came with a heavy price.

In fact, the agricultural triumph over The Plains was the tipping point that changed a typical La Nina-type drought cycle into an enormous environmental disaster that we now know as the Dust Bowl.

Depending on where you are in the world, a drought can have different meanings. According to the United States Weather Bureau, a drought is a period of 21 or more days during which rainfall is no more than 30 percent of the average rainfall for a specific geographical area at a designated time of year. 

The Dust Bowl was an area in the United States that experienced an extended and intense period of drought, which lasted from 1931 until 1939. The states that made up the Dust Bowl were Kansas, southeastern Colorado, northeastern and southeastern New Mexico, and the panhandles of Texas and Oklahoma. 

Throughout the Dust Bowl, soil from roughly 150,000 square miles of farmland was blown by the wind into huge dust storms. Immense clouds of dust filled the sky as far east as New York City, New York and Baltimore, Maryland.

While the Dust Bowl occurred during a period of drought, researchers know that the Dust Bowl drought, while much hotter and drier than a typical drought, did not fit the profile of the periodic droughts that generally hit farther to the south. Actually, while regular climate oscillations may have triggered the initial drying, the contribution of human land degradation played a big part in this atypical disaster.

In the absence of modern agricultural techniques, large-scale crop failures at the drought’s onset reduced vegetation cover, which only exacerbated the heat. Then, the resulting dust storms brought on by the badly eroded croplands also affected the atmospheric moisture content enough to further intensify drought conditions.

In 1931, dust from the seriously over-plowed and over-grazed prairie lands began to blow. And, it continued to blow for eight long, dry years.

As the storms blew across the plains, it came in a yellowish-brown haze from the South and in rolling walls of black from the North. This just wasn’t any wind, this dust-filled wind made even the simplest acts of life difficult. Taking a walk, eating a meal and breathing were no longer easy and they couldn’t be taken for granted.

Most children wore dust masks to and from school, people started hanging damp sheets over windows in feeble attempts at stopping the dirt and farmers could only watch as their valuable crops were blown away. The agricultural devastation that resulted from the Dust Bowl windstorms helped to lengthen The Great Depression, whose effects were already being felt worldwide. 

During the years of normal rainfall, the grasslands in the Dust Bowl states had been deeply plowed and the land had produced bountiful crops of wheat. However, as the drought of the early 1930s worsened, farmers continued plowing and planting, even thought very little could thrive in the parched soil.

The ground cover that once held the soil in place was now gone. The winds had whipped across the fields pulling billowing clouds of dust and dirt into the skies often reducing visibility to just a few feet. The skies would be darkened for days, and it became common for even the most well-sealed homes to have a thick layer of dust on the furniture. In some of the hardest hit areas, dust drifted like snow and covered whatever was in its path, including farmsteads, cars and city streets.

In 1932, there were 14 reported dust storms, also referred to as “black blizzards” or “black rollers.” As conditions worsened, in 1933, the number of black blizzards jumped to 38. These devastating dust storms spread from the Dust Bowl area and affected the entire country. The extensive drought that accompanied the dust storms is said to be the worst drought in United States history because it covered over 75 percent of the country and severely affected 27 states.

The Yearbook of Agriculture for 1934 says, Approximately 35 million acres of formerly cultivated land have essentially been destroyed for crop production; 100 million acres now in crops have lost all or most of the topsoil; 125 million acres of land now in crops are rapidly losing topsoil.

Because this ecological and human disaster caused millions of acres of farmland to become useless, hundreds of thousands of people were forced to leave their homes. These people became known as “Okies” because so many of them came from Oklahoma. Countless Okies migrated to California and other states in hopes of better living conditions and jobs.

However, what they found were economic conditions little better than those they had left behind in the Dust Bowl. Because they didn’t own land and had no home, many people traveled from farm to farm picking fruit and working in the fields for only starvation wages.

With no rain clouds in sight, the drought continued and so did the Dust Bowl storms. On Sunday, April 14, 1935, the worst black blizzard occurred, causing extensive devastation and turning the day to night.

Shortly after Black Sunday, the United States Congress declared soil erosion “a national menace” and established the Soil Conservation Service in the Department of Agriculture. The SCS developed extensive conservation programs, which helped to retain topsoil and prevent irreparable damage to the land.

Farming techniques, including strip cropping, terracing, contour plowing, crop rotation and cover crops were promoted. Farmers were now paid to practice soil-conserving farming techniques.

The SCS and these new land-friendly farming techniques was a great step in the right direction, but the storm was not over yet. By the end the year, experts estimated that about 850,000,000 tons of topsoil had blown off the Southern Plains during 1935 alone. The fear was that if the drought continued, the total area affected would increase from 4,350,000 acres to 5,350,000 acres by the spring of 1936.

Because the Dust Bowl black blizzards raged on and the drought continued, President Franklin D. Roosevelt initiated the Shelterbelt Project in 1937, which called for large-scale planting of trees across The Great Plains, stretching in a 100-mile wide zone from Canada to northern Texas. The goal was to protect and preserve the land from erosion.

Native trees, including green ash and red cedar, were planted along fence rows separating properties, and the farmers were paid by the government to plant and cultivate these trees. Ultimately, the project cost roughly 75 million dollars over 12 years, and had somewhat limited success.

However, as time passed, even thought the drought continued, further land conservation efforts began to make progress. The extensive work re-plowing the land into furrows, planting trees in shelterbelts and other conservation methods had finally resulted in a 65 percent reduction for soil blowing.

In the fall of 1939, after nearly a decade of drought, the rain finally came. This brought an end to the black blizzards of the Dust Bowl and allowed The Plains to recover and once again become golden with wheat.

In today’s ever-changing world, in areas where vegetation loss often leads to increased wind erosion, it appears that history could repeat itself and we could experience Dust Bowl-type droughts again in the future.

Researchers with NASA’s Goddard Space Flight Center report that, although it is not possible to predict the exact time, history suggests that another great drought could certainly occur in the future.

The first step for anyone wanting to predict the risk of a future catastrophic climate event is to look at past occurrences. Unfortunately, however, good rainfall records only go back about 100 years, and accurate atmospheric records only exist for the last 50 years.

With that said, historical measurements do suggest that droughts have been a fairly regular event in this country. North America experienced a dry spell during the 1950s and another in the late 1980s. NASA’s research suggests that there was almost a drought in the 1970s, but for some reason it did not happen.

On a much longer timetable, sediment records, tree rings and other alternative evidence of climate change suggest that The Great Plains has actually weathered multiple droughts, which lasted significantly longer than the Dust Bowl.

These severe droughts appear to have happened once or twice a century over the last 400 years. Some evidence even points to droughts lasting over a decade during the late 13th and 16th centuries, which were much more devastating than the droughts of the 20th century.

It seems that history indicates that we can expect much worse than the 1930s Dust Bowl in the future, but knowing when and where remains anyone’s guess.

Apparently, it is true that desperate times call for desperate measures. Reportedly, Beijing’s 17 million residents are now under very limited and restrictive driving, manufacturing and constructing guidelines. These restrictions are all being imposed in an attempt to clean up one very polluted city.

It is reported that major construction is to stop, factories are to be shut down and half the automobiles are to be grounded every day until after the Olympics.

While the Beijing Environmental Bureau said that the air “will be safe, everyone can be at ease,” many athletes, environmentalists as well as authorities from numerous countries attending the Olympics have significant concerns.

Chinese officials, however, contend that safety is of the utmost importance. Officials seem to have a lot of confidence that they can effectively control the country’s air pollution problem, even if that means trying to control Mother Nature herself.

By using possibly the world’s most sophisticated computer system, Chinese authorities are not only watching the weather and wind patterns surrounding Beijing, they are prepared to attempt to try to change what Mother Nature dishes out.

By tracking pollution from as far away as India, China is focusing heavily on surrounding provinces and their big pollution sources. At one steel plant located 300 miles from Beijing, the boss is poised to close the plant if high winds start blowing this distant, but dangerous, faraway pollution into or near Beijing where it would likely be trapped by mountains.

Once the pollution is entrapped by the mountains, the only viable solution would be rain. And, according to Chinese authorities, scientists are prepared to try that too. How would they do this? Simple. Artillery shells filled with a chemical thought to trigger rain showers would be shot into the sky with hopes of rain.

No one, however, can adequately control the weather. So, with apparent good reason, regardless if China says it’s a good-air-quality-day or not, there are many doubters in the crowd.

Consider this. Some pollution monitors have been relocated to the suburbs, where cleaner air can twist daily pollution results and make the overall contamination numbers look better than they really are.

Legitimate concerns for the health of the Olympic athletes and visitors, not to mention the Chinese citizens, remain. While the government has recently spent millions to clean up the city, the pollution problem in China simply cannot be fixed with a few quick, and possibly temporary, fixes.

The City of Beijing has undergone numerous improvements for the games. In fact, the government spent approximately $57 million to renovate more than 5,000 public restrooms. Also, thousands of Olympic volunteers are learning English and the ABCs of interacting with foreigners.

Chinese officials have also taken environmental actions aimed at dissipating Beijing’s air pollution before the games by spending more than $15 billion on drastic antipollution measures, including relocating 200 factories and steel mills outside the city limits.

According to a recent Mother Jones article, China has spent $3.6 billion and taken some extreme steps to clean up the capitol before the summer games. One of the changes China has made is building four new subways in order to encourage more public transportation and cut down on traffic. One million vehicles will also be banned during the Olympics.

However, the truth is that no amount of vitamins, regimens or athletic stamina will prepare many of the world-class competitors for the sort of severe air pollution they will face in Beijing. Numerous health and athletic experts have long been concerned whether athletes’ lungs will be able to adjust to all the smog and chemicals that plague the entire Chinese environment.

While these actions are a great step in the right environmental direction, China needs more than a quick-fix for its crippling environmental issues. According to FinancialNirvana.com, many environmental experts believe China’s problems may be attributed to a weak legal system and corruption, poverty, government policies that put job growth ahead of having a healthy environment as well as two decades of double-digit industrial growth.

In addition to this, Worldwatch Institute’s State of the World 2006 report notes that acidification has spread to approximately 30% of China’s cropland. The Report also states that China has 16 cities with the worst air pollution in the world.

Even more remarkable and astonishing is the fact that China’s Ministry of Science and Technology estimated that roughly 50,000 of the country’s newborn babies die every year due to the unhealthy consequences of air pollution.

Sometimes it’s the little things that say the most

Consider the latest news of a keel-crippling algae bloom that covered about a third of the Olympic sailing course in Qingdao, China. This algae overgrowth resulted in the deployment of a small army of workers, a large fleet of boats and a full brigade of dump trucks and bulldozers that have been desperately trying to clear up this embarrassing, yet expected, component to China’s assertion of hosting a ‘green games’ Olympics.

What this means is that numerous international competitors desperate for practice have been forced to stay in dry dock until this dangerous mess is cleaned up. While this kind of environmental roadblock may be foreign to many Olympic competitors, it is far from atypical in the world’s most polluted nation.

Today, fully 70% of China’s seven major rivers are severely and dangerously polluted. In addition, 80% of its rivers fail to meet standards for fishing and 90% of China’s cities suffer from some degree of significant water pollution. What this means for those who live in China is that over 700 million Chinese drink fetid water of a quality well below World Health Organization’s standards.

Meanwhile, liver and stomach cancers related to water pollution are among the leading causes of death in the Chinese countryside. And, 21 cities along the Yellow River are now characterized by the highest measurable levels of deadly pollution.

As for this particularly extensive algal bloom in Qingdao, the cause is clear — a massive misuse of agricultural fertilizer. A not-so-well-known-fact is that China is the world’s largest fertilizer user, consuming more than 50 million tons each year.

This problem is exacerbated by untrained peasants applying far too much fertilizer to their meager plots with the false hopes and dreams of boosting their already scanty yields. The obvious result has been a new kind of flooding crisis — a flood of excess and unneeded fertilizer runoff that ultimately ends up flooding into neighboring rivers and streams.

With this toxic runoff mixture, fertilizer nutrients such as nitrogen and phosphates have triggered an explosion of algal blooms as part of a broader process of eutrophication. This eutrophication process quite literally sucks the oxygen out of the water and kills all of the plant, fish and aquatic life.

The obvious catastrophic environmental result is an extremely foul-smelling and murky body of water incapable of sustaining life.

Another perfect example of this algal bloom epidemic is the blooms that keep pounding China’s third-largest lake, Lake Tai. This notable lake has long been famous for its classic beauty and is considered a favorite tourist attraction. Lake Tai also supplies water to approximately 30 million people.

The cost of cleaning up of the lake alone is estimated at more than $14 billion. In addition to this expense, many Chinese citizens have been buying bottled water at a feverish pace as a result of Lake Tai’s repeated algal blooms. This increased demand for fresh drinking water has driven up the price of bottled water.

China’s algal bloom epidemic is not restricted to its rivers and lakes. China’s coastal shorelines are also suffering severely from a growing occurrence of red tides, an oceangoing version of eutrophication.

This problem is particularly relentless in the relatively shallow Yellow and Bohai Seas off northern China where Qingdao is located and where there is less tidal exchange. The red tides are rapidly destroying fish and devastating valuable marine life. China has seen an astonishing 40-fold increase in the incidence of red tides in the past few years.

The overall picture being painted by China’s pollution woes is one of a large country choking to death and drowning on a wide variety of deadly pollutants. Because of the country’s toxic environment, many Olympic athletes have chosen to train in adjacent countries, like Japan and South Korea, and will only fly into China for brief stopovers during their specific sporting events.

What that says about today’s China speaks volumes. This country’s need to deal with its very real pollution crisis is obvious and is emerging as one of the most far-reaching and irresponsible environmental disasters the world has ever seen.

The Hudson River is beautiful. It begins in the Adirondack mountains, a little over 4200 feet from the base of New York State’s highest peak, Mt. Marcy, and flows for 315 miles; past the extraordinary rock formations known as the Palisades, to the southern tip of Manhattan, where it meets the Atlantic Ocean.

At the lower end of the Hudson, the freshwater from the mountain mixes with salt water from the Atlantic, forming an estuary. Past home to a variety of commercial fisheries, the Hudson River has been known to contain up to 200 different types of fish.

Yet despite its natural beauty, the Hudson River is a very dangerous place. Beneath the pristine surface is a PCB graveyard, where deposits of the known carcinogen have settled into the sludge that sits at the bottom of the river. For years environmentalists have been working to get it cleaned up. There is just one problem: the company responsible for the majority of the PCB deposits that pollute this national treasure is a very big company, with very close friends in Washington.

That company, General Electric Company (GE), has spent millions of dollars trying to convince Congress and the public that the proposed cleanup of the Hudson River will actually make the PCB problem worse.

Their main reason for resisting the original EPA-sponsored cleanup proposal, projected to cost in excess of $500 million, is a “moral” argument, not a financial one, says GE spokesperson, lawyer, and former CEO Jack Welch. He insists the cleanup is not necessary because PCB deposits have settled into the muck at the bottom of the river, which Welch says means that “the river is cleaning itself.” Scientists, environmentalists, and a variety of non-profit organizations (with no ties to GE ) say otherwise.

Despite the passage of the 1976 Toxic Substance Control Act, which banned PCB manufacturing and required any use of PCBs be done within “totally enclosed systems,” numerous tests for PCB concentration have continued to yield extremely high levels of the contaminant throughout the Hudson River. In 1992, Department of Environmental Conservation(DEC) fish sampling data revealed a 300% increase in PCB levels of fish in the Upper Hudson.

As far back as 1977, when the EPA’s Clean Water Act made it illegal to dump any PCBs into navigable waters, the Hudson was becoming known as a toxic river. Yet six years later, an EPA study of the “PCB problem” in the Hudson River resulted in a Record of Decision (ROD) calling for no action. This caused extreme concern in the environmental community as it came even as the FDA reduced the limit for ppm PCBs in fish fit for human consumption, from 5 to 2, in response to new data.

In 1989, DEC took the lead and asked the EPA to reconsider their 1984 ROD of “no action.” DEC followed their recommendation by releasing the Hudson River PCB Action Plan, which would have required 250,000 pounds of PCBs be dredged from the bottom of the Hudson River. It has been 20 years since that recommendation was made, but no dredging has ever been done.

The “self-cleaning” nature of the Hudson, according to Welch, makes it dangerous to dredge the river. All that muck will come up, he says. Welch believes that if we leave it alone, river water will just naturally keep getting cleaner and cleaner.

Reality, however, does not support this argument.

In 1993, more than 15 years after PCB dumping stopped, DEC found an “oily liquid” at the GE site at Allen Mills that contained 72% pure PCBs. They also found seven GE PCB-laden capacitors in the water near GE’s Hudson Falls plant. This prompted DEC to order GE to clean up the land around the river, but they have yet to require any cleanup of the river, itself.

Meanwhile, scientists discovered that evaporation of PCBs allows them to become airborne–meaning PCBs in the sediment of the river, which are exposed at low tide, can potentially be breathed in by residents or tourists. This prompted research into PCB levels in locals. The results were not good.

High PCB levels were found in the bodies of people who do not eat fish. Additional studies showed high levels of PCBs in tree swallows and a 16-week old bald eagle tested for PCBs was found to have 71 ppm PCBs in its body fat.

Since then, a Natural Resources Damages Claim has been made, and the EPA has begun work on a feasibility study to outline the scope of work involved in a Hudson River cleanup. In 2002, they came up with a comprehensive plan that included removing “enough PCB-laden muck to fill more than 800 Olympic swimming pools from the bottom of the river.”

The cost of the program was estimated at more than $500 million. But in October of 2005, EPA announced a Consent Decree, which would, if accepted, allow GE to limit their cleanup to the first two phases of the original 2002 dredging plan, which would only cover about 10% of the site.

Since then, two separate lawsuits have been filed to force the EPA to disclose documents pertaining to the discussions they have had with GE and the White House, regarding the proposed Hudson River cleanup. But so far, mum’s the word. For political reasons the EPA prefers to keep secret the information that explains their sudden reversal of policy regarding a comprehensive cleanup of the Hudson river.

GE is putting an enormous amount of time and money into avoiding responsibility for the cleanup, despite the fact that they used and dumped PCBs into the land and water long after they knew they were one of the most toxic substances known to science.

In 1964, a report produced by the Tennessee Department of Public Health stated that the Chattanooga Creek was “without a doubt, the most grossly polluted stream in the Chattanooga area.”

In 1969, the Department of Health, Education and Welfare determined that Chattanooga, Tennessee had the poorest air quality in the nation. This was due, in large part, to a heavy manufacturing industry that included chemicals and pesticides.

Many cities have faced these same challenges. Many cities still do. But Chattanooga’s responses and solutions have been unique, and very successful.

One of the first things the city did was create, and have approved by the state, the Hamilton County Air Pollution Control Bureau. The Bureau was charged with establishing air quality regulations for the city. In an effort to ensure compliance of these regulations, the Bureau worked directly with the manufacturing sector. At the time, the primary need was for smokestack “scrubbers”, which remove most of the toxic by-products typically released by industrial smokestacks.

The manufacturing sector responded quickly and creatively. Not only did they agree to the $40 million in renovations that was needed, but local entrepreneurs chose to build the scrubbers in town. Today the scrubbers are still being manufactured, and are being exported worldwide. Thus, a profitable industry was created, while simultaneously improving air quality.

The city began holding “community visioning” meetings, seeking resident assistance with the environmental and economic troubles it was facing. One outcome of those meetings was the creation of the Moccasin Bend Task Force. This task force studied the 22-mile long Tennessee River and, with the input of hundreds of local citizens, developed the Tennessee River Park Master Plan. The Master Plan eventually resulted in the development of a 23-mile River Walk. The city maintains it through a yearly River Rescue clean-up effort, and it has enabled Chattanooga residents and tourists to enjoy the river again. The Master Plan didn’t just focus on the banks of the Tennessee River. It also included strategies for cleaning up and beautifying the banks of the creeks that feed into the river. In addition, a water treatment facility was built farther upstream, to aid in purifying the streams and lake. Now, where “no swimming” signs used to be the prominent feature, you can instead see people swimming, boating, or simply walking along the river’s edge.

From the river, the environmental revitalizing moved to the downtown district. Trees were planted along the streets. Not just for aesthetic purposes, but to help reduce pollution. The trees are purchased from a local, private nursery. Street pavers were built to help reduce the effects of storm water run-off. Air and traffic pollution have been reduced with the introduction of an electric mass transit system. The technology and vehicles were developed and built locally, and are now being exported globally. People who work downtown can park in garages at the edge of the downtown district, then take electric shuttles to their final destinations. The money generated from the parking garages helps cover the cost of the electric vehicles.

One of the most aggressive and innovative projects is the South-Central business district. Being built as an eco-industrial park, the goal is zero emissions. This means that the waste products from one industry become resources for another within the district.

Chattanooga has excelled at developing a sustainable community, because it has re-integrated the human element. At the heart of most of its initiatives has been the Chattanooga citizens themselves. The community vision meetings were the cornerstone for most of the changes that have been made. But the citizens don’t just offer ideas, they help implement and maintain them. This is done, not only through clean-up efforts like River Rescue, but also through everyday activities. The Orange Grove Recycling Center is a perfect example.

Though it could use machinery to separate the recyclable materials that come in from the nearly 60,000 homes and municipal drop-off sites, the Center instead employs about 100 developmentally disabled adults. Not only does manual sorting reduce industrial pollution, but it also gives an often-ignored part of the population a sense of purpose and belonging. The workers are paid for their time, and are given the opportunity to become and integral part of this community’s sustained environment.

Chattanooga Neighborhood Enterprise was yet another result of the community vision meetings. It is currently creating a mixed-use, mixed-income development in a part of downtown Chattanooga’s Southside district. Included is an elementary school that will allow children in the area to walk to school for the first time in years.

While most cities, nationally and globally, make an effort to reduce negative affects on the environment; few (if any) have attained the level of success enjoyed by Chattanooga. Here, industry is not the enemy, but instead has offered viable and effective solutions. Here, the citizen and the government official aren’t at odds. Rather, they work together to creatively address the environmental challenges the city has faced.

Chattanooga has become one of the few cities designated as an EPA attainment city. This has been due, in large part, to combined efforts of Chattanooga citizens and city officials.

From “most polluted city in the nation” to one of the best (possibly the best) models of an environmentally healthy and sustainable city, in under 40 years. Not bad.

Making Aluminum in Western Australia

Australia is renown for having beautiful coastlines and expanses of white sandy beaches, as well as being one of the driest continents in the world. Therefore, It comes as a suprise to find situated on what could be described as a magnificent coastal stretch of Western Australian water, an Industrial region that spans 12 kilometers along the foreshore from north to south and is approximately 2 kilometers wide. This region is located 37 kilometers south of Perth, the Western Australian capital, and takes up 1,180 hectares of land, 80 % of which a small, tiny, little company called Alcoa occupies.

Small may have been a slight exaggeration on my part, after all Alcoa only has 250 operations that spread across a tiny community of 30 nations, with Western Australia being lucky enough to acquire three of these magnifiers of beauty, restorers of nature and revitalizers of natural resources.

Hey, it is a well-known fact that Australia is the lucky country!

Alcoa, also known as the Aluminum Company of America, operates in this Industrial region of Kwinana, 15 km south of Fremantle, Perth and a stone throw from the central business district. The Kwinana refinery began in 1963 and produces 1.9 million tones of aluminum annually. Coupled with the other Western Australian refineries, Australia produces 15% of the worlds Aluminum, which is a fabulous feat considering Alcoa depletes natural resources including Australia’s precious water supply, quicker than mother nature can reproduce.

This makes perfect sense when Australia is one of the driest continents on earth.

In a recent study of Perth, the CSIRO or Commonwealth Scientific and Industrial Research Organization reported:

a 10% decrease in average rainfall and an estimated higher median temperature for the region. They predict this figure will impact upon the ground water of Perth reducing its holding by up to 50%, and they predict that in the future it will become even hotter.

Alcoa plays a significant part in this process because not only do they use natural resources, they also contaminate them, the land surrounding them, the air we breathe, and our glorious ozone layer. It’s like a bad Christmas present that you can’t return, or sell on eBay.

Without taking into consideration the size of the Alcoa plant in Kwinana — because of its insignificance causing an environmental impact — and the lack of incredibly loud noise associated with production, it is hard to ignore the captivating stream of carbon monoxide emissions, sulphur dioxide (So2), Benzene and volatile organic compounds (VOC) cascading into the air.

What a truly magnificent sight! Plumes of smoke 30-100 meters high. It brings a tear to my eye, and coughing to my lungs. Also, my nose is running.

These plumes then settle and hang around for up to 24 hours, which adds to the entertainment factor because you can now choose, if you wish, to run and frolic in them instead of just viewing their destruction from afar.

Sulphur dioxide only attacks the throat and lungs of the creatures residing nearby, making breathing difficult, and attacks plant vegetation, eventually destroying it. Volatile organic compounds erode our ozone layer and allow harmful UV rays to penetrate the atmosphere. Of course, Alcoa, state:

they are committed to using fewer resources, reducing toxic waste and pollution and becoming more environmentally friendly. They also swear they will reduce greenhouse gas emissions by 25%, and that they have introduced cleaner production programs.

In making these promises, Alcoa also applied for a new license.

The truly wonderful thing is, Alcoa is expanding. In 2003, they built new bauxite residue and storage ponds that are clay-lined, which of course prevents residue from permeating the earth.

This by-product of aluminum manufacturing takes years to dissipate and these ponds like the Alcoa operation are only small; they cover a tiny area of 44 hectares.

With Kwinana dubbed the Cancer Capital of Western Australia and many bizarre types of Cancer killing off the workers of Alcoa, it makes perfect sense that the Western Australian government is allowing brand new residential areas to be constructed in close proximity.

The real estate offices have been inundated with calls and they have almost sold out of potentially ‘fabulous’ blocks with a view. You can see that magnificent plume and there may even be a possibility you can play in it.

Of course, research has been conducted to ensure the environment is safe to build on. These tests were carried out by Alcoa themselves, because the Department of Minerals and Energy thought that the Department of Environmental Protection was doing it, and they in turn thought the Department of Health were responsible, so therefore they were unable to decide who should carry out the relevant studies. In addition, they thought Alcoa had done such a fantastic job, they would borrow their study instead.

Talk about shifting the responsibility. Maybe they thought Alcoa resembled a hot potato.

Who could honesty expect anything more from a governing body who find it challenging to issue a license to destroy mother nature and rape the earth. And, we worry about gun licenses!

Alcoa now has a brand-new license to kill, and no, the company is not related to James Bond. They will, however, continue to pollute the air we breathe with toxic emissions, destroy vegetation, create acid rain, drain our natural resources and contaminate the earth.

Our future is so bright I definitely will have to wear shades, and protective clothing and sunscreen and an oxygen mask and…

“The Buncefield depot is a major distribution terminal operated by Total and part-owned by Texaco, storing oil, petrol as well as kerosene which supplies airports across the region, including Heathrow and Luton.

The country’s fifth largest fuel distribution depot, it is also used by BP, Shell and British Pipeline.”

“The fire chief described the incident at the Buncefield fuel depot near Hemel Hempstead, after 0600 GMT, as possibly the largest in peacetime Europe.”
