*And you hoped you would never have to ask. Intro. First things, first. The EPA
knew . Even before the crappy earthen retaining wall spilled its toxic load of chemicals into a waterway in Tennessee, the federal government understood that so called “clean coal” was nothing but a conjurer’s trick. The process creates vast swamps of toxic chemicals that seep and pollute nearby farmland and water supplies with poisonous, carcinogenic chemicals.
The risk assessment examined 181 coal combustion waste disposal sites throughout the country and found that unlined coal ash waste ponds pose a cancer risk 900 times above what the government considers "acceptable." The report also found that coal ash disposal sites release toxic chemicals and metals such as arsenic, lead, boron, selenium, cadmium, thallium, and other pollutants at levels that endanger human health and the environment.
If the industry was required to use
composite liner in their storage facilities, the risk of slow leeching and of sudden spills—like the one last week and the one in 2000 in Martin County—would be greatly reduced. But apparently the EPA exists only to service the utility industries, and so they get to store a bunch of wet sludge in dirt bunkers that leak and break.

Thallium Can Kill You The Tennessee Valley Authority will not tell you that thallium is so toxic it is a poison of choice for villains in mysteries and that it was banned as a rat poison and insecticide years ago. Nor will they let you know that it is a major public relations nightmare. When companies have an environmental spill of the stuff , attorneys recommend starting the good neighbor advertising campaign even before you start the clean up.

(P)reliminary TVA tests suggest the millions of people who get their drinking water from the 652-mile Tennessee River shouldn't worry.
"We have no reason so far to know that is unsafe," he told a news conference, noting TVA is working closely with the Tennessee Department of Environmental and Conservation and the federal Environmental Protection Agency. The water intake for the town of Kingston is about six miles downstream of the power plant.
"It is possible it is going to have some metals in there," said Laura Niles, regional spokeswoman for the EPA in Atlanta.
http://www.forbes.com/feeds/ap/2008/12/24/ap5858629.htmlThat’s the monetary risk management I was telling you about.
Now, here is everything you should know about thallium in light of this fact that came out a couple of days later.
http://www.tennessean.com/article/20081227/GREEN02/812270345/1001/RSS6001Elevated levels of lead and thallium have been found in test samples from river water taken near the ash slide at TVA's Kingston Fossil Plant in Harriman, Tenn., a TVA official said Friday evening.
The rest of the article is full of fun, feel good facts about how the thallium will not harm you. Ignore that part. Go back to the textbook. Note that thallium can be absorbed through the skin, inhaled through the lungs or it can be ingested (eaten)—or all three at once. Thallium in the water can dry and get into the air where the dust can coat things that are then touched. Or, you can breathe it. Some plants concentrate it, so you may be eating it later for supper. It will show up in fish later, too, assuming they ever come back.
Acute thallium poisoning is primarily characterized by gastrointestinal symptoms, while neurologic findings predominate with chronic exposure. The neurologic manifestations tend to progress, even despite decreasing blood thallium levels. Thallium toxicity is characterized by a painful ascending peripheral neuropathy and alopecia; this clinical manifestation presents 2-3 weeks after an acute poisoning.
In other words, you get the stomach flu at first. Later, you start to get numb, beginning with your legs, and your hair falls out, and you may have trouble breathing. Severe symptoms include seizures, coma and death. The effects are cumulative (they add up) and will continue even after the exposure stops.
Thallium is lethal to humans. The lethal dose for humans is 15-20 mg/kg (around 1 g for a 70-kg person). Nonfatal effects occur below this dose. However, it is conceivable that even smaller doses can still cause fatality (minimal reported dose was 8 mg/kg). In addition, some treated patients have survived exposure up to 28 mg/kg.
http://emedicine.medscape.com/article/821465-overviewOne gram is not much. Makes you wish that the EPA would tell us exactly how high the thallium levels are in the coal ash and in the water around the spill site.
Here is a document put out by the WHO in 1996 about thallium.
http://www.inchem.org/documents/hsg/hsg/hsg102.htmPertinent points:
The thallium from coal plants is primarily soluble thallium chloride. It dissolves in water. That means that
Terry Johnson of the TVA was either lying or making things up when he claimed that the thallium in the water would settle to the bottom of the river in this news report.
http://www.tennessean.com/article/20081227/GREEN02/812270345/1001/RSS6001Like potassium chloride, it will dissolve. Fun, fun. Don’t even look at that water until the EPA tells you what the thallium concentration is. “Elevated” just does not cut it in my book. “Elevated” can kill you.
Here is what farmers can expect according to the WHO document.
The fate of thallium added to soil (in deposited fly ash, for
example) depends largely on soil type. Retention will be greatest in
soils that contain large amounts of clay, organic matter and
iron/manganese oxides. Incorporation into stable complexes causes
enhanced thallium concentrations only in the upper levels of soils.
The uptake of thallium by vegetation increases as soil pH decreases.
In some strongly acid soils significant amounts of thallium can be
leached to local ground and surface water.
In most parts of the South, the soil is strongly acidic. River beds tend to have lots of organic matter. My guess is that there is the potential for thallium to settle in for a long stay unless it is cleaned up out of the water now.
Thallium can affect plants ability to grow by interfering with the nitrogen fixing process.
It is also toxic to aquatic plants and fish.
If anyone tells you that thallium does not cause cancer, that is because no one has studied to see if it causes cancer.
Urine tests are available to measure human exposure and may be the easiest way to monitor the health of people in the affected area who are at risk from multiple sources---air, water, skin.
II. So Can Lead Most people are familiar with lead poisoning, so I will not go into great detail.
http://www.bookrags.com/research/urban-contamination-enve-02/Lead is a trace metal of particular concern, and two predominant pathways for the uptake of lead have been identified in humans: soil and dust ingestion, and consumption of home grown foods. Depending on the extent of exposure, individuals may develop symptoms of acute or chronic lead poisoning. Symptoms or results of exposure include severe anemia, acute nervousness, kidney damage, irreversible brain damage, or death. Preschool children and women of child-bearing age are especially at risk. It has also been reported that people exposed to lead and cadmium in drinking water suffered from increased chronic kidney disease, skin cancer, heart disease, and anemia.
At this point, I would start wondering if anyone has done studies on the additive effects of two or more different neurotoxic metals on the same test animal….
http://books.google.com/books?id=qyoNMmh77PAC&pg=PA44&lpg=PA44&dq=%22additive+effects%22+neurotoxic+metals&source=bl&ots=3F68Iu_7y1&sig=09BIP772kFVaYTzD7UqH34orf40&hl=en&sa=X&oi=book_result&resnum=2&ct=resultYep. Just as I suspected. Different poisons that affect the body’s nervous system can be more dangerous if you are exposed to them together. For instance, two heavy metals can act in similar ways. Or, the body may use the same method to clear them, so exposure to one may reduce your ability to get rid of another. That means that an alphabet soup of poisons may be worse than exposure to each toxin separately.
III. Don't Drink the Arsenic Everyone knows that arsenic is bad for you. You are allowed to have up to 10 micrograms/liter of arsenic in your water, and many wells are naturally contaminated the stuff which can leach in from the surrounding rocks.
http://water.usgs.gov/nawqa/trace/arsenic/Bangladesh has a severe problem with arsenic in its water.
Arsenic is associated with bladder and skin cancer. There is a blood test to determine if you have been exposed. Arsenic is ingested, either through water or food. There is both acute, fatal poisoning and a chronic poisoning syndrome.
And this just in….http://www.google.com/hostednews/ap/article/ALeqM5hCuUPH4bNcOtq-0PajMZoG1IbExwD95CKMC00Some water samples near a massive spill of coal ash in eastern Tennessee are showing high levels of arsenic, and state and federal officials on Monday cautioned residents who use private wells or springs to stop drinking the water.
Samples taken near the spill slightly exceed drinking water standards for toxic substances, and arsenic in one sample was higher than the maximum level allowed for drinking water, according to a news release from the Tennessee Valley Authority, which operates the power plant where the spill occurred, the Environmental Protection Agency and other officials.
TVA spokesman Jim Allen said there are four private drinking water wells in the area affected by the spill and the agency should have tests from them this week.
"I think they were beyond the actual slide point of the material," EPA spokeswoman Laura Niles said of the wells. "There shouldn't be direct impact, but that's why they are sampling."
How does she know the slide point? The EPA did not even know how much material was in the spill at first. Do you think she is getting her answers from the owners of the utility plant who continue to move more aggressively in their public relations containment disaster plan than they do in their coal ash spill containment disaster plan? Will Bush write these people a pardon and hand them a superfund check on his way out the door? Has the EPA checked to see if wells at a distance have arsenic? I.e. if it occurs naturally in the area? For all we know, chemicals have been leaching through the dirt that surrounds the toxic coal ash for years, contaminating the local ground water. If you go back to the federal government's own arsenic in groundwater mapping site and click on the map
http://water.usgs.gov/nawqa/trace/pubs/geo_v46n11/fig3.htmlyou will see that
Tennessee and the South have low levels of arsenic in groundwater. The chemical is a problem in the west, particularly in mountain areas. It seems to me that the most likely source of arsenic in wells in Tennessee would be the nearby toxic waste dump. I am not a lawyer, but if I had a well that I could not drink from, I would seriously consider consulting an attorney right now.
IV. Manganese, Chromium, Barium Set Out to Sea From the
New York Times today:
http://www.nytimes.com/2008/12/30/us/30sludge.html?_r=1The inventory, disclosed by the Tennessee Valley Authority on Monday at the request of The New York Times, showed that in just one year, the plant’s byproducts included 45,000 pounds of arsenic, 49,000 pounds of lead, 1.4 million pounds of barium, 91,000 pounds of chromium and 140,000 pounds of manganese. Those metals can cause cancer, liver damage and neurological complications, among other health problems.
And the holding pond, at the Kingston Fossil Plant, a T.V.A. plant 40 miles west of Knoxville, contained many decades’ worth of these deposits.
Manganese :
Manganese is an essential trace element in the body, but you can have too much of a good thing.
Manganese effects occur mainly in the respiratory tract and in the brains. Symptoms of manganese poisoning are hallucinations, forgetfulness and nerve damage. Manganese can also cause Parkinson, lung embolism and bronchitis. When men are exposed to manganese for a longer period of time they may become impotent.
A syndrome that is caused by manganese has symptoms such as schizophrenia, dullness, weak muscles, headaches and insomnia.
Because manganese is an essential element for human health shortages of manganese can also cause health effects. These are the following effects:
- Fatness
- Glucose intolerance
- Blood clotting
- Skin problems
- Lowered cholesterol levels
- Skeleton disorders
- Birth defects
- Changes of hair colour
- Neurological symptoms
Chronic Manganese poisoning may result from prolonged inhalation of dust and fume. The central nervous system is the chief site of damage from the disease, which may result in permanent disability. Symptoms include languor, sleepiness, weakness, emotional disturbances, spastic gait, recurring leg cramps, and paralysis. A high incidence of pneumonia and other upper respiratory infections has been found in workers exposed to dust or fume of Manganese compounds. Manganese compounds are experimental equivocal tumorigenic agents.
http://www.lenntech.com/periodic-chart-elements/Mn-en.htmManganese can also cause animal and plant toxicity.
Chromium Like manganese, chromium is an essential trace element, but if you breathe it you can get sick. It can cause rashes and lung problems. Breathing chromium over the course of several years can increase your risk of lung cancer. Usually, this is part of an occupational disease. There is a blood and urine test.
http://www.atsdr.cdc.gov/csem/chromium/treatment_management.html Barium It’s used to make rat poison. It has a water soluble, toxic form.
At low doses, barium acts as a muscle stimulant, while higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, dyspnea and paralysis. This may be due to its ability to block potassium ion channels which are critical to the proper function of the nervous system.
http://en.wikipedia.org/wiki/BariumWith proper medical care, the people who live in the affected area may do alright. The river itself may be a long time coming back. Eight years later, Coldwater still has not recovered from its toxic coal sludge spill.
http://www.ohvec.org/links/news/archive/2004/fair_use/10_11.htmlEnvironmentalists continue to push for improved regulation of mammoth slurry dams, hundreds of which dot the nation. "There are 223 more of these in Appalachia ," Spadaro said. "There are better, alternative methods of disposal of the waste, but that would cost the coal industry $1 more per ton. So it won’t happen."
Massey says the area has healed and been "reclaimed." But Chapman says he’s still waiting and watching for fish — wildlife officials say the slurry killed an estimated 1.6 million in more than 70 miles of stream — to return to his stretch of Coldwater. He used to see mink and muskrat, too.
"I am not against coal mining, and neither are most people here," he said. "I don’t even know that we need new laws. How ’bout we use the ones we have?"
