Mining reaps huge profits for the companies that own them and provides employment to a large number of people. It is also a huge source of revenue for the government. Despite its economic importance, the effects of mining on the environment is a pressing issue. Mining activities require the clearing of large areas of land. The chemicals used in the mining process often escape into the environment causing pollution. Watch this video to know how mining affects the environment.

Eco-Rehabilitation of Biodiversity in Forest Destroyed by Gold Miners - TvAgro by Juan Gonzalo Angel
 
22:42
Twitter @juangangel The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Besides creating environmental damage, the contamination resulting from leakage of chemicals also affect the health of the local population. Mining companies in some countries are required to follow environmental and rehabilitation codes, ensuring the area mined is returned to close to its original state. Some mining methods may have significant environmental and public health effects. Nuss and Eckelman (2014) provide an overview of the life-cycle wide environmental impacts of metals production associated with 62 metals in year 2008. Erosion of exposed hillsides, mine dumps, tailings dams and resultant siltation of drainages, creeks and rivers can significantly impact the surrounding areas, a prime example being the giant Ok Tedi Mine in Papua New Guinea. In areas of wilderness mining may cause destruction and disturbance of ecosystems and habitats, and in areas of farming it may disturb or destroy productive grazing and croplands. In urbanised environments mining may produce noise pollution, dust pollution and visual pollution. The implantation of a mine is a major habitat modification, and smaller perturbations occurs on an larger scale than exploitation site, mine-waste residuals contamination of the environment for example. Adverse effects can be observed long after the end of the mine activity. Destruction or drastic modification of the original site and anthropogenic substances release can have majors impact on biodiversity in the area. Destruction of the habitat is the main component of biodiversity losses, but direct poisoning caused by mine extracted material, and indirect poisoning through food and water can also affects animals, vegetals and microorganisms. Habitat modification such as pH and temperature modification disturb communities in the area. Endemics species are especially sensitive, since they need really specific environmental conditions. Destruction or slight modification of their habitat put them at the risk of extinction. Habitats can be damaged when there is no enough terrestrial as well by non-chemicals products, such as large rocks from the mines that are discarded in the surrounding landscape with no concern for impacts on natural habitat. Concentration of heavy metals are known to decrease with distance from the mine, and effects on biodiveristy follow the same pattern. Impacts can vary a lot depending on mobility and bioavailability of the contaminant : less mobile molecules will stay inert in the environment while highly mobile molecules will easily move into another compartment or be taken up by organisms. For example, speciation of metals in sediments could modify their bioavailability, and thus their toxicity for aquatic organisms. Bioaccumulation plays an important role in polluted habitats : mining impacts on biodiversity should be, assuming that concentration levels are not high enough to directly kill exposed organisms, greater on the species on top of the food chain because of this phenomenon. Adverse mining effects on biodiversity depends on a great extend on the nature of the contaminant, the level of concentration at which it can be found in the environment, and on the nature of the ecosystem itself. Some species are really resistant to anthropogenic disturbances, while some other will completely disappear from the contaminated zone. Time alone does not seem to allow the habitat to recover completely from the contamination. Remediation takes time, and in most of the cases will not enable the recovery of the diversity present before the mining activity.

Sulfur Dioxide & Exposure Concerns
 
04:08
Sulfur dioxide (SO2) is one of a group of highly reactive gasses known as oxides of sulfur. It is a colorless gas with a pungent and suffocating odor. It is a common air pollutant found in many parts of the world. Much of the sulfur dioxide in the air comes from the burning of coal and oil at electric power plants. Other sources of sulfur dioxide come from industrial facilities that use coal or oil, petroleum refineries, cement manufacturing, metal mining and processing, paper pulp manufacturing and copper smelting. Trains, large ships and some diesel equipment may burn high sulfur fuels which also contributes to sulfur dioxide in the air. Sulfur dioxide has also been used as a food preservative and for food processing; as a disinfectant; for bleaching flour, fruit, grain, wood pulp, wool, textile fibers, wicker, gelatin and glue; and for making other chemicals. It is also used for wastewater treatment. Sulfur dioxide and nitrogen oxides can react with precipitation, oxygen and other substances in the atmosphere to form acid rain. People can be exposed to sulfur dioxide outdoors by breathing polluted air. This is more likely to occur in the summer, when the sun and hot temperatures react with pollution to form smog. Natural pollution sources, such as plant decay and volcanoes can also expose people to this gas. People who live near or work in facilities that utilize sulfur dioxide or produce it as a by-product may also be exposed. According to the U.S. National Library of Medicine, “Breathing sulfur dioxide can irritate the nose, throat, and lungs, and cause coughing and shortness of breath. Short-term exposure to sulfur dioxide can cause stomach pain, menstrual disorders, watery eyes, inhibition of thyroid function, loss of smell, headache, nausea, vomiting, fever, convulsions, and dizziness.” They also report, “Short-term exposure to high levels of sulfur dioxide in the air can be life-threatening by causing breathing difficulties and obstructing airways, especially for people with lung disease. Long-term exposure to persistent levels of sulfur dioxide can cause chronic bronchitis, emphysema, and respiratory illness. It can also aggravate existing heart disease.” These are just a few things to know about sulfur dioxide, exposure risks and potential health concerns.

Antimony - Occupational & Environmental Exposures
 
03:57
Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. The Agency for Toxic Substances & Disease Registry (ATSDR) reports that little antimony is currently mined in the United States, but it is brought into the country from other places for processing. There are also companies that produce antimony as a by-product of smelting lead and other metals. Antimony mixed into alloys is used in such products as lead storage batteries, solder, sheet and pipe metal, bearings, castings and pewter. Antimony oxide is added to textiles and plastics to prevent them from catching fire, and it is also used in paints, ceramics and fireworks, and as enamels for plastics, metal and glass. The ATSDR states that antimony enters the environment during the mining and processing of its ores and in the production of antimony metal, alloys, antimony oxide, and combinations of antimony with other substances. Small amounts of antimony are also released into the environment by incinerators and coal-burning power plants. Antimony can enter the human body when people drink water or eat food, soil or other substances that contain it. Antimony can also enter the body if people breathe contaminated air or dusts. Workers in industries that utilize antimony are at potential risk of exposure to elevated levels. There is an existing occupational airborne exposure limit from OSHA meant to protect workers. The ATSDR reports that exposure to antimony at high levels can result in a variety of adverse health effects. Breathing high levels for a long time can irritate the eyes and lungs and can cause heart and lung problems, stomach pain, diarrhea, vomiting and stomach ulcers. Ingesting large doses can cause vomiting. Long-term animal studies have reported liver damage and blood changes when ingested. Antimony can also irritate the skin if it is left on it. These are just a few things to know about potential occupational and environmental exposures to antimony.

Health Risks Of Heavy Metals
 
21:21
http://www.balancedhealthtoday.com/medicardium.html http://www.balancedhealthtoday.com/store/medicardium.html Where do they come from? Toxic metals can be present in industrial, municipal, and urban runoff, which can be harmful to humans and aquatic life. Increased urbanization and industrialization are to blame for an increased level of trace metals, especially heavy metals, in our waterways. There are over 50 elements that can be classified as heavy metals, 17 of which are considered to be both very toxic and relatively accessible. Toxicity levels depend on the type of metal, it's biological role, and the type of organisms that are exposed to it. The heavy metals linked most often to human poisoning are lead, mercury, arsenic and cadmium. Other heavy metals, including copper, zinc, and chromium, are actually required by the body in small amounts, but can also be toxic in larger doses. Heavy metals in the environment are caused by air emissions from coal-burning plants, smelters, and other industrial facilities; waste incinerators; process wastes from mining and industry; and lead in household plumbing and old house paints. Industry is not totally to blame, as heavy metals can sometimes enter the environment through natural processes. For example, in some parts of the U.S., naturally occurring geologic deposits of arsenic can dissolve into groundwater, potentially resulting in unsafe levels of this heavy metal in drinking water supplies in the area. Once released to the environment, metals can remain for decades or centuries, increasing the likelihood of human exposure. In addition to drinking water, we can be exposed to heavy metals through inhalation of air pollutants, exposure to contaminated soils or industrial waste, or consumption of contaminated food. Because of contaminated water, food sources such as vegetables, grains, fruits, fish and shellfish can also become contaminated by accumulating metals from the very soil and water it grows from. http://www.balancedhealthtoday.com/store http://balancedhealthtoday.com/products.html

In this video, you'll learn how heavy metals from our environment can make us sick and cause cancer. If you want to learn how to avoid cancer, then watch this video. Download our free heavy metal detox guide below. https://goo.gl/oa3Lxu Heavy metals exist naturally on earth. Some metals have essential physiological roles as micronutrients. These include iron, zinc, magnesium, nickel and more. The main threats to human health from heavy metals are from lead, cadmium, mercury, and arsenic. The modern age of heavy metal pollution began with the Industrial Revolution. There was a rapid development of industry, agriculture, and transportation. We started to use it in gasoline, paint, toys, tooth fillings, thermometers, and other things. Heavy metals can diminish your body’s immune system and increase cancer cell production in breast tissues. Aluminum is the third most abundant metal on Earth. It is lightweight, durable and resistant to corrosion.Many electric devices contain aluminum. Aluminum is poisonous if absorbed and can increase the risk of Alzheimer's. Lead is a corrosion-resistant metal. It is detrimental to our health, particularly children. Romans used it since ancient times in their water pipes. Mercury is one of the most toxic substances on earth. When mercury binds to hemoglobin less oxygen reaches the tissues. Therefore mercury and can worsen your cancer condition. Cadmium can cause birth defects and cancer.80% of cadmium production come from nickel-cadmium batteries. It is still used to protect critical parts of airplanes and oil platforms. Arsenic is a well-known poison.It can cause many types of cancer.You can use it as a rat poison and insecticide. Arsenic is part of semiconductors for solid-state devices. Motor vehicle emissions are a major source of airborne contaminants.  Heavy metals associated with transportation include nickel.Zinc and cadmium can come from tires, lubricating oils, and galvanized parts. Around the world, fish absorb toxic mercury from the industrial pollution. Eating even small amounts of fish can have a huge impact on the levels of mercury in our blood. Tobacco kills millions of people every year. Cigarettes can increase the risk of at least 13 other cancers. They are also a great source of heavy metals.Tobacco plants absorb nickel, cadmium and other metals from the soil. They can also contain mercury and arsenic. Batteries consist of many different metals. They leach toxic chemicals into the environment.The leaking material can contaminate the soil and water. So give your used batteries to your recycling center. Vaccines contain toxic chemicals that affect your health. They are not safe for humans. Vaccines can contain mercury or aluminum. Thimerosal, which contains the organic compound ethyl mercury, is a known neurotoxin. Pharmaceutical companies use adjuvants to boost their vaccines. Aluminum salts are the most used adjuvants employed by drug manufacturers. Many of the heavy metals released in the mining and burning of coal affect our environment. The electric power sector is the largest source of toxic pollutants in the United States. Industrial waste leak heavy metals to our groundwater, lakes, streams, and rivers. Under U.S. law, cosmetic products and ingredients, do not need FDA approval before they go on the market. Cosmetic companies do not have to share their product formulations with the FDA. Heavy metals can find its way into in a wide variety of personal care products. Some metals are ingredients, while others are contaminants. Antiperspirants can also contain heavy metals.  Almost all antiperspirants use aluminum or alum-based salts to reduce sweat. Amalgam tooth fillings contain 50% mercury. Heavy metals used in tooth fillings corrode in time when there are air and moisture. The vapor from amalgam can then get into the lungs or your digestive system.  If you have amalgam tooth fillings, then it’s vital that you get rid of them. The term “chemtrails” is a contraction of chemical trails. Chemtrails are geo-engineered aerosols that contain toxic chemicals. They create crisscrossing streaks of white clouds trailing behind jetliners. Chemtrails have nothing to do with the jet engine combustion process. They are a guarded secret by the US government.Water samples of areas affected by chemtrails contain alarming levels of heavy metals. Dangerous metals found are aluminum, strontium, and barium.

Toxic Metals and Mental Health
 
21:21
http://www.balancedhealthtoday.com/medicardium.html http://www.balancedhealthtoday.com/store/medicardium.html The term “heavy metals” refers to elements of specific weight characteristics. Toxic heavy metals are, unfortunately, present in our air, water, soil, and food supply as a byproduct of our industrialized society. In fact, contamination is so pervasive in our environment that it is no longer a question of whether one has been exposed to toxins, but rather the level of exposure. People who have acute toxicity from heavy metals – such as lead, mercury, arsenic, and cadmium – may exhibit obvious and classical symptoms of poisoning. But toxicity from chronic low-level exposure is much more insidious in its presentation. Chronic low-level exposure can lead to a wide array of problems, ranging from neuropsychiatric disturbances such as aggressive behavior, memory loss, depression, irritability, and learning deficits, to physical manifestations such as liver and kidney dysfunction, fatigue, infertility, gout, hypertension, headache, and candida (yeast) infections. Even though efforts are under way to curb the output of toxins and heavy metals into the environment, the problem is far from being resolved. Today, even in the United States, thousands of tons of toxic industrial wastes, including heavy metals, are dumped into the environment every year. We are left with a legacy of years of industrial pollution and toxic substance use that haunts us to this day. Perhaps the two most widespread and significant heavy metal toxins are mercury and lead. Lead It is estimated that about 64 million homes in the United States still contain lead paint and that 5 to 15 million of these have been identified as “very hazardous” by the U.S. Department of Housing and Urban Development. According to the EPA, an estimated 1.7 million children are currently affected by lead toxicity in United States, and almost 900,000 of all children affected are under the age of six. This statistic is very important because the symptoms of lead poisoning in children are strikingly similar to several psychiatric “diseases” that are on the rise in the U.S. Children with high lead levels can exhibit lower IQ scores, learning disabilities, hyperactivity, aggressive or disruptive behavior, and difficulty maintaining attention. A child exhibiting this type of behavior today would likely be sent to a doctor’s office, diagnosed with attention deficit disorder, and promptly started on Ritalin or other psychoactive drugs. Children with high lead levels are much more likely to drop out of school, have reading disabilities, and exhibit criminal behavior. Herbert Needleman, M.D., a professor of psychiatry and pediatrics at the University of Pittsburgh, conducted a study of nearly 2,000 children in Boston. He found that girls with elevated levels of lead were more likely to be dependent, to be poor at concentration, and to “display an inflexible and inappropriate approach to tasks,” while boys were more likely to have difficulty with simple directions and sequences of directions. Dr. Needleman concluded: “…Our findings would appear to add to the weight of evidence that even a lower level of exposure to lead, or its correlates, place children at increased risk of difficulties in school.” It is important to note that childhood exposure to lead can result in adverse effects well into adulthood. A study by Stokes, et al, showed that a group of 281 young adults who had been exposed to lead as children showed significant adverse neurobehavioral effects 20 years after environmental exposure. While lead has been eliminated from the nation’s gasoline supply, the major source of contamination is lead-based paint, which was composed of up to 50% lead. Flakes and microscopic dust from the paint continue to contaminant homes for many years, and can be released in larger amounts during renovations. Additional sources of lead include water pipes, pesticides, factory emissions, cosmetics, and some folk remedies. In addition to being a cellular toxin, lead competes with calcium in the body, which can cause various malfunctions in calcium metabolism including a decrease in neurotransmitter (chemicals that relay messages along nerve cells) release and blockade of calcium channels. The central nervous system appears to be affected to the greatest degree by lead toxicity, and this can explain the many neuropsychiatric symptoms associated with exposure to this heavy metal. Why are some people more susceptible to heavy metal toxicity than others? One must always remember that each individual has a unique physiology, and may have an inherently strong or weak detoxification system to handle heavy metal exposure. In addition, poor nutrition, such as iron or calcium deficiency, has been shown to exacerbate the symptoms of lead exposure. http://www.balancedhealthtoday.com/store http://balancedhealthtoday.com/products.html

Health Risks Of Heavy Metals
 
21:21
http://www.balancedhealthtoday.com http://www.balancedhealthtoday.com/medicardium.html Like heavy metal? Think again. We’re not talking Ozzy here, but in fact heavy metals that can be very harmful to your health if found in your drinking water. Severe effects include reduced growth and development, cancer, organ damage, nervous system damage, and in extreme cases, death. Exposure to some metals, such as mercury and lead, may also cause development of autoimmunity, in which a person's immune system attacks its own cells. This can lead to joint diseases such as rheumatoid arthritis, and diseases of the kidneys, circulatory system, and nervous system. The young are more prone to the toxic effects of heavy metals, as the rapidly developing body systems in the fetus, infants and young children are far more sensitive. Childhood exposure to some metals can result in learning difficulties, memory impairment, damage to the nervous system, and behavioural problems such as aggressiveness and hyperactivity. At higher doses, heavy metals can cause irreversible brain damage. Children may receive higher doses of metals from food than adults, since they consume more food for their body weight than adults. Where do they come from? Toxic metals can be present in industrial, municipal, and urban runoff, which can be harmful to humans and aquatic life. Increased urbanization and industrialization are to blame for an increased level of trace metals, especially heavy metals, in our waterways. There are over 50 elements that can be classified as heavy metals, 17 of which are considered to be both very toxic and relatively accessible. Toxicity levels depend on the type of metal, it's biological role, and the type of organisms that are exposed to it. The heavy metals linked most often to human poisoning are lead, mercury, arsenic and cadmium. Other heavy metals, including copper, zinc, and chromium, are actually required by the body in small amounts, but can also be toxic in larger doses. Heavy metals in the environment are caused by air emissions from coal-burning plants, smelters, and other industrial facilities; waste incinerators; process wastes from mining and industry; and lead in household plumbing and old house paints. Industry is not totally to blame, as heavy metals can sometimes enter the environment through natural processes. For example, in some parts of the U.S., naturally occurring geologic deposits of arsenic can dissolve into groundwater, potentially resulting in unsafe levels of this heavy metal in drinking water supplies in the area. Once released to the environment, metals can remain for decades or centuries, increasing the likelihood of human exposure. http://www.balancedhealthtoday.com/store http://www.balancedhealthtoday.com/store/medicardium.html

Lead Exposure Risks in the Work Environment
 
03:54
The National Institute for Occupational Safety and Health (NIOSH) reports that while many people worry about lead in their homes or in the environment, for some the workplace may offer the greatest potential for exposure. Lead is a toxic heavy metal. It can be combined with other metals to produce alloys. Lead and lead alloys are often used to make batteries, ammunition and other metal products. In the past, lead was also used regularly in fuel, paint, ceramics, caulk, pipes and solder among other things. Due to potential health issues from exposure, the amount of lead used in these products today has lessened or has been removed. Though used less often, NIOSH reports that lead is still common in many industries, including construction, mining and manufacturing. In these and other industries, workers can be at risk of being exposed to lead, by breathing it, ingesting it or coming in contact with it. NIOSH provides the following information for workers about how lead exposure can occur: • Workers can be exposed by breathing-in lead fumes or lead dust. Lead fumes are produced during metal processing, when metal is being heated or soldered. Lead dust is produced when metal is being cut or when lead paint is sanded or removed. Lead fumes and lead dust do not have an odor, so workers may not know they are being exposed. • Lead dust can settle on food, water, clothes and other objects. If a worker eats, drinks or smokes in areas where lead is being processed or stored, they could ingest it. Not washing one’s hands before eating or touching one’s mouth are also ways it could be ingested. • Workers can also be exposed by coming into contact with lead dust. Some studies have found lead can be absorbed through skin. Workers that handle lead and then touch their eyes, nose or mouth, could be exposed. Lead dust can also get on clothes and hair. If this happens, it’s possible that a worker could track home some of the lead dust, which may also expose their family. These are just a few things to know about lead exposure risks in the work environment.

Environmental impact of brown coal and uranium mining in East Germany (Documentary, 1991)
 
50:55
In the aftermath of the collapse of the Soviet Union the world became aware of the devastating impact on the environment and on the health of the people by brown coal and uranium mining in the former East Germany and Czechoslovakia. SAG/SDAG Wismut was a uranium mining company in East Germany during the time of the cold war. It produced a total of 230,400 tonnes of uranium between 1947 and 1990 and made East Germany the fourth largest producer of uranium ore in the world at the time. It was the largest single producer of uranium ore in the entire sphere of control of the USSR. In 1991 after German reunification it was transformed into the Wismut GmbH company, owned by the Federal Republic of Germany, which is now responsible for the restoration and environmental cleanup of the former mining and milling areas. The head office of SDAG Wismut / Wismut GmbH is in Chemnitz-Siegmar. https://en.wikipedia.org/wiki/Wismut_(mining_company) Original title: Black Triangle A film by Ron Orders © 1991, Licensed by Cinecontact Subscribe to wocomoHISTORY: https://goo.gl/oXDoxY Follow us on Facebook: https://www.facebook.com/wocomo

Description 1.Wittenoom,Western Australia Wittenoom is a ghost town 1,106 kilometres (687 mi) north-north-east of Perth in the Hamersley Range in the Pilbara region of Western Australia. The area around Wittenoom was mainly pastoral until the 1930s when mining began in the area. By 1939, major mining had begun in Yampire Gorge, which was subsequently closed in 1943 when mining began in Wittenoom Gorge. In 1947 a company town was built, and by the 1950s it was Pilbara's largest town. During the 1950s and early 1960s Wittenoom was Australia's only supplier of blue asbestos. The town was shut down in 1966 due to unprofitability and growing health concerns from asbestos mining in the area. Today, three[1] residents still live in the town, which receives no government services. In December 2006, the Government of Western Australia announced that the town's official status would be removed, and in June 2007, Jon Ford, the Minister for Regional Development, announced that the townsite had officially been degazetted. The town's name was removed from official maps and road signs and the Shire of Ashburton is able to close roads that lead to contaminated areas. The Wittenoom steering committee met in April 2013 to finalise closure of the town, limit access to the area and raise awareness of the risks. Details of how that would be achieved were to be determined but it would likely necessitate removing the town's remaining residents, converting freehold land to crown land, demolishing houses and closing or rerouting roads. By 2015 six residents remained; in 2016 the number had reduced to three. 2.Kantubek Uzbekistan Kantubek (Russian: Кантубек) was a town on Vozrozhdeniya Island (Uzbekistan) in the Aral Sea. The town is still found on maps, but is uninhabited and lies in ruins today. Kantubek used to have a population of approximately 1,500, and housed scientists and employees of the Soviet Union's top-secret Aralsk-7 biological weapons research and test site. Brian Hayes, a biochemical engineer with the United States Department of Defense's Threat Reduction Agency, led an expedition in the spring and summer of 2002 to neutralize what was believed to be the world's largest anthrax dumping grounds. His team of 113 people neutralized between 100 and 200 tonnes of anthrax over a three-month period. The cost of the cleanup operation was approximately US$5,000,000. 3.Love Canal,Niagara falls Love Canal is a neighborhood within Niagara Falls, New York. It is the site of a pollution disaster that extensively affected the health of hundreds of its residents, necessitating a Superfund cleanup operation. Originally intended in the 1890s as a planned model community, Love Canal grew and then slowly declined before being bought out in the 1940s by the Hooker Company, which dumped industrial waste in the never completed canal. In the late 1970s, Love Canal received national attention for the public health problem originating from the disposal of 22,000 barrels of toxic waste. Numerous families were displaced from their houses, which had been contaminated with chemicals and toxic waste. Many of the families suffered several health issues with common problems of high red blood cell counts and indications of leukemia. The entire neighborhood has since been demolished and a Superfund cleanup was only wrapped up in 2004. New York State Health Department Commissioner David Axelrod calls the Love Canal incident a "national symbol of a failure to exercise a sense of concern for future generations".[1] The Love Canal incident was especially significant as a situation where the inhabitants "overflowed into the wastes instead of the other way around. 4,Picher, Oklahoma Picher is a ghost town and former city in Ottawa County, Oklahoma, United States. This was a major national center of lead and zinc mining at the heart of the Tri-State Mining District. More than a century of unrestricted subsurface excavation dangerously undermined most of Picher's town buildings and left giant piles of toxic metal-contaminated mine tailings (known as chat) heaped throughout the area. The discovery of the cave-in risks, groundwater contamination, and health effects associated with the chat piles and subsurface shafts resulted in the site being included in 1980 in the Tar Creek Superfund Site by the US Environmental Protection Agency. The state collaborated on mitigation and remediation measures, but a 1996 study found that 34% of the children in Picher suffered from lead poisoning due to these environmental effects, which could result in lifelong neurological problems.[4] Eventually the EPA and the state of Oklahoma agreed to a mandatory evacuation and buyout of the entire township. The similarly contaminated satellite towns of Treece, Kansas and Cardin, Oklahoma were included in the Tar Creek Superfund site.

Colorado Mine Spill Closes Animas River

EPA: No Health Risks to Wildlife After Colorado Mine Spill

An Environmental Protection Agency official said Sunday she doesn't believe wildlife will suffer significant health impacts from the large volume of wastewater that spilled from an abandoned mine in southwestern Colorado. The EPA also said the amount of heavy-metal laced wastewater that spilled from Colorado's Gold King Mine into the Animas River, turning the water a mucky orange and then yellow, is three times larger than its initial estimate. The revision came after the EPA used a stream gauge from the U.S. Geological Survey. Four days after the EPA-caused spill, the agency has been unable to determine whether humans or aquatic life face health risks. http://hosted2.ap.org/APDEFAULT/386c25518f464186bf7a2ac026580ce7/Article_2015-08-09-US--Mine%20Waste%20Leak/id-55adb9c7de8649fa8269bb4ad19e13ef http://www.wochit.com This video was produced by Wochit using http://wochit.com

Residents demand health answers as mine spill fouls rivers
 
01:55
YOUR DESCRIPTION HAS REACHED THE LIMIT OF CHARACTERS ALLOWED AND WAS CUT. ALBUQUERQUE, N.M. (AP) -- Farmers, towns and tribes slammed water-intake gates shut as a sludge-laden plume from a Colorado mine spill rolled down principal rivers in the desert Southwest on Monday, prompting local officials and families to demand answers about possible long-term threats from heavy metals borne along by the spill. Colorado and New Mexico declared stretches of the Animas and San Juan rivers to be disaster areas as the orange-colored waste stream estimated to be 100 miles long churned downstream toward Lake Powell in Utah after the spill Wednesday at the abandoned Gold King mine. The Navajo Nation, which covers parts of New Mexico, Utah and Arizona, also declared an emergency as it shut down water intake systems and stopped diverting water from the San Juan River. Members of the tribal council were frustrated during a special meeting Monday and echoed the sentiment of New Mexico officials that the federal government needs to be held accountable. New Mexico Gov. Susana Martinez, who toured the region over the weekend, said she was heartbroken and called the spill a catastrophe. "It's absolutely devastating," she said. The 3 million gallons of mine waste included high concentrations of arsenic, lead and other heavy metals. Workers with the U.S. Environmental Protection Agency accidentally unleashed the spill as federal and contract workers inspected the abandoned mine site near Silverton, Colorado. The EPA has said the contaminants were rolling too fast to be an immediate health threat. Experts and federal environmental officials say they expect the river system to dilute the heavy metals before they pose a longer-term threat. The EPA said stretches of the rivers would be closed for drinking water, recreation and other uses at least through Aug. 17. Dissolved iron in the waste turned the long plume an alarming orange-yellow - a look familiar to old-time miners who call it "yellow boy" - so "the water appears worse aesthetically than it actually is, in terms of health," said Ron Cohen, a civil and environmental engineering professor at the Colorado School of Mines. Tests show some of the metals have settled to the bottom and would dissolve only if conditions became acidic, which isn't likely, Cohen said. The best course for the EPA would be to leave the metals where they settle, he said, noting that next spring's mountain snowmelt would help dilute the contaminants further and flush them downstream. No die-off of wildlife along the river has yet been detected. Federal officials say all but one of a test batch of fingerling trout deliberately exposed to the water survived over the weekend. As a precaution, state and federal officials along the river system have ordered public water systems to turn off intake valves as the plume passes. Boaters and fishing groups have been told to avoid affected stretches of the Animas and San Juan rivers, which are crowded with rafters and anglers in a normal summer. Congress members, state officials and residents contend the EPA is not providing quick answers about long-term impacts from the spill. "There are more people who want to know, "How are we going to protect our families? How long am I not going to be able to shower at my house?" Navajo Council members and New Mexico Environment Secretary Ryan Flynn said the EPA needs to compensate those who have been affected. The state also has demanded that the federal government develop a plan for helping farmers who have been left without irrigation water. In Cedar Hill, New Mexico, a family farm that serves as many as 3,000 customers in the Four Corners region has been forced to stop irrigating dozens of acres of crops. D'rese Sutherland of Sutherland Farmers said she received advanced warning from farmer friends in Colorado last week about the approaching plume. "By the weekend, without any rain, we'll be in trouble," she said. "There's nothing we can do but wait and see what happens." Members of New Mexico's congressional delegation sent a letter to EPA Administrator Gina McCarthy, expressing concern over the failure of the agency to notify New Mexico sooner about the problem. They also asked that the federal agency develop a plan for dealing with the lack of water for communities in San Juan County and the Navajo Nation. The EPA released a statement saying it was sharing information as quickly as possible with the public as its experts evaluate any effects of the spill. It also provided information about its claims process. Recreational businesses along the rivers said they were losing thousands of dollars. "We had lots of trips booked. Right now we're just canceling by the day," said Drew Beezley, co-owner of 4 Corners Whitewater in Durango, Colorado. He

The Impact of Mining on Women
 
19:27
The Marikana massacre most certainly turned the spotlight on the women in mining communities by bringing into sharp focus the challenges facing the widows of the slain mineworkers. Fazila Farouk of SACSIS talks to Samantha Hargreaves of Womin about the broader impact of mining on women in mining communities and learns about land grabs, water grabs and the health impacts of environmental degradation and water pollution, which create an additional burden for the women behind the mineworkers. Women in mining communities, both within sender communities and recipient communities, are often also engaged in unpaid labour that subsidises the profits of big mining companies. The negative impacts of mining well outweigh any social responsibility investments made by mining corporations, contends Hargreaves.

How does Arsenic affect us?
 
04:21
The National Institute of Environmental Health Sciences (NIEHS) funds a Superfund Research Program that aims to support practical research in creating a cleaner and less toxic environment. Dartmouth College Toxic Metals Superfund Research Program Center (Dartmouth SRC) is one of the groups funded by NIEHS. The Dartmouth SRC focuses their studies on human exposure to arsenic and mercury and how these exposures are detrimental to health. The SRP contributed four videos to the Research Replay series, which were made by Sawyer Broadley from the Dartmouth Media Production Group. Postdoctoral researcher, Britton Goodale, PhD, talks about the effects of arsenic in our environment, the effects it can have on the human body, and the research she is doing to help understand them.
