This results in long-term maintenance. Also, most contaminated sites are polluted with many different kinds of contaminants. There can be a combination of metals and organics, in which treatment through rhizofiltration will not suffice. Plants grown on polluted water and soils become a potential threat to human and animal health, and therefore, careful attention must be paid to the harvesting process and only non-fodder crop should be chosen for the rhizofiltration remediation method.

A non-navigable river, the Besòs was nonetheless a link between the Catalan coast and the interior. In the 10th century, the Rec Comtal was built to use the river for irrigation.

However the award went to another company. According to the nomination text, the Russian plant Majak, purchase point for fuel assemblies, is the "most contaminated place on in the world". The Neue Zürcher Zeitung wrote: The fact that environmentalists knew more about the origin than the Axpo specialists is embarrassing.

After 42 years of chemical manufacturing, in 1984, the United States Army began to inspect the level of contamination at Rocky Mountain Arsenal (RMA). The site was placed on the National Priorities List (NPL), a list of the most contaminated areas in the United States. Rocky Mountain Arsenal, among other post-military sites, was a top priority, establishing RMA as a superfund site. This was further exacerbated when the U.S. Army discovered an endangered species, the bald eagle.

United States estimates suggest there are over 500,000 brownfield sites contaminated at levels below the Superfund caliber (the most contaminated) in the country. While historic land use patterns created contaminated sites, the Superfund law has been criticized as creating the brownfield phenomenon where investment moves to greenfields for new development due to severe, no-fault liability schemes and other disincentives. The Clinton-Gore administration and US EPA launched a series of brownfield policies and programs in 1993 to tackle this problem.

The 14 hydroelectric dams on the Columbia's main stem and many more on its tributaries produce more than 44 percent of total US hydroelectric generation. Production of nuclear power has taken place at two sites along the river. Plutonium for nuclear weapons was produced for decades at the Hanford Site, which is now the most contaminated nuclear site in the US. These developments have greatly altered river environments in the watershed, mainly through industrial pollution and barriers to fish migration.

They estimated the Pu-241 dose for a person living for 50 years in the vicinity of the most contaminated site to be 0.44 mSv. However, the Cs-137 activity at the sites where Pu-241 was found was very high (up to 4.7 MBq/kg or about 135,000 times greater than the plutonium 241 activity), which suggests that it will be the Cs-137 which prevents habitation rather than the relatively small amounts of plutonium of any isotope in these areas.

An increased incidence of thyroid cancer was observed for about 4 years after the accident and slowed in 2005.Grimm, E., & University of Colorado Anschutz Medical Campus, degree granting institution. (2015). Thyroid nodules as related to absorbed dose from iodine-131 in a Ukrainian cohort following the Chernobyl accident.

Sewage from Guatemala City has caused the Villalobos and Las Vacas Rivers to be considered the most contaminated streams in the country. Additionally, biological contamination of shallow aquifers by pathogens due to the improper disposal of human or animal wastes is a problem in many populated and rural areas of the country. In agricultural areas, pesticides are a primary source of contamination. Chemical contamination results from the use of fertilizers and pesticides in the sugarcane and banana plantations of the Pacific and Caribbean coastal plains.

In 1954, the fallout plume from the Castle Bravo nuclear test passed over Bikar about 20 hours after the shot. Based on ash from plant samples taken on March 9, the atoll was contaminated by about 1,400,000 d/m/gm of radioactive material, compared with 35,000,000 d/m/gm from the most contaminated soil samples at Rongelap Atoll, and 950 d/m/gm at Majuro Atoll, several hundred miles south of the fallout pattern.

A mix-up rated as contamination could in reality be a simple confusion of two cell lines, but usually contamination is assumed. After a cell line has been discovered to be contaminated, they are usually never used again for research demanding the specific type of cell line they are assumed to be. Most contaminated cell lines are discarded, however sometimes contaminant cells have acquired novel characteristics (e.g., by mutation or viral transfection, for example the HeLa derivate Det98) and thus constitute a novel lineage after all, so are not thrown away.

The robot which disassembled the most contaminated parts of the facility in action A group of NUMEC employees discovered that irradiating hardwood treated with plastics produced very durable flooring. In 1978 they formed PermaGrain Products, Inc. as a separate company from ARCO, and purchased the rights to the process as well as "the main irradiator, a smaller shielded irradiator and related equipment". PermaGrain sold the flooring for use in basketball courts and gymnasiums, and was the longest occupant of the Quehanna facility, operating there from 1978 to December 2002.

However, the region near Chelyabinsk was and is much more sparsely populated than the region around Chernobyl. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) has conducted 20 years of detailed scientific and epidemiological research on the effects of the Chernobyl accident. Apart from the 57 direct deaths in the accident itself, UNSCEAR predicted in 2005 that up to 4,000 additional cancer deaths related to the accident would appear "among the 600 000 persons receiving more significant exposures (liquidators working in 1986–87, evacuees, and residents of the most contaminated areas)".

The Board of Health in London had several committees, of which the Committee for Scientific Inquiries was placed in charge of investigating the cholera outbreak. They were to study the atmospheric environment in London; however, they were also to examine samples of water from several water companies in London. The committee found that the most contaminated water supply came from the South London water companies, Southwark and Vauxhall. As part of the Committee for Scientific Inquiries, Richard Dundas Thomson and Arthur Hill Hassall examined what Thomson referred to as "vibriones".

As the attorney general of Oklahoma, Trump's choice of EPA administrator Scott Pruitt challenged EPA regulations in court more than a dozen times. With some cases still pending, Pruitt declined to say if he would recuse himself with regard to those suits. Pruitt hired former Oklahoma banker Albert Kelly to head the Superfund program, which is responsible for cleaning up the nation's most contaminated land. Kelly completely lacked any experience with environmental issues, and had just received a lifetime ban from working in banking, his career until then, due to "unfitness to serve".

The Tárcoles River, also called the Grande de Tárcoles River or the Río Grande de Tarcoles, in Costa Rica originates on the southern slopes of the Cordillera Central volcanic range and flows in a south-westerly direction to the Gulf of Nicoya. The river is long and its watershed covers an area of , which encompasses around 50% of the country's population. The river's watershed drains approximately 67% of Costa Rica's untreated organic and industrial waste and is considered the most contaminated river basin in the country. The river's upper reaches form the northern border of the Carara Biological Reserve.

Hanford Nuclear Reservation is currently the most contaminated nuclear site in the United States and is the focus of the nation's largest environmental cleanup. The radioactive materials are known to be leaking from Hanford into the environment. In 2007, Washington became the first state in the nation to target all forms of highly toxic brominated flame retardants known as PBDEs for elimination from the many common household products in which they are used. A 2004 study of 40 mothers from Oregon, Washington, British Columbia, and Montana found PBDEs in the breast milk of every woman tested.

South Prescott is a hundred year old neighborhood in West Oakland; due to past industrial activity and leaded gas neighborhood soil averaged 800 ppm lead before a major EPA-led cleanup. Some of the most contaminated areas of the neighborhood had soil lead levels in excess of 2700 ppm. The EPA-led cleanup used ground up bones from pollock to convert elemental lead in the soil to pyromorphite, a compound that is harmless even if it is ingested. The cleanup successfully remediated around 95% of residential properties in South Prescott, as well as all public right- of-ways.

The Matanza-Riachuelo river (MR), a tributary of the Río de la Plata (La Plata River), is the most contaminated river basin in Argentina and considered one of the most polluted water bodies in the world. Pollution levels in Buenos Aires’ rivers are so high that they have been considered “open sewers”, making pollution the greatest environmental risk for the metropolitan area. Pollution levels have increased steadily as urbanization and industrial growth have continuously increased in the metropolitan area of Buenos Aires. It is estimated that more than 4,000 industrial facilities are located in the lower and middle sections of the basin.

Polar bears accumulate high levels of persistent organic pollutants such as polychlorinated biphenyl (PCBs) and chlorinated pesticides. Due to their position at the top of the ecological pyramid, with a diet heavy in blubber in which halocarbons concentrate, their bodies are among the most contaminated of Arctic mammals. Halocarbons (also known as organohalogens) are known to be toxic to other animals, because they mimic hormone chemistry, and biomarkers such as immunoglobulin G and retinol suggest similar effects on polar bears. PCBs have received the most study, and they have been associated with birth defects and immune system deficiency.

Newtown Creek, a a long estuary that forms part of the border between the boroughs of Brooklyn and Queens, has been designated a Superfund site for environmental clean-up and remediation of the waterway's recreational and economic resources for many communities. One of the most heavily used bodies of water in the Port of New York and New Jersey, it had been one of the most contaminated industrial sites in the country, containing years of discarded toxins, an estimated of spilled oil, including the Greenpoint oil spill, raw sewage from New York City's sewer system, and other accumulation.

In the 1980s 40% of the lambs in Canterbury, a region with low rainfall and occasional droughts, had DDT levels that were above the European Union's permitted limit but still acceptable under safe tolerance limits for New Zealand. Mapua was one of the most contaminated sites in New Zealand due to pesticide residues in the soils from a now defunct factory. In the 1940s organomercury and organochlorine pesticides, including DDT, DDD, dieldrin, 2,4-D and paraquat, were produced. The factory closed in 1988 and the site was subjected to a major cleanup operation in the 2000s.

James L. Acord in front of the Fast Flux Test Facility, Hanford Site, WA, USA. James Leroy Acord (19 October 1944 – 9 January 2011) was an artist who worked directly with radioactive materials. He attempted to create sculpture and events that probed the history of nuclear engineering and asked questions about the long-term storage of nuclear waste. For 15 years he lived in Richland, Washington, the dormitory town for the Hanford Nuclear Reservation, at one time home to nine nuclear reactors and five plutonium-processing complexes and the most contaminated nuclear site in the United States.

UNSCEAR has conducted 20 years of detailed scientific and epidemiological research on the effects of the Chernobyl accident. Apart from the 57 direct deaths in the accident itself, UNSCEAR predicted in 2005 that up to 4,000 additional cancer deaths related to the accident would appear "among the 600 000 persons receiving more significant exposures (liquidators working in 1986–87, evacuees, and residents of the most contaminated areas)". Russia, Ukraine, and Belarus have been burdened with the continuing and substantial decontamination and health care costs of the Chernobyl disaster. Eleven of Russia's reactors are of the RBMK 1000 type, similar to the one at Chernobyl Nuclear Power Plant.

Full Body Burden: Growing Up in the Nuclear Shadow of Rocky Flats is a 2012 memoir fusing Iversen's personal story of growing up in Cold War America with the history of the former Rocky Flats Nuclear Plant near Denver, Colorado, once called by the Department of Energy “the most contaminated site in America.” From 1952 to 1989 there were many fires, leaks, and other mishaps at Rocky Flats. The area became severely contaminated, and little attention was paid to containment and environmental remediation. Carl J. Johnson, director of health between 1973 and 1981, led research into contamination levels and adverse effects on public health, until his employment was terminated.

The Red Forest (Ukrainian: Рудий ліс, Rudyi lis Russian: Рыжий лес Ryzhy les, literally "ginger-color forest") is the 10-square-kilometer (4 sq mi) area surrounding the Chernobyl Nuclear Power Plant within the Exclusion Zone located in Polesia. The name "Red Forest" comes from the ginger-brown color of the pine trees after they died following the absorption of high levels of radiation from the Chernobyl accident on 26 April 1986. In the post-disaster cleanup operations, the Red Forest was bulldozed and buried in "waste graveyards". The site of the Red Forest remains one of the most contaminated areas in the world today.

A number of techniques are being considered that will be able to strip out 80% to 95% of the caesium from contaminated soil and other materials efficiently and without destroying the organic material in the soil. These include hydrothermal blasting. The caesium precipitated with ferric ferrocyanide (Prussian blue) would be the only waste requiring special burial sites. The aim is to get annual exposure from the contaminated environment down to 1 mSv above background. The most contaminated area where radiation doses are greater than 50 mSv/year must remain off limits, but some areas that are currently less than 5 mSv/year may be decontaminated, allowing 22,000 residents to return.

Between 1999 and 2001 benthic toxicity tests found PAHs and mercury levels at up to 507 mg/kg and 13 mg/kg respectively at this site and a portion was designated as an area of concern (AOC). The most contaminated, AOC is adjacent to the former wastewater outfall which has been relocated into San Pablo Bay. A California Environmental Quality Act (CEQA)-mandated mitigated negative declaration was completed and a corrective action plan was designed. The plan which includes a natural resource damage assessment will cordon off the AOC with steel sheet piling and have the contaminated muds and sediment dredged and pumped into a disused treatment pond.

In attempts to lift regulations on oil, mining, drilling, and farming industries, the Trump administration proposed a 31% budget cut to the EPA that would result in reduced initiatives to protect water and air quality, leaving much of the effort up to the states. Environmentalists fear that these cuts will result in health problems. EPA budget cuts are also expected to lead to decreased regulation of hydraulic fracturing (fracking), which would result in less federal oversight of clean- up projects in these areas. EPA administrator Scott Pruitt hired former Oklahoma banker Albert Kelly to head the Superfund program, which is responsible for cleaning up the nation's most contaminated land.

The disaster site was so heavily contaminated with benzene that firefighters and investigators in the first month worked in fifteen-minute shifts due to heat and toxic conditions. The waterfront at Veteran's Park and the town marina were contaminated by hydrocarbons, which were contained by a series of booms. This rendered vessels and docks inaccessible until they can be removed from the water and decontaminated, a process which was to take until late August 2013 to complete. A hundred residents were not expected to return home until mid-2014 as the ground beneath their still-standing houses was contaminated with oil; some homes in the most-contaminated areas might never be habitable.

Hanford workers The Hanford Nuclear Reservation (HNR), also known as the Hanford Site, located in Washington State in the western United States adjacent to the Columbia River, is a nuclear materials production complex that is in the process of being decommissioned. HNR was founded in 1943 as part of the Manhattan Project for large-scale production of plutonium for use in nuclear weapons, including the first nuclear bomb tested at the Trinity site in New Mexico, and the Fat Man nuclear bomb used at Nagasaki, Japan, during WWII. Hanford is considered the most contaminated nuclear waste site America. Much of the clean-up has focused on water and land contamination from leaking tanks, as well as airborne radioactive dusts.

Lawrence Aviation Industries, Inc. (Lawrence Aviation) was an aircraft parts manufacturer which made titanium parts for military aircraft, such as the Grumman F-14 fighter jet. The former owner of the company, Gerald Cohen, was sentenced to one year and a day in prison and ordered to pay $105,816 in restitution for illegal storage of more than 12 tons of hazardous waste on the company's grounds. The abandoned remains of the company, located is off Sheep Pasture Road in the hamlet of Port Jefferson Station, Town of Brookhaven, New York is now one of the most contaminated sites on Long Island and may be responsible for a toxic groundwater plume in the region.

The Almendares River, the main river flowing through the city of Havana, is the most contaminated river in the western hemisphere. It is dead, with no animal life History: The Cuban aborigines called it Casiguaguas, and the first colonizers named it La Chorrera, when it was discovered, until they changed it to Almendares in honor of the Bishop of Havana, Enrique Almendaris. The first aqueduct that was built for the city of Havana took its waters directly from the Almendares River, and it became known as "Zanja Real" -1545-. Over the years, this ditch began to be insufficient and stopped working, giving way to the project of Francisco de Albear y Lara, the largest Aqueduct in the city built in 1859 - 1897.

From 1949 to 1956 the Mayak complexTecha River dumped an estimated of radioactive waste water into the Techa River,CHELYABINSK "The Most Contaminated Spot on the Planet" - a documentary film by Slawomir Grunberg - Log In Productions - distributed by LogTV LTD a cumulative dispersal of of radioactivity. As many as forty villages, with a combined population of about 28,000 residents, lined the river at the time.Radioactive Contamination of the Techa River and its Effects For 24 of them, the Techa was a major source of water; 23 of them were eventually evacuated. In the past 45 years, about half a million people in the region have been irradiated in one or more of the incidents, exposing them to as much as 20 times the radiation suffered by the Chernobyl disaster victims.

It would be the only component of the waste requiring special burial sites.Dennis Normile, "Cooling a Hot Zone," Science, 339 (1 March 2013) pp. 1028–1029. The aim is to get annual exposure from the contaminated environment down to one millisievert (mSv) above background. The most contaminated area where radiation doses are greater than 50 mSv/year must remain off limits, but some areas that are currently less than 5 mSv/year may be decontaminated allowing 22,000 residents to return. To help with protection of people living in geographical areas which have been radioactively contaminated the International Commission on Radiological Protection has published a guide: "Publication 111 – Application of the Commission’s Recommendations to the Protection of People Living in Long-term Contaminated Areas after a Nuclear Accident or a Radiation Emergency".

Intermittent discoveries of undocumented contamination have slowed the pace and raised the cost of cleanup. In 2007, the Hanford site represented 60% of high-level radioactive waste by volume managed by the US Department of Energy and 7–9% of all nuclear waste in the United States (the DOE manages 15% of nuclear waste in the US, with the remaining 85% being commercial spent nuclear fuel). Hanford is currently the most contaminated nuclear site in the United States and is the focus of the nation's largest environmental cleanup. Besides the cleanup project, Hanford also hosts a commercial nuclear power plant, the Columbia Generating Station, and various centers for scientific research and development, such as the Pacific Northwest National Laboratory, the Fast Flux Test Facility and the LIGO Hanford Observatory.

Across Europe the Chernobyl-incident had likewise effects on wild fauna and flora. The first study of the effects of radioactive contamination following the Fukushima Daiichi nuclear disaster suggested, through standard point count censuses that the abundance of birds was negatively correlated with radioactive contamination, and that among the 14 species in common between the Fukushima and the Chernobyl regions, the decline in abundance was presently steeper in Fukushima. However criticism of this conclusion is that naturally there would be less bird species living on a smaller amount of land, that is, in the most contaminated areas, than the number one would find living in a larger body of land, that is, in the broader area. Scientists in Alaska are testing seals struck with an unknown illness to see if it is connected to radiation from Fukushima.

The government had to declare an environmental state of emergency at several mining sites due to environmental disasters. For example, in July 2008 it declared a state of emergency at a mine near Lima over fears that arsenic, lead and cadmium from its tailings dam could pollute the main water supply for the capital. In July 2010 the government declared another state of environmental emergency in the central mining district of Huancavelica after a wastewater storage dam of the Caudalosa Chica company collapsed and leaked water laden with heavy metals into local rivers.Earth Times: Peru declares environmental emergency over mine waste water, July 7, 2010 The city La Oroya on the Mantaro River in Central Peru where the company Doe Run operates a big mining complex has been ranked as one of the 10 most contaminated cities in the world in 2007.

Efforts have been made to control the major tributaries of Río de la Plata such as channelizing and building culverts into urban rivers, however, this has increased flooding as the natural meander and saturating ability of the rivers have been lost. Rapid urbanization and very large quantities of industrial discharge have also caused severe contamination of the water basins that Buenos Aires is built upon. The Matanza-Riachuelo river (MR), a tributary of the Río de la Plata (La Plata River), is a prime example and has become the most contaminated basin in Argentina. In response to water pollution and flooding challenges, the Government of Argentina (GoA) is working with the World Bank to address industrial water pollution by providing technical assistance and mentoring to the 50 worst industrial polluters which represent 95% of the total effluent.

After the 1957 accident, dumping in the Techa River officially ceased, but the waste material was dumped in convenient shallow lakes near the plant instead, of which 7 have been officially identified. Of particular concern is Lake Karachay, the closest lake to the plant (now notorious as the most contaminated place on EarthLenssen, "Nuclear Waste: The Problem that Won't Go Away", Worldwatch Institute, Washington, D.C., 1991: 15.) where roughly 4.4 exabecquerels of high-level liquid waste (75-90% of the total radioactivity released by Chernobyl) was dumped and concentrated in the shallow lake over several decades. In addition to the radioactive risks, the airborne lead and particulate soot levels in Ozyorsk (along with much of the Ural industrial region) are also very high—roughly equal to the levels encountered along busy roadsides in the era predating unleaded gasoline and catalytic converters—due to the presence of numerous lead smelters.

The compensation of the two staffers was substantially higher than the salaries of staff in similar positions in the Obama administration. The method of raising their pay also allowed both to avoid signing ethics pledges meant to deter conflicts of interest, an issue raised by Democratic Senators Tom Carper and Sheldon Whitehouse for consideration of an investigation. While Pruitt claimed in an April 4, 2018 televised interview with Fox News correspondent Ed Henry that he didn't know anything about the raises to his two close aides, the Washington Post reported on April 5, 2018 that two EPA officials and a White House official told The Post that Pruitt instructed staff to award substantial pay boosts to both women, who had worked in different roles for him in Oklahoma. Pruitt hired former Oklahoma banker Albert Kelly to head the Superfund program, which is responsible for cleaning up the nation's most contaminated land.

On 30 September 2011, the Japanese Ministry of Education and Science published the results of a plutonium fallout survey, for which in June and July 50 soil samples were collected from a radius of slightly more than 80 km around the Fukushima Daiichi plant. Plutonium was found in all samples, which is to be expected since plutonium from the nuclear weapon tests of the 1950s and '60s is found everywhere on the planet. The highest levels found (of Pu-239 and Pu-240 combined) were 15 becquerels per square meters in Fukushima prefecture and 9.4 Bq in Ibaraki prefecture, compared to a global average of 0.4 to 3.7 Bq/kg from atomic bomb tests. Earlier in June, university researchers detected smaller amounts of plutonium in soil outside the plant after they collected samples during filming by NHK. A recent study published in Nature found up to 35 bq/kg plutonium 241 in leaf litter in 3 out of 19 sites in the most contaminated zone in Fukushima.

The BIPM's FAQ explains, for example, that the divergence is dependent on the amount of time elapsed between measurements and not dependent on the number of times the prototype or its copies have been cleaned or possible changes in gravity or environment. Reports published in 2013 by Peter Cumpson of Newcastle University based on the X-ray photoelectron spectroscopy of samples that were stored alongside various prototype kilograms suggested that one source of the divergence between the various prototypes could be traced to mercury that had been absorbed by the prototypes being in the proximity of mercury-based instruments. The IPK has been stored within centimetres of a mercury thermometer since at least as far back as the late 1980s. In this Newcastle University work six platinum weights made in the nineteenth century were all found to have mercury at the surface, the most contaminated of which had the equivalent of 250μg of mercury when scaled to the surface area of a kilogram prototype.

After a pipe burst at the company's Waldwick, New Jersey facilities, 33,000 gallons of chemicals contaminated the soil and groundwater at the site. Together with his employees, Snyder developed a technique to pump magnesium, nitrogen and other nutrients into the soil to help bacteria naturally present underground to digest the pollutants – which included benzene, methylene chloride, toluene and xylene – with carbon dioxide and water as the main byproducts, using a small pump house, two tanks and a network of pipes under the ground to implement the process. In the early 1980s, Snyder reported that the process had been used to successfully treat a soil sample from the Lipari landfill in Bridgeport, New Jersey, one of the state's most contaminated sites, and had been unofficially approved by the New Jersey Department of Environmental Protection for use at the Biocraft spill. Snyder estimated that the new method had purified five million gallons of contaminated water in three years at a cost of $80,000 compared to more than $2 million for traditional methods which would have taken years more to complete.

Although people in the incident's worst affected areas have a slightly higher risk of developing certain cancers such as leukemia, solid cancers, thyroid cancer, and breast cancer, very few cancers would be expected as a result of accumulated radiation exposures. Estimated effective doses outside Japan are considered to be below (or far below) the levels regarded as very small by the international radiological protection community. In 2013, the World Health Organization reported that area residents who were evacuated were exposed to so little radiation that radiation-induced health effects were likely to be below detectable levels. The health risks were calculated by applying conservative assumptions, including the conservative linear no- threshold model of radiation exposure, a model that assumes even the smallest amount of radiation exposure will cause a negative health effect. The report indicated that for those infants in the most affected areas, lifetime cancer risk would increase by about 1%. It predicted that populations in the most contaminated areas faced a 70% higher relative risk of developing thyroid cancer for females exposed as infants, and a 7% higher relative risk of leukemia in males exposed as infants and a 6% higher relative risk of breast cancer in females exposed as infants.

Rather than cease production of plutonium until new underground waste storage tanks could be built, between 1949 and 1951 Soviet managers dumped 76 million cubic meters of toxic chemicals including 3.2 million curies of high-level radioactive waste into the Techa River, a slow- moving hydraulic system that bogs down in swamps and lakes. As many as forty villages, with a combined population of about 28,000 residents, lined the river at the time.Radioactive Contamination of the Techa River and its Effects For 24 of them, the Techa was a major source of water; 23 of them were eventually evacuated. In the 45 years afterwards, about half a million people in the region have been irradiated in one or more of the incidents, exposing them to up to 20 times the radiation suffered by the Chernobyl disaster victims outside of the plant itself.CHELYABINSK "The Most Contaminated Spot on the Planet" - a documentary film by Slawomir Grunberg - Log In Productions - distributed by LogTV LTD Investigators in 1951 found communities along the river highly contaminated. On discovery, soldiers immediately evacuated the first downriver village of Metlino, population 1,200, where radiation levels measured 3.5–5 rads/hr (35–50 mGy/hr or 10–14 μGy/s).
