Indian Point nuclear facility operator reports ‘alarming levels’ of radioactivity in plant’s groundwater; some wells increase 65,000% New York Daily News, BY DENIS SLATTERY NEW YORK DAILY NEWS, February 7, 2016,
Radioactive water overflowed into the groundwater at the upstate Indian Point nuclear power plant, officials said Saturday.
Gov. Cuomo said the plant’s operator, Entergy, reported “alarming levels” of radioactivity at three monitoring wells, with one well’s radioactivity increasing nearly 65,000%………
The site, roughly 35 miles north of New York City, has been under increased scrutiny from Cuomo and other officials following several incidents. In December, Cuomo ordered an investigation into Indian Point after a series of unplanned shutdowns, citing potential risks to both the city and surrounding suburbs.
Cuomo said the “latest failure at Indian Point is unacceptable.”
According to Neil Sheehan, a spokesman for the Nuclear Regulatory Commission, the leak occurred after a drain overflowed during a maintenance exercise while workers were transferring water containing high levels of radioactive contamination.
A sump pump that would normally filter the water into another treatment system was out of service, Sheehan said.
Other state officials also blasted the controversial nuclear facility’s most recent mishap.
Assemblywoman Ellen Jaffee (D-Suffern)said she was concerned not only for the surrounding community but also for the “impact this radioactive water may have on public health and our environment,” Jaffee added…….http://www.nydailynews.com/new-york/radioactive-water-leaks-groundwater-indian-point-article-1.2522670
NRA’s data shows contamination level in Tokyo tap water higher than Fukushima by 24 percent http://fukushima-diary.com/2016/01/nras-data-shows-contamination-level-in-tokyo-tap-water-higher-than-fukushima-by-24-percent/ Iori Mochizuki According to NRA (Nuclear Regulation Authority), Cs-134/137 density in Tokyo tap water is 24% higher than Fukushima.
The report was released on 10/30/2015, titled as “Readings of radioactivity level in drinking water by prefecture” to cover from July to September in 2015.
From this report, only 0.0015 Bq/Kg of Cs-137 was detected in Fukushima drinking water. Cs-134 was not supposed to be detected. On the other hand, 0.00036 Bq/Kg of Cs-134 and 0.0015 of Bq/Kg were detected from Tokyo drinking water.
The measurement of Cs-134 is due to Fukushima accident.
NRA comments each data is based on the reports from prefectures.
It is not mentioned by Fukushima prefectural government why Cs-134 was not detected in their drinking water.
Uranium Mining Threatens the Karoo, Karoo Space, 18 Jan 16 By Dr Stefan Cramer Images sourced by Dr Stefan Cramer “…..According to its documents, Tasman RSA Mines today controls exclusive prospecting rights over more than 750 000 hectares in a circle of nearly 200 kilometres around Beaufort West.
About 32 000 hectares are directly owned under freehold by the company. Local farmers find it hard to resist purchase offers, as farming in this part of the Karoo is particularly difficult due to low rainfall and poor soils.
Unlike in fracking, farms are permanently damaged by uranium opencast mining………
So far the company has not indicated whether they would use ‘in-situ-leaching’, a particularly dangerous but low-cost method. Here, large quantities of leaching agent are injected underground. The uranium is dissolved and recovered in well fields.
The uranium deposits are scattered over large zone of 200 by 300 kilometres which will necessitate trucking of ores over poorly constructed dust roads for hundreds of kilometres to reach the Central Processing Plant.
For this plant, the company has already applied for a water licence to abstract annually 700 million litres of groundwater annually, roughly half of the total water consumption of the Central Karoo Municipality.
It is still unclear what will happen with the contaminated waste water. A discharge of radioactive waste water into the aquatic environment, above or below ground, would be illegal under South Africa’s strict Water Act.
Most probably contaminated slimes will be delivered to large settling ponds, like those around Johannesburg, from which the remaining water will evaporate. This leaves behind a soft and unstable pile of contaminated soil which can be easily mobilised by the strong prevailing winds in the Karoo into large dust dispersal.
Already today, the environment around Beaufort West is contaminated close to the previous mine sites. First field studies by the author show unprotected nuclear wastes with 10 to 20 times the background radiation.
Dust and Radiation – Two Deadly Impacts
The devastating impacts of uranium mining on people, especially the mine workers, and the environment have been well research and documented. Several studies of large number of cases and with exposure over many years (Wismut AG in the former East Germany, theColorado-Plateau in the USA, and Saskatchewan in Canada, have established a particular direct relationship between occupational exposure to uranium and its decay products and lung diseases.
Mining uranium ore in the Karoo will invariably create huge plumes of contaminated dust. Dust clouds are unavoidable during drilling, blasting and transporting.
Dust suppression by spraying water is only partially effective and creates new problems with contaminated slimes, adding to the environmental cost of groundwater abstraction……..http://karoospace.co.za/uranium-mining-threatens-the-karoo/
Nevada says national nuclear dump could harm farm community,Naples
Herald, By Associated PressNov 23, 2015 BY KEN RITTER LAS VEGAS (AP) — Radioactive well-water contamination could threaten some 1,400 people in a rural farming community if federal regulators allow the nation’s deadliest nuclear waste to be buried in the Nevada desert, state officials said in a report issued Friday.
A 53-page document submitted to the U.S. Nuclear Regulatory Commission derides environmental assessments of the proposed Yucca Mountain repository as legally inadequate. It also characterizes the project itself as “an unworkable waste management plan at an unsafe repository site.”
“In the end, there are real people there,” said Robert Halstead, chief of the Nevada Agency for Nuclear Projects and the top state official leading opposition to the project.
“That’s the thing about the way the NRC has approached the whole process,” Halstead said Friday. “Their maps imply there is no population there. They label it as the Amargosa desert.”
George Gholson, chairman of the Timbisha Shoshone Tribe, submitted additional comments Friday accusing commission officials of failing to evaluate effects that building the project would have on tribal members.
“Radioactive contamination of groundwater and springs … affronts the Timbisha’s way of life, is disrespectful to cultural beliefs, and constitutes an environmental justice infringement on the rights of a sovereign nation,” the letter said.
The documents amount to the state staking its legal ground to oppose the Yucca Mountain project. They came on the last day of an environmental study comment period ahead of yet-to-be-scheduled licensing hearings and amid calls from some in Congress to restart the long-mothballed project.
Commission officials didn’t immediately respond to messages seeking comment.
More than three decades of study yielded findings that water seeping through tunnels containing some 77,000 tons of spent nuclear reactor waste could become contaminated and slowly migrate into groundwater west along the normally dry course of the ancient Amargosa River, toward Death Valley in California……..
A federal appeals court breathed new life into the project in 2013 with an order that the Nuclear Regulatory Commission either approve or reject the Energy Department license application.
Officials say a full slate of licensing hearings could take at least three years. http://naplesherald.com/2015/11/23/nevada-says-national-nuclear-dump-could-harm-farm-community/
Huffington Post, 24 Nov 15, [Good maps] “…….The mining industry’s statement counts on readers to be ignorant of the fact that federal and state agencies do not require wells to measure water pollution more than a thousand feet underground, where uranium mining threatens aquifers that feed springs deep within the Grand Canyon. No monitoring means contamination is undetected: out of sight, out of mind.
But that’s changing as the U.S. Geological Survey pieces together samples taken from existing wells and places where groundwater flows downward into the Grand Canyon. These show that mining has already polluted 15 springs and five wells within the Grand Canyon’s watershed with toxic levels of uranium.
As I’ve said with regards to oil and gas development, one well contaminated or one person made sick is one too many. The same is true for uranium mining, making the situation around the Grand Canyon a disaster where we can least afford one.
In 2012, this sorry history led my friend and fellow Coloradan, Interior Secretary Ken Salazar, to impose a 20-year ban on new uranium mining in the watersheds that drain directly into the Grand Canyon. His action came in response to thousands of new mining claims filed in the preceding decade. Science and prudence also guided his decision, coupled with the knowledge that nearly $1 billion in annual economic activity is generated by this greatest of earth’s geological treasures.
Need for Permanent Ban on Grand Canyon Uranium Mining
The bill aims to protect 1.7 million acres of historical tribal homeland, including water sources and sacred sites.
Unfortunately, there’s almost no chance that the legislation will gain approval in today’s gridlocked Congress. But the 1906 Antiquities Act gives the president unilateral authority to set aside federal lands as protected national monuments to stop the looting of archaeological sites and for reasons of “historic or scientific interest.”
I’ve long believed we will be judged by the nation we leave to future generations. After all, we don’t inherit the earth from our parents — we borrow it from our children. The president should act now to protect the Grand Canyon from irresponsible development around this national treasure.
The National Mining Association may not be willing to stop digging — literally or figuratively — but the president owes it to us all to help them.
The first of its two operating licenses from the federal government expires in 2024, the second a year later. Federal regulators are weighing whether to renew those licenses and keep Diablo humming through 2045. PG&E, however, appears to be having second thoughts.
And any extension will involve a fight. The plant sits within a maze of earthquake faults, all of them discovered after construction began in 1968. Seismic safety fears have dogged the nuclear industry in California for more than 50 years, forcing PG&E to abandon plans for one of its first reactors…… Continue reading
Why Are We Allowing Uranium Miners to Pollute Groundwater in Drought Zones?
Uranium mining threatens aquifers that could provide the drought-stricken West with emergency water supplies. BRIAN PALMER OCT 16, 2015 Mining uranium, the fuel for nuclear reactors, is a dirty business. Following World War II, mining companies extracted millions of tons of uranium from Navajo tribal lands in the West, contaminating homes and water supplies in the process. It went on for decades, and Navajo miners developed lung cancer at very high rates.
Today, even as the United States nuclear power industry struggles to survive, uranium mining continues. The techniques are more modern, but conservationists say the threat could be just as insidious: polluting water supplies in drought-ridden parts of the country where drinking water is already alarmingly scarce.
New rules proposed by the federal government last year could help reduce the threat—although industry is fighting to weaken them, along with its Republican allies in Congress. And critics say the proposed regulations might not be strong enough anyhow. Ironically, this might all be happening to extract a resource we barely need anymore—at the risk of one that we most certainly do……..
The industry must now work with what geologists call “roll-fronts.” These are relatively thin uranium deposits that formed deep underground over the course of thousands of years. Typically just 10 to 30 feet in height—too small to be harvested by human miners—the roll-fronts can only be extracted by chemical means.
The process used today is called in situ recovery, or ISR, mining. (Opponents use the more chemically descriptive phrase “in situ leaching,” or ISL.) The mining company drills four or five holes, called injection wells, and then pumps down a mix of an oxidizing agent (often hydrogen peroxide or simple oxygen) and water. Pressure from the constant influx of fluid forces the solution to percolate through the uranium-rich layer of Earth toward another hole, called the production well, which carries it up to the surface. At this point, the company reverses the chemical reaction that dissolved the uranium, using a separate chemical to precipitate the metal out of the water. The water, now stripped of most of the uranium, heads back into the well to continue the cycle…….
In reality, ISR mining isn’t so tidy, and the few peer-reviewed studies available suggest that leaching uranium out of rocks contaminates the surrounding groundwater for decades. As Western states deal with increasing levels of drought, that’s a problem…….
Remediation is water- and time-intensive, but does it work? The answer is pretty disturbing: No one knows. There have been only a handful of major studies on the efficacy of the uranium-mining remediation process. Continue reading
MP warning over new nuclear power station in Essex East Anglian Daily Times 25 September 2015 Matt Stott An Essex MP has claimed a new nuclear power station at Bradwell would cause “significant damage” to the marine environment. Harwich and North Essex MP Bernard Jenkin expressed concern over the impact the site would have on the region’s fishing industries and ecology.
His intervention comes days after Chancellor George Osborne indicated a £2 billion Government guarantee for Chinese investment in the proposed Hinkley Point C nuclear power plant in Somerset could pave the way for further deals, including a majority Chinese-owned nuclear generation facility at Bradwell.
It is thought the site, next to the former nuclear power station, could be shared with between owners EDF and Chinese firms to build and run a new nuclear plant.
Mr Jenkin said: “There should be no new nuclear at Bradwell, unless the concerns about damage to the estuary and storage of nuclear waste on site can both be unequivocally resolved. “There seems no way that a new nuclear power station would avoid significant damage to the marine environment in the estuary.
“When the Magnox station was decommissioned, there was explosive recovery in the marine environment. I have been informed that a new power station would take six times more flow of water than its predecessor.
“The estuary cannot supply the volume of cooling water without severely damaging the natural life-cycle of organisms in it. This jeopardises the ecology, our local fishing industries and goes against the aim of the Marine Conservation Zone.”
He added: “It is also a significant concern… that high level nuclear waste would have to be secured and stored on the site for some decades after a new facility has reached the end of its operating life, before it can be safely transported.
“This raises questions about how could it be stored safely over such a long period.”………http://www.eadt.co.uk/news/mp_warning_over_new_nuclear_power_station_in_essex_1_4246963
New round of debate over Salem nuke’s water intake http://enviropoliticsblog.blogspot.com.au/2015/09/new-round-of-debate-over-salem-nukes.html#.Vf9Nq9KqpHw A regional environmental group set the stage Friday for a new round in the decades long battle over Salem nuclear plant cooling-water demands, submitting the most-detailed critique yet of the site’s 3-billion-gallon-per-day draw from the Delaware River. Jeff Montgomery reports for the The News Journal:
Delaware Riverkeeper, a multi-state environmental and conservation group, said New Jersey’s renewal of a federally required permit for the twin reactors’ intakes would be “irresponsible,” based on newly submitted and past economic and ecological studies.
(1) When nuclear fuel is used in a nuclear reactor or an atomic bomb, the atoms in the fuel are “split” (or “fissioned”) to produce energy. The fission process is triggered by subatomic particles called neutrons. In a nuclear reactor, when the neutrons are stopped, the fission process also stops. This is called “shutting down the reactor.”
(2) But during the nuclear fission process, hundreds of new varieties of radioactive atoms are created that did not exist before. These unwanted radioactive byproducts accumulate in the irradiated nuclear fuel — and they are, collectively, millions of times more radioactive than the original nuclear fuel.
(3) These newly created radioactive materials are classified as fission products, activation products, and transuranic elements. Fission products — like iodine-131, cesium-137 and strontium-90 — are the broken pieces of atoms that have been split. Activation products— like hydrogen-3 (“tritium”), carbon-14 and cobalt-60 — are the result of non-radioactive atoms being transformed into radioactive atoms after absorbing one or more stray neutrons. Transuranic elements — like plutonium, neptunium, curium and americium — are created by transmutation after a massive uranium atom absorbs one or more neutrons to become an even more massive atom (hence “transuranic,” meaning “beyond uranium”).
(4) Because of these intensely radioactive byproducts, irradiated nuclear fuel continues to generate heat for years after the fission process has stopped. This heat (“decay heat”) is caused by the ongoing atomic disintegration of the nuclear waste materials. No one knows how to slow down or shut off the radioactive disintegration of these atoms, so the decay heat is literally unstoppable. But decay heat does gradually diminish over time, becoming much less intense after about 10 years.
(5) However, in the early years following a reactor shutdown, unless decay heat is continually removed as quickly as it is being produced, the temperature of the irradiated fuel can rise to dangerous levels — and radioactive gases, vapors and particles will be given off into the atmosphere at an unacceptable rate.
(6) The most common way to remove decay heat from irradiated fuel is to continually pour water on it. Tepco is doing this at the rate of about 400 tons a day. That water becomes contaminated with fission products, activation products and transuranic elements. Since these waste materials are radiotoxic and harmful to all living things, the water cannot be released to the environment as long as it is contaminated.
(7) Besides the 400 tons of water used daily by Tepco to cool the melted cores of the three crippled reactors, another 400 tons of ground water is pouring into the damaged reactor buildings every day. This water is also becoming radioactively contaminated, so it too must be stored pending decontamination.
(8) Tepco is using an “Advanced Liquid Processing System” (ALPS) that is able to remove 62 different varieties of radioactive materials from the contaminated water — but the process is slow, removal is seldom 100 percent effective, and some varieties of radioactive materials are not removed at all.
(9) Tritium, for example, cannot be removed. Tritium is radioactive hydrogen, and when tritium atoms combine with oxygen atoms we get radioactive water molecules. No filtration system can remove the tritium from the water, because you can’t filter water from water. Released into the environment, tritium enters freely into all living things.
(10) Nuclear power is the ultimate example of the throwaway society. The irradiated fuel has to be sequestered from the environment of living things forever. The high-quality materials used to construct the core area of a nuclear reactor can never be recycled or reused but must be perpetually stored as radioactive waste. Malfunctioning reactors cannot be completely shut off because the decay heat continues long after shutdown. And efforts to cool a badly crippled reactor that has melted down result in enormous volumes of radioactively contaminated water that must be stored or dumped into the environment. No wonder some have called nuclear power “the unforgiving technology.”…….http://akiomatsumura.com/2013/06/experts-explain-effects-of-radioactive-water-at-fukushima.html
Claims that uranium mining near the Grand Canyon is safe don’t hold water, Guardian, David Kreamer, 25 Aug 15 Science shows we can’t assume that uranium deposits, when disturbed by mining, can’t leak into groundwater. We should be wary of claims to the contrary It only takes a few Grand Canyon hikes to realize the importance of its springs and other water sources. When refilling a water bottle in the cool depths below multi-colored rock walls, listening to a summer frog symphony at sunset or maybe snapping an icicle from a weeping ledge in winter, it’s clear that the living desert depends on its pockets of water.
That’s why, as a hydrologist and longtime Grand Canyon hiker, boatman and scientist, I am profoundly concerned about continued uranium mining in or near it. It has great potential to irreparably harm Grand Canyon springs and the plants and animals that depend on them.
I am concerned because industry and agency officials are relying on a justification that isn’t supported by past investigations, research or data to promote uranium mining in the Grand Canyon region. Specifically, they claim that mining will have minimal impact on springs, people and ecosystems there.
Instead, the science shows that it is unreasonable to assume that uranium deposits, when disturbed by mining, can’t leak into groundwater. The deposits in the Grand Canyon are typically found in geologic features known as breccia pipes, formed millennia ago when caves in the main groundwater system collapsed, leaving shattered, rock-filled chimneys that extend upwards thousands of feet to the canyon’s rim. These chimneys act as conduits that have allowed groundwater to move vertically through the rock layers over thousands of years. The vertical movement of groundwater combined with low oxygen levels caused the uranium deposits to form over millennia. Inserting a mine shaft into these features disrupts geologic formations, increases the permeability and oxygenation of these vertical pipes and increases the ability of ore deposits to be suddenly dissolved, mobilized and carried with groundwater.
It is unreasonable to assume that elevated concentrations of dissolved uranium cannot be mobilized and will not reach the Grand Canyon’s springs. It is also risky for industry to assume that mining activities, such as the sinking of mining shafts and pumping of groundwater, have no potential to redirect groundwater movement and negatively impact spring flow and associated wildlife habitats……..
Some mining representatives have implied that the cosmetic fix of cleaning up the surface of old mining sites is evidence of zero subsurface pollution. But because groundwater flow can be very slow, the effects of groundwater contamination may take years, decades or even centuries to fully manifest. The lack of clear and consistent groundwater monitoring undercuts industry claims that mining near the Grand Canyon has caused and will cause no harm……….http://www.theguardian.com/commentisfree/2015/aug/25/uranium-mining-grand-canyon-groundwater-contamination
Record summer heat is bringing fire danger to nuclear stations in the Northern Hemisphere. That’s bad enough, and already is placing pressure on precious water supplies, as near Chernobyl, and in California, fire-fighting goes on.
Shortage of water means that uranium and nuclear facilities are taking much needed water away from agriculture and town supplies. In South Australia, BHP’s massive Olympic Dam uranium mine is the biggest water guzzler in the State.
Extremely hot weather means that rivers and marine areas risk heat pollution from nuclear cooling water. When this happens, nuclear reactors must close down.
China, for example, with its plan for inland nuclear reactors, is faced with this problem.
But China also shares with other nuclear countries,the climate change problem of its many reactors located on the coast. That’s the threatening problem of rising sea levels, storm surges, typhoons, even tsunamis.
EPA raises permissible levels of radiation in drinking water https://thewrongblogg.wordpress.com/2015/08/04/epa-raises-permissible-levels-of-radiation-in-drinking-water/ The White House has given final approval for dramatically raising permissible radioactive levels in drinking water and soil following “radiological incidents,” such as nuclear power-plant accidents and dirty bombs. The final version, slated for Federal Register publication as soon as today, is a win for the nuclear industry which seeks what its proponents call a “new normal” for radiation exposure among the U.S population, according Public Employees for Environmental Responsibility (PEER).
Issued by the Environmental Protection Agency, the radiation guides (called Protective Action Guides or PAGs) allow cleanup many times more lax than anything EPA has ever before accepted. These guides govern evacuations, shelter-in-place orders, food restrictions and other actions following a wide range of “radiological emergencies.” The Obama administration blocked a version of these PAGs from going into effect during its first days in office. The version given approval late last Friday is substantially similar to those proposed under Bush but duck some of the most controversial aspects: Continue reading
US Nuclear plants doing Problem Evaluation Reports on ‘complex and urgent’ situation of water seepage

TVA’s Boone Dam repair announcement, Jul 30, 2015 (emphasis added):
- 2:30 — The location of this sinkhole and the presence of the sediment… really raised the possibility of a safety concern with the dam… The initial investigation showed that we had internal erosion. A phenomenon called ‘piping’ where voids from water flowing through the dam — more of a stream-like effect — than just seepage. Internal erosion is one of the leading causes of dam failures around the world. So we knew that we had to do something here to protect the safety of the public… particularly downstream risk… Around the clock inspectors [are] keeping surveillance on the dam [and we have] sensors to monitor movements that might occur in the dam itself.
- 4:00 — One of the key findings so far is that water is flowing through the foundation from multiple sources, and in multiple directions. It’s actually seeping through porous rock — rainwater upstream, through porous rock, through the dam…
- 9:15 — There’s still a lot of unknowns as we move into the project.
- 21:30 — There’s only 3 companies in the world that do this kind of remediation.That’s the complexity we’re talking about.
- 24:00 — Reporter: You said that water was coming from multiple sources and moving in multiple directions. To the people who are watching… I would think they would think that seems like an impossible task to do. There are some… in this community who think… that Boone Dam can’t be fixed… Is there a possibility that these solutions that you’re proposing won’t work?
TVA’s Boone Dam Investigation and Analysis Summary: [There is] “internal erosion,” in which voids develop within a dam and/or its foundation because of the action of flowing groundwater… one of the leading causes of dam failures… March of 2015, TVA discovered a well-developed, complex network of groundwater seepage paths coming from sources other than the reservoir… surface runoff flows underneath the dam and is a leading contributor to the observed seepage and sinkhole… Further investigation has confirmed that deterioration of the cutoff trench has occurred as seepage flows continue to undermine the foundation of the embankment dam… If left unaddressed, continued internalerosion may lead to enlargement of the network of voids at which time a large influx of water into the voids could cause rapid acceleration of internal erosion and eventual breaching of the dam. Due to the complex and urgent nature of the situation at Boone Dam, TVA has complemented its own dam safety engineers with nationally recognized experts… In its current state, the dam cannot be relied upon to serve the functions for which it was constructed. In the unlikely event of a dam failure, risks to the public wouldinclude: … loss of critical infrastructure [and] potential loss of life… [We are] engaging local and state emergency management officials… developing specific plans to address potential emergencies and conducting mock exercises to execute those plans. TVA has also initiated efforts to reinforce downstream facilities in a way that will minimize potential risks from an unlikely failure of Boone Dam.
TVA’s Boone Dam Weekly Update, Jun 23, 2015: Our investigation has shown that more water is seeping through the foundation of the dam than would typically be expected. A contributor to the seepage is the high water table from the area just east of the dam. Both sources of seepage and subsequent erosion have created an extensive network of seepage paths beneath the dam… TVA Dam Safety experts [are] working to understand the extent of the seepage and erosion…

Radiation found in Greene County stream near water supply Biologist concerned about residents’ health By Paul Van Osdol, Pittsburgh’s Action News Jul 16, 2015 FREDERICKTOWN, Pa. —Action News Investigates has learned high levels of radiation — up to 60 times higher than the maximum allowed in drinking water — have been found in a stream that feeds into a water treatment plant. VIDEO: Watch Paul Van Osdol’s report
The high levels of radiation were found in a Greene County stream that flows into the Monongahela River. Ultimately, that water ends up in Pittsburgh.
Ken Dufalla of the Izaak Walton League conservation group has been taking samples from 10 Mile Creek for years, frequently finding high levels of total dissolved solids.
“I wouldn’t touch it. As you can see, I try to keep my hands off it all I can because I don’t know what’s in this water,” Dufalla said.
To find out exactly what is in the water, he pressed the state Department of Environmental Protection to do comprehensive testing.
The results showed levels of radium 226 and radium 228 totaling 327 picocuries per liter at one location, and 301 picocuries per liter of radium 226 at another location.
In plain English, that means both samples had 60 times the EPA drinking water standard of 5 picocuries per liter.
“There’s something in here that’s not supposed to be here,” Dufalla said.
Ten Mile Creek feeds into the Mon River near Fredericktown. Less than a mile down river is a water treatment plant, and that is a major concern for regulators and area residents.
John Stolz, a biologist at Duquesne University, says radium can be hazardous.
“The reality is, if it’s getting into the water that is being used as a source of drinking water, then it is a problem,” Stolz said.
One big problem is water authorities cannot easily get rid of radium through the standard filtering process.
Tests by the Tri-County Joint Municipal Authority last year found low levels of radium 228 — just 1 picocurie per liter. But the authority did not test for radium 226, and it did not do any radium testing in 2012 or 2013.
It’s not just drinking water that’s a concern. The Izaak Walton League canceled plans to stock 10 Mile Creek with trout this year after consulting with state officials.
“Do you want to eat fish that has radiation in it? It’s that simple,” Dufalla said………
The DEP is concerned enough that it is also doing additional testing of water, fish and wildlife in the area.
“We’re trying to attack this from every possible angle to see what the extent of the contamination is, if there is extensive contamination, what it’s affecting, and tracking it down,” Poister said.
The DEP is especially interested in finding the source of the radiation. Stolz says the test results offer a clue.
“It’s highly suggestive that it may be due to drilling operations, or at least the wastewater,” Stolz said……… http://www.wtae.com/news/radiation-found-in-greene-county-stream-near-water-supply/34205428
