Chromium-6 Found in US Cities

The Environmental Working Group released a study last month that showed nearly 90% of American cities have unhealthy levels of cancer-causing chemicals in their tap water. Norman, Oklahoma topped the list, just above Honolulu.

Laboratory tests commissioned by Environmental Working Group (EWG) have detected hexavalent chromium, the carcinogenic “Erin Brockovich chemical,” in tap water from 31 of 35 American cities. The highest levels were in Norman, Okla.; Honolulu, Hawaii; and Riverside, Calif. In all, water samples from 25 cities contained the toxic metal at concentrations above the safe maximum recently proposed by California regulators.

The National Toxicology Program has concluded that hexavalent chromium (also called chromium-6) in drinking water shows “clear evidence of carcinogenic activity” in laboratory animals, increasing the risk of gastrointestinal tumors. In September 2010, a draft toxicological review by the U.S. Environmental Protection Agency (EPA) similarly found that hexavalent chromium in tap water is “likely to be carcinogenic to humans.”

Norman, Oklahoma has just studied and given a public response to the EWG findings.

Water samples recently collected by the city of Norman found levels of chromium-6 ranging from 10 to 90 parts per billion, Utilities Director Ken Komiske said Thursday.

Komiske said the findings were no surprise given Norman’s location and well-documented history of having heavy metals in its drinking water.

Currently, the limit set by the EPA for total chromium in drinking water is 100 parts per billion.

“It is naturally occurring here … it’s going to be in the soil, it’s going to be in your plants and it’s going to be in your water,” Komiske said. “But is it safe to drink? Absolutely.”

An interesting clue to this story is that Komiske is reported to have tested for chromium-6, but he is quoting an EPA limit for total chromium. The two are not the same and the story does not make it clear.

A similar report comes from Syracuse, New York:

[Onondaga County Health Commissioner Dr. Cynthia] Morrow says comprehensive testing programs are in place, and those tests show the amount of chromium is well below state standards. “We have a huge margin of safety before we have any level of concern and that’s for total chromium,” she said.

Total chromium again.

The question raised by the EWG is not for total chromium. It is specific to chromium-6. The EPA has no maximum contaminant level set for chromium-6.

The story from Hawaii shows a far more detailed and informed report than the above two cities.

The Board of Water Supply found the highest level of chromium-6 in Waipahu and the lowest in Wahiawa.

“You don’t want any chromium-6 in the water because there’s always a risk of cancer, but it’s understanding that at very low levels the risk of getting any kind of illness is very low,” said interim Health Director Neal Palafox. “The water by present science is very safe.”

California has a goal of 0.06 ppb for chromium-6 in drinking water.

The chromium-6 is most likely derived from naturally occurring volcanic soils, according to Gary Gill, DOH deputy director for environmental health. “Levels are far below any EPA action levels at this point,” Gill said. “The goal for any contaminant should almost always be zero — that’s a goal, that’s not a health standard.”

Total chromium levels among the Oahu sites tested ranged from 0 to 4.8 ppb.

“To have citizens and people concerned about anything that’s unsafe in the water is always good and should raise red flags,” Palafox said. “The other part of the responsibility is to help people interpret what it means.”

Again we see an official point to EPA levels, yet they fail to mention there is no EPA level for chromium-6. That is the issue. At least the reporter makes it clear. The EPA defends themselves by claiming they simply have not been able to update their rules with current science since 1992:

The current standard is set at 100 parts per billion. EPA’s regulation assumes that the sample is 100% chromium-6. This means the current chromium standard has been as protective and precautionary as the science of that time allowed. The current standard is based on potential adverse dermatological effects over many years, such as allergic dermatitis.

[…]

…EPA is proposing to classify hexavalent chromium (or chromium-6) as likely to cause cancer in humans when ingested over a lifetime. EPA will make a final determination by the end of 2011.

They are not saying chromium-6 should be allowed at 100 parts per billion, they are just saying they are not disallowing chromium-6 as part of the 100 parts per billion because other forms of chromium are not toxic.

In stark contrast to news in Hawaii is a FOX report from Maryland, where an official says there is no need for any safety concern at all until after disaster:

“There is nothing to fear. I’m a Bethesda resident. I drink it all of the time. You’re talking about one test taken at one tap out of 435,000 customers and the level at the tap. There is no science to say what kind of harm this would do to human beings,” said Jim Neustadt with WSSC.

[…]

Why not just test for it? “Because there is nothing that indicates .19 is anything to be concerned about at this time,” said Neustadt.

Nothing indicates risk?

If I lived in Bethesda I would either move away about now or call for Neustadt to test immediately or resign. Even Norman, Oklahoma ran tests before making a public statement on their levels.

Likewise, Maryland fails the Hawaii safety test and education standard because the only data point from Bethesda’s spokesman is that he drinks the water himself; so in just two sentences he completely contradicts himself “I drink it all of the time. You’re talking about one test taken at one tap out of 435,000 customers and the level at the tap.” Either you accept a study methodology or you do not. Which is it?

He also clearly has not read the EPA report that says chromium-6 is considered carcinogenic, and he has not read independent research, let alone the book from 1933 called 100,000,000 Guinea Pigs: Dangers in Everyday Foods, Drugs, and Cosmetics

…the manufacturer is not required to prove that the substances he adds are safe for human consumption; his customers by dying or by becoming ill in large numbers—and in such a way that the illness can be directly traced to the foodstuff involved and to no other cause—must first prove that it is harmful before any action will be considered under the Food and Drugs Act. If prohibition of the poison will not interfere with the business of any large and influential interest, the Government may then take action.

If the poison is such that it acts slowly and insidiously, perhaps over a long period of years (and several such will be considered in later chapters), then we poor consumers must be test animals all our lives; and when, in the end, the experiment kills us a year or ten years sooner than otherwise we would have died, no conclusions can be drawn and a hundred million others are available for further tests.

American regulation of toxicity changed after 1933 because of awareness generated by this book. When a large number of children were killed by poison additive in cough syrup a huge backlash (arguably instigated by the book) led to changes in the laws — poof of safety was increasingly required, rather than proof of harm.

Neustadt must have missed almost 70 years of memos on American health, ethics and risk management. Perhaps he could explain why scientific studies that describe chromium-6 as “toxic” should mean something different in Maryland.

The hexavalent form is toxic. Adverse effects of the hexavalent form on the skin may include ulcerations, dermatitis, and allergic skin reactions. Inhalation of hexavalent chromium compounds can result in ulceration and perforation of the mucous membranes of the nasal septum, irritation of the pharynx and larynx, asthmatic bronchitis, bronchospasms and edema. Respiratory symptoms may include coughing and wheezing, shortness of breath, and nasal itch.

[…]

…health problems that are caused by chromium(VI) are:

– Skin rashes
– Upset stomachs and ulcers
– Respiratory problems
– Weakened immune systems
– Kidney and liver damage
– Alteration of genetic material
– Lung cancer
– Death

Maryland residents may be pleased to hear that a new bill that claims to be based on science instead of one man’s health has been introduced at the federal level to address the risk of chromium-6, timed with the EPA’s re-classification.

S. 79, The Protecting Pregnant Women and Children From Hexavalent Chromium Act of 2011

S. 79 would amend the Safe Drinking Water Act to protect the health of vulnerable individuals, including pregnant women, infants, and children, by requiring a health advisory and drinking water standard for hexavalent chromium.

Cracking the Scratch Lottery Ticket

Wired gives a plausible argument that people who play the scratch lottery and win may have found a way to improve their chances, but that still might not make it a worthwhile pursuit.

His next thought was utterly predictable: “I remember thinking, I’m gonna be rich! I’m gonna plunder the lottery!” he says. However, these grandiose dreams soon gave way to more practical concerns. “Once I worked out how much money I could make if this was my full-time job, I got a lot less excited,” Srivastava says. “I’d have to travel from store to store and spend 45 seconds cracking each card. I estimated that I could expect to make about $600 a day. That’s not bad. But to be honest, I make more as a consultant, and I find consulting to be a lot more interesting than scratch lottery tickets.”

He was thinking small-time business. Someone who wanted to hire a 1,000 mules could probably make the business model sound more lucrative. On the other hand, his target game could also be the limiting factor. Wired points to a winner who repeatedly cashed in big prizes from only a few tickets.

..then there’s Joan Ginther, who has won more than $1 million from the Texas Lottery on four different occasions. She bought two of the winners from the same store in Bishop, Texas. What’s strangest of all, perhaps, is that three of Ginther’s wins came from scratch tickets with baited hooks and not from Mega Millions or Powerball. Last June, Ginther won $10 million from a $50 ticket, which is the largest scratch prize ever awarded by the Texas Lottery.

Perhaps Ginther is simply the luckiest person on earth. (She has refused almost all requests from journalists for comment.)

The bottom-line to the story seems to be “randomness” is known to be flawed yet the industry is slow to respond and fix problems, even after players openly report they are using a key.

Malawi May Pass a Fart Law

Controversy is bubbling up in Malawi thanks to a politician who has decided to push a questionable interpretation of a clean air rule from 1929.

The old law states: “Any person who voluntarily vitiates the atmosphere in any place so as to make it noxious to the health of persons in general dwelling or carrying on business in the neighbourhood or passing along a public way, shall be guilty of a misdemeanour.”

It is hard to see why Justice and Constitutional Affairs Minister George Chaponda would want to broaden the meaning of these words. “Noxious to the health” is far from being anything farted. His misapplication of the terms is made clear when he explains his motives:

The government has a right to ensure public decency. We are entitled to introduce order in the country.

That right/entitlement to decency does not come from the law he has chosen — one that says it is a misdemeanor to make the air noxious to health.

Enforcement brings some obvious problems as well and further emphasizes the problem. The ability to detect things like ammonia, hydrogen sulfide, methane, sulfur dioxide, carbon monoxide, cyanide was developed after many years of lab tests on people who were killed by them. A lack of harm from farts makes reliable detection, let alone prevention, impossible.

Ice Virus Hits Hard in Texas

I reported on an Ice Virus outbreak in Russia at the end of 2010 that affected nearly half a million people in Moscow — critical infrastructure failed.

Now Texas is the one failing from the same attack and infestation.

Perry was quoted as blaming the problems on “unprecedented demand on the state’s energy grid” and saying experts were working “to ensure power is restored as quickly as possible.”

Texas unable to provide sufficient power?

But it was Lt. Gov. David Dewhurst who met with the executives of the state’s power grid manager, ERCOT, and the heads of power generating companies. He said Wednesday that the problem was the failure of some newer plants to sufficiently weatherize.

Two coal-burning plants had frozen water pipes and contributed to 50 of the state’s 550 power plants going off-line.

Dewhurst noted that power demands, while high, were about 20 percent less than what the state handles during peak summer months.

Democrats accused Perry of falling down on the job. The governor “was paying so little attention to the ice storm during his five day trip to California that his own press release misstated the reason for the rolling blackouts,” said Matt Angle of the Democratic Lone Star Project.

I am surprised the Governor was so removed from the situation and made misstatements while his state’s residents suffered through rolling blackouts. It seems obvious, even to an outsider, that demand would not be higher than during the hot summers. Likewise, it seems odd that water pipe failures at just two coal power plants, Oak Grove and Sand Hill, would cascade to 50 more plant failures and have such an impact.

Is your infrastructure prepared for the Ice Virus? Severe weather might actually pose a far greater risk than Stuxnet.

Meanwhile in Antarctica, wind farms have been operating for three years already.

Source: Meridian Energy

The wind farm reduces the carbon footprint of the Antarctic operations, as well as the environmental risks associated with transporting diesel fuel. The bases’ annual fuel consumption has been cut by approximately 463,000 litres. Greenhouse gas production from both bases has been reduced by 1,242 tonnes of CO2.


Update February 2021 (TEN YEARS LATER!):

Texas operates on its own by design and during the current winter storm bad things happened yet again.

Texas has its own grid to avoid dealing with — you guessed it — the feds…

The ICF (consulting firm founded 1969 by a Tuskegee Airman) outage report tells us the 2011 winter led the self-isolating Texans to the wrong solutions, poor decisions, and gas production failed to deliver during cold:

ERCOT’s Extreme Peak Load scenario anticipated demand up to 67.2 GW, but the day-ahead load forecast for 8am Monday was 74.5 GW. ERCOT’s Extreme Peak forecast was based on 2011 winter weather, which resulted in emergency operations but not widespread load shedding.

Gas is blamed so directly for failure to operate. They even make a point to emphasize this was not a renewable energy issue:

Thermal outages, rather than renewables, are the main supply gap.

I know it will become fashionable to say nobody modeled the power system dealing with cold weather (winter storm warning) across all 254 Texas counties but that is LITERALLY WHAT THIS 2011 BLOG POST WAS ABOUT — cold weather change is coming to Texas and it better start planning like Moscow for an “Ice Virus” national security disaster.

And Texas politicians shamelessly boasted as late as 2020 that they were the best planners for energy management, trying to shame Americans outside of Texas.

To put it another way, Texas chose to build only a tiny renewable energy sector and when the gas energy fell offline with nearly 50% failure rates… it’s time to accept responsibility.

Blame Texas gas energy management directly for their totally predictable failure while trying to shame others for what they did themselves.

It’s ridiculous for anyone to say renewables should have suddenly kicked in for a state that didn’t setup weatherized renewables to kick in when their gas systems failed.

On that note, it’s interesting to also read huge amounts of Texas oil production was shut down from an inability to get gas power:

Oil refiner Motiva Enterprises said it was shutting its 607,000 barrel-per-day Port Arthur, Texas, refinery, the largest in the United States. Valero Energy Corp and Total SE separately moved to shut their 335,000 and 225,000 bpd plants in Port Arthur, Texas, due to Monday’s severe cold, sources familiar with plant operations said. Exxon Mobil also began shutting its 369,024 bpd Beaumont refinery and 560,500 bpd Baytown refinery and chemical plant in Texas, sources familiar with plant operations said. Its Baton Rouge, Louisiana, plant also suffered operational issues. Citgo Petroleum Corp said some units at its 167,500 bpd Corpus Christi, Texas, oil refinery were shutting due to weather-related power disruptions.

That’s a LOT of oil wells and refinery to be taken offline. In addition, the same article says gas infrastructure isn’t able to scale to meet demand across a very large region:

Kinder Morgan reported gas-pipeline capacity constraints at locations in Arkansas, Illinois, Louisiana, New Mexico and Texas…

For more detail on this, another article is clear about causes of electricity outages, gas failures:

Officials for the Electric Reliability Council of Texas, which manages most of Texas’ grid, said the primary cause of the outages Tuesday appeared to be the state’s natural gas providers. Many are not designed to withstand such low temperatures on equipment or during production. By some estimates, nearly half of the state’s natural gas production has screeched to a halt due to the extremely low temperatures, while freezing components at natural gas-fired power plants have forced some operators to shut down.

And then they get down to the basic facts with a quote from Michael Webber, an energy resources professor at the University of Texas at Austin:

Texas is a gas state. Gas is failing in the most spectacular fashion.

Even more evidence of this gas failure comes from a tweet by Jesse Jenkins, Professor at Princeton and a prominent energy expert:

As of ~10 AM Eastern time [Monday the 15th], the system has ~30 GW of capacity offline, ~26 GW of thermal — mostly natural gas which cant get fuel deliveries which are being priorities for heating loads — and ~4 GW of wind due to icing. That is a HUGE amount of gas capacity offline, about 30% of total ERCOT capacity and ~half of the natural gas fleet… devastating for reliability

Joshua Rhodes, another energy expert looking at the data, says essentially the same in his tweet

Over 30 GW of generation still down in ERCOT! ~27 GW thermal, or about 35% of all thermal capacity.

Yet, even more importantly, Rhodes also tweeted on the 14th (along with pointing out all systems were affected by the storm) that wind-farms in Texas (albeit very small) over-produced energy far above normal output, because of the… wait for it… high-winds.

Windmills in winter easily can heat their blades and avoid outages, as innovators around the world already documented. Something tells me, however, the real selling point of ice-shedding windmills to Texans would be an opportunity to buy more armored Suburbans that guzzle gasoline:

Skelleftea Kraft maintenance workers ride on armored vehicles when visiting wind sites in the winter

Or look at it this way, a simple table shows wind farms doing ok in a winter storm (forecast demand of 1.8, actual 4.5) yet gas coming up massively short at a much higher scale, leaving a huge -21 deficit in how Texas alone manages its energy.

The numbers don’t lie. The difference from 2011 for me is that investigations will have to start now into whether gas production was shutdown intentionally because of cruel Texas market manipulation and gouging… and Texans willfully ignoring crisis, as well as spending millions on lobbying to prevent better options, all after at least a decade of warnings to weatherize. Some tie it back to 1989 when “wind chills reached 14 degrees below zero”.

Speaking of 1989, that was just a couple years after Enron was started, as Mark Sumner tweeted.

On Monday electricity in Texas approached a rate that would make the average home monthly bill around $96,000… If any of this—purposely constrained market, free floating prices subject to wild changes, consumers facing blackouts—rings a little bell at the back of your head, there’s also this: Enron got its start dabbling in these markets from it’s Houston, TX HQ in the 1980s

A Texas political scientist tweeted that not only does Texas isolate itself to have monopoly control (private regulation to prevent public regulation) in a closed market for energy distribution and pricing, it just used that factor in a disaster to turn down its gas to reduce operating costs while charging Texans higher rates.

All of this summed up by a comment on that tweet:

Dude this is looking more like a Texas version of the 2000-01 California electricity crisis. These private energy producers went offline intentionally and are forcing ERCOT to lift the pricing cap to reflect the scarcity they created.
