U.S. Drinking Water Contamination Far Worse Than Previously Thought

Dark humor comedian George Carlin liked to say that he didn’t consider himself a good American if he didn’t let his food and water poison himself a bit every day. For real though, if you want at least some defense against the contamination, the people in the know recommend robust water filtration systems.

America is great again! Keep this version of America great 2020, don’t change it! Only over a hundred million people there drink contaminated water every day!

The contamination of US drinking water with manmade “forever chemicals” is far worse than previously estimated with some of the highest levels found in Miami, Philadelphia and New Orleans, said a report on Wednesday by an environmental watchdog group.

The chemicals, resistant to breaking down in the environment, are known as perfluoroalkyl substances, or PFAS. Some have been linked to cancers, liver damage, low birth weight and other health problems.

The findings here by the Environmental Working Group (EWG) show the group’s previous estimate in 2018, based on unpublished US Environmental Protection Agency (EPA) data, that 110 million Americans may be contaminated with PFAS, could be far too low.

“It’s nearly impossible to avoid contaminated drinking water from these chemicals,” said David Andrews, a senior scientist at EWG and co-author of the report.

The chemicals were used in products like Teflon and Scotchguard and in firefighting foam. Some are used in a variety of other products and industrial processes, and their replacements also pose risks.

Of tap water samples taken by EWG from 44 sites in 31 states and Washington DC, only one location, Meridian, Mississippi, which relies on 700ft (215m) deep wells, had no detectable PFAS. Only Seattle and Tuscaloosa, Alabama had levels below 1 part per trillion (PPT), the limit EWG recommends.

In addition, EWG found that on average six to seven PFAS compounds were found at the tested sites, and the effects on health of the mixtures are little understood. “Everyone’s really exposed to a toxic soup of these PFAS chemicals,” Andrews said.

In 34 places where EWG’s tests found PFAS, contamination had not been publicly reported by the EPA or state environmental agencies.

The EPA has known since at least 2001 about the problem of PFAS in drinking water but has so far failed to set an enforceable, nationwide legal limit. The EPA said early last year it would begin the process to set limits on two of the chemicals, PFOA and PFOS.

The EPA said it has helped states and communities address PFAS and that it is working to put limits on the two main chemicals but did not give a timeline.

In 2018 a draft report from an office of the US Department of Health and Human Services said the risk level for exposure to the chemicals should be up to 10 times lower than the 70 PPT threshold the EPA recommends. The White House and the EPA had tried to stop the report from being published.

How Toxic Chemicals Are Robbing Vulnerable Children of Millions of IQ Points

The crisis of contaminated water seen in Flint, Michigan is ongoing and terrible, but other related events of contamination are more common than people tend to think they are. America is a society with many protections for the most powerful, and not enough for the most vulnerable.

The chemicals we’ve long feared the most – heavy metals like lead and mercury – are less of a threat to kids’ developing brains than they were two decades ago. But two new menaces may be taking their place: pesticides and flame retardants.

According to new research from New York University, flame retardants resulted in a loss of 162 million IQ points among children in the US between 2001 and 2016.

The study, published Tuesday in the journal Molecular and Cellular Endocrinology, looked at the four chemicals known to impact the brain of a developing child most: lead, mercury, pesticides, and polybrominated diphenyl ethers (otherwise known as flame retardants).

Leo Trasande, a paediatrician and public-health researcher at NYU who co-authored the study, described these pollutants as “hit-and-run” chemicals: Once a child is exposed to them, there’s no reversing the damage.

“Kids’ brain development is exquisitely vulnerable,” Trasande told Business Insider. “If you disrupt, even with subtle effects, the way a child’s brain is wired, you can have permanent and lifelong consequences.”

The study found that lead cost US kids 78 million IQ points during the 15-year period studied, while pesticides caused a loss of nearly 27 million IQ points during those years. Mercury, meanwhile, caused a loss of 2.5 million IQ points.

Children’s’ lower IQs are costing the US trillions of dollars

The researchers found that among kids exposed to toxins from 2001 to to 2016, the proportion of IQ loss due to exposure to flame retardants and pesticides increased from 67 percent to 81 percent. Flame retardants can be found in household furniture and electronics, while pesticides can be consumed when they linger on produce.

“What we found was quite striking,” Trasande said.

“We know that there is no safe level of lead exposure. The same is true for methylmercury, pesticides, and flame retardants.”

The study also found that there is an economic cost to childhood brain damage: Trasande said that each individual IQ point is worth roughly 2 percent of a child’s lifetime economic productivity. So if a child could potentially make US$1 million over the course of their lifetime, they would lose US$20,000 for every IQ point lost.

“A kid’s brain power is the engine of our economy,” Trasande said.

“If a child comes back from school with one less IQ point, maybe mum or the parent might not notice. But if 100,000 children come back with one less IQ point, the entire economy notices.”

According to the researchers, IQ loss due to lead, mercury, flame retardants, and pesticide exposure combined cost the US around US$6 trillion from 2001 to 2016.

Regulations on flame retardants and pesticides are more lax than heavy metals

For decades, scientists have understood that exposure to lead and mercury can result in childhood brain damage. So many of the main hideouts for these chemicals – leaded gasoline, lead paint, and mercury emissions from coal-fired power plants – have been phased out.

As early as the 1970s, the Environmental Protection Agency required lead to be phased out of gasoline and paint (though lead paint can still be found in homes built before 1978).

The agency also set standards to reduce mercury emissions from coal-fired power plants in 2011, though some power plants still do not meet these requirements.

But there have been fewer efforts to regulate pesticides and flame retardants.

The EPA has banned around 37 pesticides, though more than 500 have been used in the US. Another 97 have been voluntarily withdrawn by pesticide manufacturers.

More than a dozen states have adopted legislation that restricts the use of flame retardants in products like furniture, carpeting, and children’s toys, but none of the chemicals are banned federally.

Ways to reduce kids’ exposure

Many factors can influence a kid’s exposure to a chemical, Transande said.

“The science has really evolved such that the dose is not the only thing that makes the poison,” he said. Other factors to consider could include the timing and frequency of exposure.

Trasande added that regulating all of these chemicals has a far lower long-term economic cost than the cost of kids’ lost IQ points due to exposure.

To minimise personal risk in one’s own home, Trasande suggested simple steps like opening windows so that dust laced with flame retardants can escape. He also suggested vacuuming frequently and using a wet mop to sop up chemicals on the floor.

In addition, parents should avoid mattresses and children’s toys that contain polyurethane foam (which often carries flame retardants).

Trasande also said households should avoid spraying pesticides on their lawns or backyards and recommended switching to organic foods (though organic produce can also contain pesticides).

“We’ve made less progress in phasing out or banning some of the pesticides of greatest concern,” Trasande said. “But there are steps we can take proactively as consumers.”

EPA Blocked Release of Major Water Contamination Report

All of the wealth in world history’s wealthiest country and it still isn’t using those resources to provide access to safe drinking water for tens of millions. America is a plutocracy though, and while it remains that way, the society’s structure will primarily prioritize making the rich richer over much else.

The chemicals that were under review are PFOA and PFOS, which, as Politiconotes, “have long been used in products like Teflon and firefighting foam”—as well as by the Department of Defense, when it conducts exercises at U.S. bases—despite the fact that they “have been linked with thyroid defects, problems in pregnancy, and certain cancers, even at low levels of exposure.”

The study, conducted by the Department of Health and Human Services’ (HHS) Agency for Toxic Substances and Disease Registry (ATSDR), reportedly shows that these chemicals are dangerous to human health at far lower levels than previously known or disclosed by the EPA, and have “contaminated water supplies near military bases, chemical plants, and other sites from New York to Michigan to West Virginia.”

Creating Medicines With Less Side Effects Through a New Chemical Dividing Process

Overall, medications today have way too many harmful side effects, and so this breakthrough technological process should be helpful in reducing them. It also has the potential to “produce better medical and agricultural products, including medicines, food ingredients, dietary supplements and pesticides.”

Chemical compounds are made up of molecules. The most important molecules in biology are chiral molecules. “Chiral,” the Greek word for “hand,” describes molecules that look almost exactly alike and contain the same number of atoms but are mirror images of one another — meaning some are “left-handed” and others are “right-handed.” This different “handedness” is crucial and yields different biological effects.

Understanding chiral differences was made painfully clear by the drug thalidomide. Marketed to pregnant women in the 1950’s and 1960’s to ease morning sickness, thalidomide worked well under a microscope. However, thalidomide is a chiral drug -its “right” chiral molecule provides nausea relief while the “left” molecule causes horrible deformities in babies. Since the drug company producing Thalidomide did not separate out the right and left molecules, Thalidomide had disastrous results for the children of women who took this medication.

Though a crucial step for drug safety, the separation of chiral molecules into their right- and left- handed components is an expensive process and demands a tailor-made approach for each type of molecule. Now, however, following a decade of collaborative research, Paltiel and Naaman have discovered a uniform, generic method that will enable pharmaceutical and chemical manufactures to easily and cheaply separate right from left chiral molecules.

Their method relies on magnets. Chiral molecules interact with a magnetic substrate and line up according to the direction of their handedness — “left” molecules interact better with one pole of the magnet, and “right” molecules with the other one. This technology will allow chemical manufacturers to keep the “good” molecules and to discard the “bad” ones that cause harmful or unwanted side effects.

“Our finding has great practical importance,” shared Prof. Naaman. “It will usher in an era of better, safer drugs, and more environmentally-friendly pesticides.”

While popular drugs, such as Ritalin and Cipramil, are sold in their chirally-pure (i.e., separated) forms, many generic medications are not. Currently only 13% of chiral drugs are separated even though the FDA recommends that all chiral drugs be separated. Further, in the field of agrochemicals, chirally-pure pesticides and fertilizers require smaller doses and cause less environmental contamination than their unseparated counterparts.

Study: Personal Care Products Inhaled en Masse Contribute to Harmful Pollution “Rush Hour”

As if the air in much of the world wasn’t already polluted enough, this study reconfirms the importance of changing transportation systems to be far less dependent on fossil fuels and also the apparent importance of designing better personal care products.

When people are out and about, they leave plumes of chemicals behind them — from both car tailpipes and the products they put on their skin and hair. In fact, emissions of siloxane, a common ingredient in shampoos, lotions, and deodorants, are comparable in magnitude to the emissions of major components of vehicle exhaust, such as benzene, from rush-hour traffic in Boulder, Colorado, according to a new CIRES and NOAA study.

This work, published in the journal Environmental Science and Technology, is in line with other recent findings that chemical emissions from personal care products can contribute significantly to urban air pollution.

“We detected a pattern of emissions that coincides with human activity: people apply these products in the morning, leave their homes, and drive to work or school. So emissions spike during commuting hours,” said lead author Matthew Coggon, a CIRES scientist at the University of Colorado Boulder working in the NOAA Earth System Research Laboratory.

D5 Siloxane, short for decamethylcyclopentasiloxane, is added to personal care products like shampoos and lotions to give them a smooth, silky feeling. Siloxane belongs to a class of chemicals called volatile organic compounds (VOCs); once applied, they evaporate quickly. In the air, sunlight can trigger those VOCs to react with nitrogen oxides and other compounds to form ozone and particulate matter — two types of pollution that are regulated because of their effects on air quality and human health.

This study is part of an emerging body of research that finds emissions from consumer and industrial products are important sources of urban air pollution. A recent study in Science, led by CIRES and NOAA’s Brian McDonald, found that consumer and industrial products, including personal care products, household cleaners, paints, and pesticides, produced around half of the VOC emissions measured in Los Angeles during the study period.

DuPont Concealed Dangerous Health Risks Caused by Teflon Globally

This DuPont case is a significant example of corporate crime and the damage it causes. The toxic chemicals in Teflon provide ample reasoning to simply use different products (such as cast iron pans) and avoid exposure to the potentially harmful chemicals in Teflon.

Broadcasting from the Sundance Film Festival, we are joined by three guests who personally battled with DuPont and are featured in the new documentary called “The Devil We Know,” that looks at how former DuPont employees, residents and lawyers took on the chemical giant to expose the danger of the chemical C8, found in Teflon and countless household products—from stain- and water-resistant apparel to microwave popcorn bags to dental floss. The chemical has now been linked to six diseases, including testicular and kidney cancers.

AMY GOODMAN: We are broadcasting from the Sundance Film Festival in Park City, Utah. Nearly 70 years ago, the chemical giant DuPont introduced a product that would transform how people around the world cook: nonstick Teflon pans.

[…]

AMY GOODMAN: The chemicals in the product, C8, went on to be used in countless household products, from stain- and water-resistant apparel to microwave popcorn bags to dental floss. But DuPont had a secret it never told the American public or many of its own workers: C8 is highly toxic. But that didn’t stop them from discharging C8 into the waterways around its manufacturing plant in Parkersburg, West Virginia. It’s now been linked to six diseases, including testicular and kidney cancers. The chemical has been used so widely, it’s now in the bloodstream of 99 percent of Americans, even newborn babies. And the chemical is bioresistant, meaning it does not break down.

The struggle to discover the truth about C8 and hold DuPont accountable is the subject of a stunning new documentary that premiered here at Sundance. It’s called The Devil We Know.

New Process Could Increase the Value of Captured Carbon Dioxide

In my view, carbon capture will probably be necessary to mitigate the worst effects of climate change in the future. The beneficial incentives for capturing it are therefore welcome developments. Also, this possible development is not the only recent advance in carbon capture — there is also a more definitive recent advance that converts captured carbon dioxide into valuable chemicals.

Carbon capture could help the nation’s coal plants reduce greenhouse gas emissions, yet economic challenges are part of the reason the technology isn’t widely used today. That could change if power plants could turn captured carbon into a useable product.

Scientists at the U.S. Department of Energy’s Idaho National Laboratory have developed an efficient process for turning captured carbon dioxide into syngas, a mixture of H2 and CO that can be used to make fuels and chemicals. The team has published its results in Green Chemistry, a publication of the Royal Society of Chemistry.

Traditional approaches for reusing the carbon from CO2 involve a reduction step that requires high temperatures and pressures. At lower temperatures, the CO2 doesn’t stay dissolved in water long enough to be useful. The process developed at INL addresses this challenge by using specialized liquid materials that make the CO2 more soluble and allow the carbon capture medium to be directly introduced into a cell for electrochemical conversion to syngas.

“For the first time it was demonstrated that syngas can be directly produced from captured CO2 — eliminating the requirement of downstream separations,” the researchers wrote in the Green Chemistry paper.
