Canada will add PFAS, which are linked to cancer and other health problems, to toxic substances list | CBC News

The federal government is moving to add PFAS, a class of thousands of chemicals used in a wide range of products from food containers to clothing, to the official list of toxic substances, in light of growing scientific and public concern about the substances in Canada and around the world. PFAS, or per- and polyfluoroalkyl substances, are man-made chemicals used for their water and heat resistant properties. They are widely used in many everyday products — such as packaging, cosmetics and textiles — along with industrial uses like water-repellent coatings and firefighting foam.

As part of this effort, the Molecular Design and Synthesis Group at the University of New South Wales has been designing tagging agents that will temporarily introduce highly fluorinated alkyl groups to molecules to aid in organic synthesis (for example, see figure 18.17).

EPA says 'forever chemicals' more dangerous than previously believed

16June2022

The Environmental Protection Agency on Wednesday said that so-called forever chemicals pose a greater health threat than previously believed. These man-made compounds, known as polyfluoroalkyl and perfluoroalkyl substances, or PFAS, are found in drinking water, cosmetics, and food packaging, exposing millions of Americans. The EPA's new advisory says lifetime exposure to the most common of these substances, PFOA and PFOS, even at the low levels of 0.004 and 0.02 parts per trillion, respectively, can harm immune and cardiovascular systems. They have also been linked to low birth weights. The guidance is intended to push local officials to install water filters and warn consumers of the threat of contamination. [The Washington Post]

US Military Bases Are Poisoning Okinawa

The U.S. military has contaminated the drinking water for almost half-a-million Japanese – but Japanese authorities can’t do anything about it.

By Jon Mitchell

Host to 31 U.S. military bases, Okinawa, Japan’s southernmost prefecture, is no stranger to the risks of bearing the burden of the U.S.-Japan alliance. In 1959, the U.S. military accidentally shot a nuclear rocket into a local harbor; six years later, it lost a hydrogen bomb in nearby seas; then in 1969, a leak of nerve agent on the island so shocked the world that President Richard Nixon was forced to renounce his nation’s first-use policy on chemical weapons.

But these incidents pale compared to what Okinawans are facing today: the U.S. military has polluted the drinking water for 450,000 people – a third of the prefecture’s population – in the worst case of environmental contamination in the island’s history.

The chemicals causing the problem are per- and polyfluoroalkyl substances (aka PFAS) which are used in the production of food wrapping, nonstick cookware and military firefighting foams. PFAS are highly resistant to heat, oil and water, but in these strengths lie their dangers. Virtually indestructible in nature, they accumulate in our bodies, taking decades to expel. According to the U.S. Agency for Toxic Substances and Disease Registry, health problems linked to PFAS include cancers of the kidneys and testicles, high cholesterol and decreased vaccine response – a particular concern during the current pandemic.

Okinawans first realized their island was contaminated with PFAS in 2016 when tests by local authorities detected high levels of the substances in rivers running through and near Kadena Air Base, the largest U.S. Air Force installation in the Pacific. The discovery prompted further checks near military facilities on the island, revealing elevated PFAS levels in spring water, fish and farmers’ fields. Most alarming, prefectural officials found PFAS in the island’s drinking water, which is sourced from rivers near Kadena Air Base and an aquifer beneath the facility. Levels peaked at 120 parts per trillion (ppt); as a comparison, the U.S. Environmental Protection Agency recommends a maximum level of 70 ppt – but even this, say experts, is way too high.

White House Moves to Weaken EPA Rule on Toxic Compounds

The Trump White House intervened to weaken one of the few public health protections pursued by its own administration, a rule to limit the use of a toxic industrial compound in consumer products, according to communications between the White House and Environmental Protection Agency.

Small signal boost doubt many people care cause most don’t but we buy this shit. So need to remind people to look out cause god knows the President and the others don’t give a shit.

Analysis | The Energy 202: Pentagon watchdog agency to examine military’s use of toxic 'forever chemicals'

PFAS are the subject of a new movie and lawmakers' ire.

Excerpt from this Washington Post Energy 202 story:

The Pentagon’s inspector general is examining the military’s use of a dangerous but ubiquitous class of man-made chemicals that has leached into the drinking water of millions of Americans, including many living near military bases across the country.

The compounds — known as polyfluoroalkyl and perfluoroalkyl substances, or PFASs — have for years been used in specialized firefighting foams on military bases.

Now the military’s watchdog agency will assess the legacy of using those chemicals. Among the questions the inspector general's office may address are what the Pentagon knew about the dangers posed by the chemicals, how well the military has communicated those risks to service members and how quickly it plans to phase out their use.

The Pentagon assessment will bring the issue of PFAS contamination even more to the fore than it already is, with dozens of members of Congress on both sides of the aisle clamoring for regulators to do more and with a major Hollywood film about the toxic chemicals slated for release next month.

Its widespread use at U.S. bases around the world — most notably during firefighting training exercises — had led to the buildup of the chemical in groundwater near military installations. The Defense Department is tracking at least 401 sites for potential PFAS contamination.

That contamination is dangerous because exposure has been associated with an array of health problems, including thyroid disease, weakened immunity, infertility and certain cancers. And once in the water, the chemical can last for a long time without being naturally broken down — leading many to call them “forever chemicals.”

Water Contamination Continues on Military Bases

Water Contamination Continues on Military Bases

In 2018, we wrote about the water contamination at 126 military bases. The DoD is working to clean it up, and has begun mitigation on those sites with the installation of filtration systems.  The total number of military sites known to have contamination has risen to 297, according to the Environmental Working Group.

“Out of the 90 additional sites, the worst contamination was detected at the…

The Trump administration has placed a former Koch Industries official in charge of research that will shape how the government regulates a class of toxic chemicals contaminating millions of Americans’ drinking water

— Citizens for Ethics‏ @CREWcrew - Feb 5, 2019

From POLITICO

What’s the best way to prevent companies from the pesky profit sucking costs of following regulations and lawsuits? Stop it from the inside —  at the source.

Safe drinking water ¯\_(ツ)_/¯ Cancer  ¯\_(ツ)_/¯ Drink up America!

The Trump administration has placed a former Koch Industries official in charge of research that will shape how the government regulates a class of toxic chemicals contaminating millions of Americans’ drinking water — an issue that could have major financial repercussions for his former employer.

David Dunlap, a deputy in EPA’s Office of Research and Development, is playing a key role as the agency decides how to protect people from the pollution left behind at hundreds of military bases and factories across the country.

Previously undisclosed documents obtained by POLITICO show Dunlap began working on the issue almost immediately upon arriving at EPA in October. He had spent the previous eight years as Koch Industries' lead expert on water and chemical regulations, a position that typically includes helping companies to limit regulatory restrictions and liability for cleanups.

“Known as per- and polyfluoroalkyl substances, or PFAS, the chemicals have been linked with kidney and testicular cancer, as well as other ailments.”

Both Republicans and Democrats have urged a stronger approach from acting EPA Administrator Andrew Wheeler
