    PFAS ‘Forever Chemicals’ Are Pervasive in Water Worldwide, Study Finds

    A global survey found harmful levels even in water samples taken far any obvious source of contamination.They’re in makeup, dental floss and menstrual products. They’re in nonstick pans and takeout food wrappers. Same with rain jackets and firefighting equipment, as well as pesticides and artificial turf on sports fields.They’re PFAS: a class of man-made chemicals called per- and polyfluoroalkyl substances. They are also called “forever chemicals” because the bonds in their chemical compounds are so strong they don’t break down for hundreds to thousands of years, if at all.They’re also in our water.A new study of more than 45,000 water samples around the world found that about 31 percent of groundwater samples tested that weren’t near any obvious source of contamination have PFAS levels considered harmful to human health by the Environmental Protection Agency. About 16 percent of surface water samples tested, which were also not near any known source, have similarly hazardous PFAS levels.This finding “sets off alarm bells,” said Denis O’Carroll, a professor of civil and environmental engineering at the University of New South Wales and one of the authors of the study, which was published on Monday in Nature Geoscience. “Not just for PFAS, but also for all the other chemicals that we put out into the environment. We don’t necessarily know their long-term impacts to us or the ecosystem.”High levels of exposure to some PFAS chemicals have been linked to higher cholesterol, liver and immune system damage, hypertension and pre-eclampsia during pregnancy, as well as kidney and testicular cancer.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    New E.P.A. Rules Aim to Minimize Damage From Chemical Facilities

    The rules require facilities to explicitly address threats such as wildfires or flooding, including those linked to climate change.The Biden administration issued new rules on Friday designed to prevent disasters at almost 12,000 chemical plants and other industrial sites nationwide that handle hazardous materials.The regulations for the first time tell facilities to explicitly address disasters, such as storms or floods, that could trigger an accidental release, including threats linked to climate change. For the first time, chemical sites that have had prior accidents will need to undergo an independent audit. And the rules require chemical plants to share more information with neighbors and emergency responders.“We’re putting in place important safeguards to protect some of our most vulnerable populations,” Janet McCabe, Deputy Administrator of the Environmental Protection Agency, told reporters ahead of the announcement.Administration officials called the stronger measures a step forward for safety at a time when hazards like floods and wildfires — made more extreme by global warming — pose a threat to industrial sites across the country. In 2017, severe flooding from Hurricane Harvey knocked out power at a peroxide plant outside Houston, causing chemicals to overheat and explode, triggering local evacuations.Some safety advocates said the rules don’t go far enough. They have long called for rules that would make facilities switch to safer technologies and chemicals to prevent disasters in the first place. The new regulations stop shy of such requirements for most facilities.The lack of tougher requirements was particularly disappointing, the advocates said, because President Biden championed similar measures, as senator, to bolster national security.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
