The authors say their paper "highlights the need for a concerted effort to invest in upgrading our drinking water infrastructure."

The team built several prototypes, with one, three, and 10 stages, and tested their performance in water of varying salinity, including natural seawater and water that was seven times saltier.

At least 45% of the nation’s tap water is estimated to have one or more types of the chemicals known as per- and polyfluorinated alkyl substances, or PFAS, according to a new study by the U.S. Geological Survey.

This is the first peer-reviewed study to show sociodemographic disparities in drinking water PFAS exposures and to statistically link sources such as landfills and airports to PFAS concentrations in community water systems.

According to a news release from the West Virginia Department of Health and Human Resources, over two dozen public water systems in West Virginia have detectable levels of so-called "forever chemicals."

"This work may be pertinent to water quality issues both locally and globally," says Benjamin Shindel, a Ph.D. student in Germany. "We want to see this out in the world, where it can make a real impact."

Many Indonesian environmental regulations have been inspired by US EPA regulations, which have served as an academic reference for Indonesian environmental regulations since the early 2000s.

These grants will enable communities to improve local water infrastructure and reduce emerging contaminants in drinking water by implementing solutions such as installing necessary treatment solutions.

Canada is now proposing a limit of 30 ppt for any detectable per- and polyfluoroalkyl substance, or PFAS, in drinking water sources.

The MCLs for PFOA and PFOS apply to all 3,117 community, nontransient noncommunity, bottled, vended, retail, and bulk public water systems.
