A staggering 71 to 95 million Americans – more than 20% of the population – may be relying on groundwater contaminated with per- and polyfluoroalkyl substances (PFAS) for their drinking water.

The investment will help the company meet surging demand for its Printed Spacer Technology.

Systems meant to remove arsenic from private well water may be malfunctioning, putting people's health at risk, Rutgers researchers have found.

The stakes are high when it comes to road salts: compromised drinking water, shrinking aquatic habitats and long-term pollution from legacy salt stores in soil and groundwater requiring costly remediation.

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."
