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.

Accurate sampling of PFAS is vital because the data received provides insights into their potential health risks and what strategies should be used for remediation or water treatment. 

Their models are applicable for fresh and saltwater and account for the type, size, shape and ionic charge of the microplastics; as well as the functional compound groups and chain length of PFAS.

Here's a May 23 remediation news roundup surrounding Superfund and brownfield sites from the U.S. EPA.

At the outset, PFAS@Mines will focus on four interdisciplinary efforts aimed at the development of more cost-effective and sustainable technologies for remediating PFAS-contaminated water and soil.

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.

Handling or using fluorinated containers is a significant pathway for unsafe human exposure to PFOA and other PFAS. 

The lawsuit alleged that the commonwealth failed to prevent the toxic chemicals from contaminating the environment.

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."

With labeling of toxic chemicals, workers and communities throughout the plastic waste stream can be alerted when they need to take precautions.
