Water Quality

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.

A new solid, colloidal organic material (AquiFix) markedly improves remedial outcomes for in situ (i.e., in place) bio-barrier treatments designed to stop migrating CVOC plumes.

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.

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."

A research team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has managed to purify water containing uranium using a special kind of bacteria known as magnetotactic bacteria.

"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."

The microbes produce substances that help to transform the uranium, so that it is more easily incorporated into minerals.

Here's the latest remediation news surrounding Superfund and brownfield sites from the U.S. EPA.

Framework will put people to work in locally led landscape restoration projects driven by collaborative partnerships while advancing climate resilience.

A crew of 270 people are hard at work remediating around nine waste rock piles — which the EPA estimates will cost over $1 billion to clean up.
