John Holden travels across Indonesia, Canada and three states to understand sequestration from oil drilling waste, "copper and health" and more.

In the field of disease ecology, the outcomes of disease outbreaks in wildlife communities with varying biodiversity is the subject of intense debate.

These enhanced attenuation remedies replace less sustainable remedial methods like dig & haul or pump & treat, which create more PFAS waste materials.

Chlorinated solvent usage at a former printing facility in Orange County, California (Figure 1) contaminated the soil, soil vapor, and groundwater with tetrachloroethene (PCE) and trichloroethene (TCE).

GA-EMS’ iSCWO system processes organic waste with water in an extremely high temperature (650F) and high pressure (4000 psi) environment to efficiently destroy both PFAS and other hazardous and non-hazardous waste.

Cost estimates are based on the required upgrades to Minnesota’s existing wastewater infrastructure to treat and destroy PFAS using current commercially available technologies and PFAS levels.

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.
