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.
There are more than 12,000 types of PFAS, not all of which can be detected with current tests; the U.S. Geological Survey study tested for the presence of 32 types.
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.
Microbiology professor Mary Beth Leigh and the team found that planting grasses or adding fertilizer, or a combination of both, to a contaminated site had surprisingly persistent effects on the microbes associated with local vegetation.
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.
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.
