The type of PFAS remediation technology selected is often a reflection of the PFAS contamination levels and the PFAS signature (i.e. the combination of short- and long-chain PFAS substances present) in conjunction with the site-specific water chemistry and cross contaminants present in the liquid stream.
The differences between additives for fracking in different countries are the type of chemicals used (hazardous, non-hazardous), the disclosure of chemicals and the composition of fracturing fluid. In 2010, Halliburton announced the creation of food additive based hydraulic fracturing fluid in response to calls for transparency and demand for a ...
Perfluoroalkyl and polyfluoroalkyl substances, or PFAS chemicals, are defined as a class of fluorinated organic chemicals containing at least one fully fluorinated carbon.
PFAS compounds and their derivatives are widely used in many products from water resistant textiles to fire-fighting foam. [ 4 ] [ 1 ] PFAS are commonly found in every American household in products as diverse as non-stick cookware, stain resistant furniture and carpets, wrinkle free and water repellent clothing, cosmetics, lubricants, paint ...
It is used as a surfactant and protective coating in applications such as aqueous firefighting foams, textile coating, metal plating and in polishing agents. [ 5 ] [ 6 ] PFHxS production is slowly being phased out since 3M stopped producing C 6 fluorotelomers in 2002, but production by other companies may be ongoing. [ 4 ]
Known as PFAS, the group of manmade chemicals are found in drinking water, food packaging and more. Zach Schiller, research director at Policy […] What forever chemicals are, and how Intel’s ...
Chemicals used for fracking may travel through cracks in the rock into an underground drinking water source and contamination could also occur if a well is improperly installed, if chemicals are ...
Perfluorodecanoic acid (PFDA) is a fluorosurfactant and has been used in industry. [2] PFDA is a member of the group of polyfluoroalkyl substances (PFAS), more specific is it also a perfluoroalkyl acid (PFAA). PFAS, like PFDA, are man-made and are not naturally occurring in nature.
