“…For withstanding reservoir pressure and temperature, such as for treating PFAS in groundwater reservoirs, it is necessary to ensure that the CGAs are stable. Zozulya and Pletneva (2015) developed a patent that applied increasing pressure on the CGAs. The CGAs were produced by homogenizing solutions of a polymer and surfactants in an air‐sealed condition.…”

Per-and polyfluoroalkyl substances (PFAS) are a large group of highly fluorinated, aliphatic chemicals detected throughout the environment, including in human serum.Several regulatory milestones have been achieved in the United States for these environmentally toxic chemicals linked to health problems in humans, the latest one being the US Environmental Protection Agency's (EPA's) PFAS Strategic Roadmap necessitating detection and remediation of PFAS. This article, in addition to briefly discussing these regulatory milestones, evaluates the EPA's detection methods for PFAS including EPA Methods 533, 537.1, and 8327 and other methods currently under development such as the total organic fluorine (TOF) and total organic precursor (TOP) methods. The article also mentions the methods used by other federal agencies for PFAS quantitation. The EPA's drinking water treatability database (TDB) is also described along with the advantages and challenges of the effective treatment methods for PFAS. Most of these treatment methods in the EPA's drinking water TDB face the challenge of disposing wastes containing PFAS, an issue not faced by innovative technologies, and some of these innovative technologies are also discussed. This article will help to understand the current status on the detection and remediation technologies for PFAS treatment in soil and water. It is imperative to have these technologies ready to assist with the remediation objectives in the PFAS Strategic Roadmap.

“…The viscous water phase also entraps gas molecules in the core [13]. Different types of viscosifier have been used, such as the partially hydrolyzed polyacrylamide (PHPA) [14], bentonite [27], styrene-ethylene copolymers [28], some polysaccharides like starch and potassium alginate, but guar gum and xanthan gum are the mostly used ones [15,17].…”

Abstract.1 Aphrons were produced using nonionic surfactants by applying a differential pressure. Bubble size distribution was obtained from optical microscopy using FIJI-ImageJ2 program. The aim of this work was to correlate surfactants structures with aphrons properties (density and viscosity), size distribution and the number of bubbles. API fluid loss tests were based on standard proceedings specifications for water-based drilling fluids of Petrobras/Brazil. The structure of the nonionic surfactants showed a great influence on the fluid properties and the performance of the fluid contributing with a filtrate reduction up to 31% with the systems that were presented between 1088 and 1850 bubbles with diameters ranging from 33 to 104µm. These systems were produced by poly(ethylene oxide) with 7 ethylene oxide units, a poly(ethylene oxide)-b-poly(propylene oxide) with 6 ethylene oxide units and 3 propylene oxide units.
