TL;DR: In this article, a numerical model was used to evaluate how the concentration of ethanol in reformulated gasoline affects the length and longevity of benzene plumes in fuel-contaminated groundwater.

TL;DR: Benzene plume elongation and longevity were more pronounced in the presence of alcohols that biodegrade slower (e.g., propanol and n-butanol), forming longer and more persistent alcohol plumes, illustrating the significant effect that a small difference in chemical structure can have on biodegradation.

TL;DR: In this article, the authors demonstrated the direct synthesis of an electrolyte-free aqueous solution of pure H2O2 by developing a photoelectrochemical (PEC) system with solid polymer electrolyte (SPE) and engineered electrodes.

TL;DR: Toluene dioxygenase in Pseudomonas putida F1 was used as a model to determine if enzymes that initiate aerobic BTEX degradation can be expressed at very low dissolved oxygen (DO) concentrations, and it was suggested that aerobic biotransformations are likely to contribute to BTX bioremediation even when an aerotolerant anaerobic respiration mode is prevalent.

TL;DR: In this paper, ethanol was released into the upper capillary zone in a continuous flow, sand-packed aquifer tank (8.2 m 3 ) with an average seepage velocity of 0.75 m/day.
