Hydraulic fracturing frequently occurs on agricultural land. Yet the extent of sorption, transformation, and interactions among numerous organic frac fluid oil gas wastewater constituents upon environmental release is hardly known. Thus, this study aims to advance our current understanding processes that control fate toxicity commonly used hydraulic chemicals. Poly(ethylene glycol) surfactants were completely biodegraded in topsoil within 42–71 days, but their transformation was impeded...

Combining horizontal drilling with high volume hydraulic fracturing has increased extraction of hydrocarbons from low-permeability oil and gas (O&G) formations across the United States; accompanied by wastewater production. Surface water discharges O&G centralized waste treatment (CWT) plants pose risks to aquatic human health. We evaluated impact surface disposal CWT upstream Conemaugh River Lake (dam controlled reservoir) in western Pennsylvania. Regulatory compliance data were collected...

Hydraulic fracturing fluids are injected into unconventional oil and gas systems to stimulate hydrocarbon production, returning the surface in flowback produced waters containing a complex mixture of xenobiotic additives geogenic compounds. Nonionic polyethoxylates commonly added surfactants that act as weatherizers, emulsifiers, wetting agents, corrosion inhibitors hydraulic fluid formulations. Understanding biodegradability these ubiquitous is critical for water pre-treatment prior reuse...

This work presents the development and characterization of a thermodenuder for study interpretation aerosol volatility. Thermodenuder measurements are further combined with continuous-flow streamwise thermal gradient CCN counter to obtain corresponding hygroscopicity. The response function is characterized monodisperse variable volatility then interpreted comprehensive instrument model embedded within an optimization framework retrieve properties constrained uncertainty. Special attention...
