Summary: This study compares the management costs of flowback and produced water (FPW) from conventional and hydraulically fractured wells using a comprehensive database of oil and gas wells in the Montney Formation, Canada. The results show that conventional and HF oil wells have similar oil-water ratios, while conventional gas wells have higher gas-water ratios than HF gas wells. Master curves for revenue and FPW management costs are provided to analyze the profitability of hydrocarbon recovery processes.

Summary: In recent years, environmental concerns have driven energy companies to modify their industrial activities for greater environmental stewardship. This review discusses the challenges of managing and treating flowback and produced waters in the unconventional oil and gas extraction process, focusing on the most difficult constituents to remove and their environmental impact if left untreated. It also explores the opportunities and feasibility of repurposing produced water for alternative applications and extracting valuable metals using commercially available technologies.

Summary: Oil and gas production generate a large amount of brine wastewater containing various contaminants. The improper disposal of this wastewater may contaminate freshwater aquifers and impact drinking water sources. This study found that chlorinated oil and gas wastewater formed high levels of disinfection byproducts, including trihalomethanes exceeding regulatory limits, while chloraminated wastewater had higher formation of iodinated disinfection byproducts and haloacetamides. These findings highlight the potential adverse impact of oil and gas wastewater on downstream drinking water supplies and public health.

Summary: Hydraulic fracturing uses water and proppants to extract oil and gas, but the resulting wastewater, called flowback and produced water (FPW), contains toxic compounds. Previous research has shown the toxicity of FPW to Daphnia magna (D. magna). This study found that D. magna was unable to recover from a 48-hour exposure to FPW, and the toxicity persisted for at least 19 days post-exposure. The study highlights the importance of considering long-term effects of FPW remediation in spill scenarios.

Summary: This study found that establishing the geochemical and isotopic characteristics of produced water compositions solely based on chemical similarity and comparison with meteoric water and formations could be misleading if these characteristics are assumed to apply across the entire basin. Therefore, factors such as well treatments, completion depth, and lateral location must be taken into account when using produced water compositions to understand fluid flow and trace the sources of hydraulic fracturing fluids.

Summary: This study systematically investigates the relationships between hydraulic fracturing treatment parameters and three optimization goals: uniform fracture propagation, stimulated reservoir volume (SRV) or fracture area maximization, and economic benefit maximization. The results indicate that pursuing different goals may have different impacts on achieving the maximum economic benefit, depending on the geological conditions.

Summary: This study conducted a comprehensive review of the impact of CO2 leakage on overlying aquifers, identifying lead, arsenic, and uranium as the main metals of concern, while cadmium and barium are less of a concern. Carbonate aquifers are more vulnerable to lead and arsenic contamination, but not to uranium.

Summary: The presence of hazardous air pollutants in natural gas may pose risks to human health. This study analyzed unburned natural gas samples from residential stoves in California and found significant regional variability in the concentrations of benzene, toluene, ethyl benzene, and total xylenes. The study estimated that leaked natural gas in California contributes to benzene emissions equivalent to nearly 60,000 light-duty gasoline vehicles, and that leakage from stoves and ovens can lead to indoor benzene concentrations exceeding health standards.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: This study focuses on the development of an air-lift bio-electrochemical reactor (ALBER) with a continuous feeding regime to enhance nitrogen removal from synthetic wastewater. The effect of temperature, hydraulic retention time (HRT), N -NH+4 /TN ratio, and current density on the reactor performance was investigated, and the ALBER achieved a maximum TN removal of 73%. The results suggest that the ALBER has potential for treating industrial wastewater at low temperatures.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
