Summary: The mechanistic study of soil and groundwater remediation in petroleum contaminated lands requires rapid qualitative and quantitative identification of petroleum substances. In this study, a strategy using dual-excitation Raman spectroscopy and microscopy was developed for on-site detection and in-situ monitoring of petroleum compositions and contents in soil and groundwater. The method provided detection times of 0.5 hours and one minute, and detection limits of 94 ppm and 0.46 ppm for soil and groundwater samples, respectively. Raman microscopy revealed the petroleum changes at the soil-groundwater interface during the remediation processes. This method can shed light on the petroleum degradation mechanism and facilitate the selection of suitable remediation plans.

Summary: The study investigated the feasibility of using HAP/C-S-H for the remediation of heavy metal pollution in soil and groundwater, showing that high pH and low ion strength are beneficial for copper removal. The maximum adsorption capacity of HAP/C-S-H was found to be higher than that of C-S-H, and the dissolution of copper was significantly reduced at near-neutral pH.

Summary: Monitored natural attenuation (MNA) technology was used to quantify the natural attenuation of carbon tetrachloride contamination in an eastern China polluted site. Results showed that the concentration of carbon tetrachloride in the deep quaternary first aquifer was higher than in the shallow aquifer. The fluctuations in stratigraphy and the heterogeneity of fracture network distribution affected the concentration of carbon tetrachloride.

Summary: Soil vapor extraction (SVE) alone has limitations in removing less volatile compounds in diesel fuel mixtures in the unsaturated zone. This study showed that combining SVE with foam flushing using TW80/SPS foam could enhance the dissolution or mobilization of sorbed diesel in soil. The effectiveness of diesel removal by different foams was observed to be TW80 foam > TW80/SPS foam > N2 gas flow alone, indicating that foam flushing may be a more effective alternative approach for reducing diesel contamination in the unsaturated zone.

Summary: Screening and cultivating crop varieties with low Cd accumulation is an effective way to safely utilize slightly contaminated soil. However, the study found that wheat varieties in low-P soil had significantly higher grain Cd concentration than in high-P soil, exceeding safety guidelines. The difference in soil pH, nutrient levels, and Cd speciation between the two soil types influenced the Cd uptake by the plant varieties.

Summary: This study investigated the simultaneous effects of biochar-supported nanoscale zero-valent iron (nZVI-BC) and water management on the decrease of Cd and As bioaccumulation in rice grain. The results showed that nZVI-BC combined with alternate wetting and drying (AWD) management can simultaneously decrease the bioaccumulation of Cd and As in rice grains. The reduction of soil Cd and As availability and the formation of iron plaque dominated the decrease of Cd and As uptake by rice grains.

Summary: Inorganic pollution, specifically sulfate pollution, is a significant issue in groundwater, impacting the environment and human health. This study focused on a sulfate-contaminated site in Dongying City, Shandong Province, China. A hydraulic barrier was constructed to prevent pollution, and a hydraulic capture technique was used to control water pumping and injection. The treatment process included water pumping, water injection, stoppage of injection and pumping, and chemical precipitation. The results showed a significant decrease in sulfate concentrations in 54% of the samples, indicating that integrated groundwater remediation techniques are more effective.

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.
