I recently posted a question about why my article on contamination simulation was not being accepted by reputable journals, even though I need it to be published in a Q1 journal. Thank you to everyone who responded, and special thanks to the friend who suggested sharing my abstract for more tailored guidance. I’m posting the abstract below, and I would be grateful for any comments or recommendations that could help improve it for submission to a high-impact journal. Thank you in advance for your time and support."Abstract
The oil pollution caused by leakage from fuel storage tanks at railway stations produces various environmental problems and, in the case of the Tabriz railway station, has intensified social conflicts. This study investigates this issue through backward modelling approach using MT3DMS coupled to MODFLOW to simulate and predict the transport and fate of polycyclic aromatic hydrocarbons (PAHs) under multiple scenarios: continuous leakage, cessation of leakage, and natural attenuation. The results show that continuous leakage maintains persistently high PAH concentrations, whereas a 50% reduction in source concentration reduces the contaminant plume by more than 48%. Relying on natural attenuation alone would require more than 50 years to eliminate the contamination. Since this passive process cannot restore the aquifer within an acceptable timeframe, the SEAM3D model was used to evaluate active bioremediation options.
The model predicts that, if all leakage ceases by 2024, implementing bioremediation could achieve complete aquifer remediation in approximately 20 months. To validate these findings, a pilot-scale remediation was conducted in selected wells, incorporating influencing factors through a multi-criteria decision method using machine learning algorithms, including ANN, KAA, XGBoost, and Random Forest. XGBoost was selected to stratify and prioritize wells for real site remediation effort, based on performance metrics. Results indicated that the air sparging bioremediation achieved a treatment efficacy of 75% over four months, while the pump-and-treat approach reached an efficiency of 24.26%. It is suggested to continue bioremediation efforts in other wells to achieve complete remediation that meets the standards defined by the US EPA."
