The problem is further complicated by persistent drought of recent years, which has resulted in prolonged periods of reduced streamflow. This issue has prompted research on possibility of finding practical techniques for flow stoppage of saline springs by investigating their recharge and salinization mechanisms as well as emergence time. To this end, the Shirinrud river in southern Iran is selected as a case study. While this river contains freshwater flow, it is intensively salinized due to annual discharge of ∼110000 tons salt from the Romqan saline spring. Study area streamflow gauges, water sampling, plus field observations and measurements have been used to provide the required data and information. Data analyses included evaluation of temperature variations of study area groundwaters, long-term salinity of the Shirinrud River, and isotopic and hydrochemical compositions of water samples. Results of thermal, isotopic, and hydrochemical tracing methods together with hydrogeological evidences in the Romqan spring site indicated that although the Romqan saline spring is recharging from a fresh groundwater flow, it becomes intensely salinized due to passage of ∼1.7 km of its recharging water pass inside the Romqan salt diapir. Furthermore, sudden drying of a freshwater spring at border of Romqan salt diapir just after the 1999 earthquake in spring site area, resulted in redirection of the fresh groundwater flow of the dried spring into the Romqan salt diapir, followed by emergence of the Romqan saline spring in the Shirinrud River bed. For flow stoppage of the Romqan saline spring, an interceptor drainage system is suggested, which would divert the spring fresh recharging groundwater flow at border of Romqan salt diapir and finally desalinize the Shirinrud River from Romqan saline spring.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"27 ","pages":"Article 101370"},"PeriodicalIF":4.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such regions have not been identified systematically in the Indo-Gangetic basin, one of the most fertile alluvial aquifers in the world. This identification may be enabled by a study of how seasonal changes in subsurface characteristics affect groundwater levels. We conducted a resistivity survey in Nanoor block of the Lower Ganges Basin, where groundwater levels have declined steeply in recent decades, to determine how subsurface characteristics controlling infiltration and groundwater quality may change seasonally. Vertical Electrical Soundings (VES) using the Schlumberger electrode array were conducted over an 8 km² area with an electrode spacing of 180-200 meters during the pre-monsoon (April 2018) and post-monsoon (October 2018) seasons. Seasonal variations in the Dar- Zarrouk parameters: longitudinal conductance, transverse resistance, and the coefficient of anisotropy were evaluated. While the average longitudinal conductance remained unchanged across seasons, it increased in certain locations in post-monsoon, indicating potential risks of contamination from the surface. The transverse resistance significantly increased in the post-monsoon, suggesting reduced groundwater potential. Additionally, in some areas, the coefficient of anisotropy indicated increased compaction of overburden layers in the post-monsoon, suggesting decreased natural recharge potential. Finally, the thickness of the unsaturated zone increased significantly from pre-monsoon to post-monsoon, which may be attributed to groundwater withdrawal for irrigation during the Kharif cropping season. These results indicate that this region, heavily reliant on groundwater for irrigation, is characterized by subsurface properties that allow limited natural recharge potential. This study may provide a framework for managing groundwater resources in developing countries where anthropogenic withdrawals are likely to have a more significant impact on groundwater levels than reduced natural recharge due to changing rainfall characteristics.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"27 ","pages":"Article 101368"},"PeriodicalIF":4.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional bioremediation techniques, limited to 30–50% efficiency, underscore the need for more effective solutions. This review highlights recent advancements in microbial bioremediation strategies, demonstrating removal efficiencies of 80–90% through the utilization of functional microorganisms, which metabolize PAHs into non-toxic compounds. Innovative techniques such as genetic engineering, microbial immobilization, and nanotechnology are shown to achieve over 90% pollutant removal. The review discusses key metabolic pathways and enzymatic processes driving PAH degradation, such as ring-hydroxylation and oxygenation. Techno-economic assessments indicate up to 40% cost savings and improved energy efficiency compared to conventional methods, facilitating scalability for large-scale environmental restoration projects. Microbial solutions for groundwater pollution, where PAH levels often exceed the maximum contaminant level (MCL) of 0.2 μg/L, are found to be highly effective in mitigating ecological risks and protecting public health.

The waters of the Metauro River area represent a fundamental resource exploited daily for drinking, agricultural, and industrial uses. The anthropic pressure exposes the water resources to depletion and quality degradation risks, making the study area of high scientific and social interest. The hydro-geochemical approach revealed that the interaction between water and local lithologies led to Ca²⁺-HCO₃^- compositions, with less frequent Na⁺(K⁺)-Cl^- and Ca²⁺-Cl^- hydrofacies and variable salinity (up to 55 meq/L). Most waters showed natural (e.g., halite and evaporite contribution) and anthropogenic (sewage, septic tanks, manure, urban wastewater, and industrial effluents contribution) inputs confirmed by both Na⁺, Cl⁻, NO₃⁻, and SO₄²⁻ enrichments and high Cl/Br ratios. The anthropogenic contributions is further confirmed by the relatively high contents of TPTEs (Total Potentially Toxic Elements), even though these elements individually present values below the Italian Normative Legislative limit. Geochemical issues are mitigated during the year when the surface aquifer is recharged by the river, characterized by a better overall chemical quality. The occurrence of this relationship is of interest to the local authorities in charge of the water resource management. In fact, groundwater exploitation could be increased during specific periods, thus decreasing the anthropic pressure on the river waters, usually exploited for drinking purposes even during the summer seasons when the hydrometric levels drastically drop.
