Lithium is an important component in the supply chain of vital technological industries. Therefore, it critical to accurately analyze lithium's ability fulfill demand for lithium consumption. The concentration rivers, lakes, and seawater on Bangka Island was examined using ICP-OES. XRD SEM-EDX were used confirm carrier minerals rock morphology around waters. showed highest level, averaging 0.28 ppm. Other essential elements, including boron cobalt, had average levels 2.90 ppm 0.93 ppm, respectively. results can be improve effectiveness initial exploration surveys.

This article introduces the GALDITE methodology, an adaptation of GALDIT used to assess seawater intrusion in coastal aquifers. incorporates a new parameter (E) focusing on groundwater exploitation through artesian wells, previously overlooked GALDIT. The methodology evaluates vulnerability using parameters like aquifer type, hydraulic conductivity, distance coastline, and now extraction impact. Statistical validation Barreiras data confirms effectiveness enhancing model accuracy. Sensitivity analysis highlights parameter's significant influence overall assessment. results indicate that key impact zones identified include downstream regions São Mateus, Doce, Itabapoana rivers, as well municipality Vitória, highlighting applicability GALDITE. utility managing water resources, governance, guiding sustainable strategies is emphasized, particularly face increasing risks exacerbated by intensive extraction. study underscores necessity integrating into assessments for effective management.

This paper presents the construction of a numerical three-dimensional model area Żelazny Most Mining Waste Storage Facility (MWSF). In study area, difficult geological conditions associated with glaciotectonics are accompanied by complex hydrotechnical system sediment deposition and sedimentary water drainage. order to effectively reflect flow paths, detailed schematization was carried out, using 700,000 boreholes more than 300 hydrogeological cross-sections. addition, numerous drainage sections, streams, ditches were included reliably assess amount saline entering underlying aquifers. research supported magnetic resonance sounding (MRS) studies reservoir’s sediments. The MWSF is currently being expanded, so work primarily focuses on illustrating changes in hydrodynamic field resulting from inclusion new southern section. Models similar facilities have been implemented before, but current one, combination meticulous analysis hydro-structural system, balance, significant data, size facility, use an unstructured discretization grid calculations undoubtedly innovative will be important contribution development analogous solutions around world.

Tailings dams' disasters begin a stage of river water contamination with no endpoint at first sight. But when the was formerly used for public supply and use suspended as consequence dam break, time window safe suspension lift must be anticipated to help managers. The purpose this study seek that moment in case Brumadinho disaster which occurred 2019 injected millions cubic meters iron- manganese-rich tailings into Paraopeba River, leading Belo Horizonte metropolitan region resource, until now. To accomplish proposed goal, an assemblage artificial intelligence socio-economic development models were anticipate precipitation, discharge metal concentrations (iron, manganese) 2033. Then, ratios between impacted non-impacted sites determined values representing extreme events selected further assessment. A ratio ≈1 generally indicates similarity areas or, put another way, return pre-rupture condition. Moreover, is estimated under influence peak flows, then value conditions most unfavorable hydrologic regimes, thus return. So, plotted against fitted straight line intercept-x requested time. results pointed 6.57 years after accident, while using iron contaminant indicator, or 8.71 manganese considered. Despite being relatively low-risk timeframe, should implemented phases monitored precaution potential sporadic events, dredging from continue accelerated.
