“…For all geochemical reactions, two categories of reactions exist: kinetic and equilibrium. Assuming that there are NE fast/equilibrium reactions (all of which must be independent) and NK slow/kinetic reactions [ 16 ], then the number of reactions will be: N = NE + NK.…”

“…Source characterization is the first step towards reliable and sustainable contamination remediation. The issue of accurately characterizing contaminant sources at poorly monitored abandoned mining sites is crucial since the soil matrix and groundwater contamination have important influences on human health, vegetation and ecological systems [ 16 ]. Thus, solving contaminant source problems in complex aquifers characterized by many aquifer parameter dissimilarities requires methods that are robust, efficient and able to handle data uncertainty [ 17 ].…”

The most important first step in the management and remediation of contaminated groundwater aquifers is unknown contaminant source characterization. Often, the hydrogeological field data available for accurate source characterization are very sparse. In addition, hydrogeological and geochemical parameter estimates and field measurements are uncertain. Particularly in complex contaminated sites such as abandoned mine sites, the geochemical processes are very complex and identifying the sources of contamination in terms of location, magnitude, and duration, and determination of the pathways of pollution become very difficult. The reactive nature of the contaminant species makes the geochemical transport process very difficult to model and predict. Additionally, the source identification inverse problem is often non-unique and ill posed. This study is about developing and demonstrating a source characterization methodology for a complex contaminated aquifer with multiple reactive species. This study presents linked simulation optimization-based methodologies for characterization of unknown groundwater pollution source characteristics, i.e., location, magnitude and duration or timing. Optimization models are solved using an adaptive simulated annealing (ASA) optimization algorithm. The performance of the developed methodology is evaluated for different complex scenarios of groundwater pollution such as distributed mine waste dumps with reactive chemical species. The method is also applied to a real-life contaminated aquifer to demonstrate the potential applicability and optimal characterization results. The illustrative example site is a mine site in Northern Australia that is no longer active.

Effective water resource management offers a very significant value across social, economic, commercial and environmental application. For this fundamental reason, adequate sustainability becomes equally crucial. Therefore, activities geared towards the depletion in quantity, quality, and loss of potable water resources, particularly for communities, demand urgent reconsiderations. Erosion in coal mining land causes depletion in water quantity and quality, as well as inadequate drinking water resources for surrounding communities, making water resources unsustainable. Meanwhile, reclamation reduces erosion, but is unable to restore water depletion optimally, thus, these resources remain unsustainable. these resources remain unsustainable. However, recycling depleted water utilization for drinking provides economic value for the environment, as well as the community’s drinking water resources’ availability and sustainability. The objectives of this study were to develop water resource sustainability concept for a sustainable environment by analyzing the potential economic value and secondly, calculate the water resource value due to erosion, reclamation, domestic and economic importance, by recycling efforts. The method used in this study was the Extended NPV. Furthermore, the total potential economic value of water resources loss resulting in water resource unsustainability was IDR 1,137,621,671,375 or IDR 1.14 trillion, while the potential economic value of depleted water utilization for drinking was IDR 2,298,339,797,000 or IDR 2.3 trillion. Therefore, this utilization provides potential economic value worth IDR 1.16 trillion, for the resources’ sustainability in the TAL area of PTBA. The study’s results found and recommended depleted water utilization for drinking as a suitable method to replace water resources lost due to erosion, community drinking water resource loss, and to discover a sustainable environment’s water resources sustainability concept. In addition, the study formulates environmental economics as a new mining science related to natural resource economics as well as mining, for sustainable water resources and mining environment.

Infrastructure supporting the transition of human societies from fossil fuels to renewable energy will require hundreds of millions of tons of metals. Polymetallic nodules on the abyssal seabed of the Clarion‐Clipperton Zone (CCZ), eastern North Pacific Ocean, could provide them. We focus on ethical considerations and opportunities available to the novel CCZ nodule‐collection industry, integrating robust science with strong pillars of social and environmental responsibility. Ethical considerations include harm to sea life and recovery time, but also the value of human life, indigenous rights, rights of nature, animal rights, intrinsic values, and intangible ecosystem services. A “planetary perspective” considers the biosphere, hydrosphere, and atmosphere, extends beyond mineral extraction to a life‐cycle view of impacts, and includes local, national, and global impacts and stakeholders. Stakeholders include direct nodule‐collection actors, ocean conservationists, companies, communities, interest groups, nations, and citizens globally, plus counterfactual stakeholders involved with or affected by intensification of terrestrial mining if ocean metals are not used. Nodule collection would harm species and portions of ecosystems, but could have lower life‐cycle impacts than terrestrial mining expansion, especially if nodule‐metal producers explicitly design for it and stakeholders hold them accountable. Participants across the value chain can elevate the role of ethics in strategic objective setting, engineering design optimization, commitments to stakeholders, democratization of governance, and fostering of circular economies. The International Seabed Authority is called to establish equitable and transparent distribution of royalties and gains, and continue engaging scientists, economists, and experts from all spheres in optimizing deep‐sea mineral extraction for humans and nature. Nodule collection presents a unique opportunity for an ambitious reset of ecological norms in a nascent industry. Embracing ethical opportunities can set an example for industrial‐scale activities on land and sea, accelerate environmental gains through environmental competition with land ores, and hasten civilization's progress toward a sustainable future.
