Society relies on large amounts of energy to progress and allow for a high standard of living. The recent severe climate changes require advanced technologies related to cleaner energy resources. One such technology beneficial for accelerating this current energy transition is geothermal energy. This type of energy is often found in fractured...

Utilizing coral aggregate concrete (CAC) for construction on remote islands can significantly reduce construction cost and period, CO<sub>2</sub> emission, and consumption of non-renewable energy. The durability of reinforced CAC structures is critically influenced by their resistance to chloride attack. In this study, a reactive transport...

Push-pull tests (PPTs) were evaluated with 1-D radially axisymmetric multi-component geochemical reactive transport modelling (RTM) to assess aquifer reactivity controlling groundwater quality. Nutrient fate and redox processes were investigated in an Aquifer Storage and Recovery (ASR) system, in which oxic tile drainage water (TDW; nitrate ...

Stability of dikes is a national security issue for densely populated low-lying countries situated in delta areas, like the Netherlands. One of the dominant dike failuremechanisms in the Netherlands is piping, where high seepage flow rates transport sand particles and subsequently form a ’pipe’ under a dike structure. As such, one manner to...

Microbially mediated sulfate reduction is a ubiquitous process in many subsurface systems. Isotopic fractionation is characteristic of this anaerobic process, since sulfate-reducing bacteria (SRB) favor the reduction of the lighter sulfate isotopologue (S<sup>32</sup>O<sub>4</sub><sup>2−</sup>) over the heavier isotopologue (S<sup>34</sup>O...

Using naturally occurring processes to modify the engineering properties of the subsurface has received increasing attention from industry and research communities as they aid in the development of cost-effective, robust and sustainable engineering technologies. In line with this trend, we propose to use precipitates of aluminum (Al) and organic...

Reaction rates for different minerals are usually measured in ideal conditions in batch experiments, where the impact of pore morphology and hydrodynamics have been fully neglected. Such reaction rates are used at continuum-scale (Darcy-scale) models without the impact of pore structure on upscaled reaction rates under flow conditions. Therefore...

This paper presents an investigation of coupled thermal, hydraulic, and chemical behavior of a compacted bentonite buffer under the heating and hydration conditions of geological disposal of high-level nuclear waste. The study presented provides further insight into the evolution of hydro-geochemistry of the compacted bentonite and the clay...

In-depth water diversion is a chemical Enhanced Oil Recovery (EOR) method that has been gaining acceptance recently for several reasons. One of them is the fact that sodium silicate, used in this method, is one of the few green chemicals used in EOR. In addition, this chemical has shown the ability to generate thermally activated plugs far away...

Coastal aquifer management has recently emerged as a main scope in groundwater hydrology, especially in arid and semi-arid zones. About two thirds of the human population are currently gathered close to shorelines relying on coastal groundwater resources. Worldwide, these systems are subject to quality deterioration due to a multitude of...

The principle of Subsurface Arsenic (As) Removal (SAR) is to extract anoxic groundwater, aerate it and reinject it. Oxygen in the injected water reacts with iron in the resident groundwater to form hydrous ferric oxide (HFO). Dissolved As sorbs onto the HFO, which allows for the extraction of groundwater with lower As concentrations.

Reactive transport modeling of multi-element, compound-specific isotope analysis (CSIA) data has great potential to quantify sequential microbial reductive dechlorination (SRD) and alternative pathways such as oxidation, in support of remediation of chlorinated solvents in groundwater. As a key step towards this goal, a model was developed...

Enhanced in situ biodenitrification (EIB) is a feasible technology to clean nitrate-polluted groundwater and reach<br/>drinking water standards. Aimed at enabling a better monitoring and management of the technology at the field<br/>scale, we developed a two-dimensional reactive transport model (RTM) of a cross section (26.5 × 4 m) of a...

In order to simulate microbially influenced mineral precipitation process, a 1D reactive transport model is developed. The developed reactive-transport model consists three components: MATLAB (main stream), ORCHESTRA (equilibrium reaction processor) and EXCEL (user interface). The established model as a generic tool enables the simulation of one...

Predicting the evolution of groundwater contamination is a major concern for society, in particular when investments are made to remediate the contamination. Groundwater reactive transport models are valuable tools to integrate the available measurements in a consistent framework, improving our understanding of the physical system and...

Parameter estimation of subsurface transport models from multispecies data requires the definition of an objective function that includes different types of measurements. Common approaches are weighted least squares (WLS), where weights are specified a priori for each measurement, and weighted least squares with weight estimation (WLS(we)) where...

Coupled reactive-transport processes in cementitious materials play a crucial role in the aging process pf building materials. Up to now, the effect of aging on microstructure and evolution of it’s properties, in three dimensions, was studied only by dissolution of certain phases at random locations. In this paper we present a new 3D reactive...

A Lattice Boltzmann (LB) based reactive transport model intended to capture reactions and solid phase changes occurring at the pore scale is presented. The proposed approach uses LB method to compute multi component mass transport. The LB multi-component transport model is then coupled with the well-established geochemical reaction code PHREEQC...

An oil-soluble chemical (OSC) is a chemical substance which is soluble and chemically inert in oil, but reacts with water to form a gel. Application of an OSC can be found in oil- and gas production. An increased water production, which usually occurs in mature oil fields, can be remedied by injecting the OSC in the near-wellbore area. The OSC...
