“…Most of the published research on chemical impacts focuses on changes in mineral solubility, reaction kinetics, and organic matter oxidation (Holm et al 1987, Brons et al 1991, Griffioen and Appelo 1993, Hoyer et al 1994, Arning et al 2006). The results of these studies suggest that these processes will play a significant role at temperatures > 30°C.…”

ABSTRACT. We present an overview of the risks that underground thermal energy storage (UTES) can impose on the groundwater system, drinking water production, and the subsurface environment in general. We describe existing policy and licensing arrangements for UTES in the Netherlands, as well as the capability of the current and future Dutch policy and legal framework to minimize or mitigate risks from UTES on groundwater resources. A survey at the European Union member state level indicates that regulation and research on the potential impacts of UTES on groundwater resources and the subsurface environment often lag behind the technological development of and ever-growing demand for this renewable energy source. The lack of a clear and scientifically underpinned risk management strategy implies that potentially unwanted risks might be taken at vulnerable locations such as near well fields used for drinking water production, whereas at other sites, the application of UTES is avoided without proper reasons. This means that the sustainability of UTES as a form of renewable energy is currently not fully understood, and the technology may be compromising the natural resilience of the subsurface environment. We recognize three main issues that should be addressed to secure sustainable application of UTES: Scientific research is required to further elucidate the impacts of UTES on groundwater; cross-sectoral subsurface planning is required to minimize negative conflicts between UTES and other subsurface interests; and EU-wide guidelines and standards are required for quality assurance and control when installing UTES systems.

“…Temperature changes can cause alteration of groundwater chemistry as temperature plays a very important role in the solubility of minerals, reaction kinetics, oxidation of organic matter, redox processes and sorptiondesorption of anions and cations (Arning et al, 2006;Brons et al, 1991;Griffioen and Appelo, 1993;Holm et al, 1987;Hoyer et al, 1994;Sowers et al, 2006).…”

“…Most research on this topic is focused on operational aspects such as scaling due to mineral precipitation at high temperatures (>60 • C) (Arning et al, 2006;Griffioen and Appelo, 1993;Holm et al, 1987;Palmer and Cherry, 1984). The goal of these studies was to predict and prevent problems of clogging caused by the effect of temperature changes on mineral equilibria.…”

a b s t r a c t Study region: The area of study is the northern part of Belgium (Flanders). The seven evaluated Aquifer Thermal Energy Storage (ATES) systems are positioned in key aquifers, which contain major groundwater resources for the region. Study focus: The increasing number of ATES systems leads to concerns by drinking water companies and environmental regulators about the long term impacts of ATES systems on the groundwater quality. This study assesses the influence of ATES on groundwater chemistry by means of a literature review, and a comparison of groundwater quality monitoring data at seven ATES systems with ambient groundwater quality values from 69 monitoring wells. New hydrological insights for the region: The results of the analysis of the hydrochemical data confirm that the small temperature differences ( T ≤ 10) at which the ATES systems are operating do not influence the concentrations of the main chemical constituents. Mixing of shallow with deeper groundwater during ATES operation, on the other hand, can alter groundwater quality. The results of this study, however, suggest that the groundwater quality changes are rather small, so that there is no immediate risk for the drinking water supply. However, the installation of ATES systems in the vicinity of public drinking water supply well fields should be handled with care, especially in phreatic aquifers.

El estudio de sistemas geotermales. es abordado en la actualidad mediante la utilización de técnicas geotermométricas clásicas de manera interactiva con otras más complejas de modelización termodinámica por ordenador. Esta situación conduce a una ampliación en la incertidumbre de la situación de equilibrio, derivada de las variaciones de los parámetros termodinámicos incluidos en las distintas bases de datos existentes.En este trabajo se analiza la coherencia entre distintos calibrados del geotermómetro sílice-cuarzo en el rango de temperaturas de O a 100°C, y las expresiones K (T) para la reacción de disolución del cuarzo utilizadas en diferentes códigos de modelización. Salvo algunas excepciones, el error existente en los valores log K previstos por estas funciones para cualquier temperatura dentro del rango establecido, es de ± 0,05, lo cual es aceptable en la mayoría de los casos de utilización práctica.Las expresiones K (T) «anómalas» proceden, bien de la adopción de datos de solubilidad de cuarzo procedentes de experiencias con problemas metodológicos, bien de extrapolar las funciones a límites de temperatura para los que no han sido definidas. Palabras clave: geotermometría, modelización geoquímica, equilibrio cuarzo-solución, K (T). ABSTRACTModem geochemical research on geothermal systems is approached through the interactive use of c1assical geothermometrical techniques and more complex computer codeso This supposes an increase in uncertainities related to the handling of different thermodynamic data-bases. This paper studies the coherence between different silica-quartz geothermometrical calibrates (in the O-lOO"C temperature intervaJ) and the K (T) expresions for dissolution reaction of quartz used in several geochemical codeso With few exceptions, the log K values calculated by these functions at different temperatures agree well with differences of ± 0,05.Anomalies in several K (T) functions are originated both on the use of sorne experimental solubility data with methodological problems in their determination and the extrapolation of these functions outside their temperature limits.
