“…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.

“…The temperature influences the aquifer ecosystem by altering the solubility of minerals (Arning et al 2006) as well as by changing the availability of organic matter (OM) and macronutrients (Klein 1989, Brons et al 1991, Bonte et al 2011a, b, 2013a, b, Jesußek et al 2013a and thus, influencing the biological activity. OM serves as a carbon and/or energy source for microbial metabolism.…”

“…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).…”

“…This process creates a cycle of seasonal thermal energy storage. (Arning et al, 2006;Bonte et al, 2011a;Brielmann et al, 2011Brielmann et al, , 2009Brons et al, 1991;Griffioen and Appelo, 1993;Hall et al, 2008;Zhu et al, 2011). In addition, according to EU environmental policy, these impacts should be minimized so that no detrimental effects can occur (EU-WFD, 2000).…”

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.
