Article history:


Received 24 March 2014 Study region: The area of study is the northern part of Belgium (Flanders).


Received in revised form 4 August 2014 The seven evaluated Aquifer Thermal Energy Storage (ATES) systems are pos-

itioned in key aquifers, which contain major groundwater resources for the

Accepted 9 August 2014
region.

Available online 15 September 2014

Study focus: The increasing number of ATES systems leads to concerns by

drinking panies and environmental regulators about the long term
Keywords:

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 parison of groundwater quality monitoring data at seven ATES sys-

Review tems with ambient groundwater quality values from 69 monitoring wells.

Temperature New hydrological insights for the region: The results of the analysis of the

Mixing hydrochemical data confirm that the small temperature differences (T ≤ 10)


Potable water supply at which the ATES systems are operating do not influence t
