Influence of Aquifer Thermal Energy Storage on groundwater quality: A review illustrated by seven case studies from Belgium

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... Mehr ...
