摘要

The over exploitation of geothermal water in Duncun, China, has a considerable environmental impact on groundwater in Quaternary aquifers. This paper discusses the hydrogeochemical characteristics of the geothermal water and groundwater. Special emphasis is put on the study of the impact of the exploitation of geothermal water on groundwater in Quaternary aquifers. The chemical analysis indicates an obvious mixing process in Duncun geothermal field, which is the dominant process that degraded the groundwater quality and resulted in the prevailing undersaturation state of groundwater samples with respect to minerals.
