“…Interactions among water-rock-sediment-soil and the mineral composition of the aquifer materials through which water moves play an important role in groundwater chemistry variation and groundwater quality variation. Furthermore, groundwater quality is often degraded by anthropogenic activities (Arumugam and Elangovan 2009;Espinosa et al 2009;Fehdi et al 2009;Kelepertsis et al 2006;Lambrakis 2006;Stamatis and Gartzos 1999;Skeppstrom and Olofsson 2007;Simsek 2008;Liou et al 2009). …”

Groundwater samples were collected from 25 sampling sites of the Oropos-Kalamos basin aiming to describe the groundwater quality in relation to geology, lithology and anthropogenic activities of the study area. Chromium speciation analysis, factor analysis, GIS database and geochemical data proved successful tools for the identification of natural and anthropogenic factors controlling the geochemical data variability and for the identification of the redox couple controlling Cr speciation. A Durov diagram is used to classify groundwater quality into five types: Ca-HCO 3 , Mg-HCO 3 , Na-Cl, Mg-Cl and Ca-Cl. The groundwater quality of Oropos-Kalamos is influenced by various natural and anthropogenic factors. Evaluation of water quality for drinking and irrigation purposes is discussed.

“…This observation is counterintuitive because groundwater generally flows in a radial direction . Although annual evapotranspiration is larger than annual precipitation on Kinmen Island, the existence of meteoric water in the deep rock body explains that there must be a vertical flow path through which water infiltrates faster than it can be evaporated at the surface (Liou et al 2008). …”

Kinmen Island is a small, tectonically stable, granitic island that has been suffering from a scarcity of fresh water resources due to excessive annual evapotranspiration over annual precipitation. Recent studies further indicate that shallow (0-70 m) sedimentary aquifers, the major sources of groundwater supply, have already been over-exploited. Therefore, this preliminary study is to investigate the existence of exploitable water resources that can balance the shortage of fresh water on this island. Site characterization data are obtained from island-wide geophysical surveys as well as small-scale tests performed in a study area formed by three deep (maximum depth to 560 m) vertical boreholes installed in mid-east Kinmen northeast to Taiwu Mountain. Vertical fracture frequency data indicate that the rock body is fractured with a spatially correlated pattern, from which three major fracture zones (depths 0-70, 330-360, and below 450 m) can be identified. Geologic investigations indicate that the deepest fracture zone is caused by the large-scale, steeply dipping Taiwushan fault. This fault may have caused a laterally extensive low-resistivity zone, a potential fractured aquifer, near Taiwu Mountain. The middle fracture zone is induced by the Taiwushan fault and intersects the fault approximately 21 m southeast of the study area below a depth of 350 m. Slug testing results yield fracture transmissivity varying from 4.8 9 10 -7 to 2.2 9 10 -4 m 2 /s. Cross-hole tests have confirmed that hydraulic connectivity of the deeper rock body is controlled by the Taiwushan fault and the middle fracture zone. This connectivity may extend vertically to the sedimentary aquifers through high-angle joint sets. Despite the presence of a flow barrier formed by doleritic dike at about 300 m depth, the existence of fresh as well as meteoric water in the deeper rock body manifests that certain flow paths must exist through which the deeper fractured aquifers can be connected to the upper rock body. Therefore, groundwater stored within the Taiwushan fault and the associated low-resistivity zone can be considered as additional fresh water resources for future exploitation.
