| Popis: | The concept of the aquifer is introduced and the characteristics of subsurface rocks to form a groundwater-bearing formation are analysed in this work. The conceptual model of groundwater flow in the granitic aquifer of the Maresme and its connection with the aquifers on the coastal plains are studied, as well as the connection with the alluvial aquifers of the lower part of the La Tordera river and delta. How the water recharge takes place and how natural and artificial discharges occur are also studied. The impacts on the system caused by artificial discharges are also analysed. The analysis includes the quantitative and qualitative state of groundwater based on the water bodies defined by the Catalan Water Agency. The problem of groundwater contamination by chlorinated solvents in the aquifer of the stream of Sant Pol de Mar is presented as an example of the pressures related to groundwater quality. Finally, the origin of the Maresme geothermal manifestations (geothermal waters and springs of sparkling water), which is related to groundwater flow through deep faults and extends beyond the surficial granitic aquifer system is also studied. |
