Groundwater lowering in karstic aquifers due to agricultural activity in the Fucino plain (Abruzzi, Central Italy)
Ezio Burri, Marco Petitta - (27/1,1998)
The alluvial-lacustrine sediments that fill the Fucino Plain (>200 km2) contain an important aquifer, mostly fed by the karstic water. The Plain displays high vulnerability by agricultural activity (potential pollution, depletion of groundwater resources). In order to find water, more than 200 wells have been drilled since the 1950s, with a seasonal delivery of about 2,000,000 m3. The possible consequences can be summarised: 1. Decreased efficiency of the operating wells because of the lowering of the piezometric levels. This kind of problem is already evident and it may determine economic losses and environmental degradation, especially if the summer water shortage causes precarious hygienic conditions in the canal network of the Plain. 2. Reduced discharge in springs. This phenomenon involves the decrease of both available drinking water supplies and regular downflow in the canals. 3. Increased vulnerability of the surrounding carbonate aquifers by the infiltration of poor-quality irrigation waters in the karst aquifers.
