SEAWATER INTRUSION IN CARBONATE AQUIFERS: THE CASE OF THE SPRING GROUP OF CASTELLAMMARE DI STABIA (NAPLES, SOUTHERN ITALY)

Understanding salt water intrusion in coastal aquifers is very important for appropriately managing water resources, especially in fractured and karst aquifers. This study analyses the salt water intrusion phenomenon in the carbonate aquifer of the Mount Faito near the spring area of Castellammare di Stabia. In this area, groundwater outfl ow near the coastline reaches a total of about 0.5 m(3)/s, from various springs that differ from one another in discharge rate and water chemistry.
