Seawater intrusion, south coast of Puerto Rico, 1966-77

January 1, 1979

A salinity reconnaissance of the south coast alluvial aquifer of Puerto Rico, including the areas of Guenica, Guayanilla-Yauco, Tallaboa, Juana Diaz, and Jobos was made during 1966-68. In this investigation seawater was detected in the Guayanilla-Yauco and Tallaboa areas.

Since 1968, water level and quality-of-water data have been collected from selected wells in the south coastal areas between Guanica and Patillas. The 1968-77 study indicated two additional areas of possible seawater intrusion in the Ponce-Santa Isabel area. Another area of possible seawater intrusion was found in the southeastern section of the Salinas fan in the Jobos area.
