dc.description.abstractThis study was undertaken to analyze the saltwater intrusion in the selected municipalities of the first district of La Union. It aimed to 1) determine the water salinity level from shallow tube wells. 2) compare the salinity gradient at different coastal distances, and 3) generate a salinity level map of the coastal agricultural areas. The research design employed was descriptive research, utilizing the T-test assuming equal variance to determine the statistical differences at various coastal distances. The highest average salinity value obtained from all the data was 1533.33 ppm located in barangay Rimos No. 2, Luna, La Union, and 1220 ppm located in barangay Salcedo, Luna, La Union, which was characterized as slightly saline water. Conversely, the lowest average salinity value obtained from all the data was 275 ppm, located in Barangay Sta. Cruz, Bacnotan, La Union, which was characterized as fresh water.
