The SALT Project, represented by Rendell Molina of the University of the Philippines Los Baños (UPLB), presented the team's study "Assessment of the Tidal Influence on the Coastal Aquifer of Sanga-Sanga Island, Tawi-Tawi, Philippines" at the 9th International Conference on Sustainable Development of Water and Environment, held in Phuket, Thailand from 25 to 27 July 2026.

The study is one of the outputs of SALT Project, a collaborative project with UPLB (implementing agency) and DLSU, with the support of the Bongao Municipal Government. The project aims to assess the extent of seawater intrusion in Sanga-Sanga Island, Tawi-Tawi, and understand its implications for local water sources in the municipality of Bongao. As many Philippine island communities rely on groundwater for their daily water needs, understanding how tides influence coastal aquifers is essential for protecting freshwater resources and supporting long-term water security.
