New Arsenic-Free Water Technology Deployed in Kok River Basin

On September 3, 2026, Prachachat Business reported that Thailand’s Ministry of Higher Education, Science, Research and Innovation (MHESI), in collaboration with the National Science and Technology Development Agency (NSTDA) and the Synchrotron Light Research Institute (SLRI), has officially handed over a new water purification prototype to communities along the Kok River.

The project, known as A-QUALITY, focuses on providing safe, arsenic-free tap water for local consumption. This initiative addresses long-standing concerns regarding water quality in the region, where arsenic contamination has historically posed health risks to residents. By utilizing advanced filtration technology developed through the collaboration of these scientific institutions, the system aims to ensure that village-level water supplies meet safety standards for daily use.

For residents and long-term visitors in the Kok River area, this development represents a significant step toward improving public health infrastructure. Access to clean, treated water is essential for daily living, and this technology could potentially be scaled to other regions facing similar environmental challenges.

While the delivery of the prototype marks a successful milestone, further details regarding the long-term maintenance of these systems and the timeline for a broader rollout across all affected villages remain to be confirmed. Residents are encouraged to monitor local government announcements for updates on water quality improvements in their specific districts.
