What Happened
The Ministry of Health (MINSA) has warned residents in parts of Los Santos province that tap water in the corregimiento of Llano de Piedra and in the district of Las Tablas is not fit for human consumption. The advisory asks the population to boil tap water for three to five minutes before drinking it.
Health Advisory
MINSA’s announcement is a precautionary public-health measure. Authorities specifically recommend boiling water from household taps for three to five minutes prior to consumption to reduce the risk posed by microbial contamination identified in recent tests.
Cause and Testing
The advisory follows water-quality measurements performed by the National Institute of Aqueducts and Sewers (IDAAN) and verified by MINSA. Those tests indicated changes in water-quality parameters and the presence of microorganism loads outside normal ranges, prompting the advisory. MINSA did not provide further technical details in the notice published on March 20, 2026.
What This Means
Residents of Llano de Piedra and Las Tablas should treat tap water as potentially unsafe until authorities lift the advisory or provide updated test results. Boiling water for three to five minutes is a commonly recommended method to inactivate bacteria and many other pathogens; however, it does not address chemical contamination, which was not reported in the MINSA notice.
Next Steps and Information
MINSA and IDAAN are the agencies responsible for monitoring water quality and informing the public. The ministry’s verification of IDAAN tests triggered the public warning. Residents should watch for further announcements from MINSA or local IDAAN offices for updates on test results and on when tap water is again considered safe for routine consumption.
