Overview
- Conagua issued a preventive alert after a cargo truck dumped aluminum sulfate into the Canal Alto, stopping use of canal water and the El Cocoraque stream for any human activity, and authorities said the driver fled with no injuries reported.
- The Antonio Rosales water treatment plant is shut down and OOMAPAS is delivering drinking water by tanker to nearby neighborhoods, including Antonio Rosales and El Sifón.
- Agricultural irrigation is paused across affected areas to keep the chemical out of fields and protect crops from contamination.
- Crews closed canal gates and routed controlled discharges through the El Cocoraque to push the polluted water toward the sea and speed flushing.
- Officials are sampling the water around the clock, with high concentrations at the spill point so far and an expectation that levels will fall as flows dilute the plume in the coming days.
