Guatemala investigates Las Vacas River after red discoloration

The Las Vacas River in Guatemala has recently turned red, prompting an investigation by the Ministry of Environment to determine the origin and nature of the substance causing the discoloration.

While the red color is a new visual phenomenon, the river has faced long-standing contamination issues. Previous assessments have identified high levels of fecal coliforms, Escherichia coli, nitrogen, and phosphorus. Reports indicate that the river has struggled with minimal aquatic life and significant sewage discharge for years.

This incident highlights broader systemic issues in Guatemala's water management. Data from the Ministry of Environment and Natural Resources suggests that approximately 69% of reported wastewater discharges remain untreated, reflecting a decades-long struggle with inadequate sewage infrastructure and treatment capabilities.
