Remediating Water and Territory in Suroriente

Decades of conflict left land and water bodies in Colombia’s Puerto Vega–Teteyé corridor scarred by oil spills caused by illegal armed groups. Though the damage predated its presence, Gran Tierra took action to address the long-standing contamination.

Since launching a major remediation effort in 2022, GTE has rehabilitated 67 hectares across ten villages to make sure that area residents no longer bear the burden of past environmental harm. The Suroriente Clean-Up, a partnership between Ecopetrol and Gran Tierra Energy, reflects the companies’ shared commitment to environmental clean-up and waste collection from third-party spills and social responsibility.

Aligned with Colombia’s national remediation strategy, the project has also created 215 local jobs, engaging property and business owners in hands-on environmental cleanup—building skills that will benefit the region for years to come.

In many rural Colombian villages, untreated wastewater flows through open sewers, creating serious health and environmental risks—especially during […]
