Pollution Crisis in Colombia's San Silvestre Wetlands Attributed to Landfill Operations
Local fishermen report alarming ecological degradation as contamination from a landfill operated by Veolia raises health concerns.
In the San Silvestre wetlands of central Colombia, residents and local fishermen are experiencing a significant ecological crisis, which they attribute to pollution emanating from a landfill operated by the French waste management company Veolia.
Wilson Díaz, president of a fishing union in Barrancabermeja, describes deteriorating water conditions, stating, "It smells foul," as he assesses the effects of pollution on his lifelong fishing grounds.
For years, scientific studies, environmental advocacy groups, and local fishermen have voiced concerns about the contamination of the wetlands, a protected area crucial for biodiversity in the department of Santander.
The landfill, which operates on 30 hectares and has been under Veolia's management since 2019, reportedly receives around 150 tonnes of waste daily from Barrancabermeja, an area heavily influenced by oil production activities.
Concerns heightened after a recent report by the environmental NGO Global Witness, which accused Veolia of illegally discharging leachate, a toxic liquid waste residue, into local streams and waterways.
This action has reportedly led to the presence of hazardous heavy metals, including mercury at levels 25 times above safe limits, in sediment samples taken from water sources near the landfill.
The pollution crisis has had a devastating impact on local fisheries.
Díaz recounted how his daily catch has diminished drastically, from an average of 200 fish to as few as 15. He warns that the fishing community is on the brink of displacement due to the ongoing environmental degradation.
Similar sentiments have been echoed by local health officials, who have reported rising health issues, including high incidents of birth defects such as anencephaly, in newborns within nearby communities.
Local doctor Dr. Yesid Blanco cited unusual cases of skin conditions among newborns as further evidence of the health crisis tied to pollution in the wetlands.
Veolia has issued strong denials against the allegations presented by Global Witness, asserting that its operations comply with environmental regulations and claiming that the pollution predates their management of the landfill.
The company claims that leachate generated onsite is treated before being reused for irrigation and other infrastructural needs within the landfill.
Veolia representatives also argue that the environmental issues faced by San Silvestre are not solely attributable to their operations but also involve broader regional activities such as oil extraction and agricultural practices.
Multiple environmental studies and local community testimonies counter Veolia's claims, with residents of Patio Bonito sharing troubling accounts of alarming odors, increased insect populations, and chronic health problems since the landfill's establishment.
Himelda Arias, a long-time resident, expressed despair over her community's transformation under the influence of the landfill, citing the damaging impact on both health and local wildlife.
"The stench of rubbish is just dreadful.
The landfill is slowly killing us," she remarked.
As the conflict between local communities and the waste management company continues, environmental groups and scientists have called for rigorous inspections and immediate intervention to safeguard the San Silvestre wetlands and surrounding ecosystems.
The situation underscores the growing tension over waste management practices and environmental preservation in Colombia, reflecting a broader global challenge of balancing industrial operations with community health and environmental protection.
