The city of Casilda, in the south of Santa Fe, was enveloped in a strong environmental concern after residents detected the water of the Canal Candelaria dyed red by the discharge of blood and cattle waste.
The incident, recorded in videos that went viral on social media, showed sections of the canal—known as “the ditch”—with an intense reddish coloration, compatible with waste from the meat industry.
Residents claimed that this would not be an isolated episode and that this type of pollution has been recurring for some time. Suspicions point to establishments linked to meat processing and animal slaughter, although no company has been officially identified yet.
Criminal complaint and neighborhood demand
The situation led to a criminal complaint to investigate the origin of the waste and determine responsibilities for the environmental damage. Lawyer Juan Pablo Castagna appeared as a plaintiff in the Prosecutor’s Office, warning that the contamination of water resources puts the aquifers at risk, a source of consumption for the citizens of Casilda.
The text of the complaint emphasizes that exposure to these discharges represents a direct danger to public health, with children being a particularly vulnerable group. Furthermore, urgent intervention by the competent authorities was demanded to prevent similar future episodes.
Health and environmental risks
The concern focuses on:
- Aquifers: risk of contaminant infiltration into drinking water sources.
- Public health: exposure to pathogens and toxic substances that can cause serious diseases.
- Environmental impact: degradation of urban ecosystems and loss of aquatic biodiversity.
Specialists took water samples to analyze the discharged substances and assess the extent of the pollution.
Global river crisis
The case of Casilda reflects a broader issue: the pollution of rivers and urban watercourses. Globally, the main factors are:
- Untreated industrial and sewage discharges.
- Agrochemicals and fertilizers that seep into aquifers.
- Plastic waste and microplastics, like those detected in the Paraná River near Rosario.
- Heavy metals from mining, as occurs in the Rímac River (Peru) or the Napo (Ecuador).
The side effects include the bioaccumulation of toxins in the food chain, an increase in resistant bacteria, and eutrophication, which depletes oxygen and destroys local fauna and flora.
Social demand and need for controls
The episode generated a strong neighborhood demand for greater environmental controls and once again put the impact of certain industrial activities on Santa Fe’s urban watercourses under scrutiny. The lack of oversight and non-compliance with environmental regulations turn many rivers into open-air sewers, with direct consequences for health and the environment.
The contamination of the Canal Candelaria in Casilda is an emblematic case of how the lack of industrial controls can jeopardize public health and water resources. The criminal complaint and neighborhood pressure seek to ensure that authorities act quickly and transparently.
In a global context of water crisis, protecting urban watercourses is vital to preserve biodiversity, ensure access to drinking water, and prevent episodes like this from recurring.
