The General Directorate of Emergencies of the Government of the Canary Islands has activated in PLATECA alert situation due to a marine pollution incident affecting the coastline between Telde and Mogán. The decision, in effect since 19:00 p.m. on Thursday, is in response to the presence in the sea of decomposing organic matter, detected offshore from the coast of Telde.
The warning affects six municipalities in the east and south of the island —Telde, Agüimes, Ingenio, Santa LucÃa de Tirajana, San Bartolomé de Tirajana and Mogán— and aims to coordinate actions, monitor the evolution of the phenomenon and minimize potential impacts on public health and the marine environment, after the extent of the spill was confirmed by the currents.
What has happened and why has the alert been activated?
The alert is issued following the appearance of a stain formed by decomposing organic waste originating from offshore aquaculture facilities. According to operational information, PLATECA is activated to centralize the response, improve data exchange and accelerate decision-making between administrations.
The wind and sea conditions of the last few days would have favored the movement of the episode towards the southeast and south of Gran CanariaThe substance is observed discontinuously on the surface, with a variable appearance depending on the state of the sea, which requires dynamic monitoring of the affected areas.
Municipalities affected and the state of the beaches
The alert covers a wide stretch of coastline where measures have been implemented preventive measures closure of the bathing area and increased surveillance. The restrictions are adapted to the evolution of water quality parameters and the presence of surface remains.
- Municipalities on alert: Telde, Agüimes, Ingenio, Santa LucÃa de Tirajana, San Bartolomé de Tirajana and Mogán.
- Beaches with recent closures: Vargas (Agüimes), Las Burras and San AgustÃn (San Bartolomé de Tirajana), as well as Melenara and Salinetas (Telde), the latter by preventive recommendation after detecting surface remains.
- Favorable development in Melenara: The experts point to a possible reopening if things remain the same stable values at the controls.
Local authorities, in coordination with the regional government, are prioritizing signage, user information, and targeted cleaning tasks where deemed effective and safe, always under technical criteria.
What the analyses say and the possible origin
The Telde City Council has released the results of independent sampling carried out in mid-October on the municipal outfall and the sewage network. According to these tests, No chemical spills detected nor abnormal concentrations of heavy metals, with values ​​remaining within the usual parameters in previous records.
While environmental groups have pointed to the offshore aquaculture As a possible source of the incident, the company affected by the fish kill attributed it to a chemical-appearing spill. However, the municipal inspections They show no evidence of failures in local sanitation facilities, and the dominant operational hypothesis maintains the focus on decomposing organic matter.
Surveillance and coordination device
With PLATECA on alert, the regional government is coordinating resources with the Island Council, the municipalities, Public Health, the Maritime Authority and Maritime Rescue to monitor the stainto delimit its scope and reduce impacts. Maritime and aerial resources have been activated for the monitoring and sampling, including surveillance between ArguineguÃn and the Maspalomas lighthouse after the detection of a new area of ​​interest.
The priority is to protect the public health and environmental safety, with constant updates as laboratory analyses and field reports are processed. The alert status will be maintained until new notice depending on how the episode unfolds.
Recommendations for people using the coast
Authorities are urging caution and asking people to stay informed through [unclear - possibly "source of information"]. official channels before visiting potentially affected beaches, especially in areas where temporary closures or restrictions have been implemented.
- Respect the signs and the instructions of the security personnel.
- Avoid bathing in areas with Red flag or visible presence of waste.
- Check the notices of Public Health and from your local council to find out the water conditions.
- Notify Canary 112 any relevant observations (strong odor, surface stains).
European regulations and context
In Europe, the management of episodes of this nature is framed within the Bathing Water Directive and legislation on water and waste, as well as good practices in aquaculture to minimize escapes and organic byproducts. These rules strengthen surveillance systems, risk analysis, and public information during coastal incidents.
The activation of PLATECA concentrates the response under a single command; the beaches remain under continued observation And initial analyses rule out municipal chemical contamination, while the organic nature of the episode is confirmed and progress is being made towards safe reopenings where the indicators allow it.
