Latest incidents

A feature on wastewater infrastructure, sewage discharges into the sea, coastal pollution and tourism in Tenerife, referring to the Stop Vertidos al Mar platform, the Punta Brava outfall, the closure and reopening of Playa Jardín, and official figures on discharge points in the Canary Islands. MiCharco records it as island-wide context, not as a new closure or contamination incident.

The bathing area returned to operation with a yellow flag. The municipality reported a small surface oil patch likely related to sea conditions, while no bathing prohibition was issued by the health authority following routine sampling.

Bathing was temporarily prohibited after dead fish, oil and floating marine debris were observed in the bathing area. Samples were taken to assess water quality and the material present.

A visible white patch was reported in the water at Las Teresitas and attracted the attention of bathers. The event was reported by local media.

Playa Jardin officially reopened after almost a year closed, following improvements to wastewater and sanitation infrastructure and confirmation from Public Health that the bathing water met suitable conditions.

The beach reopened after cleaning and disinfection work was completed and water analysis confirmed conditions suitable for bathing.

Playa de San Marcos was temporarily closed after an unexpected shutdown and collapse at the local wastewater treatment plant caused a discharge in the promenade area. The plant subsequently returned to operation and cleaning and disinfection work was carried out.

Bathing reopened after new analyses confirmed that water quality was again suitable for bathing following the temporary closure caused by elevated faecal-bacteria levels.

Bathing reopened following satisfactory follow-up analyses.

Temporary bathing prohibition following adverse microbiological results.

Beach closed to bathing again following adverse microbiological results.

Bathing reopened after follow-up analysis confirmed suitable water quality.

Bathing reopened after counter-analysis confirmed that the water was again suitable for bathing.

Temporary bathing prohibition following adverse bathing-water analyses.

Temporary bathing closure after analyses detected E. coli above the permitted maximum.

A large brown patch was reported offshore affecting the Playa de Las Américas and Troya coastline. A marine scientist described it as a major discharge, while the Cabildo stated that the visible water came from saline groundwater released during drilling works and denied that it was wastewater. Bathing was not prohibited.

A large brown patch, reported as a likely accumulation of algae, was observed approaching the coastline near Playa San Juan and Los Gigantes. No bathing prohibition or confirmed wastewater contamination was reported.

Residents reported a large patch of brown foam and dozens of small dead fish along the Puerto de la Cruz coastline, around the Punta Brava treatment plant and towards Martiánez. The municipality sent local police and technical staff and, in its assessment, attributed the foam to rough sea conditions and the dead fish to catch discarded by a fisherman, without adopting a new preventive bathing measure. The episode occurred while Playa Jardín was already affected by the separate 2024-2025 long-duration closure, and MiCharco records it as an observational report, not as a new confirmed fecal contamination incident.

The affected section reopened after follow-up analyses returned normal bathing-water values.

A section of Las Teresitas was temporarily closed to bathing after routine monitoring detected a short-duration water-contamination episode.

Reporting two days later still described the red flag at both bathing areas. No official reopening date has been located, so MiCharco keeps this episode as historical and not as a restriction currently in force.
