Update 21 April: Sanidad has given the all clear for water to be consumed in all the municipalities affected by yesterday’s diesel spill in north Tenerife. All the tests have apparently now been completed and Sanidad says that water can now be used for cooking and personal hygiene and, most importantly, for drinking. The municipalities that had been affected were Santa Úrsula, La Victoria de Acentejo, La Matanza de Acentejo, El Sauzal, Tacoronte, La Laguna and Santa Cruz.
Update 9pm: Seprona, the Servicio de Protección de la Naturaleza de la Guardia Civil, has imputed (named as a formal suspect) a 55-year-old man on suspicion of polluting consumer water in north Tenerife with diesel. The Guardia Civil says that the man was trying to repair a vehicle in the Pino Soler area when a pipe broke, releasing an indeterminate number of litres of diesel into the water supply. Three municipalities, Santa Ursula, La Matanza and La Victoria are still under safety restrictions, says Sanidad.
Update 4pm: Teidagua says the water in the municipalities of La Laguna and Tacoronte can now be used without restrictions.
Original post 20 April: An accidental diesel spill in the Santa Cruz Aguamansa canal has resulted in Sanidad issuing water warnings to six municipalities in north Tenerife. The affected areas are Santa Úrsula, La Victoria, La Matanza, El Sauzal, Tacoronte and La Laguna. Water was shut off to the canal the moment the spill was discovered and it remains closed, said Sanidad. There will have to be considerable cleaning and checking carried out to the installations, particularly in Santa Úrsula, La Matanza and La Victoria de Acentejo, before the all clear can be issued. Please note that this warning is not just for drinking water, but also for cooking, food preparation, and personal hygiene. Santa Cruz, at least at present, is not affected by Sanidad’s safety restriction.
