The nation’s environmental tribunal Monday froze commercial activity at the Estación de Servicio Lago Arenal after it received reports of fuel spills contaminating the aquifer that serves the community of Tilarán.
The Tribunal Ambiental Administrativo said that a private well some 4 kilometers from Tilarán showed contamination and that persons using that well had to be provided water trucked in by the Instituto Costarricense de Acueductos y Alcantarillados.
It was the institute, the nation’s prime water provider, that filed
the complaint. The tribunal cited the grave risk of contaminating the entire aquifer.
The aquifer is some 106 meters below ground, and the tribunal received reports of diesel fuel being found in small quantities in the water.
The tribunal also ordered an immediate study of the gasoline station’s tanks and the creation of a plan of remediation within 30 days.
Acueductos y Alcantarillados provides the water service to Tilarán.
