A recent study performed by El Laboratorio Nacional de Aguas, de Acueductos y Alcantarillados (AyA) shows that the level of coliforms in the beach water for every 100 milliliters of water is down from 800 in 2007 to 100 this year. Darner Mora, laboratory director, said that in 2007 corrective measures began. For example, AyA took Tamarindo’s Ecological Blue Flag away, and the Health Ministry sited 80 sanitary infractions to commercial establishments. “It is evident that the actions taken by the community and the government entities have worked,” he said.
The study was made during parts of 2008 and 2009 with samples taken from 8 different points in front of the main hotels. Ricardo Sancho, AyA president, pointed out the interest of the Tamarindo residents to reduce the water contamination. “As we were, at the moment, severe and critical in respects to the beach, at times creating anger among hotel owners, today we have to recognize the progress and say to the people that they can swim there without major problems,” he said.
