MORA ALVARADO, Darner Adrián. Sanitary Conditions of Beach Waters in Jacó: Costa Rica 1986-2008. Rev. costarric. salud pública [online]. 2009, vol.18, n.1, pp.5-9. ISSN 1409-1429.

Objective: To study sanitary conditions of beach waters in Playa Jacó through sanitary inspection and samplings for the period 2002-2008, as compared to results of the periods 1986-1987 and 1996-2000. Method: First, an analysis was performed on the historical evolution of the quality of the beach in the periods 1986- 1987 and 1996-2000; then the annual geometrical average, the minimum and the maximum of fecal Coliforms/100mL (CF/100mL) were analyzed for the period 2002-2008. The evolution of the quality of the water was done under "National Bacteriological Criteria to Evaluate Seawater in Direct Contact (swimming) "where the limit for seawater is established as 240CF/100mL: furthermore, surface water quality was studied at the four mouths of the rivers (three brooks and Copey River). Results: Data indicate an increase of fecal contamination of the seawater of Jacó Beach during the last two decades. This situation became worse in the year 2008, as shown in sampling of two different points. These sampling points were classified as not acceptable for swimming. Furthermore, high density of fecal coliforms was identified in the three brooks and the Copey River. This situation is linked to the use of septic tanks and has an influence in the poor quality of the beach. Discussion: The urban and tourist growth in the zone in a disorderly fashion has affected the sanitary quality of the beach, classifying it in 2005 and 2008 as class E and D, respectively; that is to say, at the moment this beach is "non-acceptable for swimming".
