Resumen
La presente investigación se realizó en el espacio urbano costero El Coco, perteneciente al distrito de Sardinal del cantón de Carrillo, en la península de Nicoya, el cual muestra un acelerado creci-miento orientado a la actividad turística, con el consecuente incremento en el consumo del recurso hídrico. Esta situación conlleva a una alta vulnerabilidad a la contaminación del acuífero El Coco. Se identificó y caracterizó los pozos potencialmente vulnerables a la contaminación y se correla-cionaron con el Mapa de vulnerabilidad a la contaminación (GOD). Asimismo, se determinaron las áreas de Protección Perimetral de Pozos (PPP) y de las zonas de captura o de carga de pozos (ZOC).Se utilizaron como fuentes primarias entrevistas abiertas. Se emplearon técnicas de fotointerpreta-ción y teledetección, y la aplicación Sistemas de información Geográfica (SIG).
This research was conducted in the El Coco coastal urban area belonging to the Sardinal District of the Canton of Carrillo in the Nicoya Peninsula, which shows rapid growth in tourism-related activity and the subsequent increase in water resource consumption. This situation leads to a high vulnerability of contamination to the El Coco aquifer. Wells potentially vulnerable to contamination were identified and characterized and correlated with the map of vulnerability to contamination. Likewise, areas of Perimeter Protection Wells were identified along with capture or well-loading zones. Open interviews were used as primary sources. Photo interpretationand remote sensingtechniques were employed along with Geographic Information Systems
