| Descripción: | In recent years, the Gulf of Papagayo has been experiencing accelerated socio-economic development that may be putting pressure on its natural spaces and resources, contributing to the deterioration of its marine-coastal zone. The objective of this study was to identify the main terrestrial sources of pollution that may have negative effects on the environment and the hygienic-sanitary quality of the waters at its beaches. In order to collect information on the production and management of solid and liquid waste, generated by the socio-economic activities carried out in the coastal districts of Nacascolo and Sardinal, 81 surveys were applied to commercial premises during 2016 and 2017. In addition, four water samples were taken from different beaches. Results indicate that 76% of the commercial establishments and 50% of the hotels dispose of solid waste through the municipal garbage collection system, while 24% of the shops and 81% of the hotels use septic tanks for disposal of sewage. This is due to the fact that, because of the nature of these activities, the waste generated is considered ordinary. Regarding the concentrations of fecal coliforms, three categories were established in order to determine the hygienic-sanitary quality: excellent (<10), good (10-100), and regular (101-240). In the case of Enterococcus, its concentration indicates that all beaches are suitable for recreation. In general, the concentrations of these two parameters increased mostly during the rainy season, probably due to surface runoff. |
