AMBIENTALES73022019-08-23T21:17:28Z Temporal and spatial variation in the quality of surface water in the subwatershed of the Virilla river (Costa Rica) between 2006 and 2010 Variación temporal y espacial de la calidad de las aguas superficiales en la subcuenca del río Virilla (Costa Rica) entre 2006 y 2010 Herrera, Jorge Rodríguez, Susana Rojas, José F. Herrera, Éricka Chaves, María Costa Rica source apportionment water pollution Virilla Subbasin Contaminación de agua Costa Rica identificación de fuentes subcuenca del río Virilla In this work, we considered data of 25 water quality variables collected between January 2006 to December 2010 at 64 monitoring sites along the Virilla River Subbasin in Costa Rica. Factor analysis identified two potential pollution sources that explained 80.9% of the total variance in LP, two potential pollution sources that explained 77.1% of the total variance in MP, and two potential pollution sources that explained 67.8% of the total variance in HP. Most water quality variables were influenced primarily by pollution due to industrial wastewater, agricultural activities and urban runoff. Se analizaron los datos correspondientes a 25 variables de calidad de agua medidas en muestras recolectadas entre enero de 2006 y diciembre de 2010, en 64 sitios de monitoreo distribuidos a lo largo de la subcuenca del río Virilla, en Costa Rica. Mediante el uso de análisis de factor se lograron identificar dos fuentes potenciales de contaminación que explican el 80,9 % de la varianza total en zonas de baja contaminación, dos fuentes que explican el 77,1 % de la varianza total en zonas de moderada contaminación y dos fuentes que explican el 67,8 % de la varianza total en zonas de alta contaminación. La mayoría de las variables de calidad de agua fueron influenciadas principalmente por la contaminación debida a aguas residuales industriales, actividades agrícolas y descargas urbanas.
