NOTAS DE LA VARIABLE
| Porcentaje de sitios de monitoreo en cuerpos de agua superficiales que miden SST, según el nivel reportado de calidad del agua. |
SST: Sólidos Suspendidos Totales. Indicador que se utiliza para determinar la cantidad de sólidos suspendidos totales en cuerpos de agua superficial, provenientes de las aguas residuales y la erosión del suelo. El incremento de los niveles de SST hace que un cuerpo de agua pierda la capacidad de soportar la diversidad de la vida acuática. Los valores de SST se expresan en mg/l; de acuerdo con este indicador, los niveles de calidad del agua son los siguientes: Excelent e, si: SST <=25 Buena, si: 25 < SST <=75 Aceptable, si: 75 < SST <=150 Contaminada, si: 150 < SST <=400 Fuertemente contaminada, si: SST > 400 Simbología: "<", menor que;" >", mayor que; "<=", menor o igual que. |
