RESUMEN: Se usaron técnicas de análisis estadístico multivariado, para determinar la variación temporal y espacial de la calidad del agua en la zona costera de Santa Marta, donde se ubica un emisario submarino que descarga 1 m3/s de aguas residuales domésticas. La ANOVA de dos vías, los análisis de clúster y de componentes principales mas la interpolación de krigging, fueron considerados para este análisis. En la variación temporal se encontraron diferencias que marcan en el año dos periodos de tiempos heterogéneos, de diciembre a abril la concentración de los parámetros de calidad del agua es más alta. El resto del año (mayo, junio, agosto, noviembre, exceptuando el mes de julio donde se presentaron concentraciones altas), se registran concentraciones sensiblemente inferiores. En la variación espacial se reportan dos grupos de áreas en las cuales la calidad del agua es diferente, dicha diferencia está relacionada con la cercanía a la descarga del emisario submarino.
ABSTARCT: Multivariate statistical techniques were used to investigate the temporal and spatial variations of water quality at the Santa Marta coastal area where a submarine outfall that discharges 1 m3/s of domestic wastewater is located. Two-way analysis of variance (ANOVA), cluster and principal component analysis and Krigging interpolation were considered for this report. Temporal variation showed two heterogeneous periods. From December to April, and July, where the concentration of the water quality parameters is higher; the rest of the year (May, June, August-November) were significantly lower. The spatial variation reported two areas where the water quality is different, this difference is related to the proximity to the submarine outfall discharge.
