Resumen
Los estuarios están contaminando mayormente por el ser humano, unos de los factores
de polución son las bacterias que alteran las condiciones físico-químicas del lugar. El
objetivo del presente trabajo fue determinar la concentración de Coliformes totales y
Escherichia coli en el estuario de Chulluype, en la provincia de Santa Elena. Se realizó
la recolección y transporte de 5 muestras colectadas aleatoriamente en diferentes
puntos del estuario. Se determinó los niveles de concentración de microorganismos y
los resultados se compararon con los límites máximos permisibles establecidos en el
ANEXO 1 Del libro VI del Texto Unificado de Legislación Secundaria del Ministerio del
Ambiente (TULSMA). Se obtuvieron valores máximos de Coliformes totales de 4x107
NMP/mL, que sobrepasaron los límites permisibles. Con relación a E. coli se obtuvieron
valores 2x102 UFC/mL en las concentraciones y no superaron los límites permisibles.
Finalmente se propuso una fitorremediación, para recuperar las condiciones naturales
del lugar.
The estuaries are contaminating mainly by the human being, one of the factors of pollution are the bacteria that alter the physical-chemical conditions of the place. The objective of the present work was to determine the concentration of total coliforms and Escherichia coli in the Chulluype estuary, in the province of Santa Elena. Collection and transport of 5 samples collected randomly at different points of the estuary was carried out. The levels of concentration of microorganisms were determined and the results were compared with the maximum permissible limits established in ANNEX 1 of Book VI of the Unified Text of Secondary Legislation of the Ministry of the Environment (TULSMA). Maximum values of total coliforms of 4x107 NMP / mL were obtained, which exceeded the permissible limits. In relation to E. coli values were obtained 2x102 CFU / mL in the concentrations and did not exceed the permissible limits. Finally, a phytoremediation was proposed, to recover the natural conditions of the place.
