Estudio de las condiciones de higiene en tanques de agua potable domiciliarios de la ciudad de Campana

Abstract

Con el objeto de verificar las condiciones de higiene de los tanques domiciliarios, receptores de agua potable proveniente de la red de distribución, se realizaron análisis bacteriológicos de la misma. En un total de treinta domicilios se extrajeron dos muestras; una proveniente de la red antes que ingrese al tanque y otra posterior al mismo; en cada una de ellas se tomó la precaución de esterilizar las bocas de salida y recipientes a fin de evitar aportes contaminantes externos. Los análisis se realizaron en el laboratorio microbiológico de la Facultad Regional Delta utilizando el método del número más probable (NMP). El 100 % de las muestras correspondientes al agua de red, desde el punto de vista microbiológico, era de óptima calidad, mientras que el 6,7% de las provenientes de los tanques domiciliarios revelaron contaminación, estando el 1,7% afectadas por coliformes fecales. Las muestras contaminadas correspondieron a tanques que no estaban en buenas condiciones de higiene, lo que indica la necesidad de resolver el problema mediante la concientización de la población en lo que respecta a adoptar medidas concretas de higiene.

Drinking water bacteriological tests were conducted with the objective of verifying sanitary conditions of home tanks, receptors of this drinking water which comes from the distribution system. Two samples were taken from a total of thirty houses; one of them was taken from the distribution system before coming into the tank, and the other sample was taken after coming into it; each time the outlets and containers were sterilized in order to avoid external contamination. The analysis were carried out at the microbiological laboratory of Facultad Regional Delta, using the method of the most probable number (NMP). From the microbiological point of view, 100 % of the samples that correspond to the water from the distribution system, were of an optimum quality, whereas 6.7 % of the water from the home tanks showed pollution levels, being 1,7 % affected by faecal coliforms. The polluted samples were taken from home tanks that were not in good sanitary conditions, which shows the need of solving the problem by making people aware that specific sanitary measures should be adopted.
