Evaluation of the Microbiological Contamination Present in La Carolina and La Totora Streams Located in Gral. Alvarado, Country Buenos Aires, Argentina.

Abstract

Fecal contamination of surface water is a problem which directly affects human health. The most significant indicator of disease risk from surface water is Escherichia coli. The objective of this paper was to evaluate environment contamination and sanitary risk in La Carolina and La Totora streams, between July 2016 and June 2017, using total coliform, fecal coliform, E. coli and Enterococcus faecales as indicators. Analysis were done according to the methods described in the Standard Methods. Result were similar in both streams, presenting the highest enumeration in January, February and March of 2017. Although, results do not present relevant data, it can be concluded that in most of the samples, the results of fecal coliform, E. coli and Enterococcus faecales were higher than the guide values from the ADA resolution 42/06.
