Investigaciones sobre contaminación en agua potable en tanques y cisternas del distrito de San Isidro / Investigations on pollution in drinkable water in tanks and cisterns of San Isidro's district

ABSTRACT

The presence of Clostridium perringens as an indicator of faecal contamination was evaluated in drinkable water stored in dippers and reservoirs. 100 samples (50 from dippers and 50 from reservoirs) were tested, finding out presence of C. perfringens in 7 samples from reservoirs, within a value from 10 t 70 cfu/ml. The results from the evaluation of samples from dippers indicated no presence of C. perfringens. It was suggested the inclusion of the evaluation of presence of C. perfringens in routine bacteriological evaluation of drinkable water.
