RESUMO

Subterranean water is body water which can emerge by means of water fountains that are usually used for various activities by mankind. The objective of this study was to evaluate the potability standard of 12 water fountains in Taubatà city for human consumption. The parameters that were used for the evaluation were: bacteriological â counting of total coliformes (intestinal bacteria) and E. coli; physicochemical â concentration of turbidity and nitrate; parasitological â presence of Cryptosporidium spp and Giardia spp. The water samples were collected according to the established methodology by Standard Methods for the Examination of Water and Wastewater (APHA, 1998), in three stages in the year 2005. The results of the analyses, are in compliance with Portaria no 518 from the Ministry of Health in the year 2004 evidenced that the 36 samples of analyzed water, 67% were considered drinkable to the bacteriological standard, 92% were considered drinkable to the physicochemical standard and 100% were considered drinkable to the parasitological standard. Taking into account all the analyzed parameters in 3 collects, one concluded that 58% of the water samples from the studied water fountains were considered drinkable. One points out that during the study, it was not identified any kind of quality monitoring of the studied water fountains, which can endanger the populationâs health.
