HERNANDEZ GARCIA, Jesús. Water potability in San Juan y Martinez aqueducts. Pinar del Rio province. 2009-2010. Rev Ciencias Médicas [online]. 2012, vol.16, n.3, pp.39-50. ISSN 1561-3194.

A longitudinal-descriptive, prospective research was conducted at “Hoyo de Mena and Hermanos Saiz” aqueducts in San Juan y Martinez during January 2009 to December 2010, where the quality of water was characterized following laboratory examinations in water-supply networks. By means of this research the hygienic quality of water was assessed through bacterial and physical-chemical examinations; which water is supplied by both systems in the Popular Councils under studies. The quality of water supplied by “Hoyo de Mena (81%) and Hermanos Saiz (78%)” presented a poor quality during 2009 respectively, due to the unstable availability of chlorine and ruptures of chlorination equipments, mainly at “Hermanos Saiz”, because of the deficiencies already mentioned during 2010; 81,9% of potability and 90.6% in the Urban Popular Council. This study also evaluated the water supplied by these systems that during the period presented a poor quality as well. Charts were prepared to show the results; using also the statistical calculation of X2 with a significance level of 95%.
