Resumen:
Groundwater is one of the main supply sources of drinking water in Mexico, as they support a poor biological community, because of their low contain of nutrients However in the recent years, human activities and urban growth are the main factors of aquifer contamination Therefore, water may contain chemical contaminants and microorganisms that can cause several diseases, such is the case of free-living amoebae (FLA) The objective of this research is to determine the microbiological quality (total conforms, fecal conforms and free-living amoebae) of Zacatepec aquifer, in the state of Morelos Monthly samplings of thirteen wells of the aquifer were carried out during one year The following physicochemical parameters were measure in situ pH, dissolved oxygen (DO) and temperature Total and fecal conforms were determined by the membrane filter technique Free-living amoebae were cultured on non-nutritive agar medium (NNE), the identification was carried out taking in account their morphologic
