Through a field, descriptive and transverse study, it was determined the presence of intestinal helminthes in the water of 10 houses and the physical-chemical and parasitological analysis of a deep well water for human consumption in the "18 de Mayo" community, "Francisco Linares Alcantara" municipality, Aragua state. On samples of 20 liters by duplicated from the houses and the well, it was applied a concentration technique of floculation, to realize direct observation using saline solution and lugol. It was observed presence of helminthes eggs in 60% of the analyzed houses, finding: eggs of Ancylostomideos sp. (30 %), Trichuris trichiura (20%) and Ascaris lumbricoides 10 %. In the well, it was not found the presence of intestinal helminthes and its physicalchemical analysis was within the references values with the exception of chlorine that was absent in the analysis, which is indicative of the fact that is not getting the proper treatment. Parasitic infections caused by helminthes can be acquired through the consumption of contaminated water and food with fertile eggs or infective larvae L3, in this regard it is important to verify their presence in the water and monitor the conditions of integrity of the network of distribution toward homes.
