Abstract

The irrigation system called “Pilzhum - Luis Cordero”, is located in the parish of Luis Cordero in the province of Cañar. The aim of this thesis was to determine the relationship between quality of irrigation water, quality of food production and its effect on the health of the beneficiaries of the irrigation system “Pilzhum - Luis Cordero”. For this study samples were taken of irrigation water in three points: Catchment Area in the sector of Chanin, Driving area in the sector of Santa Ana and in the area of distribution in the sector of Chocar; in addition five samples were analyzed of lettuce planted in plots located in each one of the communities that will benefit from the irrigation; also coproparasitarios reviews were conducted to 79 users of the system. It was found that the water of the irrigation system presents higher values to 1413,6 NMP/100 ml for total coliforms and values higher than the 80,9 NMP/100 ml of the fecal coliforms in the sectors of Chanin and Santa Ana; at the same time it was identified through the laboratory test that the lettuces are not suitable for consumption by presenting higher values to 1100 NMP/g of total coliform and 120 NMP/g of fecal coliforms. Based on the obtained results, it is concluded that the quality of irrigation water presents problems of pollution affecting crops and these in turn being carriers of parasites that is affecting the health of beneficiaries and consumers of the lettuce that are irrigated with water from the irrigation system
