    The purpose of this research was to evaluate the arsenic concentration in the Central Canal Toacaso irrigation system, located in the Cotopaxi province in the Latacunga canton, which is made up of 325 users, who are divided into eight modules.The characterization of the production systems was carried out using three participatory diagnosis tools; Dialogue with key informants , Map of resources and land use, Seasonal calendar of cultivation. The arsenic concentration in water and soil was evaluated by the Ecuadorian regulation, Anexo1 (water) Anexo2 (soil); and INEN9 standards for the comparison of meat and milk samples. The irrigation board is made up of the president (Mr. Ramiro Vela), vice president (Mrs. Fabiola Campaña), treasurer (Mr. Armando Monga), water distributor (Mr. Julio Catota). The distribution of water in the Junta is carried out by six branches: El Pueblo (57.67 ha), R. Cuicuno (98.10 ha), R. Cruz 1 (66.90 ha), R. Cruz 2 (56.28 ha), R. Yugsiche (69.87 ha) and R. Calera (18.78 ha), which make up the eight modules. The agricultural production system is based on the cultivation of forage mix (grasses), corn, alfalfa, carrots, and onions, while livestock production involves the sale of milk and the raising of animals for consumption and commercialization. The sale of milk constitutes 40% of their economic income, 60% is formed by the sale of beef cattle, guinea pigs and agricultural products from the area. The results of the water analyzes in the Bocatoma, junctions of two rivers (Río Blanco and Pucahuaico), the reservoir, and the alfalfa field (sprinkler irrigation) determined that the levels of arsenic exceed the permissible limit according to the TULSMA regulations (water irrigation), 0.1 mg/l. On the other hand, the arsenic levels in the soil are elevated compared to the regulations, with an average of 20.22 ppm, which exceeds the limit of 5 ppm specified in Book 6 of the TULSMA regulations. At the same time, the arsenic concentration in the crops (corn, alfalfa, carrot) is reflected in higher levels in their roots, with averages of 16.3 mg/kg, 7.37 mg/kg, and 2.71 mg/kg, respectively; however, the results of the meat and milk analyses show a result of 0 ppm, which does not exceed the permissible limit of 0.01 ppm according to INEN 9 regulations. indicating that there is no detectable presence of arsenic, this can given because arsenic is absorbed through the liver and tissues, so that by going through this whole process it is eliminated
