Abstract: Parameters such as Total Organic Carbon, nitrate ion, nitrite ion and metals were determined according to conventional methods of chemistry in our different laboratories. The following average concentrations were obtained in the waters: total organic carbon (5.44 mg / L at 12.59 mg / L); nitrate ion (12mg / L at 70mg / L); the nitrite ion (0.2 mg / L to 1.2 mg / L); ortho-phosphate (0.07 mg / L to 1.4 mg / L); Chromium (2μg / L at 15.21μg / L); Copper (2 μg / L at 5.6 μg / L); Arsenic (2.1 μg / L at 17.2 μg / L) and Cadmium (0.9 μg / L at 8.26 μg / L); Aluminum (8.67μg / L at 15μg / L); potassium (9.9 μg / L at 22.11 μg / L); Lead (1.35μg / L at 11.02μg / L). For sediments, the following assessment values were obtained after calculating the Enrichment Factor (EF) and the Geoaccumulation Index (I-geo): for EF (1.07 to 10.0), 56) and I-geo (2.22 to 8.70).
