The assessment of the extent of pollution was undertaken by the use of the Mexican Residential Soil Guideline Values, the calculation of the contamination factor and the pollution load index. The results showed concentrations of heavy metals below the Mexican guidelines in the city, except for chromium and lead in a few samples. However, using the contamination factor the concentrations for chromium, lead and copper are exceeded in some samples. The map of pollution load index shows the areas requiring immediate attention from the decision makers. 2019 artículo científico 1405-7743 https://www.redalyc.org/articulo.oa?id=40465052003 https://www.redalyc.org/journal/404/40465052003/ https://www.redalyc.org/journal/404/40465052003/html/ https://www.redalyc.org/journal/404/40465052003/40465052003.epub https://www.redalyc.org/journal/404/40465052003/movil 10.22201/fi.25940732e.2019.20n3.027 en http://www.redalyc.org/revista.oa?id=404 Ingeniería.
