- Combined use of aquifer contamination risk maps and contamination indexes in the design of water quality monitoring networks in Mexico L. E. Barrón Romero I. Sandoval Montes J. A. Ramos Leal Ciencias de la Tierra water Vulnerability quality monitoring contamination index Three scenarios are analyzed where risk maps were developed as the initial stage in the design of groundwater qualitymonitoring networks. In the León Valley, the main potential source of contamination is a diffused source which corresponds to theurban area, where high vulnerability values and indexes of contamination have been recorded. In the river valley, the Turbio riverand a chromium processing plant stand out as potential sources of contamination. These sources are considered to be of the linearand point source type, respectively. The highest vulnerability values exist in the recharge areas, as well as in some areas inside thevalley. The highest contamination indexes are observed at the intersection of the potential source of contamination with areas ofhigh vulnerability. The third scenario is located in the region south of León, in the Penjamo-Abasolo graben, which is crossed bythe Turbio, Lerma and Guanajuato rivers. The rivers are considered linear sources, and occasionally diffused sources when therivers are in flood or irrigated with wastewaters. The highest vulnerability values are found in the main recharge areas. In thisregion the critical points are located at the intersection of highly vulnerable areas with the Turbio, Lerma and Guanajuato rivers.In each of these three scenarios the combination of three assessment parameters areas of high vulnerability, presence of apotential source of contamination, and high contamination indexes is presented as a first step in the design of groundwater qualitymonitoring networks. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843413 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.43
