    The activities man performs in the environment must be known and regulated in order to carry out correct planning and management of resources. Remote sensing allows the assessment of natural resources and their current problems faster and more efficiently. The present study was conducted in the Valle del Mezquital, in the state of Hidalgo, which has problems of pollution from wastewater used to irrigate farmlands. Land was evaluated and classified by level of nitrate concentration, detected through Landsat-TM satellite images, the IDRISI program, and field data. The results indicated that through satellite images it is possible to recognize nitrate concentrations in soil layers up to 60-90 cm deep, where high nitrate concentrations are directly associated to soil lixiviation and cause problems of pollution. When alfalfa is used as nitrate indicator, the satellite image shows nitrate concentrations with 91.88 % certainty; in the case of corn, the image only presents 63.33 % certainty.

    Keyworks: satellite image, nitrates, lixiviation, wastewater.
