Resumo

Agriculture is one of many human activities that influence groundwater quality through the use of fertilizers and pesticides.A ground water monitoring study was carried out in the southern region of the state of Yucatan. Twelve wells were sampled once a month over one year: The concentration of nitrates and sulfates in four wells were above the 22.5 and 250 mg/l maximum permitted under Mexican regulations. A multivariate discriminant analysis, applied to the data from the agricultural area and other regions which have different land use, showed that groundwater quality has been influenced by fertilizer use.
