Resumen:
Merida, Yucatan is the main urban centre of southeast Mexico. The ground characteristics and the waste management and disposal practices there result in a potential for contamination of the aquifer that is the main source for water supply purposes. The waste is composed primarily of food residues and a high content of organic matter which increase its biodegradable proportion. The hot climate prevailing in the area, and the humidity, increase the rate of putrefaction of wastes in such a way that within 24 hours of disposal they undergo an acidogenic phase, becoming adequate substrates for vectors that transmit diseases. Results indicate that groundwater underlying the waste disposal site is the most contaminated. The concentrations of studied contaminants increased considerably during the rain season because of leachate generation, dissolving salts from wastes and infiltrating down to the aquifer.
