| Abstract: | Groundwater quality in the city of Merida, Yucatan, Mexico, where dependence on groundwater supply is 100%, is affected by
urbanization. Data from the sampling of shallow wells and boreholes along with water level records are used to study the aquifer.
Chemical changes in time of the bottom and top half of the freshwater zone are the basis for hydrogeochemistry. The comparison
of 1970 data (which represent information prior to urbanization) to 1991, suggests that the most affected (contaminated) areas
coincide with that of urbanization.
