The peninsula is bounded on the south by the high territories of Chiapas and Guatemala; on the north, by the Caribbean Sea and on the west by the Gulf of Mexico. The area near Sierrita de Ticul reaches an elevation of about 150 meters above sea level.

. Regional Hydrogeological Characteristics The Sierrita de Ticul is a small chain of rolling hills running from the north to southeast for about 110 km, with elevations varying between 50 and 100 meters above the coastal plain and reaching an elevation of about 150 meters above sea level near Tekax., The Sierrita de Ticul is in sharp contrast with the flat topography of the peninsula and constitutes its main topographic characteristic, since it separates the karstic coastal plain located to the north from the ridges and small valleys located south of the Sierrita.

Some of these cave systems form large underground rivers where fresh and salt water mixing occurs and dissolution of the carbonate rocks occur, resulting in the formation of beautiful caletas5 , such as Xel-Ha. Groundwater quality Due to the mature karstic system, this aquifer is highly vulnerable to contamination (Marin and Perry, 1994)

These hurricanes result in large amounts of rain and the aquifer receives unusually high recharge that alters the natural quality of the groundwater by introducing a number of surface pollutants that were previously deposited on the surface of the land. Additionally, the mixing of the fresh and saltwater lens occurs because of the increase in fresh water (Escolero et al., in review)
