47-55 Gracia-Sanchez, J. & Navarro-Gonzales, I. Study of hydraulics and hydrocarbon-pollution behavior of a karst aquifer in a tropical area: Yucatan Peninsula, Mexico. The results of a field investigation on hydraulic and hydrocarbon-pollution behavior in an unconfined aquifer are presented. The study was performed in a site in the peninsula of Yucatan (Mexico), the main characteristics of which are: the presence of karst and the tropical weather (hurricane zone), with substantial variations of the unconfined aquifer level. Hydrocarbon-layer thickness varies over time. Water flows very easily in contrast with hydrocarbons which flow very slowly toward monitoring wells. This fact allows us to evaluate the remediation methods already employed, as well as to recommend new strategies. The aquifer’s upper layer (1.5 m) shows high contents of pollutants, but no drinking water intake was found there. However, 2 km away, where drinking water is extracted at a depth of 40 m, no trace of contaminant was found. hydrology,Mexico
