Resumen: "Pollution of the Mexican Caribbean is mainly associated by the increase of the tourism infrastructure and poor wastewater treatment. The geomorphology and the groundwater discharges (GWD) facilitate the drag of organic matter, altering the environment. In order to evaluate the water quality and detect possible contributions of contamination by GWD, physicochemical parameters and bioindicators were evaluated in costal points and cenotes, along the Riviera and Costa Maya during October, February and June (2015-2016). According with the results the cenotes had higher concentrations of silicates and nitrates than the costal points. We identify the influence of GWD in Caleta Tankah and Tulum Pez. The isotopic values showed that the enrichment of N in the Akumal Bay and Tulum (T2), come from wastewater. The presence of fecal enterococci had overshoot the maximum allowable limit for recreational waters for the Costa Maya and Cenote Manatí. The dominance of the 2A group of nematodes in the Costa Maya is related to eutrophic environments. According to this, the Cenote Encantado, Manatí, Akumal, Chávez, and the Costa Maya did not comply chemistry or bacteriologically with the standards required by the ecological criteria and Mexican norms."
