The Mexican state of Quintana Roo’s regional authorities are involved concerning the record-high ranges of contamination they’ve found not too long ago in Cancun space cenotes. Current routine testing performed by municipal authorities has revealed that 11 cenotes (roughly 15 % of these examined) within the state’s northern area now register poor water high quality.
A set of geologic phenomena distinctive to the Yucatan Peninsula, cenotes are a linked system of mineral-rich lagoons that shaped over many millennia, freshwater-filled sinkholes fed by the underground rivers that permeate the area’s porous volcanic bedrock. Tons of of them are scattered all through the Peninsula’s lush rainforest panorama, drawing vacationers from around the globe who wish to expertise their tranquil, otherworldly magnificence.
Within the northern a part of Quintana Roo, the place Cancun is positioned—together with different common tourism locations like Costa Mujeres and Puerto Morelos—there are 71 such subterranean and surface-level waterholes, usually prized for his or her novelty as pristine pure plunge swimming pools.
The Cancun Solar reported on the current examine, overseen by Quintana Roo’s Common Directorate of Ecology, which found that essentially the most contaminated water was present in Laguna Chacmochuk (a.okay.a.

Officers stated the contaminants affecting Chacmochuk and the ten different Cancun cenotes might be traced to improperly discarded wastewater, which makes its manner down by the water. desk and into these delicate lagoons. An deserted dump web site positioned on Isla Mujeres additionally produces leachate (hazardous liquid contaminants ensuing from the combination of decomposing rubbish with rainwater) that infiltrates groundwater and seeps into close by floor our bodies of water.
Claudia Cecilia Topete Martín, supervisor on the AyMA Engineering and Environmental Consulting firm, disclosed that the main contaminants encompass phosphorus, ammoniacal nitrogen and coliform micro organism—a microbe that comes from human and animal feces.
Water high quality testing of the realm’s 71 cenotes was carried out routinely throughout the interval from 2020 to 2022, and examine websites included the municipalities of Isla Mujeres, Benito Juárez, and Puerto Morelos. No point out has been made about whether or not or not the cenotes in query are at present closed to guests, however one of many examine’s findings will inform native authorities’ motion plan for controlling future water air pollution.
Topete Martín offered concepts for among the most viable options towards continued water contamination, together with:
— Increasing the realm lined by the native sewage community
— Making certain enough wastewater remedy techniques are in operation
— Making certain correct upkeep of the realm’s drainage community, thereby stopping leaks and spillage
— Educating the general public concerning the area’s water high quality and correct wastewater disposal
On account of the examine, authorities plan on analyzing 39 native water remedy vegetation; 63 stations that monitor coastlines, lagoons, cenotes and groundwater; a visitors gentle system for reporting on water high quality; and as much as 19 discharge websites to the Nichupté lagoon system.
