Pollutants in aquifers may threaten future of Mexico's fast-growing 'Riviera Maya'
Date:2/6/2011

Pharmaceuticals, illicit drugs, shampoo, toothpaste, pesticides, chemical run-off from highways and many other pollutants infiltrate the giant aquifer under Mexico's "Riviera Maya," research shows.

The wastes contaminate a vast labyrinth of water-filled caves under the popular tourist destination on the Yucatan Peninsula. The polluted water flows through the caves and into the Caribbean Sea. Land-sourced pollution may have contributed, along with overfishing, coral diseases, and climate change, to the loss since 1990 of up to 50% of corals on the reefs off the region's coast.

And, with a 10-fold increase in population through 2030 expected, the problems are likely to worsen, according to research published today in the journal Environmental Pollution.

"These findings clearly underline the need for monitoring systems to pin-point where these aquifer pollutants are coming from," says Trent University Prof. Chris D. Metcalfe, Senior Research Fellow of the United Nations University's Canadian-based Institute for Water, Environment and Health (UNU-INWEH).

"As well, prevention and mitigation measures are needed to ensure that expanding development does not damage the marine environment and human health and, in turn, the region's tourism-based economy."

Dr. Metcalfe conducted the study with Patricia A. Beddows of Northwestern University, Evanston IL, USA; Gerardo Gold Bouchot of CINVESTAV Unidad Merida. Mexico; Tracy L. Metcalfe and Hongxia Li of Canada's Trent University; and Hanneke Van Lavieren of UNU-INWEH. The work was conducted with the cooperation of a local non-governmental organization, "Amigos de Sian Ka'an."

The researchers concluded that illicit drugs, pharmaceuticals and personal care products found in the groundwater at four of the five locations originated from domestic sewage.

The illicit drugs identified were cocaine and its major post-digestion "metabolite" chemical, benzoylecg
