Mexico vacationers swim at highly contaminated beaches
Mexico City - The beaches of Veracruz, Acapulco, Zihuatanejo, Puerto Vallarta, Bahía de Banderas and Compostela are registering elevated levels of contamination this vacation season.
In 22 out of 29 tourist destination beaches where the Environmental and Natural Resources Ministry (SEMARNAT, for its initials in Spanish) performed water quality tests of ocean waters, the levels of enterococcus found were greater than the threshold for health risk.
According to the most recent results of the Water Qulaity Monitoring System of Priority Beaches (SISPLAYAS, for its intials in Spanish), which were on July 11 and distributed this week, the highest levels are in Regatas, in Veracruz, with 24,196 enterococcus per 100 milliliters of water. Rincón de Guayabitos 1, of Compostela, had the same quantity and Carabalí, in Acapulco, had 7,270.
The criteria established by SEMARNAT indicate a health risk is present when the readings exceed 200 enterococcus per 100 milliliters of water.
"This level represents a 5 to 10 percent risk of gastrointestinal illness and 1.9 to 3.9 percent risk of acure respiratory infections," said Cofepris is their summer pre-vacation report dated July 6.
The levels of contamination exceed this threshold in 10 out of 10 beaches monitored in Veracruz, 5 out of 5 in Acapulco, 2 out of 2 in Compostela, 1 out of 2 in Zihuatanejo, 2 out of 3 in Bahía de Banderas and 2 out of 7 in Puerto Vallarta.
In Veracruz, 7 beaches in addition to Regatas exceed the 200 enterococcus threshold: Gaviota II, José Martí, Pelicano I, Mocambo, Tortuga II, Antón Lizardo and Villa del Mar.
In Acapulco there were 3 in addition to Carabalí: Suave, Hornos and Caletilla.
In other 4 priority beaches, Almacén in Zihuatanejo, Boca de Tomatlán and Los Muertos in Puerto Vallarta, and Sayulita in Bahía de Banderas, SEMARNAT found inadequate levels of water quality (between 100 and 200 enterococcus).
SISPLAYAS commenced opeartions in December 2008 and monitors 39 beaches considered as priorities for having shown al least one incident of a health risk per year between 2003 and 2007.
So far this year, SEMARNAT has publishes the results of 11 tests. The greatest number of beaches with health risk conditions before the July 11 test was reported on January 24, April 10 and May 29, with 4 on each occasion.
"The intention of the testing is to alert the population so they do not enter the ocean at a beach which shows higher than established levels," the report added.
However, the report does not show data for the beaches in Veracruz and Guerrero. It only considers 3 beaches in Oaxaca and 2 in Tabasco that are "outside health criteria," which it attributes to the effects of hurricane "Carlotta" and to the tropical storm season.
The monitoring of water quality at the beaches of Mexico underestimates the level of contamination that is registered at tourist destinations, said Pierre Terra, coordinator of the Greenpeace of Mexico Oceans Campaign.
The environmentalist urged the expansion of the range of pollutants measured in tests by SEMARNAT and to consider wastewater discharges into rivers that flow into the sea.
"We ask for monitoring that includes more substances, particularly persistent toxins. It is good that enterococcus is analyzed, but it is only one of hundreds of elements that are in the rivers and flow to the beaches," he said in an interview.
"Many of these substances are carcinogens and we do not know how much end up on the beaches as they are not monitored. This is only the tip of the iceberg; there is much more in the water," he said.
In Mexico, he said, only 46 per cent of sewage is treated and the authorities do little to increase the amount of treated sewage.
Veracruz, he pointed out, is the coastal state with the largest volume of untreated sewage dumped into the ocean, with more than 4,000 gallons per second.
"Of the 154 coastal municipalities of Mexico, less than one-half have sewage treatment plants. Of the 77 municipalities that have a sewage treatment infrastructure, half of them are not functioning at 100 per cent and another half have a capacity below what is necessary," he said.
