RIO DE JANEIRO, Brazil, Thursday July 28, 2016, IPS – The biggest frustration at the Olympic Games, to be inaugurated in the Brazilian city of Rio de Janeiro on August 5, is the failure to meet environmental sanitation targets and promises in the city’s beaches, rivers, lakes and lagoons.
The opportunity to give a decisive push to the cleanup of Rio’s emblematic Guanabara bay and its lagoons has been lost. The drive against waterborne pollution was part of the proposal which won the city the right to host the 2016 Summer Olympics.
This failure may hardly register in the awareness of residents and visitors, given the higher visibility of the urban transport projects and the revitalisation of Rio’s central district.
What happened confirms the national tradition of giving sanitation low priority on the government agenda. So far only half the Brazilian population has access to piped water, and only a small proportion of transported water is treated.
“The environment pays no taxes and neither does it vote, therefore it does not command the attention of our political leaders nor of society as a whole,” complained biologist Mario Moscatelli, a well known water issues activist in Rio de Janeiro.
Water Not Treated
The Olympic Park, which is at the heart of the Games of the XXXI Olympiad, was built on the west side of the city on the shores of Jacarepaguá lagoon, yet not even this body of water has been adequately treated. Filthy water from rivers and streams continues to flow into it all the time, Moscatelli told IPS.
Most of the foreign Olympic athletes and spectators from abroad will arrive in Rio at Antonio Carlos Jobim international airport, also known as Galeão. Planes touch down here on the edge of one of the most polluted parts of Guanabara bay, although visitors may not realize it.
The airport , on the western tip of Ilha do Governador (Governador Island), which was home to 212,754 people in 2010 according to the official census, is close to canals taking untreated effluent and rubbish from millions of people living on the mainland, brought by rivers that are little more than open sewers.
Guanabara bay receives 90 tonnes daily of rubbish and 18,000 litres per second of untreated waste water, mainly via the 55 rivers and canals that flow into it, according to Sergio Ricardo de Lima, an ecologist and founder of the Bahia Viva (Living Bay) movement.
Rio’s Olympic bid announced a target of cleaning up 80 percent of the effluents reaching the bay. The actual proportion achieved was 55 percent, Sports Minister Leonardo Picciani said at a press conference with foreign journalists on July 7.
“I only believe in what I see: out of the 55 rivers in the basin, 49 have become lifeless sewers,” said Moscatelli, voicing the skepticism of environmentalists.
The 80 percent target was not realistic; completely decontaminating the bay would require 25 to 30 years and sanitation investments equivalent to six billion dollars, André Correa, environment secretary for the state of Rio de Janeiro, admitted on July 20 at the inauguration of an “eco barrier” on the river Merití, one of the polluting waterways.
The barriers are floating interconnected booms that are an emergency measure to ensure that aquatic Olympic sports can take place in some parts in the bay. Trash scooping vessels or “eco boats” collect the floating debris that accumulates against them and send it for recycling.
Seventeen eco barriers have been promised, but these will be woefully inadequate, and in any case they should be anchored where floating garbage is most concentrated, like Tubiacanga, not close to the Guanabara bay entrance where water sports will be held, Lima complained.
The barrier in the Merití river is suitably placed, in Lima’s view, but it is “palliative action only.” The real solution is to promote selective garbage collection at source, that is, in households, shops and industries, and recycle as much solid waste as possible, as stipulated by a 2010 law.
“At present only one percent of the garbage produced in the Rio de Janeiro Metropolitan Region (which has a population of 12 million) is recycled,” Lima said.
