Experts propose measures to the situation of the estuary. Reforestation, bioremediation, and training are among the alternatives.
One of the measures to decontaminate the estuary is to use clean technologies, such as nanotechnology, a purification technique that gradually cleans the estuary with oxygen bubbles, removing contaminants such as bacteria, metals, etc.
Environment Director of the Municipality Bolivar Coloma said in a recent interview that at the end of this year the implementation of a forced aeration system in section B is envisaged (from the bridge that connects Urdesa with Kennedy and Miraflores).
Sowing in the estuary
Biologist Beatriz Pernia, a professor at the University of Guayaquil and a member of the Natural Resources Research Institute, and Xavier Salgado, founder of the Sustainable Environment organization, mangrove reforestation is one of the most viable measures to revive, oxygenate and decontaminate El Salado in a natural and, to some extent, economic way.
It should be done with red mangrove, which favors the recovery of the ecosystem and survives in flooded soils.
Education and works
Pernía and Salgado insist that the authorities should invest more in education campaigns. “We must reach out to children,” he says. “We must tell them about the importance of our resources, about the history and the species that lived there. It is important to do it because through the children that we will reach the parents.”
He also proposes to invest in the construction of more linear parks and sustainable tourism projects.
Epidemiologist Luis Triviño, a specialist in Public Health and former director of the Malaria Service, says there are bacteria and enzymes that can regenerate the site, which cleanse and digest contamination.
An additional measure, says Triviño, is phytoremediation, a decontamination technique that works through certain plants. Contaminants present in the soil, air, water or sediments can be absorbed, accumulated, metabolized, volatilized or stabilized (I).
