next to the punta lara fishing clubs, yesterday the water exhibited the typical green of cyanobacteria / g. nail it down
After the red alert that went on in the middle of the last heat wave, in the last hours the risk indicator for cyanobacteria in the critical points of Berisso and Ensenada dropped one notch, to orange, as reported by the Undersecretary of Resources Water of the Province.
The presence of these algae, which may contain dangerous toxins, is the reason for permanent monitoring by the Buenos Aires agency. The traffic light also has yellow (low risk) and green (no irrigation) lights.
While the maximum alert level, red, is maintained on the Quilmes coast, the points in the Region fell, one step, to medium risk, it was reported yesterday.
In this situation, all the observation areas of the official “cyan traffic light” remained: La Pérgola, El Mirador and Parador 4, in Punta Lara; Regatas Club (Santiago River), Delta Berisso (zone of the four mouths, in the Port), Port access channel, Palo Blanco, Municipal Spa and La Balandra. In the Region there is also an orange light in Magdalena.
That means “the water looks bright green on the surface and on the sand. Cyanobacteria accumulate in the water column or on the surface, but not in a continuous layer,” the Provincial Undersecretary reported.
Given the picture, it is recommended “avoid contact with green stains, wash with clean water in case of entering the river or lagoon.”
At the same time, it was requested “not to consume food that comes from the body of water. Pay special attention to children and pets.
From the body of the Ministry of Infrastructure, it was detailed that the sanitary flag indicates that there is a potential risk to health on the beach and in the water.
As specified when seeing that banner, it is recommended not to enter the water and consult with the lifeguard.
The blanket of cyanobacteria develops in areas adjacent to the water intake for purification at the Punta Lara plant. This newspaper consulted with ABSA about the incidence that these organizations could have in this process. At press time, there had been no response.
Notwithstanding this, the monitoring of the Undersecretariat of Water Resources includes a point that determines the state of the supply of network water in the capital region. Last night, it indicated “Green: No risk”. It was detailed about that that “we see the water as usual. Usual activities are not affected.
Cyanobacteria are organisms that live in water and are generally blue-green in color. Some species can be harmful to health.
In case of smelling or observing color in the water, it is recommended not to make contact and consult the nearest health center in the case of poisoning, the Provincial body indicated.
A source from the agency pointed out that although the drop in temperature indicates less chance of development for this type of algae, the process that is observed in a season with heat waves like this year will require more time to reverse. “If it doesn’t rain and the wind doesn’t change, they may remain parked. Therefore, we must wait and see how it evolves. The cold front can help, but you have to see how the other conditions evolve, ”she indicated.
Specialists in this type of organisms agree that the combination of drought and heat are decisive for the formation of what is seen as green spots. In particular, in water with little movement.
Therefore, the monitoring of the Province also reaches the lagoons of the Province.
