Modern industrial agriculture is a source of serious human poisoning and destruction of the biodiversity that sustains the entire world biological cycle.

It is known of the serious damage suffered in modern history by workers who worked in contact with the first agrochemicals, as well as those affected in areas surrounding fumigations and sprayed with these products.

Pesticides and herbicides have been the main destroyers of fauna and flora displaced from agricultural fields, as well as diseases and injuries to humans.

However, for many years the serious effect of nitrogen-based and phosphate-based fertilizers applied on a large scale for prolonged periods has been proven, which are altering the physicochemical of soils and modifying climatic and hydrological cycles, as well as the phenomenon of eutrophication of surface waters adjacent to cultivated fields.

Satellite images of the great lakes of North America as well as the death of the Aral Sea in Russia are dramatic examples of this effect.

However, giving them doesn't end there.

Recently, the toxic and probably carcinogenic power of the most widely used herbicide, glyphosate, has been officially accepted by the WHO. A substance that is sprayed almost like rain in our country without any control being applied other than the famous "agronomic recipe" and good practices that depend almost exclusively on the good will of the farmer. Only a very short time ago exclusion ordinances were enacted for the spraying of this product near urban areas, although there are studies that demonstrate the drift and atmospheric diffusion capacity of this substance at distances greater than those currently accepted as safe.

And another effect not yet considered official and en masse is leachate by percolation, where various agents are dragged from the surface by the water to the subterranean layers when filtering.

Nitrate, a primary component of synthetic fertilizers such as urea and a substance dangerous to human health due to its ability to change to nitrite, an agent of known carcinogenic power, has shown an enormous leaching capacity, mainly due to its solubility in water and other electrochemical characteristics.

The layers below and around crop fields are impregnated with nitrates after decades of exaggerated and growing applications.

It must be remembered that urea is an excess fertilizer, that is, it adds exorbitant amounts of nitrate to the soil of which plants can only absorb and take advantage of a very small portion, leaving the rest for accumulation.

It is still applied with that effect simply because it is cheap, being extracted by reforming natural gas.

The concept of "cheap" that makes us dependent on non-renewable fossil resources. Cheap while there is, until it runs out. Therefore, no matter how you look at it, these fertilizers are not a stable source of resources but a precarious one.

However, another substance that is essentially soluble in water, therefore susceptible to leaching, is glyphosate itself, the killer of plants that has already proven to be toxic to animals and men.

Its producers assure that it does not generate percolation but that its toxic power remains only in soils and vents into the air, as a strange consolation to our concern. However, there is no field study that demonstrates such a theoretical postulate with certainty.

In fact, there are already multiple positives in the analysis of glyphosate content of drinking well water in our country and around the world.

One of them is the case of the “Paso a paso” school in the town of Almada, in Pehuajó Norte, whose director Marra Cristina De Zan requested the study after observing important variations in the health and capacities of children and teachers, in December of 2015.

The study was carried out by the PRINARC Laboratory, of the Faculty of Chemical Engineering of the Universidad Nacional del Litoral of the city of Santa Fe, and resulted in a concentration of 3 +/- 1 ng / ml, being the maximum tolerable limit ( ?) a value of 0.6 ng / ml.

The school is adjacent to soybean fields and the water well has a depth of 52 m, something that is not very compatible with superficial contamination and yes with a percolating process. Similar cases have been found in the US and Spain.

At the moment there are hundreds of cities and country towns in our country whose drinking water is extracted from wells fed by water under similar exposure conditions.

Data to take into account.

It is the water we drink.
