More health risks due to deep water

In the city, 60 % of the water provides its inhabitants from a network of 470 wells in the capital, however, will be increasingly extracted in a greater depth, which can generate health risks, as it can contain heavy minerals, such as arsenic, chrome, fluoride, and selenium.

This is because excessive exploitation of the groundwater layer Mexico Valley It has accelerated that the water level in the sloping soil due to 1.6 to 1.9 meters per year. Sierra Nevada Incalli Ixcahuicopa (center).

The quality of the water is proportional to the depth that is extracted from it, that is, at a greater depth, the water temperature is higher – from 48 ° C – so it has a greater ability to solve materials, salts or heavy metals, which are combined into the water body.

He added that the groundwater is between volcanic rocks, which are “rich in iron, among other heavy metals (…) It has been documented by monitoring that was done at different times.”

The specialist explained that at the beginning of the twentieth century, the water was extracted 40 meters away, while at the beginning of the twenty -first century, the decrease in the flow, derived from the exploitation of the groundwater layer, led to holes with a thousand meters deep.

Celine Olel, a physician in Earth Sciences and researcher at the Institute of Geology at the National University of Mexico, is considered that this water “has more than 15 thousand years, the time he was in contact with the rocks and considers these rocks.

These elements can be harmful to the population if they exceed certain limits. “

Currently, the practice of extraction is presented to more than two thousand meters in Wales Saint Lorenzo Tzunko and Santa Katarina 3, where 140 liters per second, which are scheduled to provide colonies from Iztabala, in addition to the average modification and areas of Badina, in the office of the President of Talban.

Olaya said that its discovery occurred through the exploration that was conducted after the 1985 earthquake to find out the seismic response to the soil branch, which helped open the possibilities on other water sources.

In 2000, the water system at Mexico City (SACMEX), in coordination with researchers from the Unam Geology Institute, was supported by the Petróleos Mexicanos team, which dug five wells in Iztapalapa, which set the validity of San Lorenzo Tezonco, which started working in 2013, and at that time from Santanta Catrina 3, in 2017.

Since its implementation, the inconvenience has been discovered regarding water quality, which contains elements that exceeded NOM 127.

These are elements like aluminum, arsenic, iron, magnesium. In addition to Boro, which is not organized in Mexico, but internationally. There we also go beyond. “

The specialist said: The presence of these elements forced SACMEX to “transfer the flow of these deep wells to the water treatment plant in the Eastern Agriculture colony, to give them treatment before they are integrated into the initial network.”

The water that is extracted with great depths should be mixed with water that does not contain these concentrations. When dilution, we are no longer above the base and water is distributed in the population. “

However, note that if the water contains at least one pollutor, “it no longer corresponds to the base”, so in the city “the water cannot be drunk directly from the key, as is the case in other countries, because here we have mixtures of 20,000.”

Sgirpc: There was never a threat

The diesel in the drinking water from Bozo Alfonso XIII and the provision of the colonies Secretariat of Integrated Risk and Civil Protection (SGIRPC).

The reliance on a message in the X account, as he did not mention the word “diesel”, as its concentration was little, “The quantity of the discovered material was never a healthy danger, given that its focus is little.” “

On May 15, the head of Sgirpc, Myriam Urzúa, expressed frankly that the deteriorating diesel was found in the well that was definitely closed in Alvaro Obergon mayor.

Yesterday, at about 1:30 pm, in her message on the social network, Sgirpc added that “the material” has more than 40 years.

Due to the high sulfur content that was identified in the material, it was concluded that it was produced more than 40 years ago. This, because the content of the particles per million was much higher compared to what is currently produced. “
